What Is an Interval Fund?

Updated July 9, 2026 6 min read

Most funds let an investor sell whenever they want, with money typically available within a few days. An interval fund works differently on purpose, trading away that everyday flexibility for the ability to hold investments that don’t trade easily.

The short answer

An interval fund is a type of closed-end fund that periodically offers to buy back, or repurchase, a limited portion of its outstanding shares — commonly on a quarterly basis, though the schedule varies by fund. Unlike a typical mutual fund, investors generally can’t redeem shares whenever they choose; they can only submit redemption requests during these specific repurchase windows, and even then, the fund isn’t obligated to buy back every share that’s offered.

Why this structure exists

Interval funds are typically built to hold assets that don’t trade easily or quickly on public markets — think real estate, private credit, or other less liquid investment types. A fund holding illiquid assets can run into trouble if it has to sell them on short notice to meet a wave of investor redemptions, potentially at a poor price and to the detriment of remaining shareholders. By limiting redemptions to scheduled intervals, the fund gains time to manage its own liquidity needs, which in turn makes it more feasible to hold assets that wouldn’t be practical in a fund offering daily redemptions.

How the repurchase process works

How this differs from ETFs and typical mutual funds

A simplified illustration

Suppose an interval fund holds a portfolio of real estate-related assets and offers quarterly repurchases of up to 10 percent of outstanding shares. An investor wanting to sell would need to wait for one of those quarterly windows and might only get part of their request fulfilled if many other investors request redemptions at the same time. This is a hypothetical illustration of the general mechanic, not a description of any specific fund.

What to weigh

The core trade-off with an interval fund is liquidity for access: giving up the ability to sell on demand in exchange for the potential to invest in asset types not typically available through daily-traded funds. That trade-off means understanding the fund’s specific repurchase schedule, its historical repurchase percentages, its expense ratio, and how comfortable an investor is with money being less readily accessible are all important considerations before investing.
