In line with its statute, the Eurosystem provides credit only on a collateralised basis (See “Introduction”). Assets that are pledged to the Eurosystem as security for its central bank credit operations are called "collateral". To be accepted, these assets must be eligible, i.e. fulfil certain criteria, as further specified in the “General framework” as well as “Temporary framework” (see also Legal framework for monetary policy instruments). This section supports counterparties to identify which assets can be used and how to submit them.
