When transferring eligible marketable assets issued in a CSD or ICSD, counterparties make use of the securities settlement systems (SSSs) which are regularly assessed and deemed eligible.
For details, see Eligible SSSs
For non-marketable assets (i.e. credit claims and Irish retail mortgage-backed promissory notes), the Eurosystem NCBs have implemented national handling solutions which differ from country to country.
For details, please refer to CCBM market practices or the individual NCB website.
