3. Details of the initiative
A. Functional changes
With C7 Release 13.0, Eurex Clearing will introduce a new optional field called Prior UTI for external position transfers. The field follows the standard UTI specification, with a maximum length of 52 characters.
Only uppercase letters and numbers from 0 to 9 are permitted. Once submitted, the value remains unchanged throughout the position transfer workflow and cannot be amended.
Prior UTI is not applicable for internal position transfers or clearing house-entered position transfers. Members using the external position transfer upload are recommended to update to the new upload template to provide the Prior UTI field.
The FIXML Position Maintenance Report will be enhanced. The user-defined values of PosTransType / FIX tag 709 TxnTyp will be replaced by FIX standard values. From C7 Release 13.0 onwards, only FIX standard values will be supported for incoming and outgoing FIXML messages.
This change may require participants using FIXML to review and adjust their internal processing of position transfer types.
Classic Average Price services will be decommissioned towards the end of 2026. The exact decommissioning date will be communicated separately via circular. After the decommissioning date, attempts to use the Classic Average Price merge service will be rejected with the message “service is decommissioned”.
The de-merge of historical transactions will remain possible only if the transaction status is ADJUSTABLE and the transaction was merged no more than one week before the decommissioning date.
As an alternative to Classic Average Pricing, Members may use the Value Based Average Price functionality provided by Eurex Clearing.
For Single Stock Dividend Futures, the existing classification distinguishes between short-dated SSDFs and remaining SSDFs. With C7 Release 13.0, this classification will be expanded to include medium-term SSDFs.
With C7 Release 13.0, Eurex Clearing plans to introduce FIXML legal messages for Advanced Risk Protection level 1 and level 2 limit breaches. These FIXML legal messages will be available in English only. Manual slowdown and release of level 1 and level 2 limit breaches will not create any FIXML legal message.
In addition, German FIXML legal messages for level 3 breach and release for ECAG and ECC in the ARP service will be decommissioned.
C7 Release 13.0 introduces changes to product assignment and de-assignment. Clearing Members will be able to manage product assignments for their own Member ID independently for trading and corresponding clearing functionalities.
At Clearing Member level, removal of a product assignment will be possible either for trading only or for both trading and clearing. Product assignment at Account Owner level will not change and still result in the suspension of both trading and the corresponding clearing functionalities.
The corresponding clearing functionalities include take-up, receipt of external position transfer and receipt of transaction account transfer. A conversion will ensure that no differences arise between product settings in C7 Release 12.1 and C7 Release 13.0.
With C7 Release 13.0, Eurex Clearing will introduce higher limits for JPY Cash Deposit entries. For JPY, standard processing will apply for amounts up to or equal to JPY 37,500,000,000.00. Deposits exceeding JPY 37,500,000,000.00 and up to or equal to JPY 75,000,000,000.00 will require mandatory Four-Eyes Approval, while deposits exceeding JPY 75,000,000,000.00 will not be allowed. For all other currencies, the existing limits remain unchanged.
As part of planned security enhancements, Deutsche Börse Group will update its Public Key Infrastructure. This will introduce changes to certificate renewal timelines for Eurex C7.
The date when the certificates process provided in the Member Portal will use the new PKI infrastructure will be provided in due time.
Eurex Clearing will improve the resilience and scalability of transaction management via the FIXML interface. C7 will support multiple receivers per FIXML request queue, enabling greater throughput and flexibility.
As a result, responses and broadcasts triggered by client requests may no longer appear in the same order in which the requests were sent. Participants are required to test scalability settings in simulation before the introduction of C7 Release 13.0 to ensure that their software can consume out-of-sequence messages.
Clients who wish to opt in for simulation before 31 August 2026 are requested to contact their respective TKAMs. After this date, the functionality will be activated in the simulation environment as part of the release.
C7 Release 13.0 introduces changes to several reports, including updated fields, new fields, deleted fields and XML structure changes. Affected reports include, among others, the Position Transfer Summary report CB730, the Average Pricing report CB715, and the Member Capacity and Product Assignment reports TT721 and TT726.
