Main Story
The Central Bank of Nigeria (CBN) sold approximately ₦2 trillion worth of Open Market Operation (OMO) bills at its latest primary market auction, following strong demand from foreign portfolio investors and deposit money banks.
The apex bank had initially offered ₦600 billion across 32-day, 116-day, and 137-day tenor instruments as part of efforts to reduce excess liquidity within the financial system and stabilise monetary conditions.
However, the auction recorded subscriptions exceeding ₦2.1 trillion, reflecting sustained investor appetite for high-yield fixed-income securities amid elevated interest rates and persistent inflationary pressures in the economy.
Investment banking firms reported that the CBN eventually allotted around ₦2 trillion worth of bills. The 32-day instrument cleared at a stop rate of 21.58%, while the 116-day and 137-day papers settled at 20.20% and 19.98% respectively.
The aggressive mop-up exercise comes as the monetary authority continues tightening liquidity conditions in a bid to curb inflation and support naira stability in the foreign exchange market.
Analysts said the strong participation by foreign portfolio investors also signals renewed confidence in Nigeria’s fixed-income market following recent monetary policy tightening and improved FX liquidity conditions.
The development follows a series of elevated OMO auctions by the CBN in recent months as the banking system continues to witness strong liquidity inflows from maturing securities and fiscal disbursements.
The Issues
The latest OMO sale highlights the CBN’s continued reliance on aggressive liquidity management to contain inflationary pressures, which remain elevated despite successive monetary tightening measures.
Nigeria’s high-yield environment has increasingly attracted offshore investors seeking returns in emerging markets. However, analysts warn that sustained dependence on short-term foreign inflows could expose the financial system to volatility if global risk sentiment weakens.
The large oversubscription also underscores excess liquidity conditions in the banking sector, driven partly by maturing government securities and robust system liquidity. Monetary authorities have repeatedly used OMO auctions to absorb surplus funds and prevent pressure on inflation and the foreign exchange market.
What’s Being Said
“The strong demand reflects investor confidence in the fixed-income market and continued appetite for attractive yields in the current rate environment,” analysts at CSL Stockbrokers said in a market note.
“The CBN remains focused on liquidity sterilisation as part of broader efforts to maintain price stability and manage inflation expectations,” analysts at an investment banking firm noted.
What’s Next
- Investors will monitor the CBN’s next liquidity management operations and possible adjustments to stop rates
- Market participants are awaiting the next Monetary Policy Committee meeting for guidance on interest rate direction
- Analysts expect continued aggressive OMO activity if system liquidity remains elevated in the coming weeks
The Bottom Line: The CBN’s ability to attract more than ₦2 trillion in subscriptions despite a smaller initial offer signals continued investor confidence in Nigeria’s high-yield fixed-income market. However, the scale of liquidity mop-up also reflects the growing challenge facing monetary authorities as they attempt to balance inflation control, exchange rate stability, and economic growth.
