1. Introduction
1.1. Background
External debt is a critical component of economic policy in developing countries, enabling governments to finance development projects, bridge fiscal deficits, and address balance-of-payments challenges. However, the mismanagement of external debt can exacerbate economic vulnerabilities, leading to currency depreciation, liquidity crises, and reduced fiscal space for essential services (
Reinhart & Rogoff, 2009). In Egypt, external debt has surged from USD 55.8 billion in 2015 to USD 165.3 billion in 2023, according to the Central Bank of Egypt (
Central Bank of Egypt, 2023). Despite the debt-to-GDP ratio remaining at approximately 45%—below the 60% threshold considered risky for developing economies (
International Monetary Fund, 2020)—Egypt grapples with a severe economic crisis. This crisis manifests as a persistent shortage of foreign exchange, sharp depreciation of the Egyptian pound (losing over 60% of its value against the USD between 2020 and 2024), and increasing debt-servicing costs (
International Monetary Fund, 2024a).
A significant portion of Egypt’s external loans have been allocated to infrastructure and public service projects, such as the New Administrative Capital, road networks, and power plants. While these projects are vital for long-term development, they typically yield economic returns over extended periods, often spanning decades. Meanwhile, a considerable share of Egypt’s debt portfolio includes short- and medium-term loans, which require repayment before these projects generate sufficient revenue. This misalignment between debt maturities and project returns has placed immense pressure on Egypt’s foreign exchange reserves, exacerbating liquidity constraints and contributing to currency depreciation. This paper argues that Egypt’s economic challenges stem not from the volume of external debt but from inadequate debt management strategies, particularly the failure to align loan repayment schedules with the economic returns of financed projects.
1.2. Research Problem
The paradox at the heart of Egypt’s external debt crisis lies in the coexistence of a manageable debt-to-GDP ratio with severe economic distress, including foreign exchange shortages and currency depreciation. While the volume of debt remains within internationally accepted limits, the allocation of loans to long-term, non-revenue-generating projects, coupled with reliance on short-term debt, has created liquidity pressures that undermine economic stability. The absence of a strategic debt management framework that aligns debt maturities with project returns has exacerbated these challenges, diverting scarce foreign exchange resources to debt servicing rather than productive investments. This study seeks to investigate whether Egypt’s crisis is primarily a debt management issue rather than a debt volume problem, focusing on the role of short- and long-term debt in shaping economic outcomes. This study defines Egypt’s situation not as a traditional debt crisis, but as a debt management crisis characterized by a liquidity and currency crisis. This is evidenced by a persistent shortage of foreign exchange, a sharp depreciation of the Egyptian pound, and increasing debt-servicing costs, all occurring despite a manageable debt-to-GDP ratio.
This study’s primary contribution to the existing literature on Egypt’s macroeconomic challenges is twofold. First, it offers a novel analytical framework by redefining the situation as a debt management crisis, shifting the focus from the quantity of debt to its maturity structure and its alignment with economic returns. Second, it provides new empirical evidence by applying Granger causality tests to show that short-term external debt has a statistically significant and predictive causal relationship with the exchange rate. This finding isolates a key mechanism through which liquidity pressures translate into currency depreciation and provides a more nuanced, empirically supported explanation for the recurring currency instability.
1.3. Research Questions
This working paper addresses the following questions:
To what extent do Egypt’s external debt management practices contribute to the current economic crisis, particularly in terms of foreign exchange shortages and currency depreciation?
How does the allocation of external loans to long-term infrastructure projects with delayed returns affect Egypt’s liquidity and debt sustainability?
What role does the composition of short- and long-term debt play in exacerbating Egypt’s economic challenges?
How can strategic debt management, including aligning debt maturities with project returns, mitigate Egypt’s external debt crisis?
