Introduction

The Debt Management Office latest Treasury Bills auction saw significant rejection of bids, with stop rates declining across the board as the office prioritized cost control over volume.

What Happened

At the October 28, 2026 auction, investors submitted nearly N1.91 trillion in bids against an N800 billion offer, resulting in a subscription coverage ratio of 2.38 times. The DMO allotted only N71.16 billion, representing less than 9% of total demand, while leaving approximately 96.27% of subscriptions unfilled. The 364-day instrument attracted N1.84 trillion in bids but received just N38.38 billion in allotments, a 2.09% acceptance rate. The 91-day bill saw N51.56 billion in subscriptions with N22.33 billion allotted at a stop rate of 15.40%. The 182-day bill recorded N20.27 billion in subscriptions, with N10.45 billion allotted at a stop rate of 15.79%.

  • The 364-day instrument attracted N1.84 trillion in bids but received only N38.38 billion in allotments, a 2.09% acceptance rate.
  • The 91-day bill saw N51.56 billion in subscriptions with N22.33 billion allotted at a stop rate of 15.40%.
  • The 182-day bill recorded N20.27 billion in subscriptions, with N10.45 billion allotted at a stop rate of 15.79%.

Why This Matters

The DMO decision to reject nearly N1.84 trillion in bids underscores its priority of controlling borrowing costs amid elevated system liquidity. Lower stop rates reduce federal government interest expense, but tight allotments may signal constrained cash flow needs or shifting investor sentiment. With banking-system liquidity at N8.59 trillion, supported by N2.13 trillion in OMO maturities, the auction demonstrates the DMO willingness to limit allotments rather than accept higher yields. This marks the second consecutive auction where the DMO left most bids unallotted, a shift from earlier quarterly patterns where larger amounts were accepted.

Key Takeaways

  • Only 8.89% of the advertised N800 billion was allotted, leaving over 96% of investor subscriptions unfilled.
  • Stop rates declined across all tenors: the 91-day rate fell to 15.40%, the 182-day to 15.79%, and the 364-day to 15.80%.
  • The 364-day bill accounted for nearly all of the N1.837 trillion in unallotted subscriptions.
  • Banking liquidity surged to N8.59 trillion before the auction, yet the DMO still capped allotments to curb higher borrowing costs.
  • This marks the second consecutive auction where the DMO left most bids unallotted, a shift from earlier quarterly patterns.

Conclusion

With stop rates trending lower and substantial bids rejected, the October 28 auction signals a deliberate DMO strategy to manage issuance costs amid ample liquidity. Whether this approach persists in future sessions will depend on market dynamics, monetary policy signals, and the balance between investor demand and fiscal needs.
