The global investment fund industry has expanded significantly, reaching an aggregate net asset value of $72.6 trillion across 128,389 funds in 2024. This figure represents approximately 85 percent of the global funds industry, according to the latest IOSCO Investment Funds Statistics Report.

While the overall industry shows growth, the distribution of risk remains uneven. Open-ended funds and closed-ended funds, which constitute the majority of assets, continued to grow. Open-ended funds, in particular, saw a strong rise in net asset value.

Hedge funds, despite their smaller asset share, play a disproportionately important role due to their higher levels of derivatives activity and leverage. This asymmetry means that critical pressure points in the financial system may not be where the bulk of the money is located, but rather where leverage and interconnectedness are most intense.

Industry Expansion and Divergence

The report indicates substantial growth across segments. Open-ended fund assets increased by 15.3 percent to $62.3 trillion in 2024. Qualifying hedge fund assets also climbed, rising 8.2 percent to a record $5.01 trillion.

In contrast, closed-ended fund assets experienced a decline of 3.7 percent, settling at $5.2 trillion. Despite this dip, their value remains significantly higher than in previous decades.

This divergence highlights different growth drivers. Open-ended funds benefit from mainstream market expansion and investor participation. Closed-ended funds, however, are navigating valuation adjustments, reclassifications, and the slower pace of private asset markets.

Policymakers and investors should note this divergence. Public market vehicles remain central to global savings, especially equity and fixed-income funds. However, private market structures, particularly in real estate and private equity, are becoming more embedded.

Regulators must consider the distinct risks associated with different fund types. Liquidity, valuation, transparency, and leverage risks vary significantly between daily-dealing bond funds and private equity vehicles with long lockups and opaque leverage.

Hedge Funds: The System's Sharp Edge

The section on hedge funds warrants close examination. Although smaller in overall asset share, hedge funds concentrate leverage and derivatives usage. In 2024, gross hedge fund leverage stood at 11.9 times net asset value (NAV), an increase from 10.5 times in 2023. Synthetic leverage rose to 8.2 times NAV, and total borrowing increased, bringing financial leverage to 1.42 times NAV.

These figures, while not indicative of immediate crisis, suggest a sector increasingly reliant on borrowed balance sheets and derivative structures. These levels remain below earlier peaks but show a trend of increased leverage.

Hedge fund exposures are heavily concentrated in sovereign bonds, listed equities, reverse repos, and cash. Derivatives exposures are dominated by interest-rate contracts, followed by foreign exchange and equity derivatives. This concentration means that stress in sovereign bond, funding, or rate volatility markets can rapidly transmit through these highly active, leveraged portfolios.

Calmer Majority and Underlying Vulnerabilities

Open-ended and closed-ended funds appear more restrained in comparison. Open-ended funds reported gross leverage of 1.15 times NAV, with aggregate borrowing and financial leverage described as very low. Their portfolios are primarily composed of equities and fixed income, with derivatives used mainly for risk management rather than balance-sheet expansion.

Closed-ended funds also show conservative leverage at the fund level, with gross leverage at 1.15 times NAV and modest derivatives usage. Their portfolios are concentrated in private equity, real estate, and other alternative assets, which naturally have longer holding horizons.

However, low visible leverage should not obscure underlying vulnerabilities. IOSCO notes that some closed-ended fund data may understate true leverage, as private equity structures may not fully capture leverage at the portfolio-company level. This caveat is significant, as leverage increasingly migrates from fund shells into underlying assets or financing structures.

Geographical Concentration of Capital

The report confirms the geographical concentration of global fund activity. The United States leads in open-ended fund assets, with significant contributions from Luxembourg, China, Ireland, and Canada. The US also heavily dominates hedge fund assets.

Closed-ended fund activity is anchored by Luxembourg, Japan, China, the UK, and the US. Allocations generally favour North America and Europe, with Asia-Pacific gaining ground. Africa, however, remains marginal across most fund categories.

Hedge fund geographical allocation to Africa is negligible. Open-ended and closed-ended funds also allocate only a tiny share to the continent. Nigeria makes its first appearance in the closed-ended funds category, with 14 funds and an aggregate NAV of approximately $0.3 billion.

This geographical distribution has implications for emerging markets. Global liquidity is expanding but not naturally flowing to frontier or underserved regions at scale. African governments and capital market operators need to enhance market infrastructure, reporting, legal certainty, FX arrangements, and exit channels to attract global portfolio and private capital.

Recommendations for Governments and Investors

Governments should focus on strengthening surveillance where leverage, derivatives concentration, and bilateral counterparty exposures are highest, rather than imposing blunt rules. IOSCO's findings indicate that bilateral clearing dominates derivatives activity across all fund types.

Policymakers should prioritize improving data quality, collateral transparency, and stress-testing capacity for non-bank finance, particularly in rate, FX, and repo-linked markets. Accelerating reforms to make domestic capital markets investable at scale is also crucial for emerging economies.

Investors are advised to distinguish headline growth from underlying structure. Larger funds are not necessarily safer, and low disclosed leverage may not indicate low embedded risk. Allocators should scrutinize liquidity terms, derivative concentrations, redemption structures, and exposures to volatile markets.

Organized private sector players, including pension funds, insurers, and corporates, have an opportunity to help build deeper local ecosystems. This includes improving issuance pipelines, governance standards, co-investment platforms, and credible vehicles for long-term domestic savings.
