An open-ended fund gives investors the right to redeem their interests at their own option, at or before the fund’s termination, and is regulated under the Mutual Funds Act. A closed-ended fund gives investors no such redemption right – capital is returned through distributions or an exit event such as a sale or wind-up – and falls under the Private Funds Act. Both regimes are administered by the Cayman Islands Monetary Authority (CIMA), which classifies a fund by its redemption mechanics rather than its underlying asset class.
The Legal Test: Redemption Rights, Not Asset Type
The Cayman Islands does not classify a fund as open-ended or closed-ended based on what it invests in. It classifies based on whether investors can pull their money out unilaterally.
Under the Mutual Funds Act, a fund is open-ended if investors hold equity interests that are redeemable or repurchaseable at the investor’s option, on notice, before the fund winds up.
Under the Private Funds Act, a fund is closed-ended if no such investor-driven redemption right exists, even if the fund makes periodic distributions. This distinction determines which statute, and which CIMA registration regime, applies.
Which Statute and CIMA Regime Applies
Open-ended funds register or are licensed under the Mutual Funds Act. Meanwhile, closed-ended funds, referred to in the legislation as “private funds”, register under the Private Funds Act. Before that Act came into force, closed-ended structures had no dedicated CIMA registration regime at all; the Private Funds Act created one from scratch.
Separately, and around the same time, the old Mutual Funds Act exemption for open-ended funds with 15 or fewer investors (where a majority could appoint or remove the operator) was also removed. This brought most previously-exempt open-ended funds into CIMA’s registered regime.
Together, these two 2020 changes mean most Cayman funds with more than one investor now register under one regime or the other.
Typical Strategies Attached to Each Structure
Open-ended vehicles suit liquid, actively traded strategies where investors expect periodic exit rights: hedge funds are the classic example.
Closed-ended vehicles suit illiquid, longer-hold strategies where forced early redemption would harm remaining investors: private equity, venture capital, and real estate funds typically use this structure.
The exempted limited partnership (ELP) is the dominant vehicle for closed-ended private funds, though exempted companies, segregated portfolio companies, and unit trusts are used across both regimes.
Different Ongoing Compliance Obligations
Both fund types must file CIMA-approved audited financial statements annually.
But the Private Funds Act layers on closed-ended-specific obligations. These are: periodic, at-least-annual valuation of fund assets; safekeeping and title verification of fund assets; and appointment of a person to monitor the fund’s cash flows and ensure cash is held in accounts in the fund’s name.
These functions can be performed by the fund’s own manager or operator, provided they are independent of portfolio management or any conflicts are identified, managed, and disclosed.
Getting the classification right at formation stage avoids costly restructuring later, since it dictates your CIMA filing regime, audit timeline, and ongoing monitoring obligations.

FAQs
An open-ended fund gives investors the right to redeem their interests at their own option, at or before the fund’s termination, and is regulated under the Mutual Funds Act. A closed-ended fund gives investors no such redemption right – capital is returned through distributions or an exit event such as a sale or wind-up – and falls under the Private Funds Act. Both regimes are administered by the Cayman Islands Monetary Authority (CIMA), which classifies a fund by its redemption mechanics rather than its underlying asset class.
Most do. The Private Funds Act, 2020 brought closed-ended funds under CIMA registration for the first time, and separate 2020 amendments removed the old Mutual Funds Act exemption for open-ended funds with 15 or fewer investors. As a result, nearly all funds with more than one investor must now register under one regime or the other, unless a specific statutory exemption applies.
Yes, but it requires amending the fund’s constitutional documents to grant investors a redemption right, and re-registering under the appropriate CIMA regime, since the classification follows the legal redemption mechanics rather than a fixed label.
Typically yes, because hedge fund strategies rely on liquid, tradeable positions that support periodic investor redemptions, which is why most Cayman Islands hedge funds register under the Mutual Funds Act rather than the Private Funds Act.
Non-compliance can result in CIMA enforcement action, including fines, and can jeopardize the fund’s registration status, which is why closed-ended funds engage an administrator to manage valuation, safekeeping, and cash monitoring obligations on an ongoing basis.
The Cayman Islands Monetary Authority (CIMA) regulates both open-ended funds under the Mutual Funds Act and closed-ended funds under the Private Funds Act, maintaining separate public registers for each.
