The Central Bank of Nigeria (CBN) has cancelled the N700bn Treasury Bills (T-bills) auction originally scheduled for August 5, 2026, as liquidity conditions in the banking system tightened significantly following aggressive Open Market Operations (OMO).
The cancellation came shortly after the apex bank withdrew a combined N4.69tn from the banking system through two consecutive OMO sessions. The move has raised concerns among market participants about the impact of continued liquidity sterilisation on funds available to banks and other financial institutions.
On August 3, the CBN absorbed N2.52tn through the sale of a 141-day OMO bill. The following day, August 4, it withdrew another N2.17tn through 112-day and 113-day OMO bills.
The scale of the intervention over the two-day period appears to have influenced the decision to suspend the planned T-bills auction, as proceeding with another large government securities offering could have placed further pressure on liquidity in the financial system.
Although the CBN, acting on behalf of the Debt Management Office (DMO), did not publicly provide a specific reason for the cancellation, the timing of the decision suggests that liquidity conditions may have been a major consideration. Market participants have been closely monitoring the extent to which repeated OMO operations are affecting available funds and short-term interest rates.
The cancelled auction was initially designed to raise N700bn across three maturities: 91-day, 182-day and 364-day Treasury Bills. Settlement for the transaction had been scheduled for August 6.
The latest OMO intervention also adds to the substantial amount of liquidity already withdrawn by the CBN in recent weeks. In July alone, the apex bank sterilised N7.18tn through OMO auctions. With the additional N4.69tn withdrawn in the first four days of August, the total liquidity mopped up through OMO operations in July and the first four days of August has now exceeded N11.8tn.
At the same time, demand for government securities has remained strong, providing another important factor in the current market environment. At the July 29 T-bills auction, the CBN allotted approximately N1.25tn, significantly above the initial N700bn offer.
The strong demand was largely concentrated around the 364-day Treasury Bill, highlighting investors' continued appetite for short-term government securities despite the increasingly tight liquidity conditions.
The situation presents the monetary and fiscal authorities with a delicate balancing act. While the government needs to raise funds through domestic borrowing to meet its financing requirements, the CBN must also manage liquidity in the banking system and prevent excessive tightening from creating broader pressures in the financial markets.
The cancelled auction forms part of the N5.8tn Treasury Bills issuance programme for the third quarter of 2026. The programme is expected to generate approximately N3.16tn in net new borrowing after accounting for bills that are due to mature during the period.
The August 5 auction was also one of six major N700bn issuance sessions included in the Q3 calendar. With the session now cancelled, attention is shifting to whether the N700bn will be rescheduled at a later date or incorporated into subsequent Treasury Bills auctions.
The CBN and DMO have indicated that the other auction dates contained in the third-quarter calendar remain unchanged. Investors will therefore be watching closely for further guidance on the treatment of the cancelled issuance and whether liquidity conditions improve enough to support future auctions at their planned sizes.
Analysts say the development could affect the pace of government borrowing through Treasury Bills if the banking system remains under pressure and the CBN continues to rely heavily on OMO operations to absorb excess liquidity.
For now, the cancellation underscores the growing interaction between the government's domestic borrowing needs and the CBN's monetary policy operations, with liquidity conditions likely to remain a key factor shaping the Nigerian fixed-income market in the weeks ahead.
