What is a money market fund?
A money market fund pools investor cash and invests it in short-term, lower-risk instruments such as Treasury bills, fixed deposits and near-cash securities. The fund publishes an annualized yield, while your balance usually earns interest daily and credits income periodically depending on the fund manager.
Why invest in an MMF?
- Liquidity is usually better than a fixed deposit because withdrawals are commonly processed within a few business days.
- Minimum balances are often accessible for retail investors.
- Returns usually track short-term interest rates more closely than ordinary savings accounts.
- Fund assets are held separately from the fund manager through a custodian structure.
How to compare top funds
Start with the net yield because that is closer to what you keep after withholding tax. Then compare the manager, withdrawal process, minimum balance, fees, customer support and how consistently the fund publishes rates. For a current sorted view, use the MMF rankings page and the performance overview.
Tax on MMF returns in Kenya
MMF interest is generally quoted gross before tax and net after Kenya's 15% withholding tax on interest. Real Time Rates shows both values where available, but investment decisions should compare the net annual yield.
How to open an MMF account in Kenya
Once you have picked a fund, the process is mostly paperwork and typically takes a few days to activate:
- Choose your fund — compare net yields and redemption speed on the rankings page.
- Prepare KYC documents — national ID or passport, KRA PIN, a passport photo, and the M-PESA number or bank account for payouts.
- Apply — most managers accept applications through their app or online portal; some still use a printable form.
- Fund the account — send at least the minimum initial amount (commonly KES 100-5,000) via M-PESA paybill or bank transfer; units are allocated at the next dealing price.
- Track and top up — the manager publishes the daily yield; you can deposit more any time and redeem when you need the cash.
Frequently asked questions
- How much do I need to invest in a money market fund in Kenya?
- Most Kenyan MMFs accept an initial investment of KES 100-5,000 depending on the manager, with top-ups from as little as KES 100 via M-PESA or bank transfer. Check the fund's current minimum before applying.
- How long does an MMF investment take to mature?
- MMFs have no maturity date. Your balance earns the daily yield from the day units are allocated, and you can redeem any business day — withdrawals typically settle within 2-4 business days.
- Are money market funds in Kenya safe?
- MMFs are regulated by the Capital Markets Authority and must hold assets with a separate custodian, but they are not deposit-insured like bank accounts. Yield is variable and capital is technically at risk; losses have been rare historically.
- How is MMF interest taxed in Kenya?
- Interest from Kenyan MMFs is subject to a 15% withholding tax for resident individuals, deducted at source as a final tax. Compare funds using the net yield, which reflects what you actually keep.
