The Impact of Israeli and Saudi Arabian Geopolitical Risks on the Lebanese Financial Market

: Hezbollah is best deﬁned in geopolitics as the Iranian ideology proxy that aims to grow the Persian footprint and to gain geopolitical strategic depth in the region. Its role continuously requires geopolitical conﬂicts, mainly against Saudi Arabia and Israel—for resistance, ideological, and geopolitical purposes. Being a state within a state, Hezbollah militia makes sovereign geopolitical decisions and forces Lebanon to pay for the consequences. This is the ﬁrst economic study that empirically investigates under vector autoregression (VAR) models the dynamic causal relationship between Saudi Arabia and Israel’s geopolitical risks and Lebanon’s ﬁnancial stability and economic activity. The results show that Saudi Arabia and Israel’s geopolitical risks affect Lebanon’s economy differently. Economic and ﬁnancial stability cannot be promoted independently of regional geopolitical conﬂict.


Introduction
The Middle East and North Africa region is currently witnessing changes toward the deal of the century. It is promoted by Israel's normalization with many Arab countries such as the United Arab Emirates, Bahrain, Sudan, Qatar, and Morocco (and probably Saudi Arabia and Oman). Despite the historical maritime border talks between Lebanon and Israel that have started in October 2020 (and still ongoing), its success is not guaranteed. In fact, it is extremely challenging to predict geopolitical changes in Lebanon under Hezbollah's domination.

Hezbollah, Israel, and Saudi Arabia: Geopolitical Background
Founded in 1982 by Iran, Hezbollah's-the Islamic resistance army-mission was exclusively to liberate the Israeli occupation of southern Lebanon. Paradoxically, in May 2000, when the Israeli military army withdrew from Lebanon, Hezbollah "theoretically" lost the legitimacy to keep its weapons (UNSCOL [2004(UNSCOL [ ] 2006. For that, Hezbollah had to wear many hats, all under the resistance umbrella: it positioned itself as a resistant militia (1) to defend the Palestinian cause against Israel, (2) to protect southern Lebanon from future Israeli attacks, and (3) to weaken Saudi Arabia's regional influence for ideological rivalry. Regardless of its declared resistance agenda, Hezbollah is nothing but Iran's proxy that behaves at its behest (DeVore 2012; Seliktar and Rezaei 2020) to gain geopolitical-strategic depth in the region.
Since ideology, civilization, religion, and geopolitics appear complementary (Kuçi 2020;Sheikh 2003). Hezbollah had to accumulate an array of sophisticated armaments, rockets, and weapons. It has also expanded tens of thousands of trained fighters in order to spread ideological-Welayat Al-Faqih-ethnic grounds far and wide (Salamey and Othman 2011;Al-Aloosy 2020) no matter the devastation caused, as long as it increases the Persian footprint (Haddad 2006;Jones 2019). Yemen, Iraq, and Syria are testimonies of the poverty, starvation, corruption, and terrorism caused by Hezbollah's invasion under

Research Question and Hypothesis
The consequences of Hezbollah's underground activities and geopolitical tensions are bore by Lebanon (the country). It would be valuable to assess empirically the impact of Saudi Arabian and Israeli geopolitical threats with Hezbollah on the Lebanese financial market. It goes back to 1997 when Schrodt (1997) tried to create an early warning indicator of geopolitical risks between Israel and Hezbollah (in the south of Lebanon) to forecast future conflict and to help policymakers avoid financial crises. However, his study lacks precision due to data limitations.
Although the literature is abundant in political science regarding Lebanese geopolitics, it remains rare, if not inexistant, in economics and econometrics. Instead, studies are rather press releases, newspaper articles, or economic reports elaborated by the United Nations, Reuters, the World Bank, or other international organizations. These publications are somehow descriptive and merely limited to estimating the cost of reconstruction (after a war) or to exposing in value the costs and losses of geopolitical conflicts on education, welfare, agriculture, and employment.
This paper aims to investigate empirically-on a monthly basis, from June 2000 (after Lebanon deliberation) to November 2018-the dynamic causality-independence between geopolitical risks of Israel and Saudi Arabia (towards Hezbollah) and the Lebanese financial market.
This study employs Granger causality tests under vector autoregression (VAR) models, followed by first-orthogonalize-Cholesky decomposition-impulse response functions and variance decomposition of variables to detect the dynamic relations between Israeli and Saudi Arabian geopolitical risks with the Lebanese financial market and economic activity.
This study aims to achieve one of two possible conclusions: If the Lebanese financial market shows independency or low dependency-causality to the regional geopolitical risks, then Hezbollah's geopolitical tensions with Israel and Saudi Arabia do not seem to negatively affect the Lebanese financial stability. Consequently, economic reforms, monetary and fiscal policies, as well as internal legal reforms can be improved independently from the geopolitical, international, and diplomatic arrangements.
If the Lebanese financial market shows significant dependency-causality to the regional geopolitical risks, then Hezbollah's tensions with Israel and Saudi Arabia trigger the Lebanese financial stability and economic activity. Therefore, instead of solving the Lebanese economic crisis from a purely economic perspective, measures towards negotiation and conflict resolution with the neighborhood are needed, which require de-Hezbollizing Lebanon.
One would find it evident that geopolitical risks negatively affect the financial stability and economic activity; however, the literature shows different conclusions depending on the country's category, income level, and even polity.
The remainder of the paper is structured as follows: Section 2 includes a literature review. Section 3 describes the data and statistical tests. Section 4 illustrates the graphical analysis with preliminary deductions. Section 5 exposes the methodology. Section 6 interprets and discusses results and findings. Section 7 closes with a conclusion and recommendations.

Literature Review
Analyzing Geopolitical Risks' (GPR) economic consequences remains essential for policymakers, portfolio managers, firms, and international institutions to update their forecasting and risk assessment efforts (Hendrix 2019). Accordingly, to predict political behavior phases during conflicts in the Middle East region, Schrodt andGerner (1997, 2004) tried to elaborate a geopolitical early-warning indicator, using several statistical techniques. With the upsurge in terrorist attacks, regional wars, and new form of collective violence, a growing number of scholarly interests focus on assessing geopolitical risks' (GPRs) impacts and consequences.

