Summary of the Technical Note on Brazil's Systemic Liquidity Management

Core Content

This technical note from the International Monetary Fund (IMF) provides an assessment of Brazil's financial sector, with a specific focus on systemic liquidity management. It outlines the structure of key liquidity markets, the role of central bank and government authorities in liquidity provision, and key issues affecting financial stability. The analysis is based on data and observations from the 2018 FSAP mission.

Main Points

1. Structure of Key Liquidity Markets

• Money and Fixed Income Markets:

  • Brazil's money market is dominated by overnight instruments, with the SELIC repo market being the deepest and most actively traded segment.
  • Government bonds are the main component of the fixed income market, with most instruments indexed to either the SELIC or CDI rates.
  • The CDI rate is less representative of actual interbank funding costs and is often calculated using a fallback rule based on SELIC.

• Foreign Exchange Market:

  • Brazil's FX market is among the top 20 globally but smaller than advanced economies.
  • The FX spot market is limited due to regulatory constraints, with only 189 authorized banks allowed to engage in FX settlements.
  • FX derivatives, particularly USD futures, are more liquid and serve as the primary tool for hedging and price discovery.

2. Authorities' Approach to Liquidity Management

• BCB's Operational Framework:

  • The BCB uses the SELIC rate as its monetary policy target and conducts open market operations (OMOs) to manage liquidity.
  • It maintains a liquidity surplus of around 20% of GDP and relies on high reserve requirements and repo operations to sterilize excess liquidity.

• Foreign Exchange Intervention:

  • The BCB frequently intervenes in FX futures markets to provide hedges when alternatives are limited.
  • The FX derivatives market is the main hub for price discovery and liquidity management.

• Government Bond Market Support:

  • The BCB and MOF actively manage government bond market liquidity, especially during volatile periods.
  • The MOF uses reverse auctions to inject liquidity into the bond market.

3. Key Issues for Financial Stability

• Reliance on Central Authorities:

  • Market participants heavily depend on the BCB and MOF for liquidity support, which may reduce incentives for self-sufficiency in risk management.

• FX Spot Market Development:

  • The FX spot market is underdeveloped compared to other emerging markets, limiting direct FX liquidity for many participants.
  • Regulatory restrictions on FX access hinder market depth and liquidity.

• Representativeness of Money Market Benchmarks:

  • The CDI benchmark is not representative of actual interbank funding costs, as it is based on a small subset of transactions.
  • Replacing CDI with SELIC is recommended to improve benchmark accuracy and market resilience.

• Market Maker of Last Resort:

  • The BCB acts as a market maker of last resort, providing liquidity through OMOs and maintaining FX reserves to support market stability.

4. Recommendations

Key Information

• Liquidity Surplus: Brazil has a significant structural liquidity surplus (around 20% of GDP), supported by large FX reserves.
• CDI vs SELIC: The CDI benchmark is less liquid and not representative of actual funding costs, while SELIC is a more accurate and actively traded rate.
• Derivatives Markets: Interest rate and FX derivatives are well-developed, with CDI-based instruments being more prevalent. FX derivatives are more accessible and liquid than the spot market.
• Regulatory Constraints: FX spot market development is hindered by capital controls and restrictions on domestic participants.
• BCB's Role: The BCB plays a central role in liquidity management through OMOs, FX interventions, and securities lending.
• Coordination: Close coordination between the BCB and MOF is essential during liquidity stress periods.

Conclusion

Brazil's financial markets are generally liquid and sophisticated, with strong infrastructure and a preference for short-term, high-quality instruments. However, there are key challenges related to the representativeness of money market benchmarks and the limited development of the FX spot market. The BCB's role in liquidity management is crucial, but its reliance on government bonds and FX reserves highlights the need for structural reforms and regulatory updates to enhance market resilience and reduce dependency on central bank support.
