The Central Bank of Nigeria — Monetary Policy, Liquidity Management, and Exchange Rate Reform

A Central Bank in Transition

The Central Bank of Nigeria (CBN) has undergone dramatic changes since the appointment of Governor Olayemi Cardoso in 2023. The previous governor, Godwin Emefiele, was suspended and arrested amid allegations of corruption and mismanagement, leaving a legacy of multiple exchange rates, Ways and Means advances to the government, and depleted reserves.

The Emefiele Legacy

Under Emefiele (2014-2023), the CBN pursued unconventional policies:

• Multiple exchange rates: Different rates for different transactions, creating arbitrage opportunities and corruption
• Ways and Means: Direct monetization of fiscal deficits, reaching approximately ₦23 trillion ($25 billion)
• Development finance: CBN directly funded agriculture, manufacturing, and other sectors — straying from conventional central banking

The Cardoso Reforms

Governor Cardoso has implemented significant reforms:

• Exchange rate unification: Collapsed multiple rates into a single market-determined exchange rate, causing the naira to devalue approximately 40%
• Interest rate hikes: Raised the policy rate to 26-27% to combat inflation running at 25-30%
• Ending Ways and Means: Stopped direct government financing and began securitizing existing advances
• Reserve rebuild: Working to rebuild foreign exchange reserves from approximately $33 billion

Monetary Policy Challenges

The CBN faces difficult trade-offs:

• Inflation vs growth: High interest rates combat inflation but constrain private sector credit
• Exchange rate vs competitiveness: A floating naira improves transparency but raises import costs
• Financial stability: Banking sector stress from currency devaluation and bad loans
• IMF engagement: Increased IMF involvement with conditionality on monetary policy and exchange rate reform

Broader Significance

These dynamics illustrate the broader challenge facing developing economies: building resilient financial systems while managing external pressures from international capital flows, sovereign debt obligations, and the evolving global monetary framework set by monetary policy and central banking in advanced economies. The interplay between domestic financial deepening and external vulnerabilities remains the central tension in emerging market development.
