(22)Point (d) of Article 59(4) of Regulation (EU) No 909/2014 requires that CSD-banking service providers mitigate liquidity risks with qualifying liquid resources in each currency. As a result, non-qualifying liquid resources cannot be used to meet the requirements set out in that Article. Nevertheless, nothing precludes non-qualifying liquid resources, such as currency swaps, from being used in the daily liquidity management in addition to the qualifying liquid resources. This is also consistent with international standards reflected in CPSS-IOSCO Principles. Non-qualifying liquid resources should therefore be measured and monitored for that purpose.
