Nigeria's broad money supply surged to N146.6 trillion in September 2026, marking an increase of N7.51 trillion from the previous month. This growth, reported by the Central Bank of Nigeria (CBN), reflects a 5.4 percent rise from N139.09 trillion in August, illustrating a continued expansion of liquidity within the financial system.

Since the beginning of the year, the total growth in money supply has reached N22.65 trillion, representing an 18.3 percent increase from N123.95 trillion recorded in January. The significant rise in September follows a pivotal decision by the CBN to reduce its benchmark interest rate from 26.5 percent to 23 percent during its Monetary Policy Committee (MPC) meeting in September. This adjustment, the largest since December 2006, aims to stimulate economic activity amid ongoing inflationary pressures.

The CBN's data also indicates that narrow money, which includes cash and highly liquid deposits, rose from N43.11 trillion in August to N44.05 trillion in September. Additionally, the amount of currency held outside banks saw a slight increase, growing from N4.87 trillion to N4.92 trillion in the same period.

Broad money supply encompasses various forms of liquid assets, including cash, demand deposits, savings, time deposits, and foreign currency deposits. While the growth in money supply suggests an increase in funds circulating within the financial system, it does not guarantee that these funds will directly translate into consumer spending.

The MPC's recent decision to lower the Monetary Policy Rate was made against a backdrop of balancing inflation control with the need to foster economic growth. In previous meetings, the committee had maintained the rate at 26.5 percent, weighing the implications of high inflation against the necessity of supporting economic activity. The rate was previously cut by 50 basis points to 27 percent in September 2025, but remained unchanged in November of the same year.

The latest increase in money supply raises important questions regarding its potential impact on inflation, lending practices, and overall economic growth. Analysts will be closely monitoring how much of this additional liquidity will flow into credit and consumer spending, as these factors will significantly influence the economic landscape in the coming months.
