Alternative investments have historically been accessible only to institutional investors or those willing to lock up capital for a decade or more.
Interval funds have changed this equation.
Interval funds combine SEC registration, periodic liquidity windows, and the ability to hold illiquid assets. They sit at a practical midpoint between a mutual fund and a private equity fund.
This post covers what an interval fund is, how it works, who it suits, the risks advisors must understand, and what due diligence looks like before recommending one.
An interval fund is a closed-end investment company registered under the Investment Company Act of 1940. It is designed to hold illiquid or alternative assets that standard mutual funds cannot access, while offering investors periodic opportunities to exit rather than locking up capital indefinitely.
Six defining characteristics, per FINRA:
Interval funds do not trade on a securities exchange or other secondary market. Investors cannot sell their shares at any time. Shares are repurchased by the fund at set intervals, typically quarterly, though some funds operate on six-month or annual cycles.
The repurchase offer ranges from 5% to 25% of the fund’s assets per interval. Investors can purchase shares daily at NAV, similar to an open-end mutual fund. The fund is not subject to the 15% illiquid asset cap that applies to standard mutual funds.
The result is a structure that gives individual investors access to alternative asset classes previously limited to high net worth individuals, hedge funds, and institutional investors, with a guaranteed but limited liquidity window at each interval.
Understanding the mechanics is essential before recommending an interval fund to any client.
At each repurchase interval, the fund offers to buy back a set percentage of its shares at NAV. That percentage is fixed in the fund’s prospectus and ranges from 5% to 25% of fund assets.
If total redemption requests from all investors exceed that percentage, each investor receives a pro-rata allocation. A client who requests a full exit may only receive partial redemption at that interval and must wait for the next window for the remainder.
The NAV at which shares are redeemed is not known at the time the investor accepts the repurchase offer. The exact price is determined on a specified date after acceptance. This creates pricing uncertainty that does not exist in daily-liquidity mutual funds or exchange-traded securities.
Unlike exchange-listed closed-end funds, interval fund shares cannot be sold on a secondary market between repurchase windows. Once a client invests, exit is only available through the fund's periodic repurchase process.
The fund must notify investors of upcoming repurchase offers in advance. Advisors managing interval fund positions should track these notification windows and ensure clients understand the timeline.

Interval funds are designed to hold assets that standard mutual funds cannot. Because they are not subject to the 15% illiquid asset cap that applies to open-end mutual funds, they can allocate the majority of their portfolio to illiquid strategies.
Asset categories confirmed by FINRA:
Private credit and business loans. Real estate and real estate securities. Private equity and hedge fund strategies. Farmland and forestry. Catastrophe bonds. Infrastructure assets.
These categories share two common characteristics. They are difficult to value daily, which is why interval funds do not offer daily redemption. They carry an illiquidity premium, meaning investors accept limited liquidity in exchange for the potential for higher returns than comparable liquid assets.
Before recommending any interval fund, advisors should read the fund’s prospectus to understand specifically what it holds. The category label alone is not sufficient. Two interval funds, both described as private credit funds, may have meaningfully different underlying asset quality, duration profiles, and concentration levels.
Interval funds address a genuine gap in the product landscape available to advisory clients who do not qualify for private fund investments.
The primary value proposition is access. Private credit, farmland, infrastructure, and catastrophe bonds were previously available only to institutional investors and high-net-worth individuals who could meet minimum investment thresholds for private funds. Interval funds make these exposures available in smaller, more accessible allocations.
Investors in illiquid assets have historically earned a return premium over comparable liquid investments in exchange for accepting the liquidity constraint. Interval funds are designed to capture this premium within a registered investment vehicle.
Private credit, real estate, and infrastructure returns are generally less correlated with public equity and bond markets than standard portfolio allocations. Adding interval fund exposure can reduce portfolio-level volatility during periods when public markets move sharply.
Unlike fully locked-up private equity or venture capital funds, interval funds guarantee a liquidity opportunity at each repurchase interval. The liquidity is limited, but it is not absent. This is a meaningful structural advantage over fully illiquid alternatives.
Advisors can build interval fund positions incrementally, purchasing shares daily at NAV without the timing constraints of private fund capital calls.
Each risk below is structural. It cannot be mitigated through manager selection or market timing. Advisors must assess each against the specific client’s situation before recommending an interval fund.
Clients cannot exit an interval fund between repurchase windows regardless of market conditions, personal financial needs, or portfolio changes. A client who needs liquidity between intervals has no exit mechanism.
If total redemption requests at a given interval exceed the fund’s repurchase offer percentage, clients receive only a partial exit. The remainder of the position stays invested until the next interval. Clients who need a full exit within a single cycle may not be able to achieve one.
The redemption price is not known when the client accepts the repurchase offer. The NAV is determined on a specified later date. The price received may differ from the price expected at the time of the decision.
Per FINRA, interval fund fees and expenses tend to be higher than those of other closed-end funds and mutual funds.
Fee structures typically include management fees, service fees, potential front-end sales charges, and repurchase fees charged to cover the administrative costs of periodic redemption processing.
Interval funds often carry relatively high stated distribution rates. Per FINRA, the distribution amount may include a return of capital rather than solely income or gains. Return of capital distributions reduces the client’s cost basis, which affects tax treatment.
Advisors should verify the composition of a fund’s distributions before presenting its distribution rate as a yield equivalent.
The underlying assets of interval funds, particularly private credit, catastrophe bonds, and infrastructure, require specialized underwriting expertise.
Advisors recommending interval funds based on category labels without reviewing the prospectus and understanding the underlying portfolio are taking on due diligence liability.
This is the section FINRA and Schwab explainers do not cover in depth. For advisors, suitability is where the regulatory and fiduciary obligation becomes concrete.
The client’s time horizon must accommodate the fund’s repurchase cycle and the possibility of pro-rata exits. A client who may need capital within six to twelve months is not a suitable candidate for a quarterly-interval fund where full exit may take multiple cycles.
The client’s risk profile must reflect the potential for delayed exit at an adverse NAV. A client with low risk composure who reacts to market volatility by wanting to liquidate positions immediately is structurally unsuited to interval fund ownership. There is no mechanism to act on that impulse between repurchase windows.
Interval funds should complement a portfolio, not anchor it. No single interval fund or category of interval fund should represent a concentration that creates a liquidity problem at the household level. The concentration risk compounds in scenarios where multiple positions become illiquid simultaneously.
Interval funds are registered under the Investment Company Act of 1940 and file Form N-2 with the SEC. They are not exempt from securities laws. They are not unregistered private funds. This distinction matters for compliance documentation and client disclosure.
Before recommending any interval fund, advisors should confirm the following from the fund’s prospectus and most recent shareholder report:
This is the advisor-specific angle that generic explainers leave unaddressed, and it is where StratiFi's role in the conversation becomes practical.
Standard portfolio risk scores are built on liquid, exchange-traded assets with daily pricing. When a client portfolio includes a meaningful allocation to interval funds, those positions are priced at NAV on the fund’s schedule, not daily market pricing.
A risk score that averages interval fund exposure into the portfolio calculation without accounting for the liquidity constraint and valuation methodology produces an inaccurate picture of actual portfolio risk.
Concentration risk in interval fund positions is harder to monitor than concentration in publicly traded securities.
A client can accumulate meaningful exposure across multiple interval funds in the same category, for example, two private credit funds and a real estate interval fund, without any single position triggering a concentration alert.
The exposure at the strategy level may be significant even when individual positions appear modest.
StratiFi’s PRISM risk model provides multi-factor analysis that captures actual portfolio risk, including alternative asset exposure. ComplianceIQ monitors concentration risk and suitability alignment at the account level, which is directly relevant when interval funds are added to client portfolios.
When an interval fund position is added to a client portfolio, the suitability rationale must be documented. The documentation must address time horizon, risk tolerance, liquidity needs, and concentration at the household level. When the fund’s NAV or distribution composition changes materially, the ongoing suitability of the position must be reviewed and the review documented.
A compliance monitoring system that does not flag illiquid positions for periodic suitability review leaves this documentation gap open. ComplianceIQ surfaces these positions for supervisory review automatically.

