Key takeaway: The Co-op Money Market Fund is a CMA-regulated unit trust managed by Co-op Trust Investment Services Limited. Official product pages put the minimum entry at KSh 100. Mid-to-late September 2026 industry trackers put the gross effective annual yield near 7.9%–8.0% (about 6.7%–6.8% after 15% withholding tax). Its published management fee of 0.90% p.a. is among the lowest in Kenya. Rates change. Confirm the live figure with Co-op Trust before you invest.
Co-op’s money market fund is built for capital preservation, emergency money and short parking of cash, not for chasing the highest headline yield in Kenya. It sits in the middle-to-lower half of the 2026 yield table, but stands out on cost and a low official entry point.

What the Co-op Money Market Fund Is
The Co-op Money Market Fund is part of the Co-op Unit Trust, managed by Co-op Trust Investment Services Limited, linked to the Co-operative Bank of Kenya group.
It pools money from individuals, chamas, SMEs, corporates and institutions into high-quality short-term instruments. Co-op Trust lists government securities, bank deposits, Treasury bills and corporate paper among the holdings it targets.
Older fund fact sheets describe a money-market style portfolio with an average maturity under 18 months, built around deposits, Treasury paper and related instruments. The aim is income and capital preservation, with enough liquidity for redemptions, not equity growth.
Co-operative Bank’s unit-trust page and related product notes list practical features: no fixed minimum investment period, access to funds within three days after notice, account updates within 24 working hours, and interest calculated daily and credited monthly.
Current Interest Rates and Yields (2026)
Yields are not fixed. They move with Treasury bill rates, bank placement rates and the fund’s portfolio.
Recent independent trackers (gross effective annual yield, before 15% WHT):
- About 7.9% (7 September 2026 table, Co-op MMF at 7.9% gross / 6.70% net)
- About 8.0% (18 September 2026 Business Daily–based table)
- About 8.04% gross / 6.83% net (Serrari ranking as of 29 September 2026)
Those are snapshots. They are not Co-op Trust’s private guarantee for the year ahead. Gross yields are usually published after management costs are already reflected in the unit price. Net is what remains after the standard 15% withholding tax on interest for typical resident individuals.
Illustrative only: on KSh 100,000 at 8.0% gross for a full year, interest would be about KSh 8,000 before tax and about KSh 6,800 after 15% WHT, if the rate held for twelve months. Rates do not sit still for a full year.
Always confirm the live daily or effective annual yield with Co-op Trust Investment Services or a current fact sheet before you invest.
Fees
Independent September 2026 trackers list the Co-op Money Market Fund management fee at 0.90% per annum. Serrari notes that as the lowest management fee among the Kenyan money market funds it tracks.
A lower fee does not automatically mean a higher net return than every peer. Portfolio yield, expenses and timing still matter. It does mean less of the fund’s income is taken as a headline management charge relative to many funds that charge around 2% p.a.
Confirm whether any trustee, custody or other costs sit inside a total expense figure on the latest fact sheet. Do not assume 0.90% is the only cost line forever.
Minimums, Liquidity and Tax
- Start: KSh 100 on the official Co-op Trust unit-trust product page. Some Co-op Bank materials historically said “no minimum deposits.” Some trackers list KSh 500. Confirm when you open.
- Top-ups: Described as flexible and convenient on the product page.
- Lock-in: No minimum investment period stated in Co-op’s standard MMF feature list.
- Withdrawals: Co-op materials say you receive funds within three days of notice. Plan for business days, not same-second M-Pesa cash-out like some super-app products.
- Tax: Interest attracts 15% withholding tax for typical resident investors, usually treated as a final tax on the interest portion.
Unit trusts are not KDIC-insured bank deposits. Capital preservation is the mandate. It is not the same as a guaranteed deposit under deposit insurance.
How to Invest in the Co-op Money Market Fund (2026)
Co-op’s documented joining route is form-based and KYC-led, then funding by transfer, cheque or M-Pesa to the collection details on the joining pack.
1. Confirm the manager is licensed
Check Co-op Trust Investment Services / the Co-op Unit Trust against the Capital Markets Authority register before you send money.
2. Gather KYC
Typical individual pack: national ID or passport, KRA PIN, passport photo, phone number, and bank details for redemptions. Chamas and companies need group or board documents and signatory mandates.
3. Complete the joining and risk-profiling form
Co-operative Bank’s unit-trust page says complete the joining and individual risk-profiling form, then submit KYC. Co-op Trust’s site also offers a contact form for account opening interest.
4. Fund the account
Send the initial deposit to the collection account or M-Pesa instructions on the joining form. Co-op states funding is through cheques, money transfers or M-Pesa. Use your client or portfolio reference exactly as instructed so the cash posts to the right account.
5. Branch and digital channels
Many investors open through Co-operative Bank branches and Co-op Trust client service. If the Co-op Bank mobile app shows an Invest or Unit Trust menu for your profile, use only the flow that names the Co-op Money Market Fund and issues a clear portfolio number. Do not treat every “Invest” button as proof the product is live for your account until you receive confirmation.
6. After opening
- Keep your portfolio number and welcome documents.
- Top up regularly if that is your plan.
- Watch statements and published yields.
- Request redemptions with enough notice for the three-day window.
Contacts listed by Co-op Trust materials include:
- Co-operative House, 5th Floor, Haile Selassie Avenue, Nairobi
- P.O. Box 48231-00100, Nairobi
- Email: co-optrust@co-opbank.co.ke / co-optrustclientservice@co-opbank.co.ke
- Call centre lines published on Co-op Trust channels, including 0711 049 000 and related numbers
Use the contacts on the current Co-op Trust or Co-op Bank page if any line has changed.
Who It Suits
Often a fit if you want:
- a low official entry point (KSh 100 on the product page)
- a bank-group unit trust with a low published management fee
- emergency or short-term savings without a fixed lock-in
- interest calculated daily and credited monthly
Often a weaker fit if you want:
- the highest MMF yield in Kenya this week (leaders have recently quoted about 11% gross)
- instant full liquidity every day
- long-term equity or hard-currency returns
Compare yield, fee, fund size, redemption experience and disclosure. Do not pick on yield alone.
Risks and Points to Watch
- Yields fall when short-term market rates fall.
- Credit risk still exists in deposits and paper inside the portfolio.
- Redemptions can be delayed or, in rare stressed cases, restricted under the fund rules. Fact sheets warn redemption rights may be suspended in certain circumstances.
- Incomplete KYC delays opening and withdrawals.
- Group money should sit in a proper chama or corporate account, not one member’s personal fund by accident.
Read the information memorandum and latest fact sheet. Past performance is not a guide to future returns.

Bottom Line
The Co-op Money Market Fund is a practical, low-entry CMA unit trust for parking cash and building an emergency float. Official materials put the start point at KSh 100, with no lock-in period and redemptions framed around three days’ notice. September 2026 trackers show gross yields near 8% and a standout 0.90% management fee, not a top-of-table yield. Open only through Co-op Trust’s documented process, fund carefully, and treat every rate as live data.
