Ample Cash Met Exceptional Bond Demand and Funded a Much Larger Government Borrowing Week

Executive summary

Kenya's rates market ended the week calm at the short end and exceptionally busy at the long end. The Central Bank of Kenya kept its policy rate at 8.75%. Banks held average excess reserves of KSh17.8 billion, while the overnight interbank benchmark stayed close to the policy rate. Cash was available and the central bank continued active liquidity operations. [1] [3]

Treasury-bill yields barely moved. Demand improved, led by the 91-day bill and a recovery in the 364-day bill. The bigger event was the infrastructure-bond auction. Investors submitted KSh460.4 billion of bids and Treasury accepted KSh312.0 billion across three reopened bonds. This was a clear demand for long-term, tax-exempt income, but it also gave the government room to borrow far more than the advertised amount. [1] [4] [5]

After the maturities stated in the auction results, the two auctions implied roughly KSh204.6 billion of additional borrowing. That figure describes accepted commitments, not cash already settled by the report cut-off. The assessment is therefore mixed. Strong liquidity and improving private credit are positive, but the main risk is that repeated large government issues absorb cash that could otherwise fund households and businesses. The next test is how money-market conditions respond after settlement. [3] [4] [5] [6]

What this means to investors

Short-term savers still receive a positive return after a simple inflation adjustment. The 91-day bill cleared at 8.7734% and the 364-day bill at 9.0365%, while July inflation was about 6.5%. That leaves a rough inflation-adjusted gap of about 2.3 to 2.5 percentage points before tax, fees and changes in future inflation. It is an illustration, not a guaranteed real return. [3] [4]

A KSh100,000 face-value 91-day bill at the auction's average price cost about KSh97,859.50 and pays KSh100,000 at maturity. The KSh2,140.50 difference is the gross discount before tax. The annualised yield should not be mistaken for the cash earned over only 91 days. [4]

Long-term investors accepted yields from 12.1960% to 13.0520% on the reopened infrastructure bonds. Coupon is the interest rate written on a bond. Yield is the return implied by the price paid. The bonds' coupons ranged from 11.7500% to 12.7370%, and the prospectus recorded no withholding tax on their interest. Their long maturities create greater price sensitivity when market yields change. [5] [6]

Existing bondholders generally benefit when market yields fall because fixed cash flows become more valuable and bond prices tend to rise. New buyers face the opposite trade-off: locking in income can reduce reinvestment risk, but the market price can fall if inflation or government borrowing pushes yields higher. [1]

Borrowers have received some relief. Average bank lending rates fell to 14.3% in July, and private-sector credit grew 10.2% from a year earlier. This confirms that lower rates are beginning to reach the private sector. Continued improvement is not guaranteed if large government auctions repeatedly absorb bank and fund-manager liquidity. [3]

Market at a glance

Latest figures available by the cut-off. Previous positions use the immediately comparable official observation.

WHAT THIS TELLS US Short-term conditions were steady: the policy rate, overnight rate and bank reserves barely changed. Bill yields also stayed close to 9%. The lower infrastructure-bond yields reflect strong demand and tax treatment, but they should not be compared mechanically with July's taxable fixed-rate bonds.

Accepted Treasury-bill rates and the policy-rate anchor

Figure 1. Accepted Treasury-bill rates and the policy-rate anchor, 26 February-13 August 2026.

WHAT THIS TELLS US The latest week did not start a broad fall in short-term rates. Bill yields rose substantially from March through June, then levelled off. The 91-day yield eased in the latest auction, but the 364-day yield moved slightly higher.

What changed this week?

• 1The central bank paused at 8.75%. The Monetary Policy Committee held the Central Bank Rate on 11 August. Inflation remained inside the target range, but oil and food risks argued against an immediate cut. The decision kept the overnight market anchored while the Bank watched whether previous easing continued to lower lending rates. [3]

• 1Bank liquidity remained comfortable. Excess reserves averaged KSh17.8 billion, little changed from KSh17.7 billion in the previous week. KESONIA was 8.7482% on 13 August, almost exactly aligned with the policy rate. Average interbank trading increased to KSh18.8 billion from KSh13.4 billion, with 25 deals a day rather than 21. More trading did not signal stress because the price of overnight cash stayed stable. [1] [2] [7]

• 1Treasury-bill demand strengthened without a broad yield fall. Investors bid KSh40.79 billion for KSh28.0 billion offered. Treasury accepted KSh37.02 billion. The 91-day bill drew the strongest short-term demand, while the 182-day bill was undersubscribed. Accepted yields moved by less than four basis points. One basis point is one-hundredth of a percentage point. [4]

• 1Long-bond demand changed the scale of borrowing. The three infrastructure bonds drew KSh460.4 billion of bids against KSh150.0 billion offered. Treasury accepted KSh312.0 billion and left about KSh148.4 billion of bids unaccepted. Strong demand therefore did not mean every price was accepted. Official results recorded KSh118.1 billion of redemptions and KSh193.9 billion of net new borrowing. [5]

• 1Secondary trading rose, but it did not prove an inflow. Domestic secondary bond turnover increased 27.59% to KSh48.65 billion during the week. This confirms more trading, not new capital. Every secondary buyer had a seller. The bulletin's published domestic yield curve was dated 7 August, so the evidence did not confirm a full curve repricing through 14 August. [1]

Why did it happen?

