Broad money rises ₦7.51tn in one month as the CBN’s interest-rate reduction reshapes the monetary policy environment
Nigeria’s broad money supply rose to ₦146.6 trillion in September 2026, increasing by ₦7.51 trillion in one month as liquidity within the financial system continued to expand.
Data from the Central Bank of Nigeria (CBN) showed that broad money, measured as M3, increased by 5.4 per cent from ₦139.09 trillion in August, bringing the cumulative expansion since January to ₦22.65 trillion.
The latest figure represents an 18.3 per cent increase from the ₦123.95 trillion recorded at the beginning of the year, highlighting the substantial growth in monetary aggregates over the period.
The September increase followed a period of sustained expansion, with broad money rising from ₦125.19 trillion in April to ₦129.54 trillion in May and ₦133.27 trillion in June. It subsequently climbed to approximately ₦139.1 trillion in July before remaining virtually unchanged in August and surging in September.
The latest movement places money supply growth firmly within the debate over inflation management, banking-system liquidity and the effectiveness of monetary policy.
The expansion comes after the CBN reduced its benchmark Monetary Policy Rate (MPR) to 23 per cent from 26.5 per cent in September, signalling a shift in its policy stance as economic conditions evolved.
Although an interest-rate reduction can lower borrowing costs over time and support credit creation, the relationship between monetary policy and money supply is not automatic. Bank lending, government transactions, deposit movements and other financial flows also influence the volume of money circulating in the economy.
Narrow money also increases
The CBN data further showed that narrow money, comprising currency in circulation and highly liquid deposits, increased to ₦44.05 trillion in September from ₦43.11 trillion in August.
Currency held outside the banking system also rose, reaching ₦4.92 trillion compared with ₦4.87 trillion in the preceding month.
The increase suggests that both broader monetary aggregates and immediately accessible funds expanded during the period, although the figures alone do not establish how much of the additional liquidity was directed towards consumption, investment or productive lending.
For policymakers, the composition and destination of money growth are important in determining its implications for inflation and economic activity.
An increase in money supply can support spending and business expansion where credit reaches productive sectors. However, if liquidity grows faster than the economy’s capacity to produce goods and services, it can contribute to inflationary pressure.
The implications also depend on exchange-rate movements, import costs, consumer demand and the pace of domestic production.
Implications for businesses and investors
For businesses, the direction of monetary policy will remain important in determining borrowing costs, working-capital availability and investment decisions.
A lower policy rate could eventually support more affordable financing, although lending rates may adjust gradually depending on banks’ funding costs, perceived credit risks and prevailing market conditions.
For investors, rising money supply can influence demand for equities, bonds and other financial assets, but its impact will depend on inflation expectations, real interest rates and the outlook for corporate earnings.
The CBN will therefore need to assess the increase in monetary aggregates alongside inflation, credit growth and broader economic indicators to determine whether financial conditions remain consistent with price stability.
The September figures underline the importance of monitoring not only the amount of money circulating in the economy but also how effectively it supports production, investment and sustainable growth.
