Clearstream Banking1 informs clients that effective

27 November 2023

the OneClearstream service will be activated for securities issued by Euroclear Finland (EFi) and therefore make all Finnish securities eligible in Clearstream Banking AG (CBF) and LuxCSD. All Finnish ISINs will receive Collective Safe Custody (CSC) status.

Clearstream Banking will continue to access the Finnish market via the Clearstream Banking S.A. (CBL) direct link to Euroclear Finland operated by Citibank Europe plc.

For the avoidance of doubt, direct settlement with domestic counterparties in Euroclear Finland will not be possible for CBF and LuxCSD, as described in the Market Link Guide - FinlandFor guidance on transferring securities from CBL to CBF and vice versa, clients are invited to consult the Realignment Guide.

Clients are reminded that the description of the future OneClearstream Investor-CSD service can be found on the OneClearstream page published on the website.

Scope of securities eligible for the OneClearstream service

Impacted ISINs

All Finnish ISINs will be migrated to OneClearstream. The finalised list of the impacted ISINs is enclosed with this announcement.

Clients are reminded that all OneClearstream asset servicing bookings in T2S-eligible proceeds and the related reporting will be done at the clients’ sub-account level.

Ahead of the OneClearstream activation, clients are requested to make sure that each sub-account has an appropriate account setup and is subscribed to the relevant reporting.

To ensure a smooth OneClearstream activation, clients’ sub-accounts without the appropriate reporting subscription will be subject to a default reporting setup by Clearstream Banking as described in Announcement C18014: Automatic subscription to OneClearstream Asset Servicing reports.

Corporate actions on flows (market claims, transformations and buyer protection)

For Clearstream Banking AG (CBF) and LuxCSD clients, using the OneClearstream service, corporate actions on flows will be subject to OneClearstream service level as described in the OneClearstream Client Handbook (for example, payment of all market claims proceeds in T2S, asset servicing reporting in OneClearstream standards). 

There is no change of service level for Clearstream Banking S.A. clients. Please refer to the Market Link Guide – Asset servicing – Finland for additional details.
