A KSh1 million investment in one of Kenya’s September 2026 Treasury bonds could generate approximately KSh1.55 million in interest over the bond’s remaining life, bringing the total amount received to about KSh2.55 million.
For investors looking for predictable income and a way to put their money to work without actively trading, Kenya’s September 2026 Treasury bond auction presents an interesting opportunity.
The Central Bank of Kenya (CBK) is seeking to raise KSh60 billion for budgetary support through two reopened fixed-coupon Treasury bonds: a 15-year bond and a 30-year bond.
The bonds offer coupon rates of 12.34% and 12.00%, respectively.
And you do not need KSh1 million to participate. Investors can submit non-competitive bids starting from KSh50,000.
September 2026 Treasury Bonds at a Glance
| Bond | Coupon Rate | Remaining Term | Maturity Date | Payment Frequency |
| FXD3/2019/015 | 12.34% | 7.9 years | July 10, 2034 | Semi-annually |
| SDB1/2011/030 | 12.00% | 14.4 years | January 21, 2041 | Semi-annually |
The CBK confirms that Treasury bonds generally provide interest payments every six months, while most fixed-rate Treasury bonds lock in the coupon rate determined at auction for the life of the bond.
What Are the September 2026 Treasury Bonds?
The September auction features two existing Treasury bonds being reopened by the CBK.
The first is FXD3/2019/015, a 15-year Treasury bond originally issued in 2019. It has approximately 7.9 years remaining to maturity and carries a 12.34% coupon rate.
The second is SDB1/2011/030, a 30-year Treasury bond originally issued in 2011. It has approximately 14.4 years remaining to maturity and carries a 12% coupon rate.
Despite the SDB1 designation, the bond is still a fixed-coupon Treasury bond. The different prefix is simply part of the CBK’s issue numbering.

How Much Can KSh1 Million Earn in a Treasury Bond?
This is where the numbers become interesting. For the 12.34% FXD3/2019/015 bond, a KSh1 million investment would generate approximately KSh55,530 every six months after the 10% withholding tax, based on the calculation presented in the video.
That translates to roughly KSh111,060 per year in coupon income.
Over the bond’s remaining life, the estimated total amount received would be approximately KSh1.88 million, including the original KSh1 million investment.
In other words:
KSh1 million invested → approximately KSh880,000 in interest → approximately KSh1.88 million total received.
What about the 12% Treasury bond?
The SDB1/2011/030 bond has a lower coupon rate of 12%, but it has a significantly longer remaining maturity.
Based on the calculations in the video, a KSh1 million investment would generate approximately:
- KSh54,000 every six months after tax
- KSh108,000 per year
- Approximately KSh1.555 million in total interest over the remaining life
- Approximately KSh2.555 million in total receipts, including the original KSh1 million
So, the headline figure is:
KSh1 million → KSh2.555 million total received over the bond’s remaining life.
It is important to distinguish between total receipts and profit. The KSh2.555 million includes the original KSh1 million capital. The estimated gain from interest is approximately KSh1.555 million.
How Much Does KSh50,000 Earn?
You do not need millions of shillings to start investing in Treasury bonds.
The minimum non-competitive bid for the September auction is KSh50,000, while the maximum is KSh50 million.
For the 12.34% bond, KSh50,000 would generate approximately KSh2,777 every six months after tax, based on the video’s calculation.
For the 12% bond, KSh50,000 would generate approximately KSh2,700 every six months after tax.
This illustrates one of the key attractions of Treasury bonds: investors can receive scheduled coupon income without having to actively trade the security.
Why Do Treasury Bonds Pay You Every Six Months?
A Treasury bond is essentially a loan to the government.
When you buy the bond, you are lending money to the government. In return, the government pays you interest, known as a coupon, at predetermined intervals and repays your principal when the bond matures.
This structure is one reason bonds can be useful for investors seeking regular income. Bond investors generally receive coupon payments during the life of the bond, followed by repayment of the principal at maturity.
For Kenya’s Treasury bonds, the CBK says interest is typically paid every six months.
When Can You Invest in the September 2026 Treasury Bonds?
The September Treasury bond sale opened on August 27, 2026, with the deadline for submitting bids set for 10:00 a.m. on September 2, 2026.

Investors can access government securities through the CBK’s DhowCSD platform, as well as through commercial and investment banks acting as custodians.
15-Year vs 30-Year Treasury Bond: Which Is Better?
There is no universally better bond. The right choice depends on your investment objective, time horizon and need for income.
FXD3/2019/015 — 12.34%
Potential advantages:
- Higher coupon rate
- Shorter remaining maturity
- Fewer years before the principal is due back
- Approximately 16 coupon payments remaining
SDB1/2011/030 — 12%
Potential advantages:
- Longer stream of coupon payments
- Approximately 29 coupon payments remaining
- Higher cumulative interest over the remaining life if held to maturity
- Potentially suitable for investors comfortable locking up money for longer
The key trade-off is therefore higher coupon versus longer duration.
A higher total amount received does not automatically make the longer bond the better investment. Investors should also consider how long they can afford to have their money committed.
What Are the Risks of Investing in Treasury Bonds?
Treasury bonds are generally considered lower-risk investments than many corporate or equity investments because they are obligations of the government. However, lower risk does not mean zero risk.
One important consideration is interest-rate risk.
If you sell a fixed-rate bond before maturity, its market price can move depending on prevailing interest rates. Bond prices and yields generally move in opposite directions, meaning changes in market rates can affect the price at which an existing bond trades.
This is why an investor who intends to hold the bond until maturity should think differently from an investor who may need to sell before maturity.
The CBK notes that Treasury bonds are traded on the secondary market, providing investors with an avenue to sell before maturity.
Is KSh2.55 Million Guaranteed?
No. The KSh2.555 million figure is an estimate based on the stated coupon rate, the remaining maturity period and the assumption that the investor holds the bond through maturity and receives all scheduled coupon payments.
It should not be interpreted as a guaranteed investment profit or as a promise that every investor will receive exactly KSh2.555 million.
Investors should also consider inflation, opportunity cost, liquidity needs and the possibility that they may need to sell before maturity.

The Bottom Line
The September 2026 Treasury bond auction gives Kenyan investors two fixed-income options with coupon rates of 12.34% and 12%.
The 15-year bond offers the higher coupon and matures sooner, while the 30-year bond provides a longer stream of coupon payments.
For an investor putting KSh1 million into the 30-year bond, the video’s calculations show approximately KSh1.555 million in interest over the remaining life of the bond, bringing total receipts to about KSh2.555 million.
But the most important lesson is not the headline number.
It is understanding how much income the investment generates, how long your money will be committed, what happens if you need to sell early, and whether the investment fits your financial goals.
As with any investment, do your own research and consider your risk tolerance and liquidity needs before committing your money.
