Managing Illiquidity in Open-Ended Funds with Private Asset Allocations: Challenges and Solutions

This article examines how open-ended funds can incorporate private assets, while preserving liquidity. Private assets can enhance diversification and returns, but long lock-ups, asynchronous capital calls and distributions, and appraisal-based valuation complicate their integration into liquid vehicles. Using benchmark indices, we document outperformance consistent with an illiquidity premium and discuss how valuation lag and smoothing affect measured risk, especially in crisis periods. We then present a dynamic recommitment framework that stabilizes capital at work, limits cash drag, and improves the translation of fund-level IRRs into realized portfolio returns, while a liquid public asset sleeve absorbs cash flows and redemptions. Stress tests show how allocations drift in crises and under large outflows, and how suspending future commitments can rebalance the portfolio without forced secondary sales. Finally, we discuss ramp-up policies that accelerate convergence to target private allocations, while limiting overshoot.
