Money Market Fund vs Fixed Deposit vs T-Bill: Where Should Kenyans Save in 2026?
Top Kenyan money market funds returned 11-13% in early 2026, T-bills track the 9% CBR, and fixed deposits sit in between. We compare liquidity, returns, tax and risk so you park your cash in the right place.
Kenyans have never had more ways to earn a real return on idle cash — and never been more confused about which is best. Money market funds, fixed deposits and Treasury bills all promise to grow your savings safely, but they differ sharply on access, minimums and after-tax return. Here is the 2026 comparison, in plain shillings.
The three options at a glance
| Feature | Money Market Fund | Treasury Bill | Fixed Deposit |
|---|---|---|---|
| Typical 2026 yield | ~11–13% p.a. | ~8–10% p.a. | ~7–10% p.a. |
| Minimum | ~KES 1,000 | KES 100,000 | Varies (often KES 20,000+) |
| Access to cash | 1–3 days, anytime | At maturity (91/182/364 days) | At end of term |
| Interest paid | Daily, compounding | Upfront (bought at a discount) | At maturity |
| Withholding tax | 15% | 15% | 15% |
| Risk | Very low (diversified) | Lowest (government) | Low (bank) |
Money market funds: flexibility wins
An MMF pools your money with thousands of other savers and lends it short-term to banks and the government. You can start with as little as KES 1,000, interest accrues daily, and you can withdraw within a few working days. For an emergency fund or any cash you might need soon, the liquidity is hard to beat.
Treasury bills: the government’s IOU
T-bills are short-term loans to the Government of Kenya, sold at a discount and redeemed at full face value — the difference is your interest. They are the safest shilling instrument available, but the KES 100,000 minimum and fixed 91/182/364-day lock make them better for lump sums you can set aside.

Fixed deposits: simple but rigid
A fixed deposit locks a sum with your bank for a set term at a guaranteed rate. It is simple and predictable, but in 2026 most banks pay less than a good MMF, and breaking the deposit early usually forfeits interest. Use one only when you are certain you will not touch the money.

There is no single winner — there is a right tool for each job. Keep your emergency cash in a money market fund for instant access, lock lump sums you will not need into Treasury bills for the safest return, and use fixed deposits only when a guaranteed rate suits.
