Equity Derivatives: Change of capacity group and settlement location for selected Single Stock Options settled in SEK

1. Introduction

Eurex Clearing AG is aligning its settlement infrastructure, as part of Clearstream's Project UNO (Unified for New Opportunities), to reflect the structural changes at Clearstream Europe AG (CEU). Effective with the market activation of UNO Wave 3, four Single Stock Options currently assigned to the capacity group "Physical SEK - CBF/T2S" will be migrated to the capacity group "Physical SEK", and the corresponding security settlement location will change from 6-series accounts in Creation (code "CBF-i") to accounts at CEU/T2S (code "CBF") for all products in the capacity group “Physical SEK”.  

These changes ensure consistency with Clearstream's unified post-trade infrastructure and streamline the settlement process for affected products. The changes will take effect on 11 September 2026 in production and have been available in simulation since 10 June 2026.  

For further information on the simulation opportunities, please refer to the Eurex Clearing Readiness Newsflash from 20 May 2026. All Eurex Clearing Members holding positions or trading in the affected Single Stock Options are impacted by this change. 

These changes are part of the broader UNO Wave 3 market activation. Learn more about Project UNO and Eurex Clearing's related readiness activities on our dedicated initiative page under the following link: Project UNO. 

2. Required action

Clearing Members trading or holding positions in the four affected Single Stock Options should note the following: 

• Capacity group change: The capacity group for the products listed below will change from "Physical SEK - CBF/T2S" to "Physical SEK". Members must ensure that their internal systems and capacity group mappings are updated accordingly. 
• Settlement location change: The security settlement location for the capacity group "Physical SEK" will change from settlement on 6-series accounts in Creation (code “CBF-i") to settlement at CEU/T2S (code “CBF”).

3. Details of the initiative
 

Clearstream's Project UNO consolidates the settlement infrastructure of Clearstream Europe AG (CEU) by making instruments T2S-eligible so that all transactions can settle on the CEU/T2S platform aiming for a decommissioning of 6-series accounts. This initiative simplifies the post-trade landscape and reduces operational complexity for market participants. Further details on Project UNO are available in the Clearstream UNO Rollout Documentation. 

3.2 Affected products 

The following four Single Stock Options are affected by this change of the capacity group: 

Please note that with UNO Wave 3 all other products being in the capacity group “Physical SEK” already will change their settlement location for physical deliveries to CEU/T2S.