First, liquidity and policy were stable. Banks had cash above reserve requirements, and overnight rates stayed at the policy anchor. Investors did not need a large liquidity premium for short maturities. [1] [7]

Second, the infrastructure bonds offered scarce long, tax-exempt income. The three securities mature between 2035 and 2042 and amortise half their principal in 2030 or 2031. That structure attracted investors seeking long cash flows and some earlier principal repayment. [6]

Third, redemptions supplied reinvestment demand. The bond result recorded KSh118.1 billion of maturities. Investors receiving principal needed somewhere to place it, which likely supported the auction. The data do not identify how much each investor group reinvested. [5]

Fourth, Treasury used the demand to front-load funding. Acceptance exceeded the advertised bond amount by KSh162.0 billion. This improved the government's near-term cash position, but it also increased the amount of domestic liquidity committed to public debt. [5]

Auction watch: where did investors want their money?

WHAT THIS TELLS US Investor preference was not simply short-term or long-term. Demand formed a barbell: the shortest bill was popular, while the long infrastructure bonds attracted the largest commitment. The middle bill was weaker. One auction is not enough to call this a permanent preference.

Bids received as a share of the amount offered

Figure 2. Bids received as a share of the amount offered, auctions announced by 14 August 2026.

WHAT THIS TELLS US The infrastructure-bond auction was the clear outlier. Within bills, investors favoured the 91-day instrument, while the 182-day offer did not reach full subscription. Demand was therefore strong but uneven across maturity.

Who benefits and who faces pressure?

WHAT THIS TELLS US Current liquidity is strong enough to support both public borrowing and improving private credit. The trade-off becomes harder if government repeatedly accepts amounts far above plan or if settlement drains bank reserves and pushes overnight rates above the policy rate.

Where is money moving?

Confirmed auction data show KSh37.02 billion accepted in Treasury bills and KSh312.03 billion accepted in infrastructure bonds. The combined commitment was KSh349.05 billion. Scheduled maturities totalled KSh144.40 billion, leaving approximate net new borrowing of KSh204.65 billion before other government cash movements. [4] [5]

The timing matters. Both the bill and bond cash settlements were due on 17 August. At the report cut-off, the allocations were confirmed but the cash had not yet moved. The analysis therefore describes committed capital, not completed settlement. [4] [6]

Official holder data as at 7 August show financial corporations owned 80.0% of government securities. Commercial banks held 35.5%, pension funds 14.4%, insurers 14.1%, households 6.2% and non-residents 4.2%. Those figures identify the broad investor base, but the auction results do not reveal which groups placed the latest bids. [1]

Non-competitive accounts received KSh19.72 billion of bills and KSh143.99 billion of bonds. Non-competitive bidding does not prove retail participation because qualifying institutions can also use it. Rising secondary turnover likewise does not prove a net inflow. [4] [5] [1]

Accepted allocations, stated maturities and approximate net new borrowing

Figure 3. Accepted allocations, stated maturities and approximate net new borrowing.

WHAT THIS TELLS US The week's funding increase came overwhelmingly from the infrastructure bonds. The calculation is reliable as an auction measure, but it is not a complete government cash-flow statement and should not be treated as settled financing before 17 August.

What could change this view?

Base case. Over the next one to four weeks, KESONIA remains near 8.75%, bill yields stay close to 9%, and demand for government securities remains firm. Private credit continues to improve, but the pace may slow if large public issues continue. [1] [3]

Positive possibility. Lower oil and food pressure allows inflation to ease, Treasury accepts amounts closer to plan, and the 17 August settlements pass without a liquidity squeeze. Lower market yields would support existing bond prices and could allow lending rates to fall further. [3] [6]

Negative possibility. Higher inflation, repeated over-borrowing or a sharp fall in excess reserves pushes KESONIA above the policy rate. Investors then demand higher auction yields, bond prices weaken and banks become more selective with private borrowers. [1] [3]

Evidence that would strengthen the view. Excess reserves remain near or above the current level after settlement; KESONIA stays within about 0.10 percentage point of the policy rate; and bill auctions remain fully subscribed without a material rise in accepted yields.

Evidence that would weaken the view. Excess reserves fall sharply for several days; KESONIA moves persistently above the policy rate; bill or bond auctions fall below full subscription; or private-credit growth and lending-rate improvement reverse.

What to watch next

Only schedules that were public by 14 August 2026 are included.

WHAT THIS TELLS US The first test comes before the next policy meeting. Settlement and the following bill auction will show whether current liquidity can absorb heavy government financing without lifting overnight rates or bill yields.

Final Desk takeaway

Kenya's money market was liquid, and short-term rates were stable rather than clearly falling. Investors strongly preferred the 91-day bill within the bill auction, while the largest commitment went to long infrastructure bonds. This allowed government to accept far more borrowing than it advertised. Current liquidity appears able to carry that load, and lower bank lending rates plus stronger private credit show that policy easing is reaching borrowers. The risk is repetition: if large government issues continue, the same cash cannot indefinitely finance public debt and expand private lending without pressure. The next evidence will come from the 17 August settlement, the following bill auction and whether KESONIA remains anchored near 8.75%. [1] [3] [4] [5]
