A Central Bank of Nigeria bill auction attracted bids of nearly ₦5 trillion against an offer of ₦600 billion, according to a BusinessDay Nigeria report published on 24 August 2026. The bills carried a reported yield of 20%.

The figures mean investors sought more than eight times the amount the CBN placed on offer. That imbalance highlights strong appetite for the bills while also showing that available supply was limited relative to the funds seeking an allocation.

BusinessDay described the offer as an open market operation, or OMO, auction and said the 20% yield came with a reinvestment problem. The evidence supplied for this report does not explain the nature of that problem, including when it may arise or which investors may be most affected. It is therefore not possible to assess its scale from the available information.

Other important auction details are also absent from the supplied evidence. These include the bills' maturity, the final amount allotted, the range of accepted bids and whether every successful investor received the same yield. No comparison with earlier CBN auctions was provided, leaving it unclear whether the level of demand or the 20% yield represented a change from recent sales.

What is clear is the size of the competition for the available bills: close to ₦5 trillion pursued a ₦600 billion offer. Further auction data would be needed to determine how much of that demand was accepted and to clarify why reinvesting proceeds could become difficult despite the stated yield.
