Summary of the Republic of Poland: Technical Note on Stress Testing the Banking Sector (July 2013)

Core Content

This document provides an overview of the stress testing framework applied to the Polish banking sector during the 2013 Financial Sector Assessment Program (FSAP) Update. The tests were conducted by the National Bank of Poland (NBP) and the FSAP team, assessing the resilience of the banking system under various macroeconomic and financial stress scenarios.

Main Points

1. Banking System Overview

• The Polish banking system is dominated by foreign-owned banks, accounting for about two-thirds of the total assets.
• The largest bank is a domestic bank partially owned by the state.
• The system is not highly concentrated, with the top 5 banks holding about 44% of total assets.
• The system is well-capitalized and liquid, with high-quality capital.
• The capital adequacy ratios (CARs) of most banks are above regulatory minimums, even under severe stress scenarios.

2. Stress Testing Objectives

• To evaluate the resilience of the banking system to adverse macroeconomic scenarios.
• To identify vulnerabilities and guide supervisory policy and risk management practices.

3. Types of Stress Tests Conducted

• Top-Down Solvency Stress Tests: Conducted by NBP and FSAP team, covering 20 major banks (representing 85% of total assets).
• Top-Down Market-Based Stress Tests: Conducted by FSAP team, using equity prices and Moody's analytics to estimate default risk.
• Bottom-Up Stress Tests: Conducted annually by the Financial Supervision Authority (KNF), but not specifically for the 2013 FSAP Update.
• Liquidity Stress Tests: Conducted by NBP, assessing the system's ability to withstand liquidity shocks.

4. Stress Test Scenarios

• Baseline Scenario: Consistent with IMF projections, representing normal economic conditions.
• Recession Scenarios:
  • V-shape: Sharp decline in GDP growth followed by a rebound.
  • U-shape: Two consecutive years of negative growth.
  • L-shape: Prolonged period of negative growth.

The scenarios assume GDP growth rates significantly below the historical average, with rising unemployment and inflation, and depreciation of the zloty.

5. Capital Requirements

• Capital requirements were based on Basel III implementation timelines.
• Minimum CAR requirements for the years 2013–2017 were:
  • 8% (2013–2015)
  • 8.625% (2016)
  • 9.25% (2017)
• Tier 1 capital requirements were:
  • 4.5% (2013)
  • 5.5% (2014)
  • 6% (2015)
  • 6.625% (2016)
  • 7.25% (2017)

6. Key Findings

• Solvency Stress Tests:

  • Only small banks (representing up to 30% of assets) may struggle to meet capital requirements under recession scenarios.
  • The most severe scenario, the L-shape recession, could lead to total capital needs of PLN 10.5 billion, equivalent to less than 1% of total assets.
  • The capital conservation buffer becomes relevant in 2016 and 2017, adding to the capital requirements.

• Liquidity Stress Tests:

  • The system is resilient to large liquidity shocks.
  • Some small banks (representing 10% of assets) may face difficulties in meeting liquidity needs.
  • Forced sales of liquid assets could affect the secondary market for government bills and bonds.

• Interconnectedness Risk:

  • Limited contagion risk in the system.
  • No specific contagion tests were conducted, but NBP shared results from its domino-effect simulation.
  • Only three commercial banks could trigger second-round defaults, with the affected banks representing less than 2% of total assets.

• Market-Based Stress Tests:

  • Suggested that some smaller banks could experience substantial declines in their capital-asset ratios.
  • The default of a few institutions cannot be ruled out under adverse scenarios.
  • However, the high capital adequacy ratios suggest that even with large declines, the system remains above regulatory minimums.

• Sensitivity Tests:

  • Conducted by NBP to evaluate the impact of isolated shocks on capital and liquidity.
  • Counterparty risk shocks were the most severe, with banks breaching minimum capital requirements representing about 14% of total assets.

7. Recommendations

• Enhance coordination between the KNF's bottom-up stress tests and the NBP's top-down stress tests.
• Improve the sharing of information between the two authorities.
• Priority: Low
• Time Frame: Medium

Key Information

• The stress tests were based on data from 2012 and forward.
• The FSAP team used representative banks due to data confidentiality constraints.
• The results of the top-down tests were consistent with the bottom-up results from 2012, despite different scenarios and time horizons.
• The capital adequacy ratio (CAR) is a key indicator used throughout the stress testing process.
• The tests revealed that while the overall banking system is resilient, small banks may be more vulnerable.

Conclusion

The Polish banking system is well-capitalized and liquid, with the ability to withstand large macroeconomic shocks. However, small banks may require additional capital buffers to ensure resilience under adverse conditions. Greater integration of top-down and bottom-up stress testing approaches would enhance the effectiveness of banking system surveillance and inform better supervisory policies.