Geopolitical Risks and Economic Activity
Some of the literature empirically examines the GPR's impact on per capita GDP growth. For instance, Eckstein and Tsiddon (2004) used vector autoregressive (VAR) models to study the impact of geopolitical risks on the economy. They found a significant negative impact on GDP per capita that exceeds 2% in some countries, such as Israel. According to Tavares (2004), geopolitical risks, or more precisely terrorism, may have a small negative impact on per capita GDP growth. However, his findings become insignificant once he has added determinants of growth, such as education, trade openness, and inflation rate. Unlike Tavares (2004) findings, Gupta (2008) reported that country risk does not seem to negatively affect per capita income growth in low-and middle-income countries but rather has an indirect negative impact on the economic growth by increasing the defense-spending share of the government.
Several scholars examined the impact of GPR on the economic activity (Cepni et al. 2020;Saint Akadiri et al. 2020;Cheng and Chiu 2018). They employed structural VAR models and time-varying multivariate causality and then concluded that the geopolitical shocks in the emerging countries are associated with significant economic contractions.
Instead of exploring economic growth response to GPR shocks, a wide array of studies rather focuses on breaking down the economic activity and examining its sectors' and/or components' response to GPR shocks. For instance Gupta et al. (2019) verified the impact of GPR on trade flows. They considered GPR in a gravity model, with fixed effect-random effect, Hausman Taylor, and Poisson Pseudo-Maximum Likelihood, and then, they found that GPR negatively affects the trade flows.
Saint Akadiri et al. (2020) studied the impact of geopolitical risks on the touristic sector and the GDP growth in Turkey. Using Toda-Yamamoto's version of the Granger causality, he founds a unidirectional causality running from geopolitical risk index to economic growth and from geopolitical risk index to tourism. Other researchers examined specifically the terrorism impact (among other geopolitical component variables) on the touristic sector in the long run and the short run. A. Liu and Pratt (2017) considered the global terrorism index to analyze the relationship between terrorism and tourism in 95 countries using the autoregressive distributed lag (ARDL) model. They found that, in the long run, for the large majority of destinations, terrorism has a minimal impact on tourism demand (except for nine countries out of 95). However, significant short-run impacts of terrorism were found in 25 individual destinations including Israel and Turkey. Similarly, Karamelikli et al. (2020) used a nonlinear ARDL impact of terrorism on the incoming and domestic tourism in Turkey. They found that terrorism affects differently the inbound and domestic tourists in the long run and in the short run.
According to Hamadeh and Bassil (2017), who studied the impact of terrorism on the touristic sector in Lebanon, European tourists appear to be less sensitive to terrorist attacks than Arab tourists. Seabra et al. (2020) concluded that terrorist attacks in one country can have a positive or a negative impact on the touristic sector in other countries. For instance, terrorist attacks that take place in Israel and Greece seem to negatively affect tourist arrivals from Africa in Portugal, while attacks perpetrated in other countries positively influence arrivals in the country.
Additionally, researchers such as Eckstein and Tsiddon (2004) and Sandler and Enders (2008) examined the way GPR's tendencies varied in different categories of countries. They demonstrated that the causality between geopolitical risks and economic growth depends on the economy's type. In other words, the economic activity of developed, emerging, and developing countries respond to GPR shocks differently. Furthermore, Das et al. (2019) tested the dynamic causality of GPR on macroeconomic variables, using threshold VAR models and found several shock impacts across different market states. Similarly, Tavares and Wacziarg (2001) and Tavares (2004) advocated the asymmetric impact of GPR among economies. By comparing the costs of terrorism in democratic versus non-democratic countries, they found that a higher level of democracy could act as a buffer against terrorist attacks and could better recover from the GPRs.

Geopolitical Risks and the Financial Market
Economists argue about GPR measurement, which lacks accuracy in econometricempirical studies. In fact, similar to in politics, variables in geopolitics that represent social-human behavior are rather qualitative. They are available only for a few years and are usually binary-discrete (i.e., reported with numbers ranging from one to five or with very little variability). In 2018, Caldara and Iacoviello (2018) constructed a revolutionary GPR index, a more developed version of the GPR index previously elaborated by Chadefaux (2014), Saiz and Simonsohn (2013) and Baker et al. (2016), best conceived in time series analysis. It is a continuous index (rather than discrete), which is delivered on a monthly basis, since 1985. Since the new GPR was launched in 2018, researchers' appetites to examine and empirically assess the relationship between the GPR and the financial-stock market has jumped significantly. Das et al. (2019) approved of this index being more specialized. It captures specific events and is expected to have an explicit impact on the financial variables.
Accordingly, Apergis et al. (2018), Bouras et al. (2019), and Lee (2019) verified the GPR impact on stock market volatility, using Granger causality tests, panel generalized autoregressive conditional heteroskedasticity (GARCH), and the copula approach, respectively. They found an overall significant positive impact with minor differences that are related to the model or the countries' details. Mansour-Ichrakieh and Zeaiter (2019) also investigated the dynamic causality between Saudi Arabia and Russia's GPRs on the Turkish financial market. Using threshold VAR, they found that the Turkish financial market is more sensitive to Saudi GPR and can even change the financial market's state from low-stress level to high-stress level. Bouoiyour et al. (2019) employed a flexible Markovswitching dynamic copula approach to examine the dynamic response of the oil market as a nonlinear-switching phenomenon to geopolitical risks in different scenarios: low and high risks. They found that oil price appears to respond to GPR shocks strongly and positively.
Similarly, Plakandaras et al. (2019) and J. Liu et al. (2019) verified the GPR causality on oil prices and the financial liquidity by running dynamic model averaging, a means of wavelet analysis, on Saudi Arabia and by employing GARCH and Mixed Data Sampling model (MIDAS). They found an overall similar conclusion (with minor changes in each study), that the oil price and the domestic liquidity seem to respond to GPR shocks. Likewise Cunado et al. (2020) employed a time-varying parameter structural VAR model to verify the dynamic relationship between GPR and oil price in the Middle East. They confirmed that higher GPR shocks drive the oil prices upwards. As for Al-Yahyaee et al.
(2019) and Aysan et al. (2019), they focused on analyzing bitcoin's value responsiveness (return or volatility) to GPR. By using a bivariate and multivariate wavelet approach and Bayesian Graphical Structural VAR technique, respectively, a positive relation was revealed.
The present paper empirically investigates, for the first time, the impact of Israeli and Saudi Arabian geopolitical risks (toward Hezbollah) on the Lebanese financial market stability and economic activity.

