The Central Bank of Nigeria (CBN) is offering N2 trillion in Open Market Operations (OMO) bills on Thursday, October 22, 2026, as banking system liquidity remains elevated following substantial securities repayments.
According to the CBN’s auction notice, the offer comprises N1 trillion each of 138-day and 180-day bills, with bidding scheduled between 1:00 p.m. and 1:30 p.m today.
The auction comes after banks’ net placements at the CBN’s Standing Deposit Facility exceeded N6 trillion earlier in October, while the Financial Markets Dealers Association (FMDA) projected N2.067 trillion in OMO maturities for the week.
CBN splits N2 trillion OMO offer:
The CBN’s latest OMO auction offers two maturities, with equal amounts allocated to the 138-day and 180-day instruments. The shorter bill matures on March 9, 2027, while the longer bill matures on April 20, 2027.
The N2 trillion offer represents approximately 96.8% of the N2.067 trillion in OMO maturities projected by FMDA for the week beginning October 19.
- The 138-day OMO bill has an offer size of N1 trillion.
- The 180-day OMO bill also has an offer size of N1 trillion.
- Bidding is scheduled to run from 1:00 p.m. to 1:30 p.m. on Thursday.
- The difference between the offer and projected weekly OMO maturities is approximately N67 billion.
- The proximity of the two figures suggests that the auction could absorb part of the liquidity returning to the financial system through maturing securities.
- However, the notice does not establish that the CBN intends to replace those maturities on a one-for-one basis.
It also does not specify stop rates, subscriptions or allotments, which will only become known when the auction results are available.
Consequently, the amount of liquidity withdrawn will depend on the volume of bills eventually allotted rather than the announced offer alone.
OMO Repayments boost banking liquidity:
The auction follows a period of substantial liquidity releases from maturing OMO securities. Banks’ net placements at the CBN’s Standing Deposit Facility rose above N6 trillion after an OMO repayment of approximately N2.41 trillion on October 13.
According to Nairametrics’ analysis of CBN data, those placements remained above N6 trillion through October 16.
- FMDA reported that banking system liquidity increased by 69.39% to N6.283 trillion in the week ended October 16.
- The increase was from N3.709 trillion in the preceding week.
- OMO repayments contributed to the liquidity expansion, with no fresh OMO sales recorded during the review week.
- At the October 6 OMO auction, the CBN allotted approximately N3.31 trillion against an initial offer of N2 trillion and subscriptions of N3.51 trillion.
- The October 6 allotment exceeded the announced offer and was approximately N1.14 trillion higher than the N2.17 trillion in maturities recorded around that auction.
- The 182-day bill accounted for about 80.7% of the total allotment, indicating stronger demand for the longer instrument.
Stop rates settled at 17.22% for the 147-day bill and 16.92% for the 182-day bill, both below the rates recorded at the September 29 auction.
The CBN also sold approximately N17.51 trillion in OMO bills during September against N10.89 trillion in maturities, representing a net liquidity withdrawal of about N6.62 trillion.
OMO allotments determine liquidity impact:
The October 22 auction will provide another indication of how aggressively the CBN intends to absorb liquidity from the banking system. Although the offer is N2 trillion, recent auctions show that the final allotment can be substantially higher.
The results will also indicate whether investors continue to favour longer-dated OMO instruments and whether accepted yields maintain their recent downward trend.
- At the October 6 auction, the CBN allotted approximately 1.65 times its original N2 trillion offer.
- The latest 138-day and 180-day bills are close in tenor to the instruments offered on October 6.
- The previous stop rates of 17.22% and 16.92% provide a reference for assessing changes in accepted yields.
- September’s OMO subscriptions reached approximately N20.6 trillion, the highest reported for 2026.
- OMO bills are available to eligible market participants under CBN rules and are not offered directly to ordinary retail investors.
- The CBN’s notice does not provide a specific explanation for the latest auction beyond its role in routine liquidity management.
A larger allotment could absorb more liquidity than the projected weekly maturities, while a smaller allotment could leave more funds within the banking system. The final subscription figures, stop rates and allotment volumes will therefore determine whether the auction mainly offsets maturing securities or results in an additional net liquidity withdrawal.
