Explore the role of “monetary policies” “Central Bank of Nigeria” — how the CBN uses tools like interest rates, liquidity control, and inflation targeting to stabilise the economy and support sustainable growth.
Monetary policy is a powerful economic tool that central banks around the world use to maintain price stability, control inflation, support economic growth, and ensure a sound financial system. In Nigeria, the Central Bank of Nigeria (CBN) plays this role as the apex monetary authority, shaping policies that influence lending, inflation, exchange rates, and overall financial stability. This article explains in clear, user-friendly terms what monetary policy is, how the CBN formulates and applies it, and why these decisions matter to individuals, businesses, and investors in 2026.
What Are Monetary Policies?
At its core, monetary policy refers to the strategies and tools employed by a country’s central bank to control the supply of money and availability of credit in the economy. These policies aim to:
- Maintain price stability (keeping inflation at manageable levels)
- Support sustainable economic growth
- Stabilise the financial system
- Influence employment levels and investment conditions
Different central banks have slightly varied mandates, but the principles are similar internationally. Monetary policy often involves adjusting interest rates, reserve requirements, and market liquidity to align economic activity with national goals.
The Role of the Central Bank of Nigeria (CBN)
The Central Bank of Nigeria has constitutional authority to formulate and implement monetary policies that safeguard the naira’s value, ensure monetary stability, and support the government’s economic objectives. Its mandate is derived from several Central Bank of Nigeria Acts and amendments, which empower it to:
- Maintain monetary and price stability
- Promote a sound and efficient financial system
- Act as financial adviser and banker to the federal government
- Serve as lender of last resort to banks in distress
These functions position the CBN as a central figure in Nigeria’s economic architecture and a key driver of monetary policy decisions.
How Monetary Policy Works in Nigeria
Monetary policy in Nigeria is mainly conducted through the Monetary Policy Committee (MPC) — a group composed of the Governor, Deputy Governors, and appointed members — which meets regularly to assess economic conditions and decide on policy direction.
Key Tools of Monetary Policy
The CBN uses several instruments to guide economic outcomes:
1. Monetary Policy Rate (MPR)
This is the lead interest rate that influences borrowing costs throughout the economy. Adjusting the MPR can:
- Increase it to combat inflation by making borrowing more expensive
- Decrease it to stimulate growth by making credit cheaper
In 2025, the CBN cut the MPR from 27.5% to 27.0% — the first reduction since 2020 — reflecting easing inflation and a cautious attempt to support economic activity.
2. Cash Reserve Ratio (CRR)
This determines the percentage of deposits that banks must hold with the CBN rather than lend out. Higher CRR restricts loanable funds and helps control inflation, whereas lower CRR increases liquidity. Recent policy ranged from 50% to 45% for commercial banks, demonstrating the CBN’s efforts to balance liquidity and inflation risks.
3. Liquidity Ratio
The liquidity ratio dictates the portion of cash and liquid assets banks must maintain. This tool helps ensure financial stability and adequate credit flow to productive sectors.
4. Interest Rate Corridor and Standing Facilities
The interest rate corridor sets bounds around the MPR to guide interbank rates and market expectations, while standing facilities provide overnight borrowing or deposit options to manage short-term liquidity.
These tools are standard in central banking worldwide and help the CBN respond to shifting economic conditions.
Objectives of CBN Monetary Policy
Price Stability
A primary objective of monetary policy for Nigeria — as it is for most countries — is price stability. This translates to controlling inflation so that prices don’t rise too quickly, which preserves the naira’s purchasing power and protects savers and consumers.
Sustainable Economic Growth
Monetary policy also seeks to support an environment conducive to economic expansion. By aligning credit availability and interest rates with growth expectations, the CBN can help encourage investment and employment.
Exchange Rate Stability
Although influenced by external factors like oil prices and trade balances, the exchange rate of the naira is also shaped by monetary policy actions, especially through foreign exchange interventions and reserve management.
Financial System Stability
Ensuring that banks and other financial institutions remain solvent and that risks are managed responsibly is a key part of the CBN’s broader mandate. This function protects depositors and sustains confidence in the financial system.
Recent CBN Monetary Policy Decisions (2025–2026)
In recent Monetary Policy Committee meetings, the CBN has made several pivotal decisions reflecting current economic realities:
MPR Adjustments
- September 2025: MPR was reduced by 50 basis points to 27.0%, marking the first policy easing in years.
- November 2025: The MPC decided to hold the MPR at 27.0% to balance inflation control and economic support.
These actions reflect a shift from rigid tightening in previous years to a more accommodating stance as inflation pressures ease.
Reserve Requirements and Liquidity
The cash reserve ratio and liquidity ratio have been adjusted to maintain financial stability without stifling credit flow.
These decisions illustrate the CBN’s commitment to a balanced monetary policy that addresses inflation without overly restricting growth.
Why Monetary Policy Matters to You
Monetary policy might sound abstract, but its effects reach everyday life in Nigeria:
1. Borrowing Costs
Changes in the MPR influence lending rates on loans and mortgages. Higher rates can mean more expensive credit; lower rates can make credit more accessible.
2. Inflation and Prices
Monetary policy impacts inflation — controlling money supply can help keep prices stable, which matters directly for household budgets.
3. Savings and Investments
Interest rates determine returns on savings and risk-free investments. Policy shifts can make saving more or less attractive.
4. Exchange Rate and Remittances
Monetary policy and foreign reserves management influence the naira’s exchange rate, affecting the value of remittances and international trade.
Monetary Policy and Inflation Targeting
Traditionally, Nigeria’s monetary policy was more eclectic, but recent reforms signal a shift toward inflation targeting — a framework where the central bank sets explicit inflation goals and uses policy tools to achieve them. This approach provides greater transparency and helps anchor market expectations.
The International Monetary Fund (IMF) has supported such tightening measures, praising Nigeria for ditching deficit monetisation and focusing on governance and transparency in monetary policy.
This modernisation aims to strengthen Nigeria’s resilience against inflation shocks and external pressures.
Broader Monetary Reforms and CBN Initiatives
Beyond rate changes, the CBN is pursuing broader policy reforms:
Digital Payments and Financial Inclusion
Enhancing digital payment systems and fintech regulation to expand access and reduce cash dependency is part of Nigeria’s strategy to modernise its financial sector.
Collaboration With Fiscal Authorities
Stronger coordination between monetary and fiscal policy — such as revenue optimisation and disciplined public finance — helps make monetary policy more effective and sustainable.