Data
Data are reported on a monthly basis from June 2000 to November 2018 and in percentage growth. Their growth-pattern time-series are reported in Figure 1. All variables are taken in growth pattern. Positive fluctuations indicate high financial stress, high geopolitical threat periods, depletion of Foreign reserves (FX), or economic recession, while negative fluctuations indicate the opposite. Covariance stationarity is observed graphically. However, traditional tests such as Augmented Dickey Fuller (ADF) and Phillips-Perron (PP) tests are needed to verify the stationarity of variables.

The Financial Stress Index (FSI)
Through the literature, the Financial Stress Index (FSI) is the most common index used to empirically test the dynamic relationship with economic variables. The Lebanese FSI follows the methodology of Cardarelli et al. (2009) and Balakrishnan et al. (2011), but it is developed and tailored by adding the dollarization rate to better represent a dollarized country (Ishrakieh et al. 2020b(Ishrakieh et al. , 2020a. It includes the main early warning indicators of each of the banking sector, the stock or equity market, and the foreign exchange and debt markets. It was constructed by on a monthly basis from January 1998 to January 2018 but has not been employed econometrically yet (the FSI data are available online at https://data.mendeley.com/datasets/sc7hmvcmjf/2, accessed on 1 December 2020).
The present paper studies the period after the complete Israeli withdrawal from occupied territories (from June 2000). The FSI is modified by removing the weighted average cost of capital and the inverted yield because their weights are zero. The FSI is updated to November 2018 and data are available online with this study. The FSI does not include any structural breaks, not even during the 2008-global subprime crisis, since the crises transmission channels through the equity market or via the exchange rate are insignificant (the de facto Lebanese pound is not floating but pegged to dollar). Moreover, the equity market is relatively tiny. The most informative market in Lebanon that fluctuates with panic of economic agents remains the foreign and exchange markets.

Business Cycle
There are several techniques to determine and define the business cycle as Škare and Stjepanović (2016) illustrate in a comparative table. Most researchers (Balakrishnan et al. 2011;Cardarelli et al. 2009;Cevik et al. 2016;Davig and Hakkio 2010) consider the business cycle that follows the Harding and Pagan (2002) methodology. In Lebanon, the business cycle is determined by Jad (2017), following the Bry and Boschan (1971) methodology.

Economic Activity (ECO)
The Industrial Production Index (IPI) and the Gross Capital Stock (GCS) are the most used in the literature as a proxy of the Gross Domestic Product (GDP) (Kaminsky and Reinhart 2002;Reinhart and Rogoff 2009;Demetriades et al. 2017). In Lebanon, all of the GDP, IPI, and GCS data are available on a yearly basis and/or for a few years. Accordingly, in the present study, employment in the private sector was taken as a proxy for economic business cycles or economic activity (ECO). Table 1 exhibits the correlation between GDP, GSC, and ECO that is reported on a yearly basis and seasonally adjusted by the Federal Reserves-Saint Louis. The ECO sign is inverted so positive values indicate economic contraction and vice versa. The correlation between employment in the private sector and the constant GDP reaches 88 percent. Since in Lebanon monthly data of GDP, IPI, and GSC are unavailable, employment in the private sector that is calculated on a monthly basis is taken as a proxy for GDP to express the economic activity.

Geopolitical Risks (GPR)
The Geopolitical Risk (GPR) index is taken from Caldara and Iacoviello (2018). It is a continuous variable (rather than discrete) normalized to 100 and reported on a monthly basis, from 1985 to September 2018 (The index was last time updated in November 2019 and is available on https://www.matteoiacoviello.com/gpr.htm, accessed on 1 December 2020). It is elaborated from various newspaper articles covering geopolitical tensions and examining the evolution and effects that best reflect geopolitical risks, military-related tensions, nuclear tensions, war threats, terrorist threats, and the beginning of war. The GPR index also encompasses mass-social media and messages delivered through TV speeches, interviews, newspapers, and other media campaigns. It is elaborated for many developed and emerging countries.

The Adequate Level of Foreign Reserves in a Dollarized Country (FXFXD)
The innovative character of this study's data is in the choice of the adequate level of FX, that best suits a dollarized country like Lebanon. All previous studies investigating Lebanon or including Lebanon in a panel with other countries use general measurements of FX (such as the FX to gross domestic product ratio, or the FX to broad money ratio, or the FX to import ratio, or the FX to short-term external debt ratio). More often, researchers consider the Guidotti-Greenspan Rule, that measures total foreign reserves over short-term external debt. Although considered the rule of thumb, the Guidotti-Greenspan Rule lacks accuracy in a dollarized country. In fact, Gonçalves (2008), Soto and García (2004), Durdu et al. (2009), andCalvo et al. (2008) found that the money demand in foreign currency of a dollarized country is highly correlated with the sudden stop and the systemic crises. In the 2017-IMF country report for Lebanon, Ahuja et al. (2017) stated that "A common shock to bank liquidity, leading to a demand for foreign currency, could result in a drop in international reserves (1 percent of deposits are equivalent to 3.7 percent of reserves)". Accordingly, a more adequate level of FX is suggested by Gonçalves (2008) which is the ratio of FX to Deposit in Foreign Currency (FXFXD). Data are taken from the central bank of Lebanon. The FXFXD sign was inverted, so an increase in the ratio becomes a threat.

