AMKA comparison of money market funds and Treasury Bills in Kenya
Quick answer: choose by when you need the money, not by the biggest percentage alone. In our dated snapshot, a secondary MMF comparison listed a leading 11.11% gross yield on 29 October 2026. The latest completed CBK auction result available to AMKA was dated 26 October 2026: 8.7478% for 91 days, 8.8591% for 182 days and 9.0267% for 364 days. MMF yields can change; a T-Bill is bought at a discount for a defined maturity.

Rates are dated, not promises. The MMF figure is a secondary comparison benchmark and should be checked against the fund manager's own current factsheet. CBK auction results are the primary source for Treasury Bills.

Why the percentages are not apples to apples

An MMF reports a variable annual yield. CMA explains that collective investment scheme performance fluctuates and that MMF yield is calculated daily. A Treasury Bill is sold below face value and redeemed at face value on its maturity date. The auction rate helps determine the price you pay; it is not a monthly interest credit.

KSh100,000 worked example

MMF illustration: KSh100,000 × 11.11% = KSh11,110 gross annual mathematical growth if that yield stayed unchanged for a full year. It is an illustration, not a forecast.

Treasury Bill illustration: CBK's 26 October result published prices per KSh100 of face value. A KSh100,000 face-value bid therefore implies:

For an emergency fund

Access comes first. Do not lock away money you may need before maturity. An MMF can be more flexible, but “open-ended” does not mean every provider pays instantly. Keep the first layer of emergency cash genuinely accessible and read our Kenya emergency-fund guide.
