How Kenyan Treasury bonds pay

A Treasury bond pays interest, called the coupon, twice a year until it matures, and then returns the face value. Withholding tax is deducted from each coupon: 15% for bonds with a tenor under 10 years and 10% for bonds of 10 years or more. Infrastructure bonds (IFBs) are tax-free, which is why they are popular with retail investors.

If you buy a bond on the secondary market, you may pay more or less than face value. Paying below 100% adds a gain at maturity; paying above 100% reduces your return.
