The Central Bank of Nigeria (CBN) returned approximately ₦2.87 trillion to the banking system in October 2026 as repayments on maturing financial securities exceeded the value of newly issued instruments.
The development increased the amount of money available to commercial banks, although borrowing costs across the financial system remained relatively high.
According to a report by Nairametrics, the CBN sold ₦6.182 trillion worth of new Open Market Operations (OMO) bills in October, while previously issued bills worth ₦9.051 trillion reached maturity.
The difference of approximately ₦2.87 trillion represents the net amount returned to banks through the OMO transactions.
The development marked a significant shift from September, when the apex bank withdrew about ₦6.62 trillion from the financial system by selling ₦17.51 trillion in OMO bills against maturities of ₦10.89 trillion.
BANKING SYSTEM LIQUIDITY INCREASES
The increase in available funds was reflected in the banking system’s liquidity position, which rose by 56.75 per cent to ₦7.373 trillion in October, compared with ₦4.703 trillion recorded in September.
Data from the Financial Markets Dealers Association showed that banks had considerably more funds available during the period.
However, the increase in liquidity did not translate into a significant reduction in short-term borrowing costs.
The Nigeria Overnight Financing Rate remained at 20 per cent, while the overnight lending rate declined only slightly to 20.38 per cent.
The CBN’s benchmark Monetary Policy Rate also remained at 23 per cent following the reduction announced in September.
TREASURY BILL RETURNS DECLINE
Meanwhile, returns on Nigerian Treasury Bills continued to fall as investors competed for the limited securities available in the market.
The average Treasury Bill yield declined to 17.88 per cent, with returns on 91-day, 182-day and 364-day instruments falling to between 15.40 and 15.80 per cent.
The decline was partly attributed to strong investor demand and limited supply of government securities.
At its most recent auction, the Debt Management Office offered ₦800 billion worth of Treasury Bills but received subscriptions of approximately ₦1.91 trillion.
Despite the strong demand, only ₦71.16 billion worth of bills was allotted, representing about nine per cent of the amount initially offered.
When investors compete for fewer available securities, their prices tend to rise while the returns offered to new buyers decline.
However, lower Treasury Bill yields do not necessarily mean commercial banks are reducing interest rates on loans to individuals and businesses.
NOVEMBER LIQUIDITY INFLOWS COULD TEST CBN POLICY
Attention is now shifting to November, when the Financial Markets Dealers Association expects approximately ₦13.79 trillion to enter the financial system through maturing securities and government payments.
The projected inflow could further increase the amount of money available to banks, depending on how the CBN manages its monetary operations.
The apex bank could conduct additional OMO sales to absorb some of the excess liquidity or allow more funds to remain within the banking system.
The direction of its next move will be important in determining whether the current easing in liquidity conditions continues.
WHAT IT MEANS FOR BUSINESSES AND HOUSEHOLDS
Despite the additional funds available to banks, Nigerian households and businesses should not expect an immediate reduction in borrowing costs.
Commercial banks still determine their lending rates based on several factors, including monetary policy conditions, credit risks and their own funding requirements.
Consequently, increased liquidity does not automatically translate into cheaper business loans, overdrafts or personal credit facilities.
Small businesses seeking financing may therefore continue to face expensive borrowing conditions even as banks hold more available funds.
The situation also highlights the difference between improvements in financial market liquidity and the economic conditions experienced by ordinary Nigerians.
THREE KEY DEVELOPMENTS TO WATCH
Market observers will be paying attention to three major indicators in November:
- CBN’s OMO operations: Whether the apex bank increases the sale of new securities to withdraw some of the projected ₦13.79 trillion inflow.
- Interbank lending rates: Whether overnight borrowing costs begin to decline as more money becomes available within the banking system.
- Treasury Bill auctions: Whether the government increases the supply of short-term securities to meet investor demand.
The October figures indicate that more money has returned to the banking system, but the impact on the wider economy remains uncertain.
For now, the reduction in Treasury Bill yields and increase in banking liquidity have not produced a corresponding fall in borrowing costs.
How the CBN manages the expected November inflows could determine whether the additional liquidity eventually supports cheaper financing for Nigerian businesses and households.
