ECB after the Crisis: Synergies Between Monetary Policy, Banking Supervision, and Macroprudential Policies

Core Content

This paper examines the organisational and functional changes in the European Central Bank (ECB) following the financial crisis, focusing on the integration of monetary policy, banking supervision, and macroprudential policies. It explores the rationale behind assigning these new responsibilities to the ECB, the structures and working arrangements that support these functions, and the synergies and overlaps between them.

Main Functions of the ECB

The ECB is responsible for:

• Monetary Policy: Setting a single monetary policy for the entire euro area to ensure price stability.
• Banking Supervision: Supervising all euro area banks directly or indirectly through the Single Supervisory Mechanism (SSM).
• Macroprudential Policy: Contributing to financial stability by setting shared macroprudential tools and frameworks, often in coordination with national authorities.

Key Points

1. Rationale for ECB's Expanded Role

• The financial crisis exposed the weaknesses of a monetary union without a banking union, including inadequate information sharing and fragmented supervisory practices.
• The ECB has long had an interest in financial stability due to its monetary policy mandate.
• It possesses the necessary infrastructure, expertise, and institutional credibility to manage banking supervision effectively.
• The integration of banking supervision into the ECB is also part of a global trend, where central banks are increasingly involved in financial oversight.

2. Structural Differences and Synergies

• Monetary Policy: Centralised decision-making by the Governing Council, with NCBs handling operational tasks.
• Banking Supervision: Centralised for major institutions, with a mix of coordination and decentralisation for others.
• Macroprudential Policy: Shared responsibility between the ECB and national authorities, with the ECB having "topping-up" powers in specific areas.

3. Working Arrangements

• The ECB uses a network of technical committees to support its decision-making processes.
• The SSM builds on these historical ECB committees and operates under the ECB's leadership.
• The ECB's governance structure includes the Executive Board, Supervisory Board, and Governing Council, each with distinct roles and responsibilities.
• The ECB is accountable to the European Parliament and is reviewed by the European Commission every three years.

4. Decision-Making Process

• All three functions follow a three-stage process: preparation, decision, and implementation.
• Monetary policy preparation involves extensive data collection and analysis.
• Banking supervision requires detailed information on individual institutions.
• Macroprudential analysis involves assessing cross-border financial risks and implementing appropriate measures.
• The ECB ensures strict separation between monetary policy and banking supervision through institutional and procedural safeguards.

5. Synergies and Complementarities

• The ECB's monetary policy and banking supervision functions are mutually reinforcing, as both aim to ensure financial stability.
• Macroprudential policies complement monetary policy by addressing systemic risks that cannot be managed solely through price stability.
• The ECB's role in financial stability is now more prominent, with a focus on preventing and mitigating risks across the euro area.

6. Challenges and Concerns

• There are concerns about reputational risks and conflicts of interest, particularly if the ECB's monetary policy and supervisory roles come into tension.
• The "mental silos effect" refers to the fragmented analysis and information sharing that contributed to the crisis.
• The ECB has implemented the "separation principle" to ensure that monetary policy and banking supervision do not interfere with each other.

7. Institutional Developments

• The SSM was established in November 2014, marking a significant step in the creation of a banking union.
• The Single Resolution Mechanism (SRM) started in January 2016, with a focus on resolving failing banks.
• The Single Rulebook was introduced to harmonise prudential rules across the EU, including the implementation of Basel III reforms.

Summary of Synergies and Overlaps

• The ECB's monetary policy, banking supervision, and macroprudential functions are increasingly interlinked, with clear synergies in addressing financial stability.
• The ECB's centralised structure supports the implementation of a unified monetary policy and supervisory framework.
• The use of technical committees and regular reporting mechanisms (e.g., Financial Stability Committee) facilitates coordination and information sharing.
• The ECB's role in financial stability has expanded, but its primary objective of price stability remains unchanged.

Conclusion

The ECB's expanded role in financial stability and banking supervision represents a significant shift in its responsibilities. The paper highlights the importance of maintaining a clear separation between these functions to ensure the ECB's credibility and effectiveness. It also underscores the need for continued institutional development and coordination to address the complex challenges of the financial system in the euro area.
