Europe’s CSDs modernize as Euronext opens settlement choice

Europe’s four largest central securities depositories — Euroclear, Clearstream, Euronext and SIX — are upgrading technology and simplifying client interfaces as Euronext prepares to let market participants choose a CSD for settlements in Amsterdam, Brussels and Paris from Sept. 2026.

Euronext confirmed that from September 2026 participants trading on its exchanges will be able to settle equities with Euronext Securities, Euroclear, Clearstream or SIX. Regulators approved Euroclear and Clearstream as alternative CSDs alongside Euronext’s unit. Executives said the prospect of multiple providers has already put downward pressure on some fees.

The firms are consolidating customer-facing systems and standardizing access to support cross-border settlement and shorter settlement cycles such as T+1. Euroclear has introduced a consolidated reporting tool that gives clients a single view across its CSDs. Clearstream described a unified front-end for its ICSD and CSD services and shared collateral and corporate action platforms. SIX has combined its digital exchange capabilities with its securities services business.

Technology investments span cloud migration, application programming interfaces, artificial intelligence, tokenization experiments and distributed ledger pilots. Euroclear is developing a Digital Financial Market Infrastructure platform, Clearstream is building its D7 digital post-trade platform, and SIX is expanding its digital exchange tools. Executives say the platforms aim to provide common access points for both book-entry securities and tokenized instruments.

The Eurosystem settlement platform T2S remains part of integration plans. Participants reported recent operational incidents and urged stronger resilience and faster change-management processes. Some CSDs are asking the European Central Bank to consider tiered T2S pricing to reduce costs for high-volume asset classes such as ETFs in the context of the EU’s Savings and Investment Union.

Fees and cost structure have been a focus at recent industry events. A report comparing European CSD and ICSD fees with U.S. levels prompted debate; CSDs noted the comparison does not reflect structural differences between a single large U.S. market and multiple national CSDs in Europe. Executives acknowledged opportunities to simplify price schedules and eliminate low-value ancillary charges, estimating roughly 20–30% of line items relate to paper, reconciling or other hygiene tasks that could be removed through governance changes.

Industry executives commented on the pace of change. Sam Riley, chief executive of Clearstream Securities Services, described post-trade activity as “becoming quite sexy.” Francisco Bejar, head of custody at SIX, observed that infrastructures are moving from being perceived as static to being front of innovation. Sebastian Danloy, Euroclear’s chief business officer, noted rapid technology adoption since he joined the sector 18 months ago, while Pierre Davoust, head of Euronext Securities, called AI “a big productivity shock” with potential to expand service delivery.

Europe’s post-trade landscape remains fragmented, with local CSDs in many countries alongside large cross-border operators. Regulators and market participants continue to seek greater consolidation and interoperability to reduce friction and cost for cross-border investors. The four CSDs are positioning themselves as record keepers for legacy issuance and as providers of interfaces to digital-asset services.