1.4. Significance of Study
This study contributes to the academic and policy discourse on external debt in developing economies by reframing Egypt’s crisis as a debt management challenge rather than a debt volume issue. By analyzing the interplay between debt maturities, project returns, and economic outcomes, the paper provides a nuanced understanding of the structural factors driving Egypt’s economic difficulties. It fills a gap in the literature, which often focuses on aggregate debt levels without examining the strategic allocation of loans or the temporal dynamics of debt repayment. For policymakers, this study offers actionable recommendations to enhance debt sustainability, optimize resource allocation, and reduce economic vulnerabilities. The findings are relevant not only to Egypt but also to other middle-income countries facing similar debt management challenges.

2. Theoretical Background & Literature Review
2.1. Theoretical Foundations of External Debt and Crisis
The theoretical literature on external debt provides a robust framework for understanding the mechanisms through which borrowing can lead to economic instability. Three key theories are particularly relevant to Egypt’s case.
The dual-gap model (
Chenery & Strout, 1966) argues that developing countries require external borrowing to bridge savings and foreign exchange gaps, enabling investment and growth. Egypt’s reliance on external loans to finance infrastructure aligns with this framework, but the theory does not address the risks of mismanaging debt maturities or allocating loans to projects with delayed returns.
This vulnerability is compounded by the debt overhang theory (
Krugman, 1988), which posits that high levels of debt discourage private investment due to expectations of future tax increases or default risks, thereby stifling economic growth. In Egypt’s case, the accumulation of external debt may reduce investor confidence, contributing to foreign exchange shortages and currency depreciation. However, this theory alone does not fully explain Egypt’s crisis, as the debt-to-GDP ratio remains moderate, suggesting that management issues are a more significant factor.
Furthermore, the concept of public debt management theory emphasizes the importance of strategic debt management to minimize costs, risks, and economic disruptions while achieving development goals (
Wheeler, 2003). Effective debt management involves optimizing the debt portfolio’s maturity structure, balancing short- and long-term debt, and aligning repayment schedules with economic returns. In Egypt, the lack of such a strategy—particularly the use of short-term debt for long-term projects—has amplified liquidity pressures (
Abbas et al., 2010).
Although these models are relevant to the Egyptian case, they are not the only ones that have dealt with external debt and its impact on economic performance. There are several models that have dealt with external debt, such as the financial cycle theory which links external debt accumulation to global capital flow cycles, where surges in borrowing during economic booms lead to crises during downturns (
Borio, 2014). Egypt’s increased borrowing during periods of high global liquidity, followed by repayment challenges during economic slowdowns, reflects this dynamic.
Also, resource allocation theory suggests that the effectiveness of external debt depends on its allocation to productive investments (
Cohen, 1993). In Egypt, the heavy allocation of loans to infrastructure projects with long gestation periods, without sufficient short-term revenue sources, has constrained fiscal space and exacerbated economic vulnerabilities.
A notable challenge faced by many emerging economies, including Egypt, is known as “Original Sin” (
Eichengreen & Hausmann, 1999). This refers to the inability of a country to borrow externally in its own currency. As a result, Egypt’s external debt is overwhelmingly denominated in foreign currencies, primarily the U.S. dollar. This structural feature exposes the country to significant exchange rate risk. When the Egyptian pound depreciates, the cost of servicing foreign currency-denominated debt increases, creating a vicious cycle where currency volatility exacerbates the debt burden. This theoretical concept directly underpins our empirical analysis, which investigates the causal link between short-term foreign debt and exchange rate depreciation.
2.2. Strategies for Managing Foreign Debt
Effective foreign debt management requires strategies that balance economic growth, fiscal sustainability, and liquidity needs. Key strategies include the following:
2.2.1. Debt Portfolio Optimization
Governments should diversify their debt portfolio by balancing short- and long-term debt to reduce refinancing risks. Long-term debt is preferable for financing infrastructure projects with extended return periods, while short-term debt should be limited to immediate liquidity needs (
Togo, 2007). In Egypt, the high share of short-term debt (approximately 20% of total external debt in 2023) has increased repayment pressures (
Central Bank of Egypt, 2023).
