The Central Bank of Nigeria pumped a net N5.21 trillion into the banking system over the course of one week. This substantial liquidity release culminated in a single N2.48 trillion Open Market Operations repayment on August 11, 2026, which stood as the largest one-day injection of the period.
According to official financial data published by the apex bank, this liquidity surge occurred just ahead of the primary market auction on August 12, 2026. At this auction, the central bank aims to raise N700 billion in Treasury Bills on behalf of the Debt Management Office.
Massive OMO and Treasury Bill Repayments
The N5.21 trillion in total repayments reflects a combination of maturing OMO bills and Treasury Bills flowing back into the financial system. The N2.48 trillion repayment on August 11 made up the bulk of the late-week liquidity, representing 47.60% of the total injection.
Prior to this, the central bank executed N2.73 trillion in primary market repayments, which made up the remaining 52.40% of the weekly total. These repayments were split between N2.45 trillion on August 4 and N283.78 billion on August 6, 2026.
This liquidity influx exceeded early market expectations. Analysts at Cordros Securities had previously projected that about N1.58 trillion in OMO bills would mature during the week, a figure far surpassed by the actual N2.48 trillion single-day settlement on Tuesday.
Upcoming Treasury Bills Auction Dynamics
The scheduled August 12 auction follows the cancellation of a similarly sized N700 billion offer on August 5, 2026. That previous offer was called off after the central bank aggressively withdrew N4.69 trillion from the system through consecutive OMO auctions on August 3 and August 4.
With trillions of naira now back in the banking system, market analysts expect strong bidding and potential oversubscription at the upcoming Dutch auction. Recent issuance cycles have consistently shown high demand, particularly for longer-term instruments.
At the July 29 auction, the central bank allotted N1.25 trillion against a N700 billion offer, driven by demand for the 364-day bill. Earlier on July 8, the apex bank allotted N1.06 trillion, pushing the one-year stop rate to 17.70% from 17.34%, while the 182-day tranche saw weak demand, securing only N29.94 billion of the N100 billion offered.
The central bank has actively adjusted its liquidity management strategy. After absorbing N7.18 trillion through aggressive OMO sales in July, the bank has transitioned to alternating mop-up operations with large repayments to balance system liquidity.
