Summary
SocGen's Bernstein joint venture is accelerating its London equities hiring, bringing on senior talent from rival institutions as part of a multi-year strategy to strengthen its cash equities and research operations. Bernstein confirmed the departure of Tristan Hedley from Berenberg, where he spent 11 years as an equities sales trader and was regarded as a respected market participant. The FCA Register documents his departure on July 1, 2026. Sources indicate Hedley's hiring represents a deliberate recruitment of high-caliber sales trading talent to bolster Bernstein's institutional client coverage.
The venture is also in advanced recruitment discussions with Katrina Pattemore, an experienced equities trader who quietly exited BNP Paribas in late 2024. While her formal arrival has not been officially announced, multiple market sources expect her appointment to Bernstein's London high-touch sales trading team to proceed imminently. This dual hire signals a focused effort to build out a competitive equities sales trading franchise in a strategically important financial center.
The talent acquisition initiative sits within a broader SocGen equities expansion directed by Chief Executive Slawomir Krupa. Beyond sales trading recruitment, the bank has hired 20 personnel for a new cash prime brokerage push and is building quantitative investment strategies capabilities, including systematic equity dispersion strategies. This diversified expansion reflects SocGen's ambitions to scale its equities franchise ahead of its planned 100% acquisition of the Bernstein venture by 2029.
Performance metrics underscore the strategic urgency of this buildup. SocGen's equities sales and trading revenue grew less than 5.5% in Q1 2026, substantially trailing competitors—Citi reported 38% growth in the same period. The significant performance gap has accelerated SocGen's investment in senior talent and product capabilities as a competitive response. Though Bernstein declined to comment on specific hires, the pattern of London-based recruitment and the strategic investments in prime brokerage and quantitative products reflect a calculated repositioning of SocGen's equities platform for stronger institutional market presence.
