The Central Bank of Nigeria (CBN) raised the stop rate on its benchmark 364-day Treasury Bill to 17.59% at Wednesday’s auction, defying expectations that strong investor demand would push borrowing costs lower.
Investors submitted a combined N4.4 trillion in bids across the three-tenor Treasury Bill offer against N700 billion advertised by the apex bank, according to auction results obtained by Nairametrics at the close of business on Wednesday, August 12, 2026.
The increase marks a reversal from the previous auction on July 29, when the CBN reduced the one-year Treasury Bill stop rate by 31 basis points despite subscriptions reaching almost seven times the amount offered.
What you should know
The latest auction highlights the CBN’s willingness to maintain relatively high short-term government borrowing costs despite exceptionally strong demand for Treasury Bills.
The 364-day Treasury Bill attracted the overwhelming majority of investor interest, with subscriptions reaching N4.19 trillion against an offer size of N500 billion.
This means investors submitted bids worth more than eight times the amount the CBN offered for the one-year instrument.
Despite the strong demand, the apex bank increased the clearing rate rather than lowering or maintaining it.
The move could have implications for yields across Nigeria’s fixed-income market, particularly as investors continue to assess the direction of monetary policy and inflation.
What the data is saying
N4.4 trillion bids for N700 billion offer
Investors submitted approximately N4.4 trillion in bids across the three Treasury Bill maturities offered at the auction.
Against the combined offer size of N700 billion, the auction was heavily oversubscribed, highlighting strong appetite for government securities.
364-day bill attracts N4.19 trillion
The one-year Treasury Bill was by far the most sought-after instrument.
Investors submitted N4.19 trillion in bids for the 364-day bill, compared with the N500 billion offered by the CBN.
The level of demand represents more than eight times the amount available at the auction.
Stop rate rises to 17.59%
Despite the overwhelming demand, the CBN raised the 364-day stop rate to 17.59%.
This represents a sharp reversal from the July 29 auction, when the apex bank cut the one-year stop rate by 31 basis points.
The latest decision suggests that strong demand alone was not sufficient to push the clearing yield lower, with the CBN instead accepting a higher borrowing cost at Wednesday’s auction.
What this means for investors
The higher stop rate could make Treasury Bills more attractive to investors seeking relatively high-yield, short-term instruments, particularly institutional investors managing large pools of liquidity.
At the same time, the decision provides another signal that borrowing costs may remain elevated even as the CBN continues to monitor inflation, liquidity conditions and broader financial-market stability.
The combination of record-level demand and a higher clearing rate therefore makes Wednesday’s auction an important indicator of the current balance between investor appetite for Nigerian government securities and the CBN’s approach to domestic borrowing costs.
