1. Introduction
Deutsche Börse has introduced a new Public Key Infrastructure (PKI) with a new Certificate Authority (CA) on 24 August 2026.
Starting 24 August 2026, the process provided in the Member Section of Deutsche Börse Group for generating client certificates for selected interfaces will automatically use the new DBAG PKI infrastructure.
The following trading related systems and interfaces are affected:
2. Required action
Participants using one of the affected interfaces must renew their client certificates over over the next few months prior to 18 December 2026.
Client certificates signed by the existing PKI/CA remain valid and may be used in parallel with certificates issued by the new PKI/CA until 18 December 2026. Usage of client certificates signed by the old PKI/CA beyond 18 December 2026 cannot be guaranteed.
All certificates issued under the previous PKI/CA must be renewed via the Member Section no later than this date.
3. Details
To support participants during the transition, a new column named “Certificate Type” has been added to the list of certificates displayed for each account in the Member Section of Deutsche Börse Group.
Each client certificate in the Member Section of Deutsche Börse Group can now easily be identified. Certificates signed by the existing DBAG PKI/CA are marked as “Old”, while client certificates signed by the new DBAG PKI/CA are marked as “New”.
Participants must complete the following steps for each affected interface:
This change does not affect any other T7 interfaces, such as T7 ETI, T7 FIX LF, or any T7 market data interface. Only the interfaces explicitly listed in this circular make use of Deutsche Börse Group signed client certificates and are therefore affected by this change.
