The currency in circulation in the country rose by N129bn to N2.97tn in October from N2.84tn in September, according to the figures from the Central Bank of Nigeria.
The currency in circulation had fallen to N2.78tn in August from N2.81tn in July.

The CBN said, “The currency in circulation increased by N465.47bn or 19.06 per cent to N2.91tn in 2020, compared with N2.44tn in 2019.
“In 2020, there were higher withdrawals by DMBs than deposits, due to the panic need to hold cash to deal with the emergencies and reduced banking hours due to restrictions to curb spread of the pandemic.”
The bank said to maintain public confidence and ensure integrity of circulated notes in the economy, it developed and unveiled a clean note policy and banknote fitness guidelines in 2018.
The guidelines outlined details of quarterly and yearly activities towards the achievement of this objective.
According to the CBN, the clean note policy encapsulates diverse currency management activities to preserve the integrity and maintain the quality of banknotes in circulation.
The policy provides that every newly printed and existing banknotes should conform to predefined standards before circulation and re-circulation in the economy.
Currency in circulation is defined as currency outside the vaults of the central bank – that is, all legal tender currency in the hands of the general public and in the vaults of the deposit money banks.
The CBN said it employed the “accounting/statistical/withdrawals and deposits approach” to compute the currency in circulation in the country.
It said this approach involved tracking the movements in currency in circulation on a transaction-by-transaction basis.
According to the CBN, for every withdrawal made by a DMB at one of CBN’s branches, an increase in CIC is recorded; and for every deposit made by a DMB at one of CBN’s branches, a decrease in CIC is recorded.
The transactions are all recorded in the CBN’s CIC account, and the balance on the account at any point in time represented the country’s currency in circulation.
