Nearly half a trillion naira that had been sitting outside Nigeria’s banking system disappeared from that category during the first half of 2026, offering an early sign that more physical cash may be moving back into formal financial channels.
Currency held outside banks fell from ₦5.41 trillion in December 2025 to ₦4.92 trillion in June 2026, a reduction of ₦485.8 billion, or 8.98%. The June figure was the lowest in seven months and marked a sharp reversal from the high level of cash Nigerians were holding at the end of last year.
₦485.8 billion decline in currency outside banks does not mean commercial banks received exactly ₦485.8 billion in additional customer deposits.
Total currency in circulation also fell during the period, meaning part of the decline reflects a reduction in the overall volume of physical naira circulating in the economy, while another portion reflects cash being retained within the banking system.
Nigerians Are Holding Less Cash Outside Banks
The decline did not happen in a single month. Currency outside banks dropped from ₦5.41 trillion in December to ₦5.25 trillion in January and ₦5.19 trillion in February before falling further to ₦5.08 trillion in April. The available CBN series does not include a March figure, while May briefly interrupted the trend as cash outside banks climbed back to ₦5.19 trillion.
Currency outside banks fell by about ₦271 billion from May to ₦4.92 trillion, a monthly contraction of 5.22%. That brought the figure close to the ₦4.91 trillion recorded in November 2025 and made June the lowest level since then.
Total currency in circulation declined from ₦5.73 trillion in December 2025 to ₦5.52 trillion in June, a reduction of about ₦209.56 billion. Currency outside banks, however, fell by ₦485.8 billion over approximately the same period.
Using the reported figures, roughly ₦320 billion of the ₦5.73 trillion in circulation was inside banks in December.
By June, about ₦600 billion of the ₦5.52 trillion in circulation was inside the banking system. The exact values depend on the underlying unrounded CBN data, but the direction is clear: banks were holding a considerably larger share of Nigeria’s physical currency by June than they were at the end of 2025.
Why ₦486bn Does Not Mean ₦486bn in New Deposits
Currency outside banks measures physical notes and coins held outside deposit money banks. When that figure falls, cash can be deposited with banks, retained in bank vaults, returned through the currency management system or removed from circulation. The indicator alone does not show how much became household deposits, business deposits or lendable funds.
What can be established is that the proportion of physical currency outside banks has declined.
In December, 94.33% of currency in circulation was outside the banking system. By June, that had fallen to 89.11%, meaning the share held within banks rose from 5.67% to 10.89%. In May alone, about 91.27% of physical currency had still been outside banks, showing that much of the improvement occurred in June.
Money inside the banking system is easier to move electronically, monitor within the financial system and potentially channel through savings, payments and credit. A lower proportion of cash outside banks can therefore improve the connection between economic activity and the financial institutions through which monetary policy operates.
What More Cash Inside Banks Could Mean
For banks, keeping a larger share of money within formal financial channels could strengthen their role as financial intermediaries. Deposits provide part of the funding banks use to support loans and other assets, while digital transactions also generate information that can help financial institutions understand customer behaviour and develop financial products.
For the CBN, there is a monetary policy consideration. When an overwhelming share of physical cash is outside banks, changes in banking-sector liquidity conditions do not necessarily capture all the money being used across the economy.
Bringing more transactions and savings into formal channels can make policy transmission more effective because a greater share of economic activity becomes connected to regulated financial institutions.
There is also a payments opportunity. Nigeria already has a large fintech and electronic payments market, but cash remains deeply embedded in everyday commerce.
Reducing its dominance is therefore unlikely to happen simply because more payment apps exist. Consumers and businesses need digital payments that are reliable, affordable and trusted enough to replace cash even for small transactions.
The CBN’s 2028 vision recognises that challenge. Beyond reducing cash dependence, it focuses on stronger infrastructure, wider financial inclusion, consumer protection, interoperability and innovation as foundations for expanding digital transactions.
