Nigeria’s One-Year T-Bill Stop Rate Falls On Heavy Demand: Liquidity Splits The Local Curve

Nigeria’s 364-day Treasury bill cleared at 17.15% at the August 26 auction, 44 basis points below the previous 17.59% stop rate. Demand reached approximately N3.63 trillion against N500 billion offered, indicating strong primary-market interest in the one-year tenor. At the same time, average secondary-market Treasury-bill yields rose during the week as investors repositioned ahead of auctions, leaving the local fixed-income market with contrasting signals across venues and maturities.

The transmission is concentrated in Nigeria’s local funding curve. The lower stop rate reduces the marginal clearing cost for the 364-day government instrument, while firmer secondary-market yields point to less uniform liquidity between the auction and secondary markets. That distinction matters for domestic refinancing conditions: the government’s primary funding cost and mark-to-market conditions for existing bills are not moving in lockstep. Nigerian corporates funding through local markets face the same curve differentiation rather than a single, uniform decline in borrowing costs.

The evidence does not establish a corresponding move in Nigeria’s external Eurobond spread. The event is therefore more directly relevant to naira fixed income, Treasury-bill pricing and local corporate funding than to dollar-denominated sovereign credit. It also does not by itself demonstrate a change in currency conditions, reserve adequacy or the cost of external debt service.

The next signal is whether strong demand remains concentrated at the primary auction while secondary-market yields stay firmer. Persistent divergence would indicate segmented liquidity across Nigeria’s local curve; convergence would provide a cleaner read-through from auction demand into broader domestic rates.
