CIMA Fee Increase 2026: What It Did to Umbrella Fund and Segregated Portfolio Economics

The CIMA fee increase 2026 raised the annual registration fee for a registered Cayman mutual fund from CI$3,675 to CI$4,125 and the increment for each segregated portfolio from CI$300 to CI$750, with effect from 1 January 2026. Read as a headline, a 150 per cent rise in the sub-fund increment looks like a deliberate move against umbrella economics. Read against the instruments, it is something narrower. Both the base fee and the per portfolio increment rose by exactly CI$450, so the annual regulatory-fee advantage of a segregated portfolio over a standalone registered fund is unchanged at CI$3,375. Part of the increase also replaced the separate annual return filing fee, which was repealed at the same time. This article sets out the verified figures, models an umbrella of one, three, five and ten portfolios against standalone funds, and states how far the crossover moved.

"When the revised fees were gazetted we saw managers read the sub-fund line in isolation and conclude that the segregated portfolio route had lost its edge. It had not. What changed is the ratio, not the gap. A standalone registered fund now costs CI$3,375 a year more than a portfolio at the regulatory layer, which is the same figure it was in 2025. We would rather a manager model the whole statutory stack for their own number of strategies than react to one line in a fee schedule. The choice between an umbrella and a set of standalone vehicles is rarely decided by CIMA fees alone." David Lloyd, Chief Executive Officer at CV5 Capital

Executive Summary

The 2026 revision changed four numbers that matter to a manager choosing between an umbrella and standalone vehicles, and repealed a fifth. The effect on multi-portfolio economics is smaller and more specific than the percentages suggest.

• The registered fund base fee, the master fund fee, the section 4(4)(a) limited investor fund fee and the per sub-fund increment all rose under Regulations gazetted on 19 December 2025.
• The separate fee for filing the Fund Annual Return was repealed for both mutual funds and private funds, so part of the increase is a consolidation rather than new cost.
• Net of that consolidation, a registered fund, a master fund and a mutual fund segregated portfolio each cost CI$150 a year more than before; a private fund segregated portfolio costs CI$75 more.
• At the regulatory-fee layer, a mutual fund umbrella still beats standalone funds from two portfolios onward, and its annual saving narrowed by CI$450 at every portfolio count.
• A private fund umbrella moved the other way: its saving against standalone private funds widened by CI$225 for every portfolio beyond the second.
• None of this changes a segregated portfolio's regulatory obligations as a sub-fund of a regulated fund.

What Changed on 1 January 2026

Figures in this article are current as at 5 September 2026. The changes were made by four sets of Regulations published in Legislation Gazette No. 55 on 19 December 2025. They are the Mutual Funds (Fees) (Amendment) Regulations, 2025 (SL 68 of 2025) and the Private Funds (Fees) (Amendment) Regulations, 2025 (SL 70 of 2025), with the Annual Returns (Amendment) Regulations for each regime (SL 67 and SL 69 of 2025). CIMA's industry notice of 4 February 2026 confirmed that the revised amounts apply from 1 January 2026. CIMA's notice of 31 December 2025 on Government fee increases described the fund amendments as introducing consolidated annual fees, replacing the requirement to pay both an annual fee at the start of the year and a separate annual return fee later in it.

The mutual fund amendments substitute amounts in the Table of Fees in the Mutual Funds (Fees) Regulations. Item 1 is the annual registration fee for a regulated mutual fund other than a master fund, and item 1A the master fund fee. Item 1F is the fee for a fund registered under section 4(4)(a) of the Mutual Funds Act, the limited investor fund with not more than fifteen investors. Item 4 is the fee for a regulated mutual fund that has sub-funds, expressed as a base amount plus an increment for each sub-fund. The Regulations define sub-fund to include a segregated portfolio of a segregated portfolio company.

CIMA's published fee schedule states the new amounts in United States dollars at its CI$0.82 convention. The base fee is US$5,030.49, the master fund fee US$3,750.00, a mutual fund sub-fund US$914.63 and a private fund segregated portfolio US$640.24. The private fund amendment works differently. It repeals and replaces regulation 4 of the Private Funds (Fees) Regulations, 2024 in full, restating the base fee and each of the three per unit increments.

