Summary of "Assessing Liquidity Buffers in the Panamanian Banking Sector"

Core Content

This IMF Working Paper evaluates the resilience of the Panamanian banking sector to both short-term and long-lasting liquidity shocks. It focuses on the adequacy of liquidity buffers and the alignment of local regulatory measures with international standards such as the Basel III Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR).

The paper highlights the importance of financial stability in Panama, given its integrated and significant banking sector, which accounts for 189% of GDP in 2015. Despite this, the sector is not immune to liquidity risks, especially from the potential loss of foreign funding due to correspondent banking disruptions.

Main Points

1. Liquidity Buffers and Basel III Standards

• The Liquidity Coverage Ratio (LCR) is a key metric for assessing a bank's ability to withstand a 30-day liquidity stress scenario.
• Panama's Legal Liquidity Index (LLI), which is used to monitor liquidity, suggests the sector is highly liquid, with the LLI averaging around 60%.
• However, the LLI is not aligned with the LCR, as it includes a broader definition of liquid assets and different assumptions about funding stability.

2. Key Findings on LCR

• Approximations suggest that about half of Panamanian banks would need to adjust their liquid asset portfolios to meet the current LCR standards.
• In the most optimistic scenario, the median bank has an LCR of 72.7%, but about 25% of banks would still fail to meet the LCR requirement even under generous assumptions.
• The banking system as a whole has an asset-weighted average LCR of 108.3%, which is close to the current 70% LCR threshold, but not all banks are equally resilient.
• The LLI and LCR show a low correlation (0.3), indicating that the two measures assess liquidity in different ways and may not be directly comparable.

3. Resilience to Loss of Foreign Funding

• The paper assesses the impact of a loss of foreign funding, particularly from correspondent banks, using a liquidity stress test.
• The stress test assumes higher run-off rates for foreign funding than for domestic funding.
• Some banks would be forced to use up all their liquidity buffers, and a few would face shortfalls.
• However, banks with liquidity shortfalls tend to have strong solvency positions.

4. Methodological Differences

• The LLI includes lower-rated securities without haircuts and expected inflows within 6 months.
• The LCR uses a 30-day horizon and more stringent definitions of liquid assets, with haircuts applied based on credit ratings.
• The denominator for liquidity ratios differs significantly: LLI uses specific types of deposits, while LCR uses total assets or short-term liabilities.

5. Data Limitations and Regulatory Context

• The SBP's data is insufficient to compute the LCR directly, so the paper uses assumptions and approximations to estimate the LCR.
• Panama is the only country in the region without a lender of last resort (LOLR) or deposit insurance.
• The interbank market is segmented and does not function smoothly, especially under stress, as foreign banks tend to lend only to larger domestic banks.

6. International Context

• The LCR is a high standard, with a minimum requirement of 100% expected to take effect in 2019.
• As of 2015, most BCBS member countries had implemented the LCR, while Panama is among the 44 non-BCBS countries planning to adopt the standard but not yet publishing official domestic regulations.

Key Information

• Panama's Banking Sector:

  • 55% of banks are foreign-owned.
  • Banks rely heavily on external markets for funding and investment.
  • Historical stability is attributed to self-discipline and lack of systemic crises (except in 1988-89).

• Liquidity Risk Management:

  • The LLI is a conservative measure but does not reflect international best practices.
  • The LCR is more stringent and data-intensive, requiring detailed information on credit ratings, funding sources, and asset maturity.

• Stress Test Outcomes:

  • The stress test reveals significant vulnerabilities in the sector.
  • Some banks would need to use up all liquidity buffers in a severe liquidity shock.
  • The median bank has comfortable liquidity buffers, but 25% would still fall short.

• Run-off Rates:

  • Foreign retail funding is assumed to have a 50% run-off rate.
  • Foreign bank funding is assumed to have a 100% run-off rate.
  • Local funding is subject to a 10% run-off rate.
  • Interbank funding and bonds are assigned a 50% run-off rate.

Conclusion

• The Panamanian banking sector appears highly liquid based on the LLI, but falls short when assessed using the LCR.
• Data limitations and methodological differences between LLI and LCR create conflicting views on the sector's liquidity.
• The lack of a formal financial safety net and underdeveloped interbank market means that banks must hold sufficient liquidity buffers to withstand potential shocks.
• Improvements in data reporting and alignment with international standards are necessary to ensure resilience and transparency in liquidity management.
