OneClearstream migration timeline

The OneClearstream service level provides customers with a single point of access to all T2S markets with comprehensive instrument coverage.

We continue to activate our integrated OneClearstream service offering in new markets, as we harmonize our services allowing customers to benefit from advantages across multiple areas of our business.

As more markets migrate to OneClearstream, the scope of available assets accessible via our German CSD will significantly increase with both new links and new asset types becoming available to customers. Those securities held at our German CSD will be accepted either with collective safe custody (CSC) status or as non-collective safe custody enabled for T2S (NCSC-T).

As part of the market rollout, we will be going live with our new asset servicing partnership model to offer the best possible asset services for settlement in T2S via the expertise of our local partners. This will provide customers with full harmonization of asset services and connectivity channels across Clearstream.
