BIS warns hedge fund leverage could amplify market shocks

The Bank for International Settlements has highlighted fears that the growing use of leverage by investment funds could amplify market shocks, following the near-collapse of AI-focused hedge fund Situational Awareness. The Basel-based institution noted the fund's July crisis in its latest quarterly review, warning that rising leverage could magnify market movements and create vulnerabilities for both investors and central banks.

Situational Awareness, established by former OpenAI researcher Leopold Aschenbrenner, faced significant pressure in July as sharp declines in its AI-related investments led banks to demand additional collateral. In response, the fund agreed to sell most of its public equity portfolio to Citadel, founded by Ken Griffin, to address liquidity issues stemming from the market sell-off.

The BIS emphasized that hedge funds now play a central role in global financial markets, creating a "fragile situation" particularly for strategies reliant on short-term borrowing and readily available market liquidity. The central bank has repeatedly warned this year that vulnerabilities connected to the AI investment boom could spread throughout financial markets if valuations decline sharply or financing conditions tighten.

For now, markets have remained resilient despite these risks, but their ability to withstand potential stresses remains uncertain, especially if government bond yields keep rising, as higher yields could tighten financial conditions and exacerbate difficulties for leveraged investors.
