Analysis: what the non-competitive share actually shows
The 31/08/2026 Treasury bill auction is the clearest read on how much of this channel is being used. Against Kshs. 28,000.00 million offered across the three tenors, bids of 56,735.22 million came in, a performance rate of 202.63 percent, and 44,321.90 million was accepted. Of that, 25,711.79 million was competitive and 18,610.11 million non-competitive. On the 364-day bill the non-competitive share was larger than the competitive one, 4,762.79 million against 1,396.69 million, on total accepted of 6,159.48 million.
That number is not a retail headcount, and it should not be read as one. Non-competitive bidding is defined by bid type, not by investor size, and the announcement exempts state corporations, public universities and semi-autonomous government agencies from the Kshs. 50 Million per investor account per tenor cap that otherwise applies to non-competitive bids. Institutions that simply want the average rate use the same door. What the split does establish is that a large block of demand arrives without a yield view attached, and that the Central Bank’s own distribution channel, rather than a dealer network, is where that demand is aggregated.
The pricing context matters too. Accepted rates in that auction moved almost not at all from the previous week, 8.7692 percent against 8.7700 on the 91-day, 8.9400 against 8.9480 on the 182-day, and 9.0323 against 9.0356 on the 364-day. In a market that stable, a non-competitive bidder gives up very little by not naming a price. In a repricing week the same bidder takes whatever the auction produces, which is the trade the rules make explicit.
The direction of policy is set out in the 2026 Medium Term Debt Management Strategy, which lists domestic retail digital bonds via mobile money among the innovative financing options the government will explore, and names continued use of DhowCSD as one of the reforms intended to deepen the domestic market and diversify the investor base. What the documents do not yet show is a published count of retail CSD accounts or a broken-out retail share of holdings. A reader tracking whether the phone channel is widening the investor base rather than moving existing money would look for that disclosure, and for any change in the 50,000 shilling minimum, which is the single number that decides who can use the channel at all.
What the documents say
Buying government debt usually means opening a brokerage account, signing custody paperwork and wiring money from a bank. Kenya has taken most of that chain out. The Central Bank of Kenya, acting as fiscal agent for the Republic of Kenya, runs its own securities register and lets a saver bid into a Treasury bill or bond auction from a phone. The published rules set out exactly how far that goes, where it stops, and what it costs.
The register sits at the central bank, not at a broker
The Central Bank has established an electronic register, a Central Securities Depository, which accounts for ownership of the securities. Once payment takes place the register is updated at the Central Bank and statements are made available to account holders through the CBK DhowCSD platform. Participation in an auction is open to all categories of investor provided they hold an active CSD account at the Central Bank. Individuals may open those accounts on their own or jointly; corporate entities include companies, co-operatives and other societies, insurance companies, banks, non-bank financial institutions, NGOs and bodies established by statute.
The important line in the auction rules is about who charges what. An investor may open a CSD account directly with the Central Bank, where no fee is charged, or open a client account through an authorised custodial institution, including commercial banks and investment banks, which may charge a maintenance fee. That is the fee layer a mobile channel removes. The rules then split bid submission by investor type: commercial banks and investment banks bid for their own book and for client accounts through the DhowCSD graphical user interface, while retail investors submit through the DhowCSD investor portal, available as a mobile app or a web platform, or through Treasury Mobile Direct.
What it costs to get through the door
The published minimums are the real gate. In the Treasury bill auction dated 31/08/2026, individual bids had to be a minimum face value of Kshs. 50,000.00 for non-competitive bids and 2,000,000.00 for competitive bids, and only investors with active CSD accounts were eligible. The same split appears in bond prospectuses. The re-opened infrastructure bonds IFB1/2019/016, IFB1/2021/018 and IFB1/2021/021, offered for KES 150 billion with settlement on Monday, 17-Aug-2026, set the non-competitive band at a minimum of KES 50,000.00 and a maximum of KES 50,000,000.00, with competitive bids starting at 2 million per CSD account per tenor.
So the phone removes the intermediary, not the ticket price. A saver who cannot put up fifty thousand shillings is outside the auction whatever device they hold. What the small bidder does get is a price they did not have to work out. Non-competitive bids are allotted at the weighted average rate at the cut-off determined in the auction, and all non-competitive bids are accepted in full. Competitive bids are ranked by yield from lowest to highest, and those above the cut-off rate are rejected. The retail bidder is spared the guess, and gives up the chance of a better yield in exchange.
Getting paid, rolling over, and getting out
Settlement still runs on conventional payment plumbing. In the bill auction, payments had to be made by electronic transfer using RTGS and reach the Central Bank no later than 2.00 p.m on Monday 7th September, 2026, quoting the CSD account number, the amount payable and a payment key obtained from the DhowCSD investor portal under the transactions tab. Investors who do not honour payment for successful bids are barred from investing in government securities for a period prescribed by the Bank, and the bill announcement repeats that defaulters may be suspended.
Two features matter more than they look. Maturing securities held in a CSD account, along with amortisations and coupon payments, may be rolled over into new securities by activating the netting flag on DhowCSD, in which case payment for successful bids is processed automatically and any refund goes to the investor’s commercial bank account. That turns a series of auctions into something closer to a standing order. And the exit is defined: if a holder needs to redeem before maturity and cannot find a buyer in the secondary market, the Central Bank will buy the security back as a last resort at 3% above the higher of the prevailing market yield or the coupon rate. Secondary trading in the August infrastructure bonds was to commence on Monday, August 17, 2026, in multiples of KES 50,000.00.
