- •The 182-day was the weakest, drawing KSh 1.9 billion against KSh 10 billion on offer (19.4% performance) and the 91-day fared a little better at 40.5%.
- •In contrast, the 364-day remained in strong demand, attracting KSh 11.5 billion against KSh 10 billion on offer (115.3%).
Auction Outcome
Drivers of the Rate Decline
Several factors explain the sustained fall in T-bill yields over the past 12 months:
- •Monetary easing: The Central Bank has lowered its policy rate by a cumulative 275 bps in 2025, now at 9.50%, anchoring lower returns at the short end.
- •Contained inflation: Annual inflation has remained within target, ranging between 3.3% and 4.5% this year, reinforcing lower nominal rates.
- •Easier liquidity: Interbank rates have stayed in the mid-9s, providing funding comfort to banks and investors.
- •Issuance strategy: Treasury has aimed to lengthen maturities and reduce reliance on short-dated bills, easing pressure on shorter tenors.
- •Reduced risk premium: Successful external financing and debt management steps have calmed investor concerns, compressing yields.
Demand Split by Tenor
Investor behavior has clearly shifted. Banks and funds are locking in nearly 10% returns on the 364-day to avoid reinvestment risk in a falling rate environment, driving oversubscription for over a month.
By contrast, the 91-day and 182-day, closely tied to the softening policy outlook, have consistently seen heavy undersubscription.
The September 29 auction reinforces the trend: investors prefer duration at current yields, even as short-tenor rates mark multi-year lows.
