Euronext and Clearstream start a new partnership to advance the continued development of Euronext Clearing’s collateral management services across repo and other asset classes. The additional collaboration with Clearstream strengthens Euronext Clearing’s infrastructure to deliver scalable and efficient clearing solutions tailored to the evolving requirements of European and international market participants.

As part of this initiative, Clearstream will serve as a triparty agent (TPA) for Euronext Clearing, facilitating advanced collateral management capabilities. Clients will benefit from automated, flexible and operationally streamlined solutions that enhance margin and balance sheet optimisation. Clearstream will act as an independent third party, handling the collateral selection, valuation and substitution to ensure compliance with eligibility criteria while minimising operational complexities. In addition, Clearstream will manage settlement and custody services, provide robust regulatory reporting, and support liquidity and risk management objectives.

The go-live of this enhanced service offering is scheduled for November 2025.

Integrated post-trade infrastructure to strengthen European capital markets 

The partnership aligns with Euronext’s and Clearstream’s ambitions to strengthen European capital markets by providing robust, scalable and efficient pan-European post-trade infrastructure.

It represents a significant milestone in Euronext’s strategy to expand its 25-year strong  repo clearing franchise into a unified, pan-European clearing model delivering greater efficiency and value to clients across the continent and beyond. The agreement supports the upcoming launch of the initial phase of Euronext Clearing’s Repo Expansion Initiative, the Repo Foundation, scheduled for June 2025 —opening access to international participants and introducing broader product capabilities. Over the past three years, Euronext Clearing has transformed from a national central counterparty into the third-largest European clearing house, integrating operations across multiple countries, markets, and asset classes.

Clearstream adds its 30-years expertise in supporting market participants worldwide to efficiently manage and mobilize their collateral assets in changing market environments. In a strategic initiative, the post-trade service provider has consecutively enhanced its collateral management, lending and liquidity services, connecting with central counterparties (CCPs), exchange providers, and other central securities depositories (CSDs) to maximize much-needed liquidity at global markets.  Clearstream’s innovative data and digital collateral solutions complete the joint offering, supporting Euronext Clearing with AI-based collateral schedule creation and liquidity optimisation data insights.

Anthony Attia, Global Head of Derivatives and Post-Trade at Euronext, said: “This collaboration with Clearstream marks an important step in the execution of our ‘Innovate for Growth 2027’ strategy, reinforcing Euronext Clearing’s ability to deliver cutting-edge collateral and clearing solutions. As we prepare to launch the Repo Foundation in June 2025, this alliance supports the broader expansion of our repo clearing services across Europe. By working with Clearstream, we are scaling our infrastructure, enhancing collateral mobility, and building a more resilient, client-focused clearing ecosystem.”

Sam Riley, CEO at Clearstream Securities Services, said: “As financial markets become more unpredictable, demanding greater speed and efficiency, we stay committed to empowering our clients with reliable and scalable state-of-the-art solutions. We are delighted to partner with Euronext Clearing to deliver innovative collateral management solutions that enhance market efficiency and support sustainable growth. This collaboration reflects our commitment to building a stronger and more accessible European capital market that is well-equipped to navigate the complexities of the financial landscape of today and tomorrow.”