Statistics
Descriptive statistics and correlations of variables are reported in Tables 2 and 3.

Graphical Analysis and Preliminary Deductions
It appears common that the aforementioned authors interpret graphically the FSI spikes with the business cycle before proceeding with empirical models. FSI fluctuations are represented in Figure 2. Recession periods are reported in the shaded areas. Graphical analysis shows that most of the economic and political trouble trigger FSI at a low level (below the stress level). They are mainly triggered by credit rating downgrading (in May 2008, February 2011, May 2012, November 2013, December 2014, and September 2015; by the central bank's interventions through financial engineering (in May andAugust 2016 andin September 2017); or by internal political trouble such as conflict between political parties, government members' resignation (January 2011, February 2015), or election delays (2014)(2015)(2016).
On the other hand, most FSI high spikes that surpass the stress level seem to be associated with regional geopolitical threats. High fluctuations that are reported in positive values indicate stressful periods/financial crises, while low fluctuations reported in negative values indicate low stress periods. The stress level is represented by 1.5 times the standard deviation of the FSI.
Graphical analysis shows that most of the economic and political trouble trigger FSI at a low level (below the stress level). They are mainly triggered by credit rating downgrading (in May 2008, February 2011, May 2012, November 2013, December 2014, and September 2015; by the central bank's interventions through financial engineering (in May and August 2016 and in September 2017); or by internal political trouble such as conflict between political parties, government members' resignation (January 2011, February 2015), or election delays (2014)(2015)(2016).
On the other hand, most FSI high spikes that surpass the stress level seem to be associated with regional geopolitical threats. For instance, the dates April and October 2000, April 2001, and July 2006 detect tensions with Israel. In July 2006, few years after the Israel-Lebanon ceasefire, Lebanon faced a one-month-destructive war with Israel. Nevertheless, Israel responded to Hezbollah attacks (Sharp et al. 2006) rather than attacking Lebanon. It is stated in Schmitt (2007) that "Israel did not attack the government of Lebanon, but rather Hizbullah military assets within Lebanon".
The two most severe financial crises with the highest spike levels were hit in February 2005 when the Lebanese prime minister named Hariri was assassinated and in November 2017 when the Lebanese prime minister, Hariri Junior, was detained in Saudi Arabia and was forced to resign. In appearance, these dates seem to be caused by internal political trouble. In reality, the Hezbollah is in the details: In October 2020, the Special Tribunal for Lebanon-United Nations Security council resolution 1757 declared that the prime minister was assassinated in February 2005 by a terrorist attack from a member of Hezbollah. Similarly, in November 2017, Saudi Arabia detained the prime minister as an expression of its disagreement toward Hariri Junior's cooperation with the Hezbollah political party.
The graphical analysis presumes that high FSI spikes are related to the regional geopolitical tensions with Hezbollah whereas local political or economic pressures are not.
Similarly, it appears that most of the recession periods overlap positive high FSI spikes. Nevertheless, empirical tests are crucial to verify the preliminary deductions.

Methodology
VAR is a natural framework for examining Granger causality, commonly employed by macroeconomists to characterize the joint dynamic behavior of variables such as geopolitical risks with other macroeconomic variables. Similarly, Impulse-Response Functions measure the dynamic marginal effects of each shock on all of the variables over time. Finally, the variance decompositions examine how important each of the shocks is a component of the overall (unpredictable) variance of each of the variable over time.

Preliminary VAR Steps
VAR times-series analysis first requires verifying that all variables are stationary then choosing the appropriate lag length criteria.

Stationarity
Variable stationarity is tested with Augmented Dickey Fuller (ADF) and Phillips-Perron (PP). The results are reported in Table 4.

Lag Length Criteria
The literature analyzing the choice of the appropriate VAR lag length criteria is vast. However, the aforementioned authors (Cf. section literature review) have chosen the traditional Akaike Information Criterion suggested by Akaike.
The lag order selection criteria of the sequential modified (LR) test statistic, the Final Prediction Error (FPE), Schwarz information Criterion (SC), Hannan-Quinn information criterion (HQ), and the Akaike Information Criterion (AIC) are reported in Tables 5-8.

Vector Autoregressive Model-VAR, Residual Serial Correlation, and Granger Causality Test
The VAR model is conceived to capture dynamic interactions among the variables undertaken. The cause-and-effect relationship among variables can be verified under the Block Exogeneity Wald framework. For instance, if past values of one variable such as FSI helps predict future values of another variable such as ECO, then it is said that FSI Granger causes ECO or that ECO is affected by FSI. The simple Granger causality test considers only two variables, and it is expressed in the following way: where ECO t and FSI t are the growth rate of ECO and FSI in time t, ECO t−i and FSI t−i are the growth rate of ECO and FSI in time t − i, and ε and ҙdenote error terms. Based on both Ordinary Least Squares (OLS) coefficient and significance, possible cases obtained are: Unidirectional Granger causality from FSI to ECO or from ECO to FSI means that one variable increases the prediction on the second variable but not vice versa.
Bidirectional causality is where ECO predicts FSI and FSI predicts ECO too. Independence between ECO and FSI indicates absence of Granger causality. Granger causality is often tested in a context of model. Since omitted variable bias might cause problems, this paper considers VAR models or n− equation VAR with nvariable linear system in which each variable is a linear function of its own lagged values and past values of the remaining n-1 variables (Stock and Watson 2001). A VAR model has at least three variables. Given Y t , the vector of variables, the classical VAR model becomes: where Y t is an m × 1 vector of the endogenous variables and u t is an m × 1 vector of the error terms in Equation (3). p is the number of lags that adequately models the dynamic structure. The coefficients of further lags of variables are not statistically significant, and the error terms are white noise. The error terms may, however, be correlated across equations. If the p parameters are jointly significant, then the null hypothesis that states that one variable (x) does not Granger cause the other variable (y) can be rejected. Similarly, if the p parameters are jointly significant, then the null hypothesis that states that one variable (y) does not Granger cause the other variable(x) can be rejected.
In this study, the dynamic relation between FSI, FXFXD, and ECO is first verified. Then, the possible dynamic relation between regional geopolitical risks and the Lebanese financial market is tested so the VAR model considers four variables: Israel GPR, Saudi Arabia GPR, FSI, and FXFXD. Finally, the VAR is run twice, as a robustness check, by including each time one GPR (GPR of Israel or Saudi Arabia) and excluding the other one.

