International Monetary Fund: Rapid expansion of hedge funds may amplify market risks

The International Monetary Fund (IMF) pointed out in Chapter 2 of the Global Financial Stability Report released on the 6th that we should be alert to the risks that hedge funds may bring to macro-financial stability. The report said that the scale of global hedge fund assets has grown too fast, which can easily amplify price dislocations and tight liquidity amid capital market fluctuations. Once it encounters a serious negative impact, it may trigger systemic risks.

Chapter 2 of the Global Financial Stability Report usually focuses on structural issues or frontier financial risks in specific areas, and is generally released before the Global Financial Stability Report.

The report said global hedge fund assets grew from US$4 trillion in 2013 to US$13 trillion in early 2026. Although accounting for only about 5% of non-bank financial investment institutions, hedge fund assets have grown significantly faster than most other non-bank financial sectors since the global financial crisis.

The IMF pointed out that while hedge fund assets are expanding rapidly, leveraged financing has also become an important way for them to expand their investment scale. The so-called leverage refers to making larger investments with less own funds through borrowing funds and other methods. Leverage can magnify gains, but it can also magnify losses, making financial institutions more vulnerable when markets fall.

When markets experience severe volatility, high leverage can force hedge funds to quickly sell assets to meet financiers' margin requirements or pay down debt. If a large number of funds reduce their asset holdings at the same time, it may further depress asset prices and intensify market liquidity tensions, thereby amplifying market volatility.

In addition, hedge funds have extensive financing, trading and derivatives business relationships with financial institutions such as large dealer banks. If a hedge fund suffers serious losses or even defaults, related risks may be transmitted to banks and other financial market participants through these business relationships, and further affect the stability of the financial system.

The report believes that as the hedge fund sector continues to expand, the impact of its potential risks on macro-financial stability deserves close attention. The report recommends strengthening the collection and risk monitoring of hedge fund-related data, and combining targeted prudential regulatory measures and market structure reforms to improve the industry's ability to withstand market shocks.