Interval funds give advisors a practical route to alternative asset exposure for clients who are not eligible or ready for fully locked-up private vehicles.
The tradeoff is real: limited liquidity, higher fees, NAV uncertainty, and complexity that requires genuine due diligence before recommending.
The advisors who use interval funds well treat them as a complement to the core portfolio, assess suitability rigorously at the client level, and maintain documentation that connects the position to the client’s documented risk profile and time horizon.

An interval fund is a closed-end investment company registered under the Investment Company Act of 1940 that holds illiquid or alternative assets and offers investors periodic opportunities to redeem shares at NAV, typically quarterly, rather than providing daily liquidity.
Open-end mutual funds offer daily liquidity at NAV and are subject to a 15% cap on illiquid assets. Interval funds do not offer daily redemption, are not subject to the 15% illiquid asset cap, and are designed specifically to hold alternative assets such as private credit, real estate, and infrastructure.
Interval funds are illiquid between repurchase windows. Exit is available only at set intervals, typically quarterly, and only for the percentage of fund assets the fund offers to repurchase, which ranges from 5% to 25% per interval. If redemption requests exceed that percentage, investors receive a pro-rata allocation and may not achieve a full exit in a single cycle.
Interval funds commonly invest in private credit and business loans, real estate and real estate securities, private equity and hedge fund strategies, farmland and forestry, catastrophe bonds, and infrastructure assets. They are not subject to the 15% illiquid asset cap that applies to standard mutual funds.
The primary risks include illiquidity between repurchase windows, pro-rata redemption when requests exceed the repurchase offer, NAV price uncertainty at redemption, higher fees than standard mutual funds, distribution rates that may include return of capital, and the complexity of the underlying asset categories.
Redemption is only available at the fund’s set repurchase intervals, most commonly quarterly. Some funds operate on six-month or annual cycles. The fund’s prospectus specifies the repurchase schedule and the percentage of shares the fund will offer to repurchase at each interval.
Interval funds can be suitable for retail investors with long time horizons, adequate liquidity from other sources, and risk tolerance that accommodates potential delayed exit. They are not suitable for investors who may need access to capital between repurchase windows or who have short-term liquidity requirements.
Interval fund fees typically include management fees, service fees, potential front-end sales charges, and repurchase fees charged to cover the administrative costs of periodic redemption processing. Per FINRA, interval fund fees tend to be higher than those of other closed-end funds and mutual funds.
