The CBN withdraws liquidity via OMO operations as the apex bank absorbed N3.31 trillion from the financial sector during its latest debt sale.
According to transaction figures released from the October 6 auction, the Central Bank of Nigeria conducted the open market operation to sterilize surplus cash. Although approximately N2.17 trillion in maturing bills flowed back into commercial banking reserves, the aggressive mop-up resulted in a net cash extraction of about N1.14 trillion.
Backstory: Managing Surplus Bank Reserves and Inflationary Pressures
To understand why monetary authorities continue these large-scale debt auctions, we must examine how liquidity surges impact broader financial stability. For months, massive inflows from maturing government securities created excess cash reserves across commercial banks. When unmanaged, surplus liquidity can fuel currency speculation and accelerate domestic inflation.

To maintain price stability and enforce monetary discipline, the central bank under Governor Olayemi Cardoso repeatedly deployed Open Market Operations (OMO) as a key intervention tool. Throughout September alone, the regulator allotted over N17.5 trillion in fresh securities to neutralize cash buildup across the interbank market.
- September 2026 Mop-Up: Apex bank allotted N17.51 trillion in OMO bills against N10.89 trillion in maturities, achieving a net withdrawal of N6.62 trillion.
- October 6 Auction Offer: Central bank offered N2 trillion across 147-day and 182-day tenors to target excess liquidity exceeding N5 trillion.
- Investor Response: Heavy market demand drove total subscriptions to N3.51 trillion, allowing the regulator to allot N3.31 trillion.
Strong Demand Drives Oversubscription and Tightens Money Market Rates
During the auction, investor appetite remained robust, with the longest-dated 182-day instrument attracting N2.7 trillion in total allocations. Meanwhile, stop rates settled at 17.22% for the 147-day bill and 16.92% for the 182-day paper.
Despite the substantial cash withdrawal, commercial banks maintained significant reserves at the Standing Deposit Facility window. However, the net liquidity mop-up pushed overnight interbank borrowing rates upward by 25 basis points to 22.2%.
“The latest operation highlights the central bank’s continued reliance on OMO sales to sterilize surplus cash and prevent money market funds from putting pressure on price stability,” noted market analysts reviewing the auction results.
In conclusion, as the CBN withdraws liquidity via OMO sales, financial regulators continue balancing interbank cash levels against inflationary risks. Persistent liquidity management will remain vital to preserving monetary equilibrium across the domestic economy.
