In MACCs, a “pool” (with pool ID, pool class and collateral account) is assigned to a rating source selected by the participant (ICAS, IRB, etc.). One purpose of the pool is to book transactions to the specified collateral account and, if necessary, to separate stocks of credit claims.
Initially, one monetary policy pool will be available for each participant. Furthermore, technical preparations have been made for the use of additional eligible credit claims (so called ACC), and two additional pools have been set up in MACCs for this purpose.
The creation of further pool classes for T2-Contingency and for the use of DECCs is envisaged in subsequent developmental stages.
A decision on whether or not to set up additional monetary policy pools will be taken by the ECB.
