Kenya’s August infrastructure-bond reopening attracted KSh460.40 billion of bids against KSh150 billion offered, equivalent to about 307% demand. CBK accepted KSh312.03 billion, including KSh193.89 billion of net new borrowing after KSh118.14 billion of redemptions.
The three bonds produced average accepted yields of 12.1960%, 12.6877% and 13.0520%. CBK’s prospectus states that the securities do not attract withholding tax.

Kenya Infrastructure Bonds Draw Record KSh460B in Bids
Kenyan investors offered the Central Bank of Kenya more than three times the amount it initially sought in August’s reopening of three infrastructure bonds.
The Kenyan Wall Street auction-results analysis reports KSh460.40 billion of bids against KSh150 billion offered. CBK accepted KSh312.03 billion, about 67.8% of bids received and more than twice the original offer. The publication describes both total bids and acceptances as records within the Treasury-bond auction series it reviewed.
After KSh118.14 billion is applied to redemptions, KSh193.89 billion represents net new borrowing. KSh460.4 billion was demand, not money raised.
How Demand Was Split
Demand was strong across all three securities:
- IFB1/2019/016: KSh166.22bn bid, KSh112.64bn accepted, 12.1960% average yield.
- IFB1/2021/018: KSh154.90bn bid, KSh105.54bn accepted, 12.6877% average yield.
- IFB1/2021/021: KSh139.28bn bid, KSh93.85bn accepted, 13.0520% average yield.
The official CBK August infrastructure-bond prospectus shows coupons of 11.750%, 12.667% and 12.737%, with final maturities in October 2035, March 2039 and August 2042.
Why Were Investors So Interested?
Tax treatment is one attraction.
CBK’s prospectus marks withholding tax as N/A and explicitly says the bonds do not attract withholding tax.
That increases the value of the income relative to a taxable investment offering the same headline return. Investors should still compare investments based on their own tax position and after-fee returns.
The demand also signals substantial liquidity seeking long-term government cash flows. Pension funds, insurers, banks and individuals use bonds differently, but this auction shows significant capital was willing to lock into yields around 12%–13%.
Coupon, Yield and Price Are Different
This auction shows why coupon and yield should not be treated as the same number.
The coupon is the fixed interest rate attached to the bond. The accepted yield reflects the return investors required at reopening, based on the price paid and remaining cash flows.
The CBK official infrastructure-bond pricing tables also show accrued interest payable on each reopened security. Near the accepted yields, clean prices can sit below KSh100 per KSh100 face value, while the dirty settlement price rises above KSh100 after accrued interest is added.
So “above par” needs care: the cash paid at settlement can exceed KSh100 even when the underlying clean bond price is below par.

The Bonds Are Also Amortising
Another important feature is easy to miss.
The prospectus shows 50% amortisation before final maturity: October 2030 for IFB1/2019/016, April 2030 for IFB1/2021/018 and September 2031 for IFB1/2021/021.
Half of principal is therefore scheduled to be returned before the final 2035–2042 maturity dates.
Investors should examine the actual cash-flow schedule instead of treating each security as a simple bond whose entire principal remains outstanding until final maturity.
What Could Happen in Secondary Trading?
Settlement and secondary trading begin on August 17, according to the prospectus.
Strong primary demand can support secondary pricing, but it does not guarantee price gains.
Bond prices remain sensitive to inflation, CBK policy expectations, government borrowing requirements and changes in market yields.
If market yields rise after purchase, existing bond prices generally fall. That price risk remains even when the interest income does not attract withholding tax.
Kenya’s infrastructure-bond auction shows KSh150 billion offered, KSh460.40 billion bid and KSh312.03 billion accepted. Three columns show average accepted yields of 12.1960%, 12.6877% and 13.0520%, followed by an explainer showing coupon, yield and purchase price as different concepts.
What Investors Should Watch
After August 17, investors should monitor:
- Secondary-market prices and yields;
- Premiums or discounts after settlement;
- Changes in Kenya’s yield curve;
- Future government borrowing volumes; and
- Inflation and monetary-policy expectations.
The Business Today August auction coverage similarly places accepted yields between 12.20% and 13.05%, reinforcing the scale of investor demand across the three maturities.
Conclusion
The August reopening demonstrates how strong demand for Kenya’s infrastructure bonds remains.
Investors submitted KSh460.40 billion against KSh150 billion offered, while CBK accepted KSh312.03 billion. The longest bond cleared at an average accepted yield of 13.0520%.
But oversubscription is only part of the lesson.
For investors, the auction highlights the importance of comparing coupon, yield, clean price, accrued interest, tax treatment and cash-flow timing before judging a Treasury bond’s return.
FAQs
1. Did the government raise KSh460.4 billion?
No. KSh460.40 billion was the total amount investors offered through their bids. CBK actually accepted KSh312.03 billion. After accounting for approximately KSh118.14 billion of redemptions, the net new borrowing from the transaction was about KSh193.89 billion.
2. Are the infrastructure bonds tax-free?
The official CBK prospectus specifically states that the three securities do not attract withholding tax and lists withholding tax as N/A. That improves their after-tax income appeal, but investors should avoid interpreting this as meaning every possible personal or institutional tax consequence automatically disappears.
3. Why is the accepted yield different from the coupon?
The coupon is fixed as a percentage of the bond’s face value, while yield considers the price an investor pays and the remaining cash flows. Because reopened bonds can trade above or below their original face value, their market yield can differ materially from their coupon rate.
4. When can the reopened bonds begin trading?
The CBK prospectus sets settlement for Monday, August 17, 2026, with secondary trading also commencing that day in multiples of KSh50,000. Investors can therefore begin watching market prices and yields after settlement to see how the exceptional primary-auction demand translates into secondary-market pricing.