Why the Sub-Fund Line Overstates the Increase

Until the end of 2025 a regulated mutual fund paid two separate statutory amounts each year. One was the annual registration fee under section 9 of the Mutual Funds Act. The other was the Fund Annual Return filing fee under regulation 3 of the Mutual Funds (Annual Returns) Regulations, set at CI$300 per return by the 2024 amendment. Regulation 2(1) of those Regulations requires a fund with sub-funds to submit a return for each sub-fund, so an umbrella paid the CI$300 filing fee once for every segregated portfolio. The Mutual Funds (Annual Returns) (Amendment) Regulations, 2025 repealed regulation 3 outright.

The same happened on the private fund side. Regulation 4 of the Private Funds (Annual Returns) Regulations, 2021 set the filing fee at CI$300 for the fund and CI$150 for each alternative investment vehicle or sub-fund reported, and the 2025 amendment repealed it. The correct comparison is therefore not CI$300 against CI$750. It is CI$600 against CI$750 for a mutual fund segregated portfolio, and CI$450 against CI$525 for a private fund one.

One transitional point affects 2026 budgets. CIMA's notice states that annual return fees for financial years ending on or before 31 December 2025 continue to be assessed at the pre-revised rates. A fund with a December year end therefore pays the new consolidated annual fee for 2026 and, separately, the old filing fee when its 2025 return is submitted during 2026. That overlap is a one-off. CIMA also stated that the 2026 fee was presented on its portal as a base payment plus an incremental payment, with a single consolidated amount from 1 January 2027.

The Umbrella Model: One, Three, Five and Ten Portfolios

The model below compares two ways of housing the same strategies. In the umbrella case a single segregated portfolio company is the regulated mutual fund, pays one base fee under item 4 and pays the increment for each segregated portfolio. In the standalone case each strategy is its own registered mutual fund under section 4(3) and pays the full base fee. The model covers CIMA annual fees only. It excludes formation costs, directors, administration, audit and every other line that the full cost of launching and running a Cayman hedge fund sets out, because those lines did not change on 1 January 2026.

Two things stand out. The crossover did not move. A manager's own umbrella costs more than a single standalone fund at one portfolio, and less from two portfolios onward, in both years. The umbrella's saving fell by exactly CI$450 at every portfolio count. The saving at N portfolios equals N standalone base fees less one umbrella base fee less N increments. Because the base fee and the increment rose by the same CI$450, the N-dependent terms cancel. The saving was CI$3,375 multiplied by N less CI$3,675; it is now CI$3,375 multiplied by N less CI$4,125.

The one portfolio row describes a manager who forms an umbrella for a single strategy and pays the base fee and one increment. A manager taking a segregated portfolio on an established multi-manager platform is in a different position, because the segregated portfolio company is already registered and the base fee already exists. There the regulatory-layer cost is the increment alone. The full-stack comparison at a single portfolio, including service providers and the AUM at which each route breaks even, is not re-run here. The standalone digital asset fund versus segregated portfolio model and the platform versus standalone comparison for conventional strategies already do that work.

The Marginal Portfolio: The Number That Did Not Move

For a manager deciding whether the next strategy becomes a new segregated portfolio or a new standalone fund, the relevant figure is the marginal annual regulatory cost of each route. In 2025 that was CI$300 against CI$3,675, a ratio of more than twelve to one. In 2026 it is CI$750 against CI$4,125, a ratio of five and a half to one. As a gap rather than a ratio, the standalone route cost CI$3,375 a year more in both years.

The percentage framing is not irrelevant, since the statutory component of the platform side rose by more in proportion. But the statutory layer is a small part of either budget. Administration, audit and directors dominate the annual run rate of a standalone fund, and those are the lines an umbrella shares across portfolios. Launching multiple funds under one regulated platform deals with that sharing in operational terms.

