One of the most searched questions about Kenyan government securities is also one of the easiest to overcomplicate: how do you actually buy a Treasury Bill? The basic route is through the Central Bank of Kenya’s government-securities system, with DhowCSD providing digital access to your securities account and auction participation.
This guide focuses on the process, not on telling you which tenor to choose. Treasury Bill rates change at auction, and the right maturity depends on when you may need the money.
What is a Treasury Bill?
A Treasury Bill is a short-term Government of Kenya security issued through the Central Bank of Kenya. The standard maturities are 91, 182 and 364 days. Unlike a conventional coupon bond, a T-Bill is issued at a discount and redeemed at face value at maturity. The difference between what you pay and the face value is the return before applicable tax.
That makes the quoted auction percentage useful, but it is not the same thing as receiving that percentage in cash immediately. Your actual cash paid depends on the accepted yield, face value and tax treatment.
Step 1: open or access your CSD account through DhowCSD
Start with the official DhowCSD portal or the official DhowCSD mobile application. Follow CBK’s account-opening and identification requirements. The Central Depository System account is where your government securities are recorded.
Use official CBK channels rather than links sent through social media or messaging groups. You are dealing directly with a government-security platform, so the domain and app publisher matter.
Step 2: decide whether you are making a non-competitive or competitive bid
For most individual investors, the non-competitive bid is the simpler route. CBK states that the minimum face value for a non-competitive Treasury Bill or Treasury Bond bid is KSh50,000, with bids made in KSh50,000 denominations. Under a non-competitive bid, you accept the weighted average rate determined by the auction.
Competitive bidding is designed for larger bids and allows the bidder to specify a desired yield. CBK states a KSh2 million minimum for competitive bids. A competitive bid can be rejected if the requested rate is outside what CBK accepts.
Step 3: choose 91, 182 or 364 days
| Tenor | What it means | Think about |
|---|---|---|
| 91-day | Roughly three months | Shortest lock-up among standard T-Bills |
| 182-day | Roughly six months | Middle ground on maturity |
| 364-day | Roughly one year | Longest standard T-Bill maturity |
Do not choose solely because one tenor has the highest current percentage. The difference between rates can be small, while the difference in how long your money is committed can be large. AMKA’s 91 vs 182 vs 364-day comparison explains that trade-off.
Step 4: submit the bid before the auction closes
Government-security auctions follow the timetable published by CBK. In DhowCSD, select the available Treasury Bill issue, enter the face value you want to bid for, choose the appropriate bid type and submit before the deadline. Recheck the auction details before confirming: tenor, auction date, value date and amount.
A common beginner mistake is to confuse the face value with the exact cash that will leave the bank account. T-Bills are discounted securities, so the amount payable after a successful bid is calculated from the accepted rate and face value.
Step 5: check the auction result and fund the successful bid
After the auction, CBK publishes the results, including the accepted rates. Successful bidders receive payment instructions and must fund the purchase within the required settlement timeline. Missing the payment deadline can cause the allocation to lapse and may have other consequences under CBK rules.
Keep the transaction confirmation and verify that the security appears correctly in your CSD account.
Step 6: maturity
At maturity, the face value is paid according to the account and settlement instructions attached to the CSD account, subject to the applicable tax rules. If you want to invest again, treat that as a new decision rather than assuming every matured T-Bill should automatically be rolled into the next auction.
Treasury Bill or money market fund?
They solve different jobs. A T-Bill has a defined maturity and government-security structure. A money market fund pools investors’ money and normally allows ongoing deposits and redemptions under the fund’s rules. If access to cash is important, compare liquidity before comparing yield.
