Managing Credit Spread Risk in Banking Under the Latest EBA Guidelines

In 2025, the financial sector continues to grapple with the evolving regulatory landscape around credit spread risk in the banking book (CSRBB). The European Banking Authority (EBA) has reinforced its 2023 guidelines, requiring banks to integrate CSRBB into their risk management and capital assessment frameworks. With banks holding over $6 trillion in sovereign and related securities, regulators are increasing scrutiny over liquidity reserves and credit spread risk exposure. The challenge for treasury teams now is to align with the latest supervisory expectations while maintaining sufficient liquidity buffers for operational needs.

Why CSRBB Matters More Than Ever

Banks traditionally prioritized interest rate risk in the banking book (IRRBB), but CSRBB is now a distinct regulatory focus. Recent studies show that over 90% of European banks’ CSRBB exposure stems from liquidity reserves, making it a critical factor in capital requirements. The EBA’s guidelines emphasize that CSRBB must be measured through changes in the economic value of equity (EVE) and net interest income (NII). Banks that fail to address CSRBB risk adequately may face heightened capital charges and supervisory scrutiny.

Key Areas of Regulatory Debate

Since the EBA guidance came into effect, banks have faced ongoing challenges in four key areas:

1. Defining the CSRBB Perimeter – Institutions must decide which assets and liabilities fall within CSRBB, ensuring transparency in any exclusions.
2. Separating Spread Elements – Banks must distinguish between market liquidity spreads and market credit spreads, avoiding misclassification of idiosyncratic credit risk.
3. Selecting a Measurement Approach – Options range from predefined shocks to more dynamic credit spread value-at-risk (CSVaR) models.
4. Allocating Capital and Setting Limits – Banks must align Pillar 2 capital allocations with CSRBB exposure while balancing risk and return in their liquidity reserves.

How Banks Are Adapting

Leading financial institutions are implementing various strategies to navigate these challenges:

• Enhanced CSRBB Modeling – Some banks adopt CSVaR models that factor in spread correlations, offering a more comprehensive risk assessment.
• Stricter Portfolio Concentration Limits – Institutions are imposing limits on exposure to specific credit quality bands to reduce CSRBB volatility.
• Integrated Risk Reporting – Banks are developing unified frameworks that merge CSRBB with IRRBB and liquidity risk monitoring.
• Scenario-Based Stress Testing – Many are running simulations to assess the impact of extreme credit spread movements on capital buffers.

Best Practices for Treasury Teams

To stay ahead of regulatory scrutiny and financial market shifts, treasury teams should:

1. Refine CSRBB Risk Frameworks – Establish clear policies on asset inclusions and exclusions.
2. Upgrade Analytics and Modeling – Leverage AI-driven insights to refine credit spread risk predictions.
3. Implement Dynamic Hedging Strategies – Adjust portfolio allocations proactively to manage spread volatility.
4. Engage with Regulators Early – Maintain open dialogue to ensure compliance interpretations align with supervisory expectations.
5. Optimize Liquidity Reserve Allocation – Balance credit spread risk against capital efficiency to maintain a resilient buffer.

Conclusion

The EBA’s latest CSRBB regulations have reshaped banking risk management, demanding a proactive and data-driven approach. Banks that fail to adapt risk exposing themselves to capital inefficiencies and heightened regulatory scrutiny. By refining measurement models and optimizing liquidity reserves, institutions can safeguard financial stability in 2025 and beyond.