Residual Serial Correlation
The VAR residual serial correlation-Lagrange Multiplier (LM) tests are performed in Tables 9-11 to assess the validity of VAR regressions and to make sure the null hypothesis of the absence of autocorrelation in lag given by AIC at 5% is accepted. The null hypothesis of no residual autocorrelation is not rejected at conventional significance level. The null hypothesis of no residual autocorrelation is not rejected at conventional significance level.

Impulse-Response Functions and Variance Decompositions of Variables
The Impulse-Response Functions (IRFs) aim to analyze the dynamic effects of the system when the model receives an impulse or an exogenous shock on the dynamic path of the variables of each estimated VAR. The departure point of every IRF for a linear VAR model is its moving average (MA) representation, which is also the Forecast Error Impulse Response (FEIR) function Φ i for the ith period after the shock is obtained by with Φ 0 = I k , K is the number of endogenous variables and p is the lag order of the VAR. The off-diagonal elements of the estimated variance-covariance matrix is not zero; therefore, a contemporaneous correlation between the variables in the VAR model would exist. In this study, the IRFs consider some restrictions on the VAR errors to address possible contemporaneous correlations that residual impulses ignore: the Cholesky decomposition method. The Cholesky decomposition method isolates the structural errors by recursive orthogonalization. Further information on contemporaneous relationships can be introduced to the FEIR by simply multiplying it by a matrix F: The orthogonal impulse response functions consist of decomposing the variancecovariance matrix so that ∑ = PP', where P is a lower triangular matrix with positive diagonal elements, which is often obtained by a Cholesky decomposition. The latter requires placing variables of interest on the basis of the speed at which the variables act in response to shocks. Accordingly, the variables placed higher in the ordering have contemporaneous impact on the variables lower in the ordering. However, the variables placed lower in the ordering do not have a contemporaneous impact on the variables higher in the ordering.
The corresponding orthogonal impulse response function is then: This study considers the GPR of Israel to have a greater impact; hence, it is first orderedorthogonalized in IRFs. The response of ECO to FSI and to other variables (combined) are reported in Figure 3. The combined response of FSI and FXFXD to GPR shocks are reported in Figure 4. The global multiple VAR model IRFs are reported in Figure A1.

Variance Decompositions of Variables
The variance decomposition of variables shows the portion of variance in the forecast error for each variable due to innovations to all variables in the system (or when a shock is given to one variable). Variance decompositions are represented graphically in Figure 5 and numerically in Table A1 in Appendix A.

Results and Discussion

Results and Discussion
After verifying in Table 4 that all variables are stationary and after verifying in Tables 9-11 the absence of residual serial correlation in lag given by AIC, this section aims to interpret results obtained from running Granger causality tests under VAR models, impulse response functions, and variance decomposition of variables. Table 12 exhibits the results obtained from the multivariate Granger causality tests under VAR models between FSI, ECO, and FXDFX at lag 2 ( Table 5). The results show a unidirectional causality from FSI to ECO significant at five percent. There is strong evidence that FSI helps predict output (proxied by employment in the private sector) within two months, while the opposite direction is not true since the p-value is 0.64.
In other words, in Lebanon, a high a financial stress is powerful enough to Granger cause economic recession. The results are consistent with Illing and Liu (2003), and Cardarelli et al. (2009). Indeed, the financial market stability promotes economic growth through facilitating credit conditions, encouraging investments and purchases, as well as ensuring better expectations in the long term (Durusu-Ciftci et al. 2017;Cheng and Chiu 2018). Financial stability can even contribute to reducing poverty because changes in investments and economic activity growth (that are generated by financial stability) tend to increase more proportionally (Beck et al. 2007;Burgess and Pande 2005). A few studies found the causality from ECO to FSI to be significant. For instance, Kaminsky and Reinhart (2002), Mendoza and Terrones (2008), Calvo and Talvi (2005) and Reinhart and Rogoff (2009) found that a financial crisis is inevitable after a recession. Table 12 also illustrates a bidirectional causality between the FX and the FSI at lag 2, which means that the FSI can predict future FXFXD shock and vice versa within two months. It sounds logical that FXFXD shocks cause FSI. In fact, FX are vital in a dollarized country; they guarantee a better exchange rate stability (Calvo 2006). They are considered auto-insurance against future financial crises (Calvo and Reinhart 2000). This explains the "psychological impact" behavior of post-crisis emerging countries holding excessively "too much of good thing" (Jeanne 2007;Obstfeld et al. 2009).

FSI and FXFXD Bidirectional Causality: FXFXD ↹ FSI→ECO
The FXFXD-FSI bidirectional causality is highly significant when the VAR model includes GPRs (with p-value = 0.00 in Tables 13 and 14) and barely significant internally (pvalue = 0.08 in Table 12), which indicates that, when uncertainty in the financial market (FSI) occurs (especially that resulting from geopolitical tensions), economic agents look after converting local currency to foreign ones (FXFXD). Consequently, FX depletion arises and then causes a more severe financial crisis (FSI) that ends up with an economic contraction (as verified previously that FSI causes ECO. The deduction seems consistent with the IMF country report for Lebanon by Ahuja et al. (2017) who stated that "A common shock to bank liquidity, that leads to a demand for foreign currency, could result in a drop in international reserves (1 percent of deposits are equivalent to 3.7 percent of reserves)". Table 13 reports the Granger causality relation between Israel, Saudi Arabia GPRs, FSI, and FXFXD at lag 6. (Table 14A verifies the dynamic relation by excluding from the VAR model the GPR of Saudi Arabia.) The results reveal a unidirectional causality from Israel GPR to FSI (the p-value is 0.066 in Table 13, and the p-value is 0.04 in Table 14A). Accordingly, Israel GPR seems to Granger cause a future financial crisis in Lebanon within six months. Similarly, the results in Tables 13 and 14 exhibit strong evidence that FSI helps predict FXFXD (p-value = 0.00) and overwhelming evidence that FXFXD helps predict FSI (p-value = 0.00). The bidirectional relation between FSI and FXFXD is aligned with previous results.

