Interval Funds: Private Markets in a Public Wrapper, and the Fine Print

For most of history the best private investments, private equity, private credit, real assets, were walled off from ordinary investors. You had to be wealthy enough to qualify and willing to lock capital away for a decade, with the messy partnership tax paperwork on top. A new kind of fund has been quietly taking that wall apart, and it is worth understanding for what it opens up and for the fine print it tends to skate past.

Interval funds, and their close cousins, wrap private, illiquid assets inside a structure that looks and behaves a lot like a mutual fund. They bring real private-market exposure to investors who could never reach it before. That is a genuine and valuable development. It also repackages the illiquidity rather than removing it, and the gap between access and true liquidity is exactly where uninformed buyers get hurt.

What An Interval Fund Is

An interval fund is a registered investment fund, regulated like a mutual fund, that holds assets which are themselves illiquid: stakes in private companies, private loans, real estate, other things that cannot be sold on a moment's notice. To square illiquid holdings with a fund ordinary investors can own, it offers liquidity on a schedule. At set intervals, quarterly is common, the fund offers to buy back a limited amount of investor shares at the current value.

That periodic buyback is the defining feature, and where the name comes from. You are not locked in for ten years the way you would be in a traditional private fund. You also cannot sell whenever you like the way you can with a public stock. You get windows. Between them your money stays put. It sits in the middle ground between the total illiquidity of private funds and the daily liquidity of public ones, and that middle ground is exactly what makes it useful and easy to misjudge.
