Quick answer: A money market fund (MMF) pools savers’ money and invests it in short-term, low-risk instruments such as treasury bills, bank deposits and commercial paper. You can usually start with a small amount, top up by M-Pesa, earn interest daily and withdraw within a few working days. Choose a fund approved by the Capital Markets Authority (CMA), compare the net yield after fees, and remember interest is taxed and rates change.
How a Money Market Fund Works
- You buy units in the fund (often with a low minimum).
- The fund manager invests in short-term, low-risk securities.
- Interest is calculated daily and usually added monthly (compounding).
- You withdraw by request; money reaches you in a few working days.
How to Compare MMFs
| Factor | What to check |
|---|---|
| Approval | Fund manager and scheme approved by the CMA |
| Net yield | Yield after management fees; compare like with like |
| Fees | Management fee, any entry or exit charges |
| Withdrawal time | How many working days to receive money |
| Minimums | Opening amount and top-ups |
| Track record | How long the fund has run and how steady the yield has been |
Advertised yields change with interest rates; past yields do not guarantee future returns.
KES vs Dollar MMFs
| KES fund | USD fund | |
|---|---|---|
| Currency | Shillings | US dollars |
| Good for | Emergency fund, short-term savings | Dollar earners, saving for dollar costs |
| Risk | Inflation | Exchange rate moves when you convert |
Tax
Interest from money market funds is subject to withholding tax, deducted by the fund. Check the current rate in the fund’s statement and terms.
Risks
- MMFs are low-risk but not guaranteed like a fixed deposit.
- Yields fall when interest rates fall.
- Withdrawals take a few days, so keep a little cash for emergencies.
- Fake "funds" promising very high fixed returns are scams; check CMA approval.
How to Start
- Pick 2–3 CMA-approved funds and compare net yield, fees and withdrawal time.
- Open an account online with your ID and KRA PIN.
- Make a first deposit by M-Pesa or bank.
- Set a monthly standing order or reminder to top up.

Example: An Emergency Fund
A teacher saves KSh 3,000 a month into a KES money market fund by M-Pesa on payday. After a year she has three months of expenses saved, earning interest, and withdraws part of it when her phone breaks instead of taking a mobile loan.
Your First 30 Days
- Week 1: decide the goal (emergency fund, school fees, deposit).
- Week 2: compare 3 CMA-approved MMFs.
- Week 3: open an account and make the first deposit.
- Week 4: set an automatic monthly top-up.
Common Mistakes to Avoid
- Choosing only by the highest advertised yield.
- Investing money you need tomorrow.
- Ignoring fees and withdrawal time.
- Trusting unapproved "funds" with guaranteed high returns.
