Introduction

Nigeria’s primary Treasury Bills market continues to reward the longest available tenor. At the most recent sale conducted by the Central Bank of Nigeria on behalf of the Debt Management Office, demand surged into the one-year instrument while shorter-dated bills attracted only modest interest. The November 11, 2026 auction reinforced a clear pattern: when yield differences across maturities are narrow, investors prefer to lock funds for a full year rather than commit to three- or six-month paper.

What Happened

The CBN offered N800 billion across three standard maturities, with N600 billion allocated to the 364-day bill. Investors submitted N1.079 trillion in bids for that one-year instrument alone, equal to 179.85% of its offer. In contrast, the 91-day bill drew just N19.18 billion against N100 billion on offer, while the 182-day note attracted N23.02 billion against the same amount. Together, the shorter tenors secured only N42.20 billion from a combined N200 billion offering.

Total subscriptions across all three bills reached approximately N1.12 trillion. The CBN ultimately allotted N713.31 billion, leaving N86.69 billion unallotted. Of the allotted amount, N672.91 billion went to the 364-day bill—exceeding its advertised offer—while the 91-day and 182-day instruments received N18.12 billion and N22.28 billion respectively. The one-year bill therefore represented about 96.2% of total subscriptions and roughly 94.3% of all allotments.

Why This Matters

The heavy concentration in the 364-day instrument matters for both the government and market participants. For the Debt Management Office, it offers a way to raise substantial funding without pushing borrowing costs sharply higher across the yield curve. For investors, the narrow spread between maturities means the one-year bill provides a modest but meaningful premium for locking funds longer, even though the incremental yield over shorter paper is small.

The auction also occurred against N148.565 billion in maturing Treasury Bills due for settlement on November 12, meaning the government offered significantly more new debt than was maturing. The market’s willingness to absorb such a large portion of the one-year offering signals sustained appetite for naira-denominated government securities, particularly at the longer end of the short-term curve.

Key Takeaways

  • Investors submitted N1.079 trillion for the 364-day Treasury Bill, covering 179.85% of the N600 billion offer.
  • The 91-day and 182-day bills together attracted only N42.20 billion against a combined N200 billion offer.
  • The CBN allotted N713.31 billion of the N800 billion offered, with the one-year bill receiving N672.91 billion.
  • Stop rates on November 11 were 15.40% for the 91-day bill, 15.79% for the 182-day bill, and 15.89% for the 364-day bill.
  • The 364-day rate increased by nine basis points from the previous auction, yet the gap between maturities remained narrow.
  • This continues a trend seen in recent auctions where the one-year instrument has dominated investor subscriptions.

Conclusion

The November 11 Treasury Bills auction reinforces a durable pattern in Nigeria’s fixed-income market: when yield differentials are slim, investors gravitate toward the longest available short-dated government security. Whether this preference persists at the next sale will depend on the CBN’s rate settings and the Debt Management Office’s issuance calendar. For now, the 364-day bill remains the clear favorite among participants in the primary Treasury Bills market.
