The Future of MMFs & Double-Digit Fixed Yields in Kenya
Relationship Manager & Founder of Bengula Inc.
The Job an Emergency Fund Actually Does
Every sound financial plan starts with the same boring, powerful step: an emergency fund of three to six months of living expenses. Its job is not to grow your wealth — it is to stop one bad month (a job loss, a medical bill, a slow quarter for your business) from forcing you to sell a long-term asset or take an expensive loan at the worst possible time.
The mistake most people make is leaving that buffer in a standard savings account paying around 3%. With inflation running higher than that, your "safe" money is quietly losing purchasing power every month.
Why Money Market Funds Fit This Job So Well
A Money Market Fund (MMF) is a regulated collective-investment scheme that pools members' money and lends it short-term to high-quality borrowers — Treasury Bills, fixed deposits, and top-tier corporate paper. You get a share of that interest while keeping near-instant access to your cash.
In Kenya, MMF yields have moved with the Central Bank's rate cycle: when the CBK raises rates, the short-term instruments the fund holds reprice upward, and your yield follows — usually within weeks. The flip side is now playing out. After ten consecutive rate cuts since August 2024, the Central Bank of Kenya held its benchmark rate at 8.75% in April 2026, and average MMF yields have eased from the mid-teens toward 9% to 12% gross in the first half of 2026. The strongest funds — Cytonn, Nabo Africa, and Etica among them — were still posting effective annual rates around 12%.
Where MMF Money Actually Sits (2026 Snapshot)
| Indicator | Figure | Source |
|---|---|---|
| Total CIS assets under management (Sep 2025) | KSh 679.6 billion | CMA / Cytonn |
| Year-on-year growth in CIS AUM | +114.8% | Cytonn Q3'2025 note |
| MMF share of all collective-scheme assets | 58.9% (~KSh 400bn) | Capital FM |
| CBK benchmark rate (Apr 2026) | 8.75% | CBK |
| Typical MMF net yield after 15% WHT | ~8% to 10% | Author estimate |
The headline is the scale of adoption: Kenyans now hold roughly KSh 400 billion in money market funds alone, up from a fund category that barely registered a decade ago. That is real money voting for liquidity plus yield over a dormant savings account.
What Makes an MMF Different From a Bank Account
- Daily compounding, monthly payout: Interest accrues every day and is typically credited monthly, so your buffer is always working.
- Real liquidity: Most funds return your money to M-PESA or your bank within 24 to 48 hours of a withdrawal request.
- Low entry point: Many funds start from as little as KSh 1,000, so it is accessible long before you have "investor" money.
- Withholding tax: A 15% withholding tax applies to the interest, and it is usually deducted at source.
Reading the Headline Rate Correctly
Fund marketing always quotes the gross rate. What lands in your pocket is the net rate after the 15% withholding tax. If a fund advertises 14% per annum gross:
Net yield = 14% × (1 − 0.15) = 11.9% net per annum
That ~11.9% net still comfortably beats a savings account and, in most periods, beats inflation — which is exactly what you want from a buffer.
How to Compare Funds Honestly
- Look at the effective annual yield, not one good day. Daily rates bounce around; the trailing average tells the real story.
- Check liquidity terms. Confirm the actual payout time and any minimum holding period.
- Mind the management fee. It is already baked into the quoted yield, but a high fee drags long-term returns.
- Confirm it is CMA-regulated. Only invest through a fund licensed by the Capital Markets Authority.
Where the MMF Stops and Bonds Begin
An MMF is the right home for money you might need soon — your emergency fund, a business's float, cash waiting to be deployed. It is not designed to lock in today's high rates for years. Once your buffer is full, the next step for longer-horizon capital is usually a Treasury bond or tax-free Infrastructure Bond ladder, which locks a high coupon for the long term while the MMF keeps your liquid reserve productive.
This is exactly why the falling-rate environment matters. As MMF yields drift down with the CBK rate, the case for moving idle, long-horizon cash into longer instruments gets stronger — see Kenyan Treasury Bonds Demystified for how to build that bond ladder, and Sovereign Debt Explained for the mechanics of lending directly to the government.
Used together — MMF for liquidity, bonds for locked long-term yield — you get a simple, powerful cash strategy that most savers never set up.
