The European Insurance and Occupational Pensions Authority has published updated technical documentation for the methodology used to derive EIOPA’s risk-free interest rate term structures, with revisions driven by the 2025 Deep, Liquid and Transparent Assessment and by Bulgaria’s adoption of the euro from 1 January 2026. All changes will become effective from January 2026 onwards. The updated technical documentation is available in the ‘Risk-free interest rate term structures’ section of EIOPA’s website under Background Material.
