CBN Absorbs N2.72 Trillion as OMO Bids Hit N5.74 Trillion

Nigeria's central bank absorbed N2.72 trillion of surplus cash at Friday's open market operation, the largest single-day allotment of the month to date, after investors submitted N5.74 trillion in bids for a N1.5 trillion offer — nearly four times the amount the Apex institution planned to take out of the system. The auction, covering 179-day, 270-day and 361-day bills, closed the first full week of November with the Central Bank of Nigeria still hunting liquidity a market keeps pouring back into its lap.

The oversubscription was not a surprise so much as a confirmation. At the Nov 3 OMO, the apex bank had already replaced N2.95 trillion, and a treasury-bill sale the following day absorbed another N509.41 billion. Stop rates at Friday's operation cleared lower than the previous week — 17.25 per cent on the 179-day paper, 16.54 per cent on the 270-day and 15.74 per cent on the 361-day — down from the 17.67–17.77 per cent range that cleared on Nov 3, evidence that it will drive investors to park cash at the shortest end of the curve if the price must come from somewhere.

A liquidity cycle the CBN cannot yet break

Government Securities Dealers Association data shows the shape of the problem. In the week ended Nov 6, OMO primary-market debits of N5.72 trillion outran N2.02 trillion of maturities, yet average system liquidity still settled at a net long position of N7.20 trillion — a moderation, but only from an even larger N8.05 trillion the week before. The banking system is so flush that even consecutive multi-trillion naira withdrawals leave it swimming in cash.

The money-market rate structure tells the same story. The overnight rate eased 18 basis points week-on-week to 20.2 per cent and the open buy-back rate held at 20 per cent, both anchored by the CBN's 20 per cent, standing rate rather than by any sustained cash squeeze. In a system where naira money costs the banks roughly what it sold for Friday, the OMO is functioning less as a liquidity mop and more as a yield anchor — pulling idle balances into the CBN's own paper and defining how long a few basis points of carry is worth holding.

Secondary-market pricing has been dragged along. The cost of treasury bills tracked on the secondary market fell to an average 18.2 per cent for the week, a roughly two-basis-point contraction, while OMO bill returns compressed another six points to 18.6 per cent. Yields on FGN bonds average 16.34 per cent, one basis point lower with the short end and three points tighter. Yields falling while the central bank is withdrawing trillions is the paradox signature of a market that believes the mop-up tempo must ultimately ease — or that unmet OMO demand is being recycled into whatever paper is available.

What the demand is really saying

Three forces are behind the N5.74 trillion bid wall. First, the cheap money cycle: after the strong disinflation that peaked at 15.39 per cent in October and the CBN's 23 per cent policy-rate cut earlier in the cycle, banks and cash-rich pension and insurance portfolios have been paid to hold a big part of their portfolios in naira instruments, and OMO bills remain the cleanest short-dated Nigerian gross-liquidity exposure. Second, the fiscal calendar is quiet: with no major bond auction issuing fresh government paper in this window, the OMO has become the default parking lot. Third, FMICO-backed pension and insurance reform keeps pulling long-duration liabilities toward the front end, adding structural bid to every auction.

For those corporate treasurers the arithmetic is flattering. A tripartite of 179-day, 270-day and 361-day bills clearing between 15.74 and 17.25 per cent — more than 400 basis points above the average inflation print — is the rare Nigerian investment-grade carry that survives both a currency headache and a slowing disinflation turnaround. The risk is duration: if the CBN keeps allotting at lower clears, re-investment risk compounds with every cycle, exactly the trap that caught importers and money-market funds in earlier cutting cycles.

Next week's N2.3 trillion test

The week ahead supplies the ramp for this auction cycle to unwind: OMO maturities of roughly N2.3 trillion will inject fresh cash, and the central bank will decide whether to absorb it, roll it, or let the system run long again. Each choice carries consequences. A full re-absorption at lower yield clears would push money-market rates toward a new, tighter equilibrium and pressure bank net interest margins that have been rebuilding all year. A softer mop-up would let overnight rates fall and give equities and private credit a liquidity runway the equity market has been waiting for.

The debt side is already adapting. The Debt Management Office has raised about N1.82 trillion across four fourth-quarter treasury-bill auctions against N2.95 trillion offered, holding clears at 15.40, 15.79 and 15.80 per cent through Nov 4 — meaning government short-end funding remains available at yields well below the OMO clears, an unusual reverse hierarchy of rates that bootstrap short-term Nigerian debt markets. The cost of that hierarchy is a central bank paying up to defend itself, while the treasury funds at a discount.

For a monetary authority that has spent much of 2026 leaning against surging liquidity, Friday's auction crystallises the dilemma. It can keep clearing at lower rates to defend its inflation-fighting credibility, or it can let the market clear itself into a cheaper, faster financial system. The N5.74 trillion of bids says which side investors are sitting on — before the central bank answers, they will price their conviction in both directions and wait.
