The Central Bank of Nigeria (CBN) raised N1.92 trillion at its Open Market Operations (OMO) auction on Tuesday, April 21, 2026, with stop rates climbing as high as 21.90%, signaling sustained monetary tightening and strong investor appetite for high-yield instruments.
This is according to auction results published by the apex bank on Wednesday.
The development highlights the CBN’s continued efforts to manage liquidity levels in the financial system while responding to elevated inflationary pressures and strong demand for government securities.
What the data is saying:
The OMO auction results indicate aggressive liquidity tightening by the apex bank, supported by strong investor demand and elevated yields across tenors. Total subscriptions across the three tenors reached N2.22 trillion, significantly exceeding the N600 billion initially offered.
- The 140-day tenor attracted the highest demand with subscriptions of N1.25 trillion, reflecting investor preference for longer-duration instruments at high yields.
- The 7-day bill recorded the second-highest demand at N884 billion, while the 91-day instrument lagged with N87 billion in subscriptions.
- In terms of allotments, the CBN sold N1.21 trillion in 140-day bills, N684 billion in 7-day bills, and N21 billion in 91-day bills, bringing total sales to N1.92 trillion.
- Stop rates cleared at 21.90% for the 7-day tenor, 19.87% for the 91-day, and 19.91% for the 140-day bills, reflecting persistently high yield levels across the curve.
The data underscores strong investor appetite for short-term securities amid expectations of continued tight liquidity conditions and elevated interest rates.
More insights:
The scale of the allotment—more than triple the initial offer—suggests a deliberate move by the CBN to absorb excess liquidity from the financial system. This comes as the apex bank simultaneously repaid N2.16 trillion in Primary Market maturities on the same day.
- The CBN had earlier repaid N92.8 billion in Treasury Bills and FGN Bond maturities across three sessions between April 15 and April 17.
- With total Primary Market repayments estimated at N2.25 trillion and net OMO sales at N1.92 trillion, only about N330 billion was left circulating in the system.
- The heavy issuance of OMO bills is aimed at further tightening liquidity conditions and sustaining upward pressure on short-term interest rates.
- Strong demand for longer tenors, particularly the 140-day bill, reflects investor positioning for sustained high yields in the near term.
This aggressive liquidity mop-up signals the CBN’s intent to maintain tight monetary conditions, potentially impacting borrowing costs and overall market liquidity.
What you should know:
The stop rate of 21.90% on the 7-day bill represents the highest among the offered tenors, but it does not mean the CBN will pay that rate on the full N684 billion allotted. Interest payments are calculated using a prorated method based on a 364-day year.
- Money market traders explain that the interest is derived by multiplying the principal by the stop rate, dividing by 364 days, and then multiplying by the tenor duration.
- Using this method, the CBN is expected to pay approximately N2.88 billion as interest for the 7-day bill.
- The same calculation approach applies to the 91-day and 140-day instruments, ensuring proportional interest payments based on duration.
- The intensified use of OMO bills remains a key strategy for controlling excess liquidity and curbing inflationary pressures in the economy.
While high issuance supports liquidity management, it also raises borrowing costs with potential implications for debt accumulation and broader economic activity.
