What is a Money Market Fund (MMF)?

A Money Market Fund (MMF) is a type of unit trust that pools money from different investors and invests it in short term, low risk financial instruments such as:

  • Treasury bills (T-bills)

  • Fixed deposits in banks

  • Corporate bonds

  • Commercial paper

MMFs are managed by licensed fund managers who allocate investments to maximize returns while ensuring security and liquidity.

How does a Money Market Fund work in Kenya?

  1. Investment Contributions – Investors put in money into an MMF account which is pooled with money from other investors.

  2. Fund Management – The fund manager invests in low-risk assets such as T-bills, fixed deposits and short-term bonds.

  3. Earnings & Interest Calculation – Interest is accrued daily and compounded periodically (usually monthly).

  4. Withdrawals – Investors can withdraw their money anytime and get the funds within 24 to 48 hours.

How MMF Interest is calculated in Kenya

MMF interest rates are quoted as annualized yields, but they accrue daily. Here is how it works:

  • If an MMF gives a 10% annual return, the daily rate is calculated as:
    10% ÷ 365 = 0.0274% per day

  • If you invest KES 100,000, your earnings per day would be:
    100,000 × 0.0274% = KES 27.40 per day

  • At the end of the month, your balance will grow based on daily compounding.
