JPMorgan hired one of BNP Paribas' top quants in Paris

2 July 2026

Working as a top French quant with top French credentials at a top French bank in France is the pinnacle of the French financial services existence. But now that US banks are also big in Paris, and are competing for staff in the French capital, there are higher mountains to climb.

Vincent Berthelemy, the head of quantitative investment strategies (QIS) and asset allocation strategy at BNP Paribas, has moved to a new perch at JPMorgan in Paris. At JPMorgan, Berthelemy will be head of QIS portfolio construction.

Berthelemy didn't respond to a request to comment for this article. Nor did JPMorgan. BNP Paribas declined to comment on his departure.

Berthelemy's new job appears bigger than his old one. He spent four years at BNP Paribas and previously worked for SocGen, Lyxor Asset Management and Investcorp in both London and NYC. BNP insiders say he moved back to Paris with BNP last year.

Thierry Bernas is also thought to have left BNP's QIS structuring team. Bernas, who was based in London, didn't confirm this and nor did BNP. The FCA register shows him leaving the French bank in mid-June.

JPMorgan employs around 1,000 people in Paris up from 250 at the time of Brexit. Some in the rates trading team have been moving back to London. Quant roles are presumably more firmly planted on French soil.
