The Central Bank of Nigeria (CBN), acting through the Debt Management Office (DMO), has lowered the stop rate on its benchmark 364-day Nigerian Treasury Bill (NTB) following a midweek primary market auction. Driven by strong institutional demand for long-duration naira assets, investors flooded the auction with bids that exceeded the initial offer by more than five times.
Surging Liquidity Triggers Massive Oversubscription
The DMO brought a combined offer of N700 billion across three standard tenors—91-day, 182-day, and 364-day bills—to the primary market. In response, total investor subscriptions printed at an extraordinary N3.618 trillion. Demonstrating disciplined debt management, the monetary authority ultimately allotted N1.20 trillion across all maturities while rejecting roughly N2.42 trillion in excess bids.
Auction Breakdown by Tenor
Investor appetite was overwhelmingly concentrated at the longer end of the yield curve, as market participants sought to secure attractive returns ahead of expected rate shifts:
- 91-Day Bills: With N100 billion on offer, total subscriptions reached N135.74 billion. The CBN allocated N130.72 billion, holding the stop rate unchanged at 16.30%.
- 182-Day Bills: Against an initial offer of N100 billion, subscriptions totaled N104.74 billion. The CBN allotted N99.18 billion, maintaining the rate steady at 16.50%.
- 364-Day Bills: The 1-year maturity recorded massive demand, attracting N3.378 trillion in total bids. To absorb the surge in liquidity, the CBN allotted N1.017 trillion while reducing the spot rate by 31 basis points from 17.66% down to 17.35%.
Macroeconomic Drivers Behind the Yield Cut
In a analysis of market conditions, investment firm Meristem Securities Limited highlighted several factors influencing the clearing rates at the midweek auction. Fixed-income analysts noted that secondary market yields have consistently trended lower in recent trading sessions, bolstered by a slight moderation in headline inflation to 15.91% year-on-year in June from 15.93% in May.
This easing inflation trend strengthened the case for reduced primary market rates, particularly on the 1-year paper. Although stop rates were kept mostly stable at recent Open Market Operations (OMO) and Federal Government of Nigeria (FGN) bond auctions, the massive liquidity pool competing for 364-day bills provided the central bank ample flexibility to lower borrowing costs without risking auction failure.
Market Implications for Fixed-Income Investors
The significant demand for long-tenor government paper underscores high system liquidity and a preference among institutional investors to lock in yields. With secondary yields compressing and inflation showing signs of stabilization, investors should anticipate potential downward pressure on primary market yields in upcoming auctions.
