Key Takeaways
- • Rising interest rates are forcing investors to confront the structural illiquidity of private market investments, which were attractive during extended periods of low rates but now present distribution and redemption challenges as exit activity slows.
- • Interval and tender offer funds (semi-liquid evergreen structures) have expanded private market access significantly, reaching 308 funds with $233 billion in net assets as of December 2025, up $61 billion year-over-year, but underlying assets remain structurally illiquid despite periodic liquidity features.
- • Slower IPO and M&A activity in a higher-rate environment extends liquidity timelines and delays distributions to investors, creating timing mismatches between capital calls and fund exits.
- • Secondary markets are becoming increasingly important as a liquidity solution for investors seeking to exit or reduce exposure to private market positions.
- • Investors must carefully align private market exposure with their actual liquidity needs and portfolio objectives, particularly given the gap between perceived access (through newer fund structures) and true asset liquidity.
Summary
After years of pursuing yield in private investments during an extended period of low interest rates, sophisticated investors are learning that illiquidity is more than a theoretical constraint. As rates have risen, the structural challenges of private market investments—which offer limited redemption windows and depend on successful exits through IPOs, M&A activity, and secondary sales—have become increasingly material to portfolio management.
Private markets have expanded considerably in recent years, driven by demand from wealth management and retail channels seeking broader access to historically exclusive strategies. Asset managers have responded by launching interval funds, tender offer funds, and other evergreen structures designed to broaden eligibility, lower minimum investments, and incorporate periodic liquidity features. According to VanEck analysis, the interval and tender offer fund market reached a new high of 308 funds with $233 billion in net assets as of December 31, 2025, representing a $61 billion increase from 2024. However, these structural innovations create a critical distinction: while access has expanded through semi-liquid fund wrappers, the underlying private assets themselves remain structurally illiquid.
The interest rate environment has created a secondary challenge. In higher-rate regimes, IPO and M&A activity typically slows, extending liquidity timelines and delaying distributions to underlying investors. This dynamic is particularly acute for investors who underestimated the duration and illiquidity of their private market commitments. The democratization of private equity through retail-accessible structures has introduced a population of investors with shorter time horizons and greater liquidity expectations—a misalignment that creates systemic risks if large-scale redemptions coincide with constrained exit markets.
Secondary markets have emerged as an increasingly important valve for investors seeking to exit or reduce exposure to private market positions before fund maturation. These markets, however, typically operate at discounts to net asset value and require sophisticated execution. Advisors working with institutional and high-net-worth clients are now prioritizing client education on the true liquidity profile of private investments, emphasizing the importance of alignment between portfolio liquidity needs, time horizons, and private market allocation sizing.