The master fund line matters where the standalone alternative is a master-feeder. That pair pays the registered fund fee for the feeder and the master fund fee for the master, CI$7,200 in 2026 against CI$6,300 in 2025. Where an umbrella portfolio would replace a master-feeder pair, the 2026 increase added CI$900 to the standalone side of the comparison rather than CI$450.

Private Fund Umbrellas Moved the Other Way

The private fund amendment did not mirror the mutual fund one. The base fee rose by the same CI$450, but the per segregated portfolio increment rose by CI$225. That asymmetry runs in the umbrella's favour for closed-ended strategies housed in a segregated portfolio company registered under the Private Funds Act.

The marginal comparison for a private fund portfolio is CI$525 against CI$4,125, a gap of CI$3,600, up from CI$3,375 in 2025. The umbrella saving at N portfolios therefore widens by CI$225 for each portfolio, offset once by the CI$450 rise in the base fee. The two effects cancel at two portfolios and the umbrella is better off from three portfolios onward. Which regime applies is a question of redeemability rather than choice, as the comparison of the Mutual Funds Act and Private Funds Act regimes explains, so a manager cannot select the more favourable increment. The point is that a structure housing both open-ended and closed-ended portfolios now carries two different increments, and a budget that applies one figure to both will be wrong.

What the Increase Did Not Change

A fee model misleads if it is read as a model of obligations. A segregated portfolio is a sub-fund of a regulated fund, and the 2026 revision left every obligation attached to that status where it was. Regulation 2(1) of the Mutual Funds (Annual Returns) Regulations still requires a return for each sub-fund within six months of the financial year end, submitted through the fund's auditor. The audit requirement under section 8 of the Mutual Funds Act, the offering document requirements, the anti-money laundering framework, the corporate governance rules and CIMA's supervisory powers all apply to the umbrella and, through it, to each portfolio. The Fund Annual Return and what CIMA requires sets out the filing mechanics in detail.

The payment mechanics are also unchanged in law. Section 9 of the Mutual Funds Act and section 10 of the Private Funds Act require the annual fee on or before 15 January each year. Where it is unpaid, an additional fee of one twelfth of the annual fee accrues for each month or part of a month it remains outstanding, and CIMA may waive that additional fee for good cause. For the 2026 transition CIMA announced that penalties would not be assessed on the unpaid incremental increase until after 15 February 2026, later extended to 15 March 2026. The pre-revised amount remained subject to penalties from 15 January. That relief was specific to the first year and should not be assumed for 2027.

Nor did the increase alter how statutory segregation works. Ring-fencing between portfolios arises under the Companies Act, not the fee regulations, and its strength depends on the operational discipline described in the complete guide to the Cayman segregated portfolio company. Paying CI$750 rather than CI$300 for a portfolio buys nothing additional. The comparison in this article is a cost comparison only.

How to Model It in a Launch Budget

Treat CIMA fees as a fixed statutory layer and model it separately from the service provider layer and the manager's own costs. That separation makes fee revisions easy to absorb and exposes the real question, which is how the provider layer scales with the number of portfolios.

• Count the portfolios honestly. Include every strategy expected within the first two years, because the umbrella saving is a function of portfolio count.
• Apply the correct increment. CI$750 for a mutual fund sub-fund and CI$525 for a private fund segregated portfolio, plus one base fee of CI$4,125 for the umbrella itself.
• Price the standalone alternative properly. Use CI$4,125 per registered fund, and CI$7,200 where the strategy would otherwise need a master-feeder pair.
• Budget the 2026 overlap. A fund with a 2025 financial year still pays the old filing fee on that return during 2026, in addition to the consolidated annual fee.
• Convert at CIMA's published rate. The fee schedule uses CI$0.82 to US$1, so a US dollar budget should use the schedule's own figures.
• Then move to the layer that decides it. Administration, audit, directors and registered office costs per portfolio are where an umbrella's economics are made or lost.

