The Bank of Finland has updated its rules for counterparties and customers covering monetary policy operations and collateral, incorporating amendments made by the European Central Bank to key Eurosystem monetary policy framework guidelines. The revised rules enter into force on 30 March 2026. The update reflects changes to the ECB Guideline on the implementation of the Eurosystem monetary policy framework, the valuation haircuts applied in that framework, additional temporary measures relating to Eurosystem refinancing operations and collateral eligibility, and the management of collateral in Eurosystem credit operations. The Bank of Finland’s accompanying document on implementation of monetary policy operations and collateral management has also been revised, with sections on the Bank of Finland’s framework for additional credit claims removed.
