Introduction and Background

The Central Bank of Kenya (CBK) has been actively involved in developing Kenya's domestic market for government securities since its establishment in 1966. On Feb. 2025, the CBK reopened two infrastructure bonds; bidding for the two papers ran until 12/02/2025. offering investors a chance to invest; it also had 91, 182 & 364 T-bills with a value date of 17th Feb. 2025. Bids received for the two bonds were over 170 billion Ksh and it only accepted 130 billion Ksh.  This act demonstrated how these government assets, which offer a steady and secure return, are a crucial component of conservative investment portfolios.

Data and Analysis

Naming of bonds

Lets say, IFB1/2022/014:

  • IF = Infrastructure bond
  • BI = Beginning of the year
  • 2022 = Bond was issued in 2022
  • 14= Tenor (Period in years)

Calculation of T-bills & T-bonds

The Central Bank provides a yield table in its prospectus for T/bonds and T/bills and users can use the pricing calculator on the CBK website for easy price calculation.

The following is merely a preliminary illustration of how interest is calculated for T-bills and T-bonds:

  1. T-bills:

Face-Value = Ksh 100,000, Discount-rate = 9.5%, Maturity= 91 days

  • Interest = 100,000*(9.5%*91/365) = 2,368.49
  • With-holding-tax= 15%*2,368.49= 355.27
  • Net-interest= 2,368.49 - 355.27= 2,013.22

After 91 days an investor will receive the principal amount(face-value) of 100,000 plus an interest of 2,013.22

  1. T-bonds

Face-Value= Ksh 1,000,000, Coupon-Rate = 10.5%, Maturity = 5 years

  • Semi-annual interest = (1,000,000*10.5%)/2 =52,500
  • With-holding-tax= 15%*52,500= 7,875
  • Net-interest= 52,500-7,875= 44,625
  • Total interest over 5 years= 44,625*5*2= 446,250

After 6 months, an investor will receive Ksh 44,625 and a total of Ksh 446,250 interest for the whole period, plus a principal of Ksh 1,000,000.

Note: The withholding tax on Treasury bonds & bills is 15% for tenors up to 9 years and 10% for tenors 10 years or more, unless tax-exempt investors provide a tax exemption certificate or pay directly to the Kenya Revenue Authority.
