The European Insurance and Occupational Pensions Authority (EIOPA) has launched a Call for Evidence to gather inputs for a future toolkit on defined contribution (DC) pensions, intended to support policymakers, social partners, regulators and supervisors as pension gaps widen and systems shift from defined benefit to DC arrangements. The planned toolkit is positioned as practical guidance and principles that can be tailored to national circumstances, reflecting differences across EU Member States in pension gaps and the maturity of supplementary pensions. It is expected to cover maintaining flexibility in DC systems amid changing labour market conditions, the design of accumulation and decumulation phases, and principles to help ensure DC plans deliver value for money. EIOPA is seeking case studies, data, statistics, research and lessons learned from international experience. Submissions via the online EUsurvey are due by 28 November 2025, and responses will be treated as public documents unless respondents request otherwise.