2.2.2. Maturity Alignment
Aligning debt maturities with project returns is critical to ensuring debt sustainability. For instance, loans financing infrastructure projects should have repayment schedules that match the projects’ revenue generation timelines, reducing the need for premature debt rollovers (
Wheeler, 2003). Egypt’s failure to adopt this approach has led to liquidity constraints, as seen in the case of the New Administrative Capital.
2.2.3. Cost–Risk Analysis
Debt management strategies should incorporate cost–risk analyses to evaluate the trade-offs between borrowing costs and repayment risks. This includes assessing interest rates, currency risks, and refinancing needs (
Cassard & Folkerts-Landau, 2000). Egypt’s reliance on variable-rate loans has exposed it to interest rate volatility, exacerbating debt-servicing costs.
2.2.4. Alternative Financing Mechanisms
To reduce dependence on traditional loans, governments can explore alternative financing, such as public–private partnerships (PPPs), green bonds, or diaspora bonds (
Ketkar & Ratha, 2009). These mechanisms can provide long-term funding with lower repayment pressures, offering a potential solution for Egypt.
2.2.5. Debt Restructuring and Negotiation
In cases of liquidity crises, debt restructuring or negotiations with creditors can extend maturities or reduce interest rates, easing repayment burdens (
Reinhart & Rogoff, 2009). Egypt’s engagements with the IMF and bilateral creditors highlight the importance of such strategies.
2.3. Country-Specific Case Studies
Several studies have explored foreign debt management, offering insights relevant to Egypt’s context:
Abbas et al. (
2010) examined debt management in low- and middle-income countries, finding that poor debt portfolio structures—particularly excessive short-term debt—amplify economic vulnerabilities. The study recommends prioritizing long-term, concessional loans for infrastructure financing, a strategy applicable to Egypt (
Abbas et al., 2010).
Togo (
2007) analyzed debt management strategies in developing economies, emphasizing the importance of maturity alignment and risk diversification. The study found that countries with balanced debt portfolios are better equipped to handle external shocks, suggesting a need for Egypt to restructure its debt composition (
Togo, 2007).
Panizza (
2008) investigated the impact of debt management on economic stability, highlighting that misaligned debt maturities can lead to liquidity crises even when debt levels are sustainable. This finding resonates with Egypt’s experience, where short-term debt has driven foreign exchange shortages despite a moderate debt-to-GDP ratio (
Panizza, 2008).
Das et al. (
2012) studied debt sustainability in emerging markets, arguing that effective debt management requires integrating debt policies with fiscal and monetary frameworks. The study’s emphasis on cost–risk analysis offers a framework for evaluating Egypt’s debt strategy (
Das et al., 2012).
International Monetary Fund (
2020) provided a comprehensive analysis of debt sustainability, noting that countries with high debt-servicing costs relative to revenues face significant risks. Egypt’s increasing debt service ratio (approximately 40% of export revenues in 2023) underscores the need for improved management practices (
International Monetary Fund, 2020).
2.4. Theoretical Framework for Crisis Indicators and Variable Selection
The selection of variables for this study is grounded in the established theoretical and empirical literature on financial crises. This approach is informed by models that identify key leading indicators of a crisis, thereby providing a robust justification for the variables used in the empirical analysis.
Variable selection depends on frameworks such as Krugman’s first-generation currency crisis models, which link a managed exchange rate regime’s unsustainability to a depletion of foreign exchange reserves caused by a consistent imbalance. These models underscore the crucial role of foreign exchange reserves and the exchange rate as key variables that reflect underlying fiscal and monetary pressures. A rapid decline in reserves signals a fundamental disequilibrium that ultimately forces a devaluation (
Krugman, 1979).
Additionally, this analysis is consistent with the empirical findings of Kaminsky and Reinhart on crisis episodes, which identify a rise in short-term external debt as a key “early warning indicator” for a currency crisis. Their work demonstrates that a rapid accumulation of short-term debt can trigger a liquidity crisis, as countries struggle to roll over their obligations, putting immense pressure on foreign exchange reserves and leading to a sharp currency depreciation (
Kaminsky & Reinhart, 1999).
