Summary of "Rethinking banks’ liquidity requirements"

This report examines the interplay between banks' liquidity requirements (specifically the Liquidity Coverage Ratio, or LCR) and central bank liquidity support during periods of financial stress. Drawing lessons from the 2023 banking turmoil, which amplified the severity of bank runs through digitalisation and social media, the authors argue for a more integrated policy framework.

Key Highlights:

• Complementarity of Framework Components: The 2023 turmoil underscores that LCR (self-insurance-oriented) and central bank liquidity support are complementary but are often treated separately, leading to gaps in liquidity crisis management.
• Limitations of Current LCR: The LCR calibration assumes banks can withstand severe scenarios using high-quality liquid assets (HQLA), but actual events like the Silicon Valley Bank collapse showed excessive liquidity outflows not covered. Debates on refining LCR could ignore central bank access.
• Proposed Framework: A tiered asset eligibility system integrates central bank liquidity facilities:
  • Type 1 Assets: HQLA for moderate stress (similar to LCR).
  • Type 2 Assets: Broadened assets usable in central bank standing facilities.
  • Type 3 Assets: Further assets for extreme stress and emergency liquidity assistance (ELA).
• Pillar 2 Integration: Uses supervisory guidance (e.g., Supplementary Liquidity Ratios) to allow for flexible, bank-specific stress scenarios, incorporating factors like operational readiness and asset prepositioning.
• Operational Readiness: Emphasizes pre-positioning of non-HQLA assets to facilitate rapid access to central bank funds, while reducing stigma associated with borrowing, to ensure timely liquidity support.

Conclusion: The framework promotes a flexible, integrated approach, weakening the case for stricter LCR alone and enhancing overall financial system resilience. By leveraging central bank facilities, it supports banks in coping with liquidity stress without unduly constraining their core intermediation activities.
