The liquidity in Nigeria's banking system has surged to N8.84 trillion, marking a 37.01% increase from N6.45 trillion earlier this year. This rise comes ahead of the Central Bank of Nigeria's (CBN) latest Open Market Operation (OMO) bills settlement, prompting expectations of a substantial cash withdrawal from the financial system.

Market data from AIICO Capital Limited indicates that the current liquidity level is more than double the N3.82 trillion recorded at the start of the year. This increase is attributed to a combination of OMO maturities and other inflows into the money market, despite the CBN's ongoing efforts to absorb excess liquidity through the sale of government securities.

On Tuesday, the CBN offered N2.5 trillion in OMO bills across three maturities, with investor demand pushing the total amount raised to approximately N5 trillion. This transaction is expected to help reverse part of the liquidity buildup once the securities are settled, with market participants keenly observing its impact on short-term funding rates.

Despite the abundant liquidity, there has been a modest increase in overnight borrowing costs. The overnight lending rate rose by 28 basis points to 20.86%, while the overnight policy rate remained stable at 20.50%. The Nigerian Overnight Financing Rate also held steady at 20%, which is the lower boundary of the current interest-rate corridor following the CBN's recent monetary policy easing. The average Treasury bill rate has not changed, remaining at 17.84%.

AIICO Capital analysts predict that money market rates will likely stay close to the 20% floor as long as the banking system's liquidity remains above N8 trillion. However, they anticipate that the settlement of the latest OMO transaction will significantly reduce the cash available to banks. Approximately N4.69 trillion is expected to be debited from the system upon the settlement of the OMO sale, representing a considerable withdrawal from the current liquidity pool and potentially altering the direction of short-term money-market rates.

The current liquidity position is a crucial indicator for banks as they navigate their cash management strategies amid the CBN's continued use of open-market operations to regulate liquidity in the financial system. The high demand for OMO instruments also underscores a persistent appetite for high-yielding naira assets, particularly as monetary policy and short-term interest rates continue to adjust.
