Liquidity-providing operations of the Eurosystem monetary policy must be based on adequate collateral.
The Eurosystem accepts two types of assets: marketable assets and non-marketable assets. As a rule, no distinction is made between the two asset classes with regard to the quality of the assets and their eligibility for the various types of operations.
The eligibility criteria and the rules for the use of collateral are defined in ECB Guidelines and in Instructions of the Banco de Portugal No 3/2015 and 7/2012 (see Related pages). The criteria used to assess the eligibility of assets take into account the type of asset, the place of issue, the currency of denomination, the type and place of establishment of the issuer, debtor and guarantor and the credit quality of the asset, issuer, debtor and guarantor.
The assets eligible for monetary policy liquidity-providing operations may also be used to guarantee intraday credit.
Eurosystem counterparties may use eligible assets on a cross-border basis, i.e. they may resort to credit operations with the central bank of the Member State in which they are established by making use of assets that can be settled in any securities settlement system considered eligible by the Eurosystem for that purpose (for further details, see related ECB webpages).