Israel GPR, Saudi Arabia GPR, FSI, and FXFXD Causality: Israel GPR→FSI
The Israel GPR starts Granger causing FSI who triggers FXFXD, which in return FXFXD leads to a deeper financial crisis (FSI) and ends with economic contraction. The findings seem consistent with previous deductions derived from the graphical analysis.

Remark and further analysis It should be noted that the results indicate that Israel and Hezbollah's threats can trigger a financial crisis in Lebanon. However, the results do not specify whether threats are generated from Israel or from Hezbollah, unless a Hezbollah GPR index is constructed. Regardless, a tit-for-tat between Israel and Hezbollah (in Lebanon) exists; geopolitics is not necessarily expressed by military or terrorist attacks but through several media channels: never underestimate the power of words in hate radio speeches that mobilized people to FSI→ECO   Table 12 also illustrates a bidirectional causality between the FX and the FSI at lag 2, which means that the FSI can predict future FXFXD shock and vice versa within two months.

Remark and further analysis It should be noted that the results indicate that Israel and Hezbollah's threats can trigger a financial crisis in Lebanon. However, the results do not specify whether threats are generated from Israel or from Hezbollah, unless a Hezbollah GPR index is constructed. Regardless, a titfor-tat between Israel and Hezbollah (in Lebanon) exists; geopolitics is not necessarily expressed by military or terrorist attacks but through several media channels: never underestimate the power of words in hate radio speeches that mobilized people to commit genocide in Rwanda.
The social media platforms are indeed an important army channel for Hezbollah to raise risks or to prevent Israel from achieving its goal (Kalb and Saivetz 2007). Hezbollah's speeches and video messages have been extensively analyzed and interpreted in the literature.
Hezbollah seems to take advantage of the Israeli financial market (Tel Aviv stock market) sensitiveness to geopolitical risk-terrorist-suicide attacks (Eldor and Melnick 2004) in order to develop its geopolitical skills through media coverage. Accordingly, Jetter (2017), who analyzed the causality-relation between terrorist attacks and media coverage, mainly in The New York Times, concluded that Israel as well as Iraq and Colombia are more likely to respond to news than other countries.
Interestingly, Yarchi (2016) considered it strategic for Israel to be relatively weaker than Hezbollah in spreading geopolitical risks through media platforms. In fact, a wider broadcast of Israeli military attacks would increase the visibility of killed Palestinian civilians, which would trigger a widespread movement of sympathy and would raise the international voices demanding to stop Israeli attacks. Likewise, Israeli attacks on Palestinians tend to be committed when voters of the US are preoccupied by events (Durante and Zhuravskaya 2015).
On the other hand, social media and campaigns are not only limited to broadcasting Hezbollah's resistant military attacks but also to spreading its ideology and civilization considered as complementary to geopolitics (Kuçi 2020). Hezbollah employs all media platforms (through their own TV channels, radios, and websites) to promote its militia wing and to create a distinguished "brand image of terrorism" (Matusitz 2018). Hezbollah (resistance ideology) leaders' speeches and videos are translated in many languages and accessible all over the world, aiming to reach a wider audience. Many of them are perceived as being a resistance ideology "show-off" rather than triggering geopolitical risks to please its supporters and grow popularity (El Houri and Saber 2010). Moreover, they strive to educate their audience in several fields such as history, culture, music (religion and resistant songs), politics, religion, and beliefs as they are perceived by Hezbollah, the Iran's proxy (Weimann 2008). Likewise, Nilsson (2020) conducted a qualitative frame analysis of Hezbollah's speeches and found that they follow a diversity strategy. They are framed differently depending on the target: diversity of resistance, normalization of resistance, and social dimensions of resistance. In short, while both Israel and Hezbollah's military wings play geopolitics, Lebanese bears economic consequences.  FXFXD Surprisingly, Tables 13 and 14B indicate that none of Saudi Arabia GPR's coefficients are significant (p-value > 0.1). Saudi Arabia seems to predict neither directly a financial crisis nor indirectly the FXFXD shocks. Saudi Arabia's geopolitical threats toward Hezbollah (in Lebanon) are not powerful enough to destabilize the Lebanese financial market as it does with Turkey. For instance, Mansour-Ichrakieh and Zeaiter (2019) proceeded with a similar empirical analysis between Saudi Arabia GPR and the Turkish financial market, concluded that the Saudi Arabian GPR can trigger severe financial crisis in Turkey and can even change its state (threshold) from a low stress level to a high stress level.

Saudi Arabia GPR, FSI and FXFXD: Saudi Arabia GPR
The findings raise the question on whether Saudi Arabia considers Turkey a nation competing at the ideology, economic, and military levels (Grumet 2015; Janine 2018) as more dangerous than Hezbollah.

