Semiliquid investment vehicles—including interval funds, tender-offer funds, nontraded REITs, and nontraded BDCs—are becoming a significant bridge between public and private markets, offering investors periodic liquidity and access to traditionally illiquid asset classes. 

These vehicles have grown rapidly, with U.S.-based semiliquid assets reaching $344 billion by the end of 2024, driven primarily by demand for private credit strategies that generate consistent income without necessitating frequent redemptions. However, their appeal comes with steep costs: average expense ratios exceed 3%, far above the fees of mutual funds and ETFs, and many carry layered management, incentive, and acquired fund fees that create high performance hurdles for investors. 

Leverage plays a substantial role in returns, particularly in credit-focused funds, where income appears more attributable to borrowed capital than superior asset selection. Semiliquid private equity vehicles, on the other hand, have largely underperformed, often failing to match the S&P 500. 

Finsum: These structures expand access to private markets, but investors must weigh the benefits of income and diversification against liquidity constraints.
