The new guidelines introduce some changes to the monetary policy implementation framework. The provisions on counterparty eligibility have been revised such that the Eurosystem may take into account in its eligibility assessment information on capital, leverage and liquidity ratios of individual institutions. A new class of eligible assets, namely the 'non‑marketable debt instruments backed by eligible credit claims (DECCs)', has been introduced in the Eurosystem collateral framework. DECCs are debt instruments that: (a) are backed by credit claims that are also eligible as collateral with the Eurosystem on an individual basis; and (b) that have a dual recourse against the originating credit institution and against the underlying credit claims themselves. In the initial stage, only the domestic use of DECCs is envisaged. This restriction will remain in place until the Eurosystem fully develops the procedures for the cross-border use of DECCs.