•
Remark and further analysis In 2012, Saudi Arabia (followed by other gulf countries) announced a cold war against Hezbollah's terrorist attacks and military intervention in Syria. The cold war is expected to negatively affect the Lebanese economy through the touristic sector. It was verified by Hamadeh and Bassil (2017) that geopolitical risks, and more precisely terrorist attacks in Lebanon, have a greater negative impact on Arab tourists than on European ones.
On the one hand, 40 percent of the total Lebanese migration are expatriate labor in Arab countries and around 20 percent of total Lebanese migration or 160,000 are employed in Saudi Arabia (De-Bel-Air 2017). They send remittances equivalent to about 5 billion dollars per year (about 11 percent of GDP). Consequently, the Gulf remittances' losses can reduce GDP and increase the unemployment rate to about seven percent (Ghaddar 2017).
On the other hand, (Ghaddar 2017) reveals that Saudi Arabia contributes to about 25 percent of all visitor tourists. When Saudi Arabia decided to boycott Lebanon at economic and touristic levels, the tourism loss hurts the hotel sector, driving down occupancy to about 40 percent and the overnight hotel rates down to 56.6 percent. Likewise, the cold war drives up the unemployment rate, especially in the hospitality sector.
The Lebanese financial market appears to be intact although Saudi Arabia is heavily involved in the Lebanese touristic sector. In fact, the unidirectional causality between FSI and ECO shows that, in order to cause an economic recession, Saudi Arabia GPR must first trigger the Lebanese financial market (ECO does not Granger cause FSI).

Impulse Response Functions and Variance Decomposition
The VAR impulse response functions (IRFs) reflect the direction and the magnitude of the linkages between variables along the next twelve months. Figure 3 exposes the Cholesky IRFs of FXFXD and ECO to one standard deviation shocks of FSI on the adjustment path of the variables (FSI is first-order orthogonalized using Cholesky decomposition). Similarly, FSI and FXFXD responsiveness to one standard deviation shocks of GPRs are presented in Figure 4. Recall that the ECO and FXFXD signs are inverted, so positive fluctuations indicate economic recession and FX depletion. Multiple IRFs represented in Figure A1 show that the variables are in the 95 percent confidence interval. Figure 3 shows a slight decrease in output during the first two months followed by a shock increase between period 2 and period 4. The shock decline of output starts after four months and then converges to the zero level eight months after the FSI shock. Figure 4 shows an asymmetric shock amplitude between FSI and FXFXD despite their bidirectional Granger causality. Indeed, the FSI's response to one standard deviation shock of FXFXD is obvious and reaches 3 between periods 3 and 4 while the opposite case (FXFXD response to FSI shock) has about a ten times smoother effect. Interestingly, FSI turns negative after the first two months and then jumps. In fact, FSI shock is somehow absorbed for the firsts few months by depleting gradually central bank's FX before having recourse to financial operations that aim to borrow foreign currencies. Both FSI and FXFXD responsiveness last around eight to ten months.
Similarly, FSI responsiveness to Israel GPR shock is obviously observed. It lasts more than six months. FSI shock needs about ten to eleven months to converge to the zero level.
The variance decomposition of endogenous variables is represented graphically in Figure  5 and reported numerically in Tables A1 and A2. They examine how important each of the shocks are as components of the overall (unpredictable) variance of each of the variables over time. Shock to ECO accounts for about 93% of the fluctuation in ECO, which reveals an own shock. FSI accounts for 2 percent of ECO fluctuation in the first two months and reaches 5.5 percent in the next months. The variance decompositions of FSI show that more than 92 percent of FSI shocks are explained by FSI itself in the first 2 months. Other variables such as Israel GPR and FXFXD become gradually more influenced starting at times 4 and 5. They contribute to about 5 to 7 percent of FSI fluctuation. Similarly, in the first two months, FXFXD reflects own shock since it accounts for more than 95 percent of its fluctuation. However, with time, FSI contribution to FXFXD fluctuation increases gradually to 14 percent one year after the initial impulse while own shock contribution drops to 81 percent.

