CBN eases OMO mop-up, releases N2.87tn into banking system

Open Market Operations are the CBN’s purchases and sales of short-term government securities. They help manage how much cash banks hold and how easily money moves through the financial system. This matters because liquidity can influence lending conditions and short-term market yields.

When the CBN sells fresh OMO bills, banks pay for them, so money leaves the banking system. When older bills mature and the CBN repays investors, money returns to banks. The balance between new sales and repayments determines whether the CBN is absorbing or releasing funds.

In October, the CBN issued N6.182tn in new OMO bills but repaid N9.051tn in maturities. That created a net repayment of about N2.87tn before other movements. In September, sales exceeded maturities, so the CBN withdrew N6.62tn. The CBN can adjust future auctions to manage excess funds.

The CBN effectively released about N2.87tn in October because its repayments on maturing OMO bills exceeded its sales of new bills. This is called a net liquidity release. It means more money returned to banks than was collected from them through fresh securities.

The calculation is straightforward. The CBN issued N6.182tn in new OMO bills and repaid N9.051tn in maturing bills. Subtracting new issuance from maturities gives N2.869tn, reported as about N2.87tn. This figure excludes other liquidity movements, such as government payments.

The release helped support a much larger cash balance in the banking system. Liquidity rose from N4.703tn in September to N7.373tn in October, a 56.75 per cent increase. The October result contrasted with September, when the CBN withdrew N6.62tn through OMO activity. Future auctions could absorb some of the released funds.

October marked a major reversal in the CBN’s liquidity approach. Instead of taking more money from banks, the central bank allowed repayments to exceed fresh OMO sales. The result was a net release of about N2.87tn before other liquidity movements.

September showed the opposite pattern. The CBN sold N17.51tn in OMO securities while only N10.89tn matured. Sales therefore exceeded repayments by N6.62tn, withdrawing that amount from the financial system. October sales were much lower, at N6.182tn, while maturities reached N9.051tn.

The change amounted to an approximately N9.49tn swing, from a N6.62tn withdrawal to a N2.87tn release. Banking-system liquidity consequently rose 56.75 per cent in October. The shift became especially clear at the final October auction, when the CBN reduced its allotments. It could still reverse course through future OMO sales.

Banking-system liquidity rose because more money stayed in banks during October. The CBN reduced its OMO absorption, allowing repayments on maturing securities to exceed fresh sales. That left banks with additional cash available for transactions and investment.

The figures show the change clearly. October brought N9.051tn in maturing OMO repayments against N6.182tn in new sales, creating a net repayment of about N2.87tn. The FMDA also pointed to government disbursements and repayments on maturing securities as contributors to stronger bank cash balances.

As a result, liquidity increased from N4.703tn in September to N7.373tn in October, a 56.75 per cent rise. The increase does not mean all the money will remain available indefinitely. The CBN may absorb part of it through new OMO sales, while banks must still maintain adequate liquidity buffers. November inflows could add further funds.

When banks hold more excess cash, they have more funds to place in short-term instruments. They may compete to buy Treasury bills and other securities rather than leave money idle. Stronger demand can push the yields investors receive downward.

The article links lower OMO mop-up with more funds available for T-bills and other short-term instruments. If the CBN continues the selective allotments seen at the end of October, excess liquidity could persist. That would exert downward pressure on short-term money-market yields.

The effect was not dramatic across every rate in October. The Nigeria Overnight Financing Rate stayed at 20 per cent, while the overnight rate slipped five basis points to 20.38 per cent. The Monetary Policy Rate also remained at 23 per cent. Future yields will depend on how much liquidity banks retain and how aggressively the CBN sells new OMO bills.

Projected inflows are not automatically permanent additions to banking-system liquidity. Money can enter through maturing securities and government payments, but the CBN can later remove some of it. This makes the final liquidity outcome depend on both incoming funds and central-bank action.

The FMDA projected N13.79tn in November inflows from maturing securities and government payments. If the CBN sells new OMO bills, banks and other investors will use some of those incoming funds to buy the securities. That process absorbs money from the banking system.

The article therefore cautions that November’s inflows may not all remain available to banks. The amount retained will depend largely on the volume of new securities offered and the CBN’s appetite for liquidity management. If allotments stay selective, excess liquidity could persist. If sales increase, the CBN could reduce the funds available for short-term investment.

Banks hold and deploy the funds circulating through Nigeria’s financial system. Government payments can send money into banks, while banks may invest available cash in T-bills and other short-term instruments. Their cash balances therefore change as payments, repayments, and investments move through the system.

Maturing securities return funds to investors, including banks. Fresh securities sales do the reverse by collecting money from buyers. The CBN manages this balance through OMO auctions. In October, it issued N6.182tn in new bills but repaid N9.051tn in maturities, producing a net repayment of about N2.87tn before other movements.

Government disbursements added to the increase, helping liquidity reach N7.373tn from N4.703tn. The CBN can still limit circulation by offering more new securities. November’s projected N13.79tn inflow may therefore be partly retained by banks or partly absorbed through further OMO sales.
