The Central Bank of Nigeria (CBN) has scheduled a N5.8 trillion ($3.7 billion) Treasury bill auction for the third quarter of 2026, marking the most significant liquidity mop-up operation in the country this year.

The issuance comes as N2.64 trillion in securities mature, requiring the central bank to manage substantial rollover pressure while simultaneously tightening financial conditions.

21 trillion in May 2026, according to data cited by Nairametrics.

This aggressive auction calendar underscores the CBN's continued effort to absorb excess liquidity from the banking system.

The move is particularly notable given that Nigeria's broad money supply expanded to N129.21 trillion in May 2026, according to data cited by Nairametrics.

The divergence between the growing money supply and the central bank's tightening stance highlights the persistent inflationary pressures and monetary management challenges facing the West African economy.

For investors in Nigerian fixed-income markets, the scale of the upcoming auction suggests potential upward pressure on short-term yields as the CBN competes for available funds.
