MMF vs Bonds in Kenya:
Which Gives Better Returns?
A data-driven comparison of yield, liquidity, tax treatment and risk — with a clear recommendation for each investor type.
📌 Short Answer
- Infrastructure Bonds (IFBs) win on yield + tax — up to 17.5% TAX-FREE
- MMFs win on liquidity — access your money in 24 hours vs months for bonds
- For long-term savings: IFB Bonds. For active/emergency funds: MMF
- Combining both is the optimal strategy for most Kenyan investors
The Core Difference
An MMF gives you daily liquidity — your money is essentially like a high-yield savings account. A bond locks your money for 2–7 years but pays a fixed (often higher) rate. The right choice depends entirely on when you'll need the money and how much tax you pay.
💰 Money Market Fund
- •Yield: 14–18% gross (11.9–15.3% net)
- •Tax: 15% WHT deducted at source
- •Liquidity: T+1 (within 24 hours)
- •Minimum: KES 100–5,000
- •Duration: No lock-in
- •Best for: Emergency fund, parking cash
🏛 Infrastructure Bond (IFB)
- •Yield: 17–18% gross — TAX FREE
- •Tax: 0% WHT (tax-exempt)
- •Liquidity: NSE secondary market only
- •Minimum: KES 3,000
- •Duration: 5–25 years coupon, tradeable
- •Best for: Long-term wealth building
The Tax Advantage of Infrastructure Bonds
This is where bonds become dramatically more attractive — especially for higher-income investors. IFBs are exempt from Withholding Tax under the Income Tax Act. This means:
KES 1,000,000 invested for 5 years
| MMF (17.5% gross) | IFB Bond (17.5% gross) | |
|---|---|---|
| Gross Annual Return | KES 175,000 | KES 175,000 |
| Tax (15% WHT) | − KES 26,250 | KES 0 ✓ |
| Net Annual Return | KES 148,750 | KES 175,000 |
| 5-Year Compounded | KES 2,059,000 | KES 2,192,000 |
| Tax Alpha | — | + KES 133,000 more |
Who Should Choose What
Emergency Fund / Saving for a goal < 1 year
You need access to your money without penalty. An MMF returning 15% net is far better than a savings account.
Long-term wealth building (3+ years)
Tax-free compounding over 5+ years creates significantly more wealth. Lock away money you won't need.
The optimal strategy
Keep emergency/active money in an MMF. Allocate long-term savings to IFBs for maximum after-tax return.
