The Central Bank of Nigeria (CBN) absorbed N3.04 trillion from the banking system through a single Open Market Operations (OMO) auction conducted on June 5, 2026, as investor demand across three tenors significantly exceeded the N600 billion offered by the apex bank.
According to an analysis of CBN OMO auction results and daily financial market data between June 2 and June 5, 2026, total subscriptions reached N3.275 trillion, representing an oversubscription rate of 5.46 times the amount offered. This development underscores the CBN’s continued aggressive liquidity sterilisation strategy, even as excess liquidity in the banking system showed some signs of easing during the review period.
The latest auction follows two major OMO sessions in May that collectively absorbed trillions of naira from the financial system. A breakdown of the June 2 OMO auction results shows exceptionally strong investor appetite, particularly for longer-dated instruments. The figures indicate that investors continue to channel excess liquidity into CBN sterilisation instruments, with strong preference for longer-tenor securities despite lower yields. The 133-day bill’s 12.4-times oversubscription ratio highlights growing investor willingness to lock in funds for extended periods amid expectations of sustained monetary tightening.
Additional market activity during the week further reduced liquidity within the financial system. The data also shows that the CBN continues to rely primarily on OMO auctions and primary market operations for liquidity management during the current monetary policy cycle. Recent projections indicate that substantial liquidity inflows are expected to enter the banking system during June despite the CBN’s aggressive sterilisation efforts.
However, the N4.74 trillion SDF balance recorded on June 5 suggests that excess liquidity remains a defining feature of Nigeria’s banking system despite the scale of recent liquidity mop-ups.
