How money market funds work in Kenya — and how safe they really are (2026)

Money market funds (MMFs) have become Kenya's default answer to "where do I put savings I might need soon?" — better returns than a bank savings account, daily interest, and M-Pesa withdrawals. This guide explains what an MMF actually is, where the money goes, and what protects it.

What a money market fund is

An MMF is a unit trust: your money is pooled with other investors' and invested in low-risk, short-term instruments — mainly Treasury bills, bank fixed deposits and top-rated commercial paper. You own units of the pool; interest accrues daily and is usually reinvested.

It is not a bank account. Returns are not fixed or guaranteed — the yield moves with market interest rates. (For current yields, see our comparison — each figure there is dated and sourced — see our savings & money market fund comparison.)

The three-party structure that protects you

A CMA-regulated fund is deliberately split so no one company holds all the power over your money:

1. The fund manager (CMA-licensed) makes investment decisions.
2. The trustee ensures the fund is run per the trust deed and the law.
3. The custodian (a bank) actually holds the assets.

The practical effect: the fund manager cannot walk away with the money — it never sits in the manager's own accounts. If the manager collapsed, the assets remain with the custodian under the trustee's oversight.

What can still go wrong

• Yields fall when market rates fall — last year's rate is not a promise.

• Credit events: if a bank or issuer the fund lent to defaults, the fund bears the loss. Check the fact sheet for how much sits in a single institution.

• Withdrawal timing: most funds pay out within a few business days, though some offer faster M-Pesa withdrawals for smaller amounts.

• No KDIC cover: deposit insurance protects bank deposits. An MMF's protection is the structure above, not a guarantee fund.

How to judge a fund (beyond the headline yield)

1. Licence: the manager appears on the CMA's register of licensed collective investment schemes and fund managers at licensees.cma.or.ke — check it before you invest.
2. Effective yield vs management fee — compare net returns.
3. Fact sheet transparency: where the money is invested, and how concentrated it is.
4. Minimums and withdrawal terms that fit how you'll actually use it.

Tax

Interest earned in an MMF is subject to withholding tax of 15%, deducted at source as a final tax — the fund takes it off before crediting your interest, so the yield you compare should already be net of it.

Frequently asked questions

Can I lose money in an MMF? Losses are rare because the assets are short-term and high-grade, but yields fall with rates, and issuer defaults are possible. It's low-risk, not no-risk.

MMF or SACCO or bank account? Different tools: see our comparison of MMFs, SACCOs and bank savings.

How do I start? Most funds onboard via an app or M-Pesa paybill with a low minimum initial investment and small top-ups.
