• Leverage at hedge funds has reached unprecedented levels, with the largest funds driving borrowing.
  • Life insurers maintain leverage in the upper historical quartile amid a pivot toward private credit.
  • Federal regulators warn these conditions create material risks to broader financial stability.

Leverage among hedge funds and life insurers is hovering at or near historic highs, creating potential fault lines in the financial system, according to the latest Federal Reserve Financial Stability Report and subsequent commentary from officials.

For hedge funds, gross leverage has hit unprecedented levels since records began in 2013. The concentration is particularly acute, with the largest 10 funds accounting for a staggering 40% of total repo borrowing. Leverage ratios for some funds have ballooned to as high as 18:1 as of the third quarter of 2024, according to the report.

Much of this activity is tied to cash-futures basis trades in US Treasury markets, a strategy that requires substantial leverage to turn a profit. The Fed explicitly warned that this buildup echoes the dynamics that exacerbated the 2020 Treasury market dislocation, raising concerns that dealer intermediation could be insufficient if highly leveraged funds are forced to unwind positions rapidly.

Meanwhile, the life insurance sector is navigating its own leverage challenge. The Fed noted that leverage in the industry "remained in the upper quartile of its historical distribution" through the first half of 2025. This trend is being fueled by a strategic shift away from traditional public fixed income and into higher-yielding, less liquid assets like private credit.

Life insurers now hold $849 billion in private placements, representing 14% of their total invested assets, the report detailed. While industry leaders like MetLife and Lincoln National have publicly asserted that their risk management frameworks remain robust, the Fed's analysis suggests the growing complexity and scale of these exposures could lead to liquidity mismatches and credit losses if market conditions deteriorate.

Efforts to reach several major hedge funds for comment on the report's findings were not immediately successful. A spokesperson for a large insurance trade association, who asked not to be named as they were not authorized to speak publicly, said the industry's capital positions are "strong and well-managed to withstand economic cycles."

The regulatory scrutiny is intensifying against a backdrop of post-2008 banking regulations that may have unintentionally pushed leverage into the less-regulated nonbank sector. Policymakers at the Bank for International Settlements have voiced concerns about a potential "doom loop" risk if life insurers face large, illiquid credit losses during a period of market stress.

With expectations for potential Fed rate cuts providing some market stability, the immediate risk of a disruption may be contained. However, the central bank's report makes clear that the system's vulnerability to abrupt swings in rates or liquidity has meaningfully increased, setting the stage for potential regulatory action.
