Euronext FX has named Simon Gallagher as its new chief executive, according to a 5 November report by Colin Lambert at The Full FX that quotes the company. Gallagher succeeds Nicolas Jégou, who has run the institutional FX platform from New York for nearly four years and is moving to another role within Euronext. Gallagher also retains his positions as chief executive of Euronext London and head of global sales. This is a leadership change at the FX venue, not the appointment of the Euronext group’s next chief executive, a separate succession process reported earlier in November.[1][2]
The Full FX reports that Euronext FX has averaged a little over $31 billion in daily trading volume during 2026, about 40% higher than in 2023. The comparison is a broad platform-performance indication rather than a controlled comparison of execution quality. It does not reveal the amount earned on each trade, the geographic customer split or whether any single product contributed disproportionately to growth.[1][2]

Gallagher has spent roughly 24 years within Euronext and its predecessor businesses, according to the report, holding positions in equities, cash markets, derivatives, business planning and Irish market governance. That background matters because institutional FX platforms compete not only on a quote stream but on the full network around it: customer onboarding, credit, relationships with liquidity providers, trading sessions, rulebook design and data products.[1][2]
Which changes would make the appointment operationally important
For liquidity providers and brokers, a chief-executive change is potentially meaningful when it changes venue access or commercial terms. No such change is announced in the report. The new leader may influence pricing, service design and sales priorities over time, but there is no basis for claiming that spreads, matching rules or customer contracts were altered on 5 November. Any future operational shift requires its own notice or verified term sheet.[1][2]
The useful watchlist is concrete: Euronext FX monthly and quarterly volume by instrument, announcements about new liquidity providers and order types, and any disclosed changes in connectivity or fee schedules. Until such evidence appears, the news is a management appointment accompanied by a reported growth benchmark—not a tested improvement in trade outcomes.[1][2]