Building on this, this study uses the exchange rate (EGP/USD), foreign exchange reserves, and the composition of external debt (specifically short-term and long-term debt) as core variables. This allows us to empirically test the central hypothesis of the paper: that “the structure of Egypt’s debt, rather than its overall volume, is a primary driver of the currency and liquidity pressures that constitute its ongoing macroeconomic crisis.”
While the existing literature has extensively analyzed the macroeconomic drivers of Egypt’s debt and the symptoms of its crisis, there remains a notable gap in studies that specifically investigate the causal relationship between debt maturity structures and key crisis indicators like the exchange rate. This paper seeks to bridge this gap by empirically testing whether short-term debt, a key indicator of liquidity risk, has a direct causal impact on currency depreciation, a primary symptom of the crisis. By focusing on this causal channel, our study provides a new, empirically supported explanation for Egypt’s external vulnerabilities and offers actionable policy insights for more effective debt management.
4. Methodology
This study employs a quantitative time-series approach to investigate the relationship between external debt structure and macroeconomic stability in Egypt, particularly with regard to exchange rate volatility and foreign exchange reserves. The analysis is anchored in the premise that debt management practices, including the reliance on short-term versus long-term borrowing and the mismatch between debt maturity and project returns, can significantly influence macroeconomic health, even in the presence of a seemingly sustainable debt-to-GDP ratio.
To explore these dynamics, we used a Vector Autoregression (VAR) modeling framework. VAR is appropriate given our focus on capturing short-term interdependencies among variables without imposing strong theoretical restrictions. The model allows each variable to be treated as endogenous, offering insight into the system-wide effects of shocks in debt variables on the macroeconomic indicators of interest.
To address the issue of variables’ non-stationarity, all variables were transformed into first differences prior to estimation, ensuring that the VAR model is specified in terms of stationary series. Unit root tests (ADF) were re-run on the differenced variables, confirming that the transformed series are stationary at conventional significance levels (see
Table 2). Therefore, the VAR models estimated are explicitly formulated in first differences avoiding the risk of spurious regression associated with non-stationary series in levels.
Given the limited sample size (2010–2023, annual data)—which was deliberately chosen to capture the post-2011 political and economic transformation in Egypt—a Structural VAR (SVAR) framework with contemporaneous identification restrictions could not be reliably implemented due to insufficient degrees of freedom. Therefore, this study employs a reduced-form VAR in first differences, complemented by Granger causality to test predictive causality between debt variables and exchange rate changes. Specifically, we tested whether short-term debt and long-term debt Granger-cause fluctuations in the exchange rate, the variables were first differenced to ensure stationarity, and the F-statistics and p-values were computed for each causal direction. While this does not provide structural causality, it establishes predictive causality, which is suitable for short time-series data.
Also, due to the small sample size, which limits the reliability of Impulse Response Function (IRF) estimates, our analysis focuses specifically on the Granger causality test. The goal is to establish a preliminary causal link rather than to perform a comprehensive dynamic analysis of shock propagation, which would require a larger dataset to produce robust IRF results.
4.1. Data Description
The data span the period 2010 to 2023, incorporating annual observations on the following variables:
Exchange rate (EGP/USD);
Foreign exchange reserves (USD billions);
Short-term external debt (USD millions);
Long-term external debt (USD millions);
Inflation rate (%);
Current account balance (USD millions);
Other macroeconomic control variables were initially considered but excluded to preserve the degrees of freedom given the short time series (such as GDP growth rate, Gross fixed capital formation, global interest rate).
The selection of variables is not arbitrary but is directly tied to the theoretical framework outlined in
Section 2. The Exchange Rate (EGP/USD) and Foreign Exchange Reserves are included as they are classic indicators of a currency and liquidity crisis, as discussed by
Krugman (
1979) and
Kaminsky and Reinhart (
1999). The short-term and long-term external debt variables are central to the hypothesis, allowing us to empirically test the impact of debt structure on these crisis indicators. The Inflation Rate and Current Account Balance are included as control variables to provide broader macroeconomic context and to ensure the robustness of Granger causality analysis.
