Fed, BoE Tighten Checks on Bank Exposure to Trading Firms After Jane Street's $15 Billion Loss
3 articles · Updated · Financial Times · Sep 21
Summary
$15 billion in July losses at Jane Street pushed the Federal Reserve and Bank of England to intensify reviews of how global banks finance major trading firms and market makers.
Regulators are asking banks about exposure to firms including Jane Street and Citadel Securities, focusing on risk appetite, intraday exposure swings and whether controls held up during the AI-driven sell-off.
The scrutiny centers on prime brokerage and related financing, where banks provide leverage, clearing and trade funding and could absorb losses if a large client defaults.
Jane Street still generated $40 billion in net trading revenue by early August, but the scale of the hit from Situational Awareness sharpened concerns that some market makers now carry risks closer to hedge funds.
The review fits a broader push to map risks from non-bank financial intermediaries as trading firms grow more systemically important and intraday exposures keep rising.