Conclusions
Over the years, Hezbollah's role evolved from being hosted by Lebanon to taking Lebanon hostage (Schmitt 2007) at the behest of the Iran's ideology (DeVore 2012; Seliktar and Rezaei 2020). Hezbollah's activities that are mostly illegal have harmful consequences on the Lebanese economy. Moreover, it takes sovereign decisions as well as risky actions in the region, mainly against Israel (for resistance ideology raison d'être) and Saudi Arabia (for ideological and geopolitical rivalry), and then forces Lebanon to pay the consequences (Grumet 2015). Geopolitical consequences of Hezbollah's domination have been extensively studied and analyzed in politics, sociology, and geopolitics. However, empirical economic studies remain rare, if not inexistent. They are rather descriptive and informative economic news, published in newspapers and press releases. Economic reports elaborated by the United Nations, Reuters, the World Bank, or other international organizations are limited to estimating the cost of reconstruction (after a war) or to exposing in value the costs or the losses on welfare, agriculture, and employment.
The present paper aims to analyze empirically the impact of regional geopolitical tensions with Hezbollah on the Lebanese financial market and economic activity (ECO).
It first proceeds with graphical analysis of the Lebanese financial market that is measured with the Financial Stress Index (FSI), on a monthly basis from 1998 to January 2018 (Ishrakieh et al. 2020a(Ishrakieh et al. , 2020b. In this study, the FSI was updated to November 2018 and its analysis started from June 2006 after complete Israeli deliberation from Lebanese territories. Graphical analysis presumes that local economic and political trouble, although numerous, do not seem to generate high FSI spikes whereas high FSI spikes seem to be associated with regional geopolitical tensions where Hezbollah is in the details. Similarly, it appears that most of the recession periods overlap positive, high FSI spikes. Nevertheless, empirical tests are crucial to verify the preliminary deductions. Then, based on Granger causality tests under VAR models followed by the Cholesky impulse-response functions and variance decomposition of variables, this paper examines the dynamic relation and interaction between Israeli and Saudi Arabian geopolitical risks (toward Hezbollah), with the Lebanese financial market and economic activity. The financial stress index is the most common variable used in the literature to test under VAR models its dynamic relationship with the economic activity (Calvo and Talvi 2005;Claessens et al. 2010;Reinhart and Rogoff 2009;Davig and Hakkio 2010;Cevik et al. 2016) or with geopolitical risks along with other economic variables (Çamlıca 2016;Das et al. 2019;Mansour-Ichrakieh and Zeaiter 2019;Saint Akadiri et al. 2020).
The GPR index of Saudi Arabia and Israel were taken from Caldara and Iacoviello (2018), calculated on a monthly basis from January 1985 to September 2018 (GPR data were lately updated to October 2020).
The innovative character of this paper is also in the choice of the adequate level of foreign reserves (FX) that best fits a dollarized country (Gonçalves 2008): The central bank's foreign reserves to total deposit in foreign currencies (denoted FXFXD).
This study aimed to achieve to one of two possible conclusions: If the Lebanese financial market shows independency or low dependency-causality to the regional geopolitical risks, then Hezbollah geopolitical tensions with Israel and Saudi Arabia do not seem to negatively affect the Lebanese financial stability. In consequence, economic reforms, monetary and fiscal policies can be improved independently from the geopolitical, international, and diplomatic arrangements.
If the Lebanese financial market shows significant dependency-causality to the regional geopolitical risks, then Hezbollah's tensions with Israel and Saudi Arabia trigger Lebanese financial stability and economic activity. Therefore, instead of solving the economic crisis from a purely economic perspective, measures towards negotiation and conflict resolution with the neighborhood are needed, which require de-Hezbollizing Lebanon.
The results reveal a significant unidirectional relation from FSI to ECO (p-value 0.004), which means that, in Lebanon, a financial stress seems to be followed by an economic recession within two months while the economic activity does not seem to be strong enough to "Granger cause" a financial market instability.
Empirical outcomes also expose a bidirectional relation between FXFXD and FSI that is highly significant when the VAR model includes GPRs (with p-value = 0.00) and barely significant internally (p-value = 0.08). The FXFXD-FSI bidirectional relationship indicates that, when uncertainty (especially resulting from geopolitical tensions) is expressed in the financial market (FSI), economic agents look after converting local currency to foreign ones (FXFXD). Consequently, the depletion of FX arises and then "Granger causes" a more severe financial crisis (FSI) that may ends in an economic contraction (as verified by the unidirectional relation from FSI and ECO). The deduction seems aligned with the IMF-2017 country report analysis for Lebanon where Ahuja et al. (2017) stated: "A common shock to bank liquidity, that leads to a demand for foreign currency, could result in a drop in international reserves (1 percent of deposits are equivalent to 3.7 percent of reserves)".
The findings indicate that Israel and Saudi Arabia geopolitical risks affect the Lebanese financial market differently. While Israel geopolitical risks appear to be a good predictor for the Lebanese financial crisis within six months, Saudi Arabia GPR does not. This means that the Lebanese financial market remains intact although its heavy involvement in the Lebanese economy that is mainly conducted through the labor market and the touristic sector. In fact, based on the FSI and ECO unidirectional causality, the Lebanese financial market must first be affected in order to hit the economic activity. In other words, even if the GRP of Saudi Arabia triggers the Lebanese economy, the financial market will not be affected. Undoubtedly, a more pointed dynamic relation between Saudi Arabia GPR and the Lebanese economic sectors or, more precisely, the touristic sector will be more informative. Likewise, Hamadeh and Bassil (2017) verified the impact of geopolitics, or more precisely terrorism, on the Lebanese touristic sector. Moreover, they found that Arab tourists are significantly more affected than the European ones.
Although Saudi Arabia's geopolitical risks toward Hezbollah (in Lebanon) are not powerful enough to destabilize the Lebanese financial market, it is found to be a threat for Turkey. Mansour-Ichrakieh and Zeaiter (2019) proceeded with a similar empirical analysis between Saudi Arabia GPR and the Turkish financial market and found that Saudi Arabia GPR does not only trigger a severe financial crisis in Turkey, but it also changes its state (threshold VAR) from a low stress level to a high stress level. The findings raise the question of whether Saudi Arabia considers Turkey more dangerous than Hezbollah.
Finally, this study exhibits the existence of a unidirectional causality between Israel GPR and the Lebanese financial market and sheds light on its deleterious effect. In fact, based on the previous bidirectional causality between FSI and FXFXD and the dynamic relation between FSI and ECO, this paper concludes that, when Israel and Hezbollah play geopolitics, the Lebanese financial market seems to respond obviously, by gradually depleting the central bank's foreign reserves. The latter in return predicts further destabilization of the Lebanese financial market before hitting the economic activity.
The findings do not specify whether the threats are generated from Israel or from Hezbollah unless a Hezbollah GPR index is constructed and then VAR models and Granger causality tests are run.
Regardless of who acts and who reacts (Hezbollah or Israel), the perpetual tit-for-tat between them drives Lebanon and its economy the main victims. For instance, in July 2006, after Hezbollah captured Israeli soldiers, Israel responded severely and attacked Hezbollah inside of Lebanon (Sharp et al. 2006). Although "Israel did not attack the government of Lebanon, but rather Hizbullah military assets within Lebanon" (Schmitt 2007), Lebanon's cities and infrastructures underwent destruction as well as more than 900,000 Lebanese civilians or about 1 4 of the total population became displaced (Internal Displacement Monitoring Center 2010).
Geopolitical tension is not necessarily expressed by military or terrorist attacks, but it is also through several media channels. Media campaigns raise geopolitical risks especially when the speakers are engaged in military or terrorist acts and want visibility in the media following their actions (Tsesis 2017). Hezbollah's leader is so talented in public speaking that his speeches are extensively studied in the literature. Many researchers have been breaking down, analyzing, interpreting, and even revealing hidden messages.
Israel geopolitical risks overshoot the Lebanese financial instability through depleting central bank's foreign reserves and then end up weakening the economic activity.
Since Israeli geopolitical risks cause deleterious effect on the Lebanese financial stability, the author concludes that, in order to enhance a future financial stability and to promote economic growth, political-geopolitical measures toward negotiation and conflict resolution with the neighborhood (against Hezbollah ideology) are needed, which require first de-Hezbollizing Lebanon. Future studies in law, political science, and geopolitics are expected in order to verify how "realistic" is it to "de-Hezbollize" Lebanon.