4.2. Stationarity Tests
Prior to model estimation, stationarity of all variables was assessed using the Augmented Dickey–Fuller (ADF) test. At level, most variables were non-stationary (i.e., contained a unit root), as expected for macroeconomic time series. The table below summarizes the ADF results at level and first difference:
ADF Test Results
Given that most variables were found to be integrated of order one (I(1)), and cointegration testing failed due to limited degrees of freedom (Johansen test could not proceed due to a non-positive definite matrix), we proceeded with a VAR model in first differences to estimate short-term relationships
4.3. VAR Model Specification
Two separate VAR models were estimated using first-differenced variables:
Model 1: Exchange Rate VAR
The dependent variable is Δ Exchange Rate, and the regressors are Δ Short-term Debt, Δ Long-term Debt, and Δ Inflation Rate.
Table 3 shows that short-term debt has a significant and positive short-term effect on the exchange rate, indicating that increased short-term borrowing contributes to currency depreciation. Long-term debt has a negative but statistically insignificant effect.
Model 2: Foreign Reserves VAR-Reduced
The dependent variable is Δ Foreign Reserves, and the regressors are Δ Short-term Debt, Δ Long-term Debt, and Δ Current Account Balance.
Table 4 shows that no variable is statistically significant at the 5% level in this model. Short-term debt has a positive but insignificant effect on reserves, while long-term debt and current account balance show negative signs, consistent with the idea that debt repayment obligations and external deficits pressure foreign reserves over time.
5. Results and Discussion
5.1. Exchange Rate Model (VAR Model 1)
The VAR results indicate that short-term external debt has a statistically significant and positive impact on the exchange rate, implying that increases in short-term borrowing are associated with currency depreciation. This finding is consistent with both theoretical expectations and empirical studies from emerging markets (e.g.,
Reinhart et al., 2003;
Hausmann & Panizza, 2011).
In the Egyptian context, this result is particularly salient. Over the last decade, Egypt has relied heavily on short-term borrowing, especially from Gulf countries and through international bond markets, to finance fiscal and current account deficits. However, short-term debt carries significant rollover risk, particularly in periods of heightened global financial volatility or domestic political instability. The need to repay or refinance large amounts of maturing debt puts downward pressure on the Egyptian pound as investors demand hard currency for exit or refinancing.
This depreciation is not merely a technical market adjustment—it creates a feedback loop. As the currency weakens, the cost of external debt servicing rises in local currency terms, which in turn worsens budget and reserve positions, further undermining confidence and intensifying pressure on the currency. This dynamic helps explain the repeated cycles of sharp devaluations, notably in 2016, 2022, and 2023, despite IMF-supported stabilization programs.
Long-term external debt did not exhibit a significant effect on the exchange rate in the short term, but it showed a negative (though statistically insignificant) relationship with foreign exchange reserves. This suggests that while long-term borrowing may not immediately impact currency value, it has a gradual draining effect on reserves over time, particularly when not tied to productive, export-generating investments.
This aligns with the Egyptian case, where a substantial portion of long-term loans have been directed toward large-scale infrastructure megaprojects, such as the New Administrative Capital and transportation networks. While these projects may yield long-term developmental benefits, they often lack near-term cash flows or foreign currency earnings. Consequently, the country must service these debts from other sources primarily foreign reserves, remittances, or new borrowing, leading to structural fragility.
The literature highlights this issue as a form of “debt overhang” (
Krugman, 1988), where existing debt suppresses future growth by diverting funds from investment toward repayment. Additionally, if long-term debt is not transparently reported or if disbursement efficiency is low, its macroeconomic contribution may be further muted.
5.2. Foreign Reserves Model (VAR Model 2)
The second VAR model found no statistically significant predictors of foreign reserves in the short run, though short-term debt exhibited a positive coefficient. This may reflect temporary boosts in reserves due to fresh disbursements, particularly from bilateral or IMF-supported loans. However, this is not a sustainable mechanism: reserves may be temporarily inflated by debt inflows but are quickly eroded by debt service obligations, import bills, or currency defense operations.
