The Central Bank of Nigeria (CBN) has cut the interest rate on one-year Treasury Bills below 17 per cent, marking the second consecutive reduction in the rate as investor demand for government securities remains strong.
At the Treasury Bills primary market auction held on Wednesday, September 2, 2026, investors submitted a combined ₦3.35 trillion in bids for Treasury Bills across three different maturities.
The CBN had initially offered Treasury Bills worth ₦700 billion but eventually allotted ₦865.71 billion to investors. The amount allotted was therefore about ₦165.71 billion higher than the original offer.
The biggest change came from the 364-day Treasury Bill, which is considered the benchmark one-year instrument.
The CBN reduced the stop rate on the 364-day bill to 16.84 per cent, down from 17.15 per cent at the previous auction held on August 26.
The latest reduction represents a 31-basis-point decline and takes the one-year Treasury Bills rate to its lowest level since the June 3 auction, when it stood at 16.35 per cent.
It is also the second consecutive auction at which the CBN has reduced the rate.
At the August 26 auction, the one-year stop rate had already been reduced from 17.59 per cent to 17.15 per cent. With the latest cut to 16.84 per cent, the rate has now fallen by a total of 75 basis points across two consecutive auctions.
Despite the reduction in the rate, investor demand for the longer-term Treasury Bill remained extremely strong.
The 364-day bill attracted ₦3.238 trillion in subscriptions against an offer of ₦500 billion. This means investors submitted bids worth more than six times the amount originally offered.
The CBN eventually allotted ₦762.17 billion of the one-year Treasury Bill at the 16.84 per cent stop rate.
The strong demand for the 364-day instrument shows that investors are still interested in locking their money into government securities for a longer period, even though the return offered by the CBN is gradually declining.
By comparison, demand for the shorter-term instruments was considerably weaker.
For the 91-day Treasury Bill, the CBN offered ₦100 billion while investors submitted ₦76.82 billion in bids. The apex bank allotted ₦76.28 billion at a stop rate of 16.30 per cent.
The 182-day Treasury Bill attracted only ₦33.51 billion in subscriptions against an offer of ₦100 billion. The CBN allotted ₦27.27 billion at a stop rate of 16.50 per cent.
The figures show a clear difference in investor preference. While the shorter instruments struggled to attract enough subscriptions, the one-year bill received overwhelming demand.
According to data from the latest auction, the 364-day bill accounted for approximately 96.7 per cent of total subscriptions across the three maturities.
The development is significant for Nigeria’s financial market because Treasury Bills are widely used by banks, pension funds, asset managers, companies and other investors to manage their funds and earn returns on relatively low-risk government securities.
Treasury Bills are short-term government debt instruments issued to raise money for the government and manage liquidity in the financial system. The Debt Management Office provides information on Nigeria’s Treasury Bills and other government securities.
The latest auction could also have implications for investors who have become accustomed to high fixed-income returns.
For several months, investors have enjoyed relatively high yields on Nigerian government securities. The recent reduction suggests that the environment may be gradually changing.
If Treasury Bills yields continue to decline, investors may begin looking for other assets that can provide competitive returns.
Some investors could consider equities, corporate bonds, money-market instruments and other investment opportunities as they compare the returns available across the market.
However, Treasury Bills are likely to remain attractive to many investors because of their relatively low credit risk and the opportunity to lock in returns for a specified period.
The latest auction also provides an indication of the level of liquidity available in Nigeria’s financial system.
The fact that investors submitted ₦3.35 trillion in bids against an offer of only ₦700 billion demonstrates the strong appetite for government securities.
The CBN therefore had room to reduce the rate while still attracting significant demand.
The latest reduction could also increase expectations about the direction of monetary policy in Nigeria.
Market participants are watching the CBN closely ahead of its next Monetary Policy Committee meeting. Continued moderation in Treasury Bills yields could strengthen expectations that interest rates may eventually begin to move lower if inflation and other economic conditions allow.
However, the Treasury Bills auction alone does not mean that the CBN has officially announced a change in its broader monetary policy stance.
For businesses and consumers, changes in interest rates are important because they can influence the cost of borrowing.
If interest rates decline more broadly, banks could eventually face lower funding costs, although the effect on lending rates depends on several factors, including inflation, credit risk, liquidity and competition among financial institutions.
For the Federal Government, lower Treasury Bills yields could also help reduce the cost of short-term borrowing.
The government regularly uses domestic securities to raise funds, and the interest rate attached to those securities determines how much it will eventually pay investors.
A sustained decline in yields could therefore provide some relief to government finances, although the overall impact depends on the amount borrowed and the maturity of the securities.
The latest auction also highlights the growing preference among investors for longer-dated Treasury Bills.
The 364-day bill’s overwhelming subscription figure suggests that investors may be trying to lock in current returns for a full year before rates potentially move lower.
This could explain why demand for the one-year instrument was significantly stronger than demand for the 91-day and 182-day bills.
For now, the CBN appears to be taking advantage of the strong demand for government securities to gradually lower the cost of borrowing while continuing to attract substantial investor participation.
The latest 16.84 per cent stop rate is therefore an important development for Nigeria’s banking and investment sectors.
Investors will now be watching upcoming Treasury Bills auctions to see whether the downward trend continues.
If the CBN cuts the rate further in future auctions, it could signal a broader shift towards lower fixed-income yields in Nigeria.
On the other hand, any renewed inflationary pressure or changes in liquidity conditions could affect the direction of rates.
For the moment, however, the latest auction shows that investor appetite for Nigerian government securities remains strong even as yields decline.
