Summary of Policy Brief: How to Solve the Greek Debt Problem

Core Content

This Policy Brief, authored by a group of economic experts, addresses the issue of Greece's unsustainable debt levels and evaluates the effectiveness of the Eurogroup's proposed debt relief measures. It argues that the current measures are insufficient to ensure long-term debt sustainability and proposes alternative approaches that align with EU law.

Key Findings

• Greece's Debt Situation: Greece's public debt is around €330 billion, or 180% of GDP. Over 70% is owed to European official creditors, and the country has been largely excluded from private capital markets for the past eight years.
• Debt Sustainability: Debt sustainability is defined as maintaining a stable or declining debt-to-GDP ratio. It also considers gross financing needs, which is the amount a country must borrow annually to service its debt.
• Eurogroup's Proposed Measures: The Eurogroup has outlined measures such as maturity extensions and interest deferrals for EFSF and IMF loans, with repayment using ESM funds. These measures do not include face value reductions or interest rate cuts.
• Shortcomings of Eurogroup Measures: Even with full implementation of these measures, Greece's debt remains unsustainable due to the shift to higher-cost private borrowing after 2018. The required primary surplus to maintain sustainability is too high and unrealistic to be sustained for the long term.
• Need for Additional Debt Relief: The Brief concludes that conditional face value debt relief is necessary to achieve sustainability, and that such relief could be as low as 10–15% of the outstanding official debt if it encourages further fiscal adjustment.

Main Arguments

1. Why the Eurogroup Measures Are Insufficient

• The Eurogroup's measures, while reducing some debt service obligations, do not address the growing burden of private sector debt.
• Under the Eurogroup's assumptions, gross financing needs would still exceed 20% of GDP by 2047, leading to an unsustainable debt-to-GDP ratio.
• The required fiscal surplus (above 2% of GDP) is historically implausible and may not be achievable over the long term.

2. Why Not Wait and See?

• A "wait-and-see" approach, delaying the decision on additional debt relief, could risk a self-fulfilling debt crisis.
• If Greece returns to private capital markets before its debt is sustainable, it could face high borrowing costs, leading to a rapid accumulation of debt.
• The Eurogroup's measures may delay the crisis but not prevent it, especially if Greece's fiscal performance does not meet expectations.

3. Broadening the Base of Debt Relief

• One alternative is to extend debt relief measures to other official loans, such as those from the Greek Loan Facility (GLF).
• This would include amortization deferrals, interest deferrals, and zero lending spreads.
• Even with these measures, gross financing needs would still rise above 20% of GDP, and the debt-to-GDP ratio would eventually increase again.

4. Conditional Face Value Debt Relief

• A second alternative is to provide face value debt relief on EFSF loans, structured in a way that is consistent with EU law (Article 125 of the Lisbon Treaty).
• This would require Greece to meet ambitious fiscal targets beyond 2022 to justify the relief.
• The relief could be modest (10–15% of official debt) if it incentivizes further fiscal adjustment.

Conclusion

• The Eurogroup's measures alone are not sufficient to ensure Greece's long-term debt sustainability.
• A two-stage approach—combining the Eurogroup's measures with conditional face value debt relief—could be a viable path forward.
• This approach would avoid moral hazard and comply with EU law, as long as it is tied to fiscal discipline and sustainable growth.
• However, it would require significant official financing over a long period, which may be politically and economically challenging.