This observation aligns with Egypt’s recurrent foreign exchange shortages, despite maintaining official reserve buffers, the country has faced persistent restrictions on foreign exchange access for importers, highlighting the illiquidity or conditional nature of some reserve components (e.g., deposits from Gulf allies).
From a policy standpoint, the inability of short-term or long-term debt to sustainably support reserves suggests a need for structural current account improvements via exports, tourism, or FDI rather than reliance on debt-financed reserve accumulation.
5.3. Granger Causality Test
Based on
Table 5, and regarding short-term debt, the
p-value is below 0.05, so we reject the null hypothesis that short-term debt does not Granger-cause exchange rate volatility. Thus, short-term debt Granger-causes exchange rate changes, indicating that past changes in short-term debt help predict future movements in the exchange rate.
Based on the test results long-term debt does not Granger-cause exchange rate changes at conventional significance levels.
The Granger causality test results reveal that short-term debt Granger-causes exchange rate changes, indicating a robust and immediate predictive relationship. This suggests that increases in short-term debt significantly precede currency depreciation, consistent with the liquidity risk channel. In contrast, the test reveals that long-term external debt does not have a statistically significant causal relationship with changes in the exchange rate at conventional significance levels. This suggests that fluctuations in the exchange rate over the study period (2010–2023) are not primarily driven by the accumulation of long-term debt. This result may reflect the lagged nature of returns from long-term infrastructure projects, which typically do not generate immediate foreign exchange inflows. As such, their impact on currency valuation is likely diffused or delayed, aligning with the notion that misaligned maturities reduce the short-term responsiveness of debt-financed projects to external account pressures. This supports the theoretical argument that long-term debt, when not paired with timely revenue generation, contributes to structural vulnerabilities rather than short-term currency instability.
Also, the finding that short-term debt significantly Granger-causes exchange rate depreciation provides empirical evidence for the paper’s central argument: the crisis is rooted in liquidity pressures created by a mismatched debt maturity profile. This directly links the structural vulnerability to the observed currency crisis.
6. Conclusions, Policy Implications, and Future Research
This study examined Egypt’s external debt structure and its implications for macroeconomic stability, focusing on the distinction between short-term and long-term borrowing. By employing a Vector Autoregression (VAR) model alongside Granger causality tests on data from 2010 to 2023, the analysis revealed that short-term debt exerts significant pressure on the exchange rate, contributing to currency depreciation, while long-term debt—though less immediately disruptive—creates risks in terms of reserve sustainability when not aligned with productive investments. These findings affirm the relevance of the debt overhang hypothesis and the dual-gap model, highlighting the macroeconomic instability that arises from misaligned debt maturities and weak investment productivity. Overall, Egypt’s external vulnerability appears structural, rooted in debt composition and maturity mismatches rather than in overall debt volume.
The results carry important policy implications. Effective debt management should prioritize longer-term concessional borrowing, improved alignment between debt maturity and project returns, and enhanced transparency in project appraisal and debt reporting. These findings align with
Barrett and Johns (
2021), who emphasize the importance of maturity alignment and transparency in external liabilities. Diversifying financing sources through mechanisms such as public–private partnerships (PPPs), green bonds, or diaspora bonds can help mitigate liquidity pressures and reduce short-term rollover risks. Strengthening institutional capacity for debt sustainability analysis would further enhance resilience to external shocks.
This study is subject to several limitations that suggest directions for future research. The analysis is constrained by the short time span (2010–2023) and the use of annual data, which limit the ability to capture high-frequency dynamics or long-term cointegration. Future studies could extend the dataset or employ higher-frequency observations to enable more advanced econometric approaches, such as Structural VAR or VECM models, and to explore both short- and long-term relationships, including the application of Impulse Response Functions (IRFs). Further research should also integrate additional macroeconomic variables—such as global interest rates, fiscal policy, and capital flows—and combine quantitative techniques with qualitative insights into institutional and political determinants of debt management.
