In short
- A money market fund lends your money short-term; a share makes you part-owner of a business.
- MMF interest is taxed at 15%, deducted by the fund. Dividends on NSE shares are taxed at 5% for residents, and listed shares are exempt from capital gains tax.
- MMF money is back in your account in a few working days. Share money takes a sale plus three business days to settle.
- They are not competitors. One is for money you will need; the other is for money you will not.
Ask around Nairobi and you will hear both: “put it in a money market fund, it pays better than the bank” and “the real money is in shares”. Both are true, about different money.
What each one actually is
A money market fund is a unit trust. You buy units; the fund manager lends the pool short-term — Treasury bills, fixed deposits, high-grade corporate paper — and passes the interest back to you daily, less fees. The fund must be licensed by the Capital Markets Authority.
A share makes you a part-owner of a listed company. You are paid when the company pays a dividend, and the price of your stake moves daily with what others will pay for it. Our guide to buying shares on the NSE covers the mechanics.
Side by side
| Money market fund | NSE shares | |
|---|---|---|
| What you own | Units in a pooled loan book | Part of a company |
| Return | Interest, accrued daily | Dividends, plus or minus price change |
| Can you lose money? | Unlikely but not guaranteed | Yes, and it happens |
| Tax | 15% withholding on interest | 5% on dividends (resident); no CGT on listed shares |
| Ongoing cost | Annual management fee, taken before the quoted yield | Commission on each trade, around 1%–1.5% plus VAT and 0.29% levies |
| Getting your money | Usually a few working days | Sell, then T+3 settlement, then the broker’s payout |
| Minimum | Often KES 100–1,000 to start | One share plus fees, but fees favour larger orders |
| Good for | Emergency fund, saving towards something, cash between investments | Money you can leave alone for years |
The tax, properly
This is where the comparison surprises people.
Money market funds: interest is subject to 15% withholding tax, which the fund deducts before paying you. Read a fund’s factsheet carefully — the headline yield is usually quoted net of the management fee but gross of that 15%, so the number in the advert is not the number in your pocket.
Shares: dividends carry a 5% withholding tax for Kenyan residents, deducted at source, and 15% for non-residents. Gains on shares listed on the NSE are exempt from capital gains tax altogether. Dividends in Kenya has the detail on book closure and payment dates.
So on taxed income alone, a shilling of dividend keeps more than a shilling of MMF interest. That does not make shares better — it makes them different, because the dividend is not guaranteed and the share price can fall.
The risk nobody mentions about MMFs
A money market fund is low-risk, not no-risk. You are lending, and credit can go bad: a fund that reaches for yield by holding weaker corporate paper takes a risk you do not see in the headline rate. Before putting serious money in one, check that the manager is CMA-licensed, read what the fund actually holds, and be sceptical of a yield far above its peers.
The other quiet cost is inflation. A fund paying below the inflation rate is losing you purchasing power slowly, which is comfortable and still a loss.
Where Treasury bills sit
Between the two. A T-bill is a direct loan to the government with a known return and a fixed end date, but it needs a larger minimum and locks the money until maturity. We compared them with shares in Treasury bills vs NSE shares; the same comparison against an MMF comes down to convenience — the fund does the rolling over for you and lets you withdraw whenever you like, and charges you a management fee for doing so.

How most people should use both
- Emergency fund in the MMF. Three to six months of expenses, reachable in days.
- Short-term goals in the MMF. School fees in March, a deposit next year. Money with a date on it has no business in shares.
- Long-term money in shares. Five years and over, where the ups and downs have time to average out.
- The staging post. Save in the fund until you have enough for a sensible share order — see how much you need to start for why small orders are expensive.
Frequently asked questions
Are money market funds taxed in Kenya?
Yes. Interest earned is subject to 15% withholding tax, which the fund deducts before crediting your account.
Which pays more, a money market fund or NSE shares?
Over short periods the fund usually wins, because shares can fall. Over long periods shares have the greater potential, with no guarantee in any given year. They answer different questions.
Can I lose money in a Kenyan money market fund?
It is unlikely but possible. The fund is not a guaranteed deposit; your return depends on what it lends to and on the manager’s credit judgement.
How quickly can I withdraw from a money market fund?
Most funds pay out within a few working days of a withdrawal request. Confirm the stated turnaround with the fund before you rely on it for an emergency.
Should I take money out of my MMF to buy shares?
Only money you will not need for several years. Keep the emergency fund where it is, and move the surplus.
Education, not investment advice. Fund yields and fees change; read the fund’s own factsheet, and check your broker’s charges, before deciding.
