Nigeria’s short-term money market recorded renewed pressure on liquidity after recent Central Bank of Nigeria (CBN) operations reduced available cash in the banking system, pushing the overnight lending rate higher.
The overnight rate, which measures the cost banks pay to borrow funds from one another for very short periods, rose to 22.20 per cent, reflecting tighter conditions in the financial market following government securities transactions and the CBN’s liquidity management activities.
The movement highlights the continued balancing act facing the apex bank as it attempts to control excess liquidity, manage inflationary pressures and maintain stability in the financial system.
According to market data from Herwood Securities Limited, system liquidity opened at a N3.66tn credit balance, representing a decline of about N930bn from the previous session’s N4.61tn position.
The reduction followed the settlement of treasury bills purchased by banks and institutional investors, which temporarily removed funds from circulation within the banking system.
A major factor behind recent liquidity tightening was the Central Bank of Nigeria’s Open Market Operations (OMO), through which it sells securities to absorb excess funds from financial institutions.
The apex bank sold N2.888tn worth of OMO bills during the week as part of efforts to reduce surplus cash in the system.
When banks purchase these instruments, money that could have remained available for lending or interbank transactions is temporarily absorbed, often leading to higher short-term borrowing costs.
The overnight rate increase therefore reflected the immediate impact of reduced liquidity rather than a shortage of funds within the banking sector.
Despite the decline, market data showed that the banking system remained in a liquidity surplus position, indicating that financial institutions still had significant cash available.
The liquidity position earlier in the week had supported strong demand for treasury bills as banks and other investors sought short-term investment opportunities.
Treasury bills are government-issued short-term securities used by the CBN and the Federal Government for liquidity management and domestic financing.
Higher demand for these instruments can occur when banks have excess cash and seek relatively low-risk assets.
However, when large volumes of funds are absorbed through securities sales, the immediate effect can be tighter conditions in the interbank market.
Market participants expect liquidity conditions to improve as treasury bills worth N734.81bn mature and funds return to the banking system.
The maturity of these securities could provide additional cash for banks and reduce pressure on short-term funding costs if no major liquidity withdrawals occur.
Analysts expect the overnight rate and open buyback rate to remain relatively stable around current levels in the near term, depending on future actions by the CBN.
The open buyback rate remained unchanged at 22 per cent during the period under review.
The overnight lending rate is an important indicator of conditions in Nigeria’s money market because it reflects the cost of short-term funding between banks.
A rise in the rate signals tighter liquidity, while a decline often indicates easier access to funds within the banking system.
However, changes in overnight rates do not immediately translate into equivalent movements in consumer lending rates.
Commercial banks consider several factors when setting loan prices, including the CBN’s benchmark interest rate, inflation expectations, credit risks, operating costs and market conditions.
The recent movement therefore provides more insight into banking system liquidity than direct information about household borrowing costs.
The latest liquidity adjustment comes as the Central Bank continues efforts to manage money supply conditions in the economy.
Liquidity management remains one of the tools available to central banks globally for influencing financial conditions.
By withdrawing excess funds through instruments such as OMO bills and treasury operations, the CBN seeks to prevent excessive liquidity from worsening inflationary pressures.
At the same time, policymakers must ensure that liquidity conditions do not become so restrictive that they weaken financial market stability or limit economic activity.
The movement in Nigeria’s overnight rate shows the strong influence of central bank operations on short-term market conditions.
As more treasury bills mature and funds return to the banking system, attention will remain on whether liquidity improves or whether further policy actions lead to additional adjustments in money market rates.
