Introduction

The Central Bank of Nigeria has announced a fresh N2.5 trillion Open Market Operations auction, coinciding with the maturity of a near-identical N2.43 trillion liquidity repayment on the same day, September 29, 2026. This near one-for-one match underscores the CBN's continued focus on managing systemic liquidity within Nigeria's banking system.

What Happened

According to the CBN's auction notice, the offering spans three tenors: N500 billion in 147-day instruments maturing February 23, 2027; N1 trillion in 182-day paper maturing March 30, 2027; and N1 trillion in 266-day instruments maturing June 22, 2027. Bidding was expected to close at 10:30 a.m. The new offer is closely aligned with the N2.433 trillion OMO repayment due on the same date, differing by only N66.765 billion.

Why This Matters

With banks already holding more than N6.2 trillion at the Standing Deposit Facility, the CBN's latest operation serves as another major liquidity sterilisation move. The auction's structure—80 percent in longer-tenor 182-day and 266-day instruments, and 20 percent in 147-day paper—signals the apex bank's intent to extend liquidity absorption deeper into 2027. Investor demand remained robust, consistent with broader trends of strong subscription rates across September's OMO series.

Key Takeaways

  • The N2.5 trillion offer is approximately 102.7 percent of the N2.433 trillion repayment, reflecting a near-perfect match.
  • Longer-maturity instruments dominate the auction, with the 182-day and 266-day papers together accounting for N2 trillion, or 80 percent of the total offer.
  • Bank placements at the Standing Deposit Facility rose to approximately N6.278 trillion by September 29, up from N6.014 trillion the previous day and N5.899 trillion on September 25.
  • September 2026 OMO auctions recorded cumulative investor bids exceeding N20.58 trillion, more than five times the total amount initially offered across four weekly draws.
  • The CBN's Monetary Policy Committee recently reduced the Monetary Policy Rate by 350 basis points to 23 percent, aiming to align the benchmark with prevailing money-market conditions.

Conclusion

The September 29, 2026 OMO auction illustrates the CBN's strategy of matching liquidity injections with synchronized maturities to maintain control over system-wide cash flow. As surplus liquidity persists above N6.2 trillion, the success of this auction—and the stop rate accepted by investors—will shape the trajectory of short-term interest rates through the remainder of 2026 and into early 2027.