For a manager on a multi-manager platform, the statutory layer is simpler still. The segregated portfolio company is the registrant and pays one base fee for the whole structure, so the regulatory-layer cost attributable to any single portfolio is the increment. How the base fee and shared provider costs are allocated between portfolios is a commercial question for each platform and outside the scope of this article.

Common Mistakes

• Comparing CI$300 with CI$750 without adding back the repealed CI$300 filing fee, and so overstating the net rise in the cost of a mutual fund portfolio by a factor of three.
• Treating the private fund increment as CI$750. It is CI$525, and applying the wrong figure to closed-ended portfolios overstates the umbrella's cost.
• Reading the ratio rather than the gap, and concluding that a segregated portfolio's advantage over a standalone fund halved when in absolute terms it did not move.

Key Takeaways

• Rebuild any 2026 budget using CI$4,125 for a registered fund, CI$3,075 for a master fund, CI$750 per mutual fund sub-fund and CI$525 per private fund segregated portfolio.
• Remove the separate annual return filing fee from 2026 onward, but keep it in the 2026 budget for the 2025 financial year return.
• Keep the CI$3,375 marginal gap between a segregated portfolio and a standalone registered fund as the working number for open-ended strategies; it did not change.
• For an umbrella you own, expect the annual saving against standalone funds to be CI$450 lower than a 2025 model showed, with the crossover still at two portfolios.
• For closed-ended portfolios under the Private Funds Act, expect the umbrella saving to be higher than in 2025 from three portfolios onward.
• Treat the statutory layer as fixed and decide the structure on the provider layer, where the per portfolio economics actually vary.

Frequently Asked Questions

What are the CIMA annual fees for mutual funds in 2026?

From 1 January 2026 the annual registration fee for a regulated mutual fund is CI$4,125, the master fund fee is CI$3,075, and a fund with sub-funds pays CI$4,125 plus CI$750 for each sub-fund. The amounts were substituted into the Table of Fees by the Mutual Funds (Fees) (Amendment) Regulations, 2025. CIMA's fee schedule states the US dollar equivalents at CI$0.82 to US$1.

What is the CIMA fee for a segregated portfolio in 2026?

For a segregated portfolio company registered as a mutual fund, the increment is CI$750 for each segregated portfolio, up from CI$300. For a segregated portfolio company registered as a private fund, the increment is CI$525 per segregated portfolio. In both cases the umbrella also pays a single base fee of CI$4,125.

Did the 2026 fee increase remove the FAR filing fee?

Yes. The Mutual Funds (Annual Returns) (Amendment) Regulations, 2025 and the Private Funds (Annual Returns) (Amendment) Regulations, 2025 repealed the separate fee for submitting the annual return. CIMA has stated that returns for financial years ending on or before 31 December 2025 are still assessed at the pre-revised rates, so the filing fee is still payable on a 2025 return submitted during 2026.

Is a Cayman umbrella fund still cheaper than standalone funds after the fee increase?

At the CIMA fee layer, yes, from two portfolios onward under both the Mutual Funds Act and the Private Funds Act. The annual saving for a mutual fund umbrella is CI$450 lower than under the 2025 fees at every portfolio count, while the saving for a private fund umbrella is higher from three portfolios. The provider layer, which the statutory fees do not cover, usually decides the question.

When are CIMA annual fund fees due and what happens if they are late?

The annual fee is due on or before 15 January each year under section 9 of the Mutual Funds Act and section 10 of the Private Funds Act. If unpaid, an additional fee of one twelfth of the annual fee accrues for each month or part of a month outstanding, which CIMA may waive for good cause. For 2026 only, CIMA deferred penalties on the incremental increase until after 15 March 2026.

Does a higher sub-fund fee mean a segregated portfolio has more regulatory obligations?

No. The fee revision changed amounts, not obligations. A segregated portfolio remains a sub-fund of a regulated fund, with an annual return required for each sub-fund, an audited financial statement requirement at fund level, and the offering document, anti-money laundering and governance rules applying through the umbrella. The comparison between an umbrella and standalone funds on fees is a cost comparison only.
