Euronext opens its CSD network to Amsterdam, Brussels and Paris trades

Euronext Securities has launched a settlement model for equities and euro-denominated ETPs traded on Euronext Amsterdam, Brussels and Paris. These instruments can now settle within its CSD network, alongside the markets it already serves in Athens, Copenhagen, Milan, Oslo and Porto.

The exchange group announced on 24 September that the “European Offering” had gone live as planned on 21 September. It said “first adopters are already live”. More clients are joining through issuer agents and custodians, though it did not name any.

What changes

Euronext describes two parts to the model:

• Choice: trading members can choose where their trades on the three markets settle, “introducing genuine competition into post-trade”.
• Consolidation: firms can bring settlement across several markets into one infrastructure. Euronext says this shortens custody chains for trading members.

Settlement remains interoperable with other CSDs through the ECB’s TARGET2-Securities platform. Euronext says this comes “at the cost of a domestic transaction”.

For issuers, Euronext offers itself as an alternative issuer CSD. It stresses that the choice remains “entirely the issuer’s own decision” under the open-access framework of the Central Securities Depositories Regulation. Euronext says it will manage a switch end to end with the issuer’s paying agent, with no impact on shareholders or existing programmes.

The terms are pitched aggressively: issuance services are free, “with no migration fee, no onboarding fee and no ongoing issuance or safekeeping fees”.

The policy pitch

Euronext ties the launch directly to the EU’s Savings and Investments Union (SIU) and the Market Integration and Supervision Package. It says Europe has “close to 30 CSDs, while the US has one”, and calls the offering “a concrete, working example of integration delivered in practice”. It plans to add features over time and describes a broader ambition for “a truly pan-European partnership”.

Why it matters

For settlement and operations teams, the immediate questions are practical:

• Where to settle: choosing the settlement location for each venue and instrument affects realignment flows, cross-CSD settlement over T2S and fail management, especially as the EU moves to T+1 in October 2027.
• Issuer migrations: these change where corporate actions are processed and where registers sit. Agent banks and custodians will need to track which ISINs move, and when.

For issuers, the free-of-charge offer is a strong commercial lever. Uptake will show whether open access under CSDR works in practice after years of being largely theoretical. Rival CSDs are likely to respond on price, and the policy debate in Brussels about consolidating post-trade infrastructure now has a live market test.
