CBN Reprices OMO, Treasury Bills Lower as N7.35tn Liquidity Floods Banking System

Banking system liquidity surged to N7.35 trillion as the Central Bank of Nigeria (CBN) lowered rates on Open Market Operation (OMO) bills and Nigerian Treasury Bills, supported by strong investor demand for short-term government securities.

Liquidity in the banking system increased by N3.02 trillion from N4.33 trillion recorded in the previous session, leaving financial institutions with substantial funds to deploy across the money market.

The increase coincided with heavy demand at the CBN’s latest OMO auction, where investors submitted N6.32 trillion in bids for N1 trillion initially offered by the apex bank.

Faced with demand more than six times the amount on offer, the CBN eventually allotted about N4.4 trillion while clearing the securities at lower yields.

The result showed that investors remain willing to commit substantial funds to naira-denominated fixed-income securities even as the returns available on those instruments continue to decline.

At the auction, the shortest OMO instrument, maturing on December 1, 2026, cleared at 19.14 percent, down from 19.59 percent at the previous auction.

The February 2027 instrument cleared at 18.49 percent, compared with 18.99 percent previously, while another February 2027 maturity was priced at 18.41 percent.

The clearing rates placed all three instruments below 20 percent and reinforced the downward repricing taking place at the short end of Nigeria’s fixed-income market.

Strong Demand Gives CBN Room to Lower Rates

The volume of bids received at the auction strengthened the CBN’s ability to absorb excess funds at lower rates.

With investors seeking more than N6 trillion worth of securities against an initial N1 trillion offer, the apex bank had considerable flexibility over the amount accepted and the yields at which bids were allotted.

The CBN eventually withdrew approximately N4.4 trillion through the operation.

The auction came as large OMO maturities returned funds to the financial system, with nearly N3 trillion expected to mature during the week.

Despite the amount absorbed by the central bank, interbank funding conditions remained relatively stable. The Open Repo Rate stood around 22 percent, while the overnight rate was approximately 22.15 percent.

Treasury Bill Rates Also Decline

The repricing has extended beyond OMO bills to Nigerian Treasury Bills, where yields have also been moving lower.

The one-year Treasury Bill rate has declined progressively across recent auctions as demand for government securities remains strong.

The movement suggests that the Federal Government is increasingly able to raise short-term domestic funding at lower rates than it paid earlier in the year.

That could become important for Nigeria’s debt-servicing costs if the decline persists.

Treasury Bills are regularly issued to meet short-term government financing requirements. Lower yields reduce the interest payable when new securities are issued or maturing obligations are refinanced.

For investors, the same development means declining returns.

Banks, pension funds, asset managers and other institutional investors that benefited from the high-yield environment will increasingly have to determine whether government securities remain sufficiently attractive relative to other investment opportunities.

Falling Yields Could Reduce Government Borrowing Costs

For the Federal Government, sustained declines in Treasury Bill yields would provide some relief from the high cost of domestic borrowing.

Nigeria has relied heavily on the domestic debt market to finance government expenditure, with elevated interest rates increasing the cost of servicing those obligations.

The impact would be gradual because existing securities retain their contracted rates. However, refinancing maturing debt at progressively lower yields would reduce the marginal cost of government borrowing.

Continued strong demand at auctions would strengthen that advantage by allowing the government to reject expensive bids without necessarily compromising its funding objectives.

Investors May Look Beyond Fixed Income

Falling yields could also influence investment flows across Nigeria’s financial markets.

High returns on Treasury Bills, OMO securities and government bonds have given institutional investors attractive alternatives to riskier assets.

As those returns decline, portfolio managers may begin reassessing allocations to equities, corporate debt and other investments, particularly if inflation moderates and expectations of further monetary easing strengthen.

The Nigerian Exchange could benefit from some portfolio rotation, although lower fixed-income yields alone would not guarantee sustained inflows into equities.

Corporate borrowers could also benefit if the decline spreads further along the yield curve.

Government securities serve as an important benchmark for pricing private-sector debt. Lower benchmark yields can therefore improve financing conditions for companies seeking funds through commercial papers and corporate bonds.

Monetary Policy Remains Key

The sustainability of the decline will ultimately depend on monetary policy, inflation and conditions in the foreign exchange market.

The CBN must manage surplus funds without creating additional inflationary or exchange-rate pressure while avoiding financial conditions that unnecessarily constrain credit and economic activity.

OMO auctions provide the central bank with a mechanism for withdrawing excess money without relying solely on changes to the Monetary Policy Rate.

For investors, recent auctions increasingly point to a lower-yield environment for short-term naira assets.

With demand remaining substantially above the volume of securities available, the CBN and Federal Government have greater scope to secure funds at lower rates, potentially reshaping borrowing costs and investment decisions across Nigeria’s financial markets.
