The Central Bank of Kenya (CBK) has successfully raised KSh 179.77 billion in a tap sale of two infrastructure bonds, surpassing its initial target of KSh 50 billion. The sale, conducted from August 19–21, 2025, has drawn significant investor interest, indicating a strong appetite for government securities despite market challenges.
Details of the Tap Sale
The tap sale involved the reopening of two infrastructure bonds:
- IFB1/2018/015 (15-year bond due in January 2033)
- IFB1/2022/019 (19-year bond due in January 2041)
The CBK had initially set a target of KSh 50 billion for the tap sale, but the final demand significantly exceeded expectations. The total bids amounted to KSh 207.45 billion, showing an oversubscription. The CBK accepted KSh 179.77 billion worth of bids from the reopening and tap.
Impact of the Bond Issue and Market Context
Significant Investor Demand
This tap sale follows the success of last week’s reopening, where investors placed KSh 323.43 billion against an offer of KSh 90 billion. The CBK accepted KSh 95.01 billion, indicating that investor demand remains strong, particularly for government bonds.
Bond History and Market Context
- IFB1/2018/015: This bond’s tap sale was its first reopening since its primary issuance in January 2018, when the government initially raised KSh 16.48 billion. The tap sale raised KSh 127.98 billion, expanding the bond’s outstanding size more than eightfold.
- IFB1/2022/019: This bond’s tap sale is also its first reopening since February 2022 when it raised KSh 98.38 billion. With the KSh 51.79 billion from the tap sale, the bond’s total outstanding has risen to over KSh 150 billion.
Strategic Purpose of the Tap Sale
The tap sale and reopening reflect the CBK’s strategy to use long-dormant, tax-free bonds to raise significant sums for infrastructure while also mopping up market liquidity. By accepting almost all of the rejected bids from the earlier reopening, the CBK has effectively blurred the line between a traditional tap sale and a full reissue.
Liquidity and Market Impact
With nearly KSh 275 billion now raised across both the reopening and the tap sale, the CBK has significantly expanded its infrastructure bond stock. This could increase secondary market trading, as unallocated funds from the sale may flow into the Nairobi Securities Exchange (NSE), providing liquidity for these long-dated bonds.
Conclusion
The CBK’s tap sale of KSh 179.77 billion in infrastructure bonds has exceeded expectations, reflecting strong investor confidence and the government’s ability to raise funds for infrastructure development. However, the large amount raised in both the reopening and tap sale raises questions about potential market dilution and the future pricing dynamics of the bonds. Despite these concerns, CBK’s strategy to enhance liquidity and expand the government’s infrastructure bond stock is likely to have lasting effects on the Kenyan bond market and investment landscape.
