Hedge fund leverage hits 4-year high as $165 billion selloff looms

Global hedge fund net leverage has climbed to its highest level in four years, setting the stage for a volatile quarter-end as JPMorgan estimates $165 billion in forced equity sales.

Global hedge fund net leverage reached a four-year high in June, driven by aggressive buying and mark-to-market gains, Goldman Sachs prime brokerage data shows.

"The market is carrying higher long positions, higher leverage, and that creates structural vulnerability," said Lee Coppersmith, chief analyst of equity flow at Goldman Sachs. "Even the strongest long-term themes don't trade in a vacuum."

Gross leverage hit about 294%, a five-year high, according to Goldman data cited by Reuters. The past four weeks saw the steepest leverage increase in roughly five years, fueled by net buying and rising portfolio values. At the same time, implied volatility in large-cap tech stocks has expanded relative to the broader market even as prices rose — a sign investors are pricing in greater fragility. JPMorgan strategist Nikolaos Panigirtzoglou warned that stretched semiconductor positioning is raising the risk of more frequent value-at-risk shocks, noting that the sector's share of global equity value is now more than six times its share of revenue.

The near-term trigger is mechanical. JPMorgan estimates quarter-end rebalancing could drive up to $165 billion in equity sales as June closes, with Japan's $1.9 trillion Government Pension Investment Fund accounting for about $60 billion alone. US pension funds add another $55 billion, while Norway's and Switzerland's sovereign funds contribute tens of billions more. The selling meets a market already on edge after the Federal Reserve under Chair Kevin Warsh held rates steady and signaled a possible hike this year, repricing front-end rate expectations.

The leverage buildup coincides with a rotation beneath the surface of the AI trade. Goldman data shows Mag 7 long-short exposure has fallen to a one-year low, while overall US tech sector exposure sits near a five-year high. Money is flowing deeper into the AI supply chain — semiconductors and Asian chipmakers — with the semiconductor sub-sector on track to be the most net-bought industry globally for a second consecutive year. Some capital is rotating into financials, cyclicals, and European and Asian markets, but without sacrificing AI allocations.

Oil Market Adds Another Layer of Fragility

Crude oil markets are flashing their own warning signals. After the US-Iran peace deal removed a key geopolitical risk premium, Brent crude has given back nearly all of its war-driven gains. Managed money funds have net sold roughly $25 billion in crude over the past seven weeks, and short positions surged to a record last week. Net long positions have fallen below pre-conflict levels, according to Goldman's Rob Quinn. "Investors digested the geopolitical risk with unusual speed and have shifted focus back to rates and Fed policy," Coppersmith said.

Leverage ETFs Amplify Market Mechanics

Systematic factors are playing an increasingly important role beneath the surface. In markets like South Korea, dealer gamma hedging for leveraged ETFs has exceeded 20% of average daily trading volume on high-volatility days, Goldman data shows. That mechanical rebalancing acts as a structural amplifier — boosting momentum on the way up and accelerating declines when the trend reverses. Combined with elevated fund leverage and concentrated positioning, the mechanism creates a setup where volatility becomes self-reinforcing.

The S&P 500 closed the holiday-shortened week at 7,500.58, up 0.93%, after Monday's rally on the US-Iran deal pushed the index higher. Nine of 18 Fed officials now pencil in at least one rate hike this year, with six seeing two. Thursday's PCE inflation print will be the next major test for rate expectations.
