Summary of C: Initial Considerations Regarding a Macro-Prudential Instrument Based on the Net Stable Funding Ratio (NSFR)

Core Content

The document explores the potential use of the Net Stable Funding Ratio (NSFR) as a macro-prudential instrument, building on the lessons learned from the financial crisis and the existing micro-prudential standards. It emphasizes the importance of liquidity and capital regulation in enhancing the resilience of the banking system and the need for systemic risk mitigation through coordinated regulatory measures.

The NSFR, as a structural liquidity risk metric, is designed to reduce maturity mismatches between assets and liabilities over a one-year horizon. It complements the Liquidity Coverage Ratio (LCR) by focusing on long-term liquidity risk and encouraging a stable funding profile. The NSFR is not yet fully implemented, and further monitoring and analysis are required before considering its use as a macro-prudential tool.

Main Views

• Macro-prudential framework: The financial crisis underscored the need for macro-prudential tools alongside micro-prudential ones to ensure systemic resilience.
• NSFR as a complement: The NSFR can be used in conjunction with the counter-cyclical capital buffer (CCB) to address systemic liquidity risks.
• NSFR as a standalone tool: There is potential to use the NSFR as a standalone macro-prudential instrument, especially to address procyclical risk-taking and systemic liquidity stress.
• Interaction between capital and liquidity: There is a positive relationship between capital ratios and NSFR. Increasing capital can improve NSFR, and vice versa. However, they are not perfect substitutes, and synergies exist in their implementation.
• Counter-cyclical behavior of liquidity: Liquidity tends to be low during booms and high during downturns, which can lead to excessive credit growth and worsen economic downturns. This behavior could be counter-cyclical and thus systemically harmful.
• Need for adjustment: The NSFR, being a static metric, may not fully capture dynamic liquidity risks. Therefore, adjusting its factors (both for assets and liabilities) could be necessary to better reflect systemic conditions.

Key Information

• NSFR objective: To ensure banks have a stable funding profile by limiting reliance on short-term funding relative to the liquidity risk of their assets.
• NSFR components:
  • Available Stable Funding (ASF): Reflects the liquidity and stability of liabilities.
  • Required Stable Funding (RSF): Reflects the liquidity risk of assets.
• NSFR implementation: The final calibration of the NSFR was published in October 2014, with implementation expected in 2018.
• Potential NSFR modifications:
  • Adjusting RSF factors: For specific asset classes, sectors, or funding sources to reflect systemic risks.
  • Adjusting ASF factors: To reflect the stability of funding sources, especially in low-yield environments.
• Trigger mechanisms: A mechanism to signal when to increase the NSFR or adjust its factors is necessary for its macro-prudential use.
• Cyclical behavior of NSFR:
  • NSFR levels tend to be low during booms and high during stress periods.
  • This could be counter-cyclical, reinforcing systemic stress during downturns.
• Current NSFR performance:
  • EU banks have shown improvement in NSFR levels since 2011, with weighted averages above 100% in December 2013.
  • However, the magnitude of cyclical behavior in NSFR is still uncertain and needs further analysis.

Considerations for Macro-Prudential Use

• The NSFR, in its current form, is micro-prudential but can be modified to serve macro-prudential purposes.
• A counter-cyclical NSFR could be implemented by:
  • Raising the minimum threshold under certain conditions.
  • Adjusting RSF and ASF factors to reflect systemic liquidity risks.
• Systemic risk sources include:
  • Excessive credit growth and leverage.
  • Excessive maturity mismatch and market illiquidity.
  • Exposure concentrations.
  • Misaligned incentives leading to moral hazard.
• Challenges:
  • The static nature of NSFR may not fully capture dynamic liquidity risks.
  • Coordination and harmonization across jurisdictions are necessary to ensure comparability and legal certainty.
  • Fire sales and procyclical behavior of liquidity could exacerbate systemic stress and may require additional macro-prudential tools.

Conclusion

The NSFR has the potential to be a valuable macro-prudential tool, especially in addressing systemic liquidity risks. However, its current design and implementation require further monitoring and analysis. A counter-cyclical NSFR could be introduced through adjustments in factors or trigger mechanisms, but care must be taken to avoid unintended consequences. The interactions between capital and liquidity standards should be considered in the context of financial stability and systemic risk mitigation.
