Vasseur joins the firm from UBS, where she spent the last four years as a cross asset execution trader, working across various different asset classes, including equities, fixed income, FX, ETDs, funds and hedge funds.
Prior to this, she worked in equity derivatives-based roles at GFI Group and Exane, based out of Paris and Geneva respectively.
While at GFI Group, Vasseur served as a broker for two years, where she provided trading desks with quotes on European single stocks options and D1 index products, as well as executing block and cross trades on different markets.
Similarly, she worked across equity derivatives sales trading during her two-year tenure at Exane, executing trades, hedging portfolios and providing asset managers, hedge funds and proprietary trading desks with quotes on listed options and futures.
Previously in her career, she has also served at firms including Deutsche Bank, Societe Generale and Rothschild & Co.
Vasseur’s appointment is the second hire for Kepler Cheuvreux this week, with the firm announcing yesterday that Olatayo Balogun had joined the KCx platform as an electronic sales trader, after six years at Berenberg.
Vasseur is Kepler Cheuvreux’s sixth hire this year, and marks the firm’s fourth high touch sales trader to join since the beginning of 2026.
