Summary of Belgium: Technical Note on Stress Testing the Banking and Insurance Sectors

Core Content

This technical note provides a comprehensive analysis of the solvency and liquidity risks of the Belgian banking and insurance sectors as part of the Financial Sector Assessment Program (FSAP) Update. The study was conducted using mid-2012 data and macroeconomic scenarios, reflecting the state of the financial system in the aftermath of the global financial crisis.

The document outlines the methodology and results of both bottom-up (BU) and top-down (TD) stress tests for the banking sector, and a BU stress test for the insurance sector. It emphasizes the importance of integrating risk-based supervision with macroprudential policy and highlights the need for ongoing supervisory follow-up to address identified vulnerabilities.

Main Viewpoints

• Financial Sector Stability: The stress tests indicate that the financial sector has restored pre-crisis stability, but remains vulnerable to economic deterioration.
• Capital Buffers: While aggregate capitalization of the banking sector is well above Basel III minima, individual weaker banks may face significant capital needs under adverse scenarios.
• Earnings Capacity: Banks are under pressure due to declining investment returns, interest margins, and new capital requirements, which could limit their ability to maintain capital buffers.
• Sovereign Risk: Sovereign risk is a critical factor in both banking and insurance stress tests, with significant impacts on capital adequacy.
• Insurance Sector Vulnerability: The insurance sector, though sufficiently capitalized under current regulations, shows vulnerabilities under market-consistent valuation, especially in the context of Solvency II transition.
• Liquidity Management: Banks have improved liquidity management, but still rely heavily on market-sensitive funding sources and face challenges due to high asset encumbrance.

Key Information

Banking Sector

• Structure: The banking sector is dominated by four major groups, representing almost 75% of consolidated system assets. Foreign-owned banks account for more than half of the sector.
• Solvency Tests:
  • Two adverse macroeconomic scenarios were used: a "double-dip recession" and a "protracted slow growth scenario."
  • The BU stress test was conducted by the six largest banks, while the TD test covered all banks.
  • The stress tests used Basel III hurdle rates and were based on mid-2012 data.
• Liquidity Tests:
  • Focused on the impact of sudden, large-scale funding withdrawals.
  • Included assumptions on in- and outflows of assets and liabilities, as well as haircuts on balance sheet assets.
  • NBB's liquidity standards, including Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR), were applied.

Insurance Sector

• Structure: The insurance sector is dominated by a few conglomerates and operates under the Bancassurance model.
• Solvency Tests:
  • Assessed the impact of moderate and severe adverse scenarios on the capital adequacy of insurers.
  • Scenarios included changes in interest rates, equities, commercial spreads, sovereign spreads, life insurance mass lapse events, and nonlife catastrophes.
  • Six largest insurers participated in the stress test.
• Market-Consistent Valuation:
  • Indicates a severe undercapitalization of the sector under both scenarios.
  • Suggests that some business models may no longer be viable under the new Solvency II regime.

Policy Implications

• Supervisory Focus: The results support the supervisory focus on increasing capital buffers and implementing stringent liquidity standards.
• Systemic Risks: The sovereign-bank link has intensified, with a tight fiscal position exacerbated by crisis measures.
• Resolution Planning: Stress testing should be closely aligned with resolution and recovery planning.
• Vigilance Required: Supervisors should remain vigilant in monitoring both banks and insurers, especially as the sector transitions to more risk-based and market-consistent standards.
• Thematic Review: Authorities should use stress test results for thematic reviews of vulnerabilities and to integrate risk-based supervision into macroprudential policy.

Conclusion

The stress tests underscore the importance of addressing vulnerabilities in the banking and insurance sectors, particularly in relation to sovereign risk and liquidity management. The findings suggest that while the sector has improved its capital and liquidity positions, further efforts are needed to ensure long-term resilience and stability, especially as the regulatory landscape continues to evolve.
