Get ready for T2S

Clearstream has been supporting our customers throughout the journey to T2S with exhaustive readiness measures, like workshops, detailed documentation, webinars and bilateral meetings with the Relationship Management teams and Clearstream’s T2S experts. The following pages will give you detailed guidance on what you need to do to achieve readiness for T2S, no matter whether you wish to use any of Clearstream’s CSDs or the ICSD to access T2S.

ICSD Access

The ICSD approach minimises adaptations required from a customer perspective. Only mandatory changes are passed through. We describe such changes in our impact assessment documents published on our website on our Information by wave page.

Investor CSD Access

T2S Forms

In order to set up your accounts for T2S, either as DCP or ICP, a set of specific T2S forms is required.

Readiness documentation

Clearstream has prepared a series of documents describing its future offering in line with the migration to T2S and showing the areas where Clearstream will modify its existing procedures. This allows Investor CSD customers to identify their implementation needs.

Detailed Functional Descriptions

The Detailed Functional Descriptions describe the advanced functions and services of Clearstream’s Investor CSD model. They are also updated regularly to take into account changes initiated by the ECB (Eurosystem).

The Detailed Functional Descriptions (DFDs), are available here (only to registered Premium users).

Glossary of T2S Terms

Our T2S Glossary provides definitions and a short description of the main abbreviations, acronyms and terms related to the future clearing and settlement procedures with T2S in both English and German.

The Glossary is available here.
