Federal Reserve and Bank of England are stepping up scrutiny of bank exposure to trading firms after a loss at Jane Street
What happened
The Federal Reserve and Bank of England are increasing oversight of how much risk banks carry from lending to trading firms like Jane Street. This move follows a loss at Jane Street that drew the attention of regulators. The shift drove roughly 824 billion dollars of market value.
Why it matters
Banks lend money and provide trading lines to firms that make markets. A large loss at one of those firms can ripple into the bank if the firm cannot pay what it owes. Regulators are now checking whether banks are too exposed to a single trading firm in a way that could threaten the bank's stability and tighten lending more broadly.
