Executive Summary

FINMA confirms in its ex-post evaluation that the 2019 circular on interest rate risks in the banking book has fundamentally proven effective. Small and medium-sized banks were able to catch up in advanced risk management methods, strengthening the stability of the Swiss banking sector during volatile interest rate phases. The partial revision planned for 2026 aims to bring targeted improvements and implement the updated Basel interest rate shock scenarios – a step that will once again test the balance between international harmonization and national flexibility.

Critical Key Questions

  1. How much regulatory autonomy does Switzerland retain when Basel III updates are automatically adopted – and where is the line between sensible harmonization and regulatory takeover?

  2. Do smaller institutions really benefit from tightened standards, or does regulatory density lead to creeping market consolidation in favor of large banks?

  3. What innovation potential arises from more advanced risk models – and what new systemic risks could emerge from their homogenization?

Scenario Analysis: Future Perspectives

Short-term (1 year):
Banks begin implementing the 2026 revision. Compliance costs rise moderately while institutions tighten their validation processes. Proportionality adjustments could provide relief for smaller banks.

Medium-term (5 years):
The Swiss banking landscape shows further professionalization in interest rate risk management. Market consolidation is possible among institutions that cannot handle the technological investments. The question of effectiveness in extreme interest rate scenarios remains unanswered.

Long-term (10-20 years):
Increasing standardization could lead to a "monoculture" in risk management – all banks react similarly to interest rate shocks. This paradoxically increases systemic risk. Alternative financial actors could exploit regulatory gaps.

Main Summary

a) Core Topic & Context

FINMA takes stock after six years of its tightened requirements for banks' interest rate risk management. The evaluation occurs during a phase of rising interest rate uncertainty and against the backdrop of international regulatory harmonization through the Basel Committee.

b) Key Facts & Figures

  • Circular 2019/2 in force since January 1, 2019
  • Decline in institutions flagged for interest rate risks in the banking book
  • Partial revision planned for 2026
  • July 2024: Basel Committee publishes updated interest rate shock scenarios
  • Small and medium-sized institutions have caught up with advanced methods

c) Stakeholders & Affected Parties

  • Directly affected: All Swiss banks, especially small and medium-sized institutions
  • FINMA as regulatory authority
  • Basel Committee as international standard setter
  • Bank customers indirectly through possible effects on credit conditions

d) Opportunities & Risks

Opportunities:

  • More stable banking system through professional risk management
  • Improved proportionality rules could help smaller banks
  • International comparability strengthens Swiss financial center

Risks:

  • Compliance costs could overwhelm smaller institutions
  • Homogenization of risk models increases systemic risks
  • Overregulation could hinder innovation

e) Action Relevance

Bank boards should now incorporate the upcoming partial revision into their strategic planning. Validation requirements will be tightened – appropriate resources and expertise must be built up. Proportionality adjustments may offer scope for design for smaller institutions.
