Summary of Stress Testing the Banking Sector in the Euro Area

Core Content

This technical note from the International Monetary Fund (IMF) provides a detailed analysis of stress testing the banking sector in the Euro Area (EA) as part of the Financial Sector Assessment Program (FSAP). It outlines the findings and recommendations based on two severe macrofinancial scenarios, covering both solvency and liquidity risks, as well as their interactions and business model impacts. The document also includes a network analysis of financial institutions to assess systemic risk.

Main Scenarios and Findings

1. Solvency Stress Test

• Key Elements: The stress test evaluates the impact of macroeconomic shocks on bank capital and profitability, using a three-year horizon.
• Scenarios:
  • A geopolitical tensions escalation scenario.
  • A deep and widespread recession scenario.
• Outcomes:
  • The EA banking system remains broadly resilient, but significant capital depletion is observed under adverse conditions.
  • A small number of banks may breach regulatory capital requirements, while a larger portion would see erosion of prudential buffers.
  • Non-performing loans (NPLs) and credit risk increase over time, especially in the second year of the stress period.
  • Profitability declines due to reduced net interest income (NII) and fee-based revenues.
  • G-SIBs and universal banks are more vulnerable, with some approaching minimum regulatory thresholds.
  • Capital buffers and income diversification are crucial for maintaining financial stability.

2. Liquidity Stress Test

• Key Findings:
  • Banks generally meet liquidity coverage ratio (LCR) and net stable funding ratio (NSFR) requirements with wide margins.
  • USD liquidity risk is significant for some banks, with liquidity gaps observed in the first week of stress.
  • Survival horizons exceed two months for most banks, and no large bank reaches negative counterbalancing capacity (CBC) in mild outflow scenarios within the first month.
  • In severe outflow scenarios, 10% of banks may face negative CBC within one month.
  • The system-wide average LCR could decline by almost 50 percentage points due to valuation haircuts from forced sales of NBFIs.

3. Solvency-Liquidity Interactions

• Key Risks:
  • Endogenous liquidity flows, business risk, and counterparty credit risk (CCR) amplify stress impacts.
  • Liquidity outflows are linked to LCR run-off rates, with feedback loops between solvency and liquidity.
  • Losses from the solvency-liquidity nexus could reach up to 200% of the initial market shock.
  • CCR losses are substantial if banks liquidate derivative positions due to missed margin calls.
• Recommendations:
  • Develop tailored stress tests that consider the endogenous interaction between liquidity and capital erosion.
  • Enhance modeling of CCR, including from NBFIs, to improve accuracy of resilience assessments.

4. Network Analysis

• Key Insights:
  • Contagion risk through interbank exposures is low, but risks from NBFIs and market volatility need to be monitored.
  • Interbank resilience is supported by strong capital and liquidity positions.
  • Systemic risk maps highlight the interconnectedness of financial institutions and the potential for cascading defaults.

Key Recommendations

Main Views and Key Information

• The EA banking sector has shown resilience to recent shocks, supported by strong capital and liquidity positions, diversified deposit bases, and limited unrealized losses.
• However, the sector is not immune to stress, especially for large cross-border banks and G-SIBs, which face thinner capital and liquidity buffers.
• Profitability has improved post-GFC but has recently retreated due to weakening asset quality and tighter credit conditions.
• The system-wide LCR remains above 100% despite potential declines, indicating sufficient liquidity buffers for most institutions.
• Non-bank financial institutions (NBFIs), particularly investment funds, pose significant liquidity risks due to investor redemptions and collateral calls.
• Forward-looking risk management and continuous supervisory engagement are essential for financial stability.
• The ECB's broad collateral framework plays a stabilizing role in mitigating liquidity risks.
• Reverse stress and sensitivity tests are recommended to better assess the impact of plausible shock combinations on bank solvency and liquidity.

Financial System Structure (Table 2)

• Total Financial System Assets: EUR 80,694 billion in 2024, up from EUR 76,787 billion in 2023.
• Monetary Financial Institutions (MFIs): Account for 57.0% of total assets (EUR 46,030 billion).
• Significant Institutions (SIs): Represent 33.3% of total assets (EUR 26,837 billion), with 7 being G-SIBs.
• Less Significant Institutions (LSIs): 6.1% of total assets (EUR 4,948 billion).
• Third Country Branches: 8.4% of total assets (EUR 6,774 billion).
• Investment Funds: 24.4% of total assets (EUR 19,730 billion), with 90% of assets in open-ended funds.
• Insurance Corporations: 11.0% of total assets (EUR 8,845 billion), equivalent to 58.4% of GDP.
• Eurosystem Central Banks: 7.9% of total assets (EUR 6,357 billion).

Financial Soundness Indicators (Table 3)

• Capital Adequacy:
  • CET1 ratio: 15.9% in 2024 (up from 14.9% in 2019).
  • Tier 1 ratio: 17.3% in 2024.
  • Total capital ratio: 20.0% in 2024.
  • Leverage ratio (fully phased-in): 5.9% in 2024.
• Asset Quality:
  • Loans and advances: EUR 18,468 billion in 2024.
  • NPL ratio: 2.1% in 2024 (down from 3.2% in 2020).
  • Stage 1, 2, and 3 ratios have decreased over time, indicating improved asset quality.

Conclusion

The EA banking sector has demonstrated resilience to recent macrofinancial shocks, but vulnerabilities persist, particularly for large cross-border banks and G-SIBs. Stress testing highlights the importance of capital buffers, income diversification, and forward-looking risk management. While the system remains robust, the potential for significant capital and liquidity depletion under adverse conditions underscores the need for continued supervisory engagement and improved modeling of systemic risks.
