The move was after the apex bank addressed recent misinformation about the validity of the old N1000, N500, and N200 banknotes still in circulation.

A statement signed by Sidi Ali Hakama, acting director of corporate communications, reaffirmed that these denominations remained valid legal tender in line with a Supreme Court ruling issued on November 29, 2023, and warned against hoarding.

Following the clarification, CBN in a circular signed by the Acting Director of the Currency Operations Department, Mohammed Olayemi on Friday, said it was concerned about the increasing prevalence of mint naira notes being traded by hawkers.

CBN described the practice as impeding efficient and effective cash distribution to customers and the general public.

The circular, which referred to an earlier directive dated November 13, 2024, highlighted the apex bank’s determination to address the commodification of the naira.

Under the directive, any branch of a financial institution found culpable will face a penalty of N150m for the first violation.

Subsequent infractions, the CBN warned, would attract stricter sanctions under the provisions of the Banks and Other Financial Institutions Act (BOFIA) 2020.

To ensure compliance, the apex bank stated that it would increase periodic spot checks in banking halls and ATMs while deploying mystery shoppers to uncover illicit cash hawking spots across the country.

The circular read, “The CBN has noted with dismay the prevalence of illicit flow of mint banknotes to currency hawkers and other unscrupulous economic agents that commodify Naira banknotes, thus impeding efficient and effective cash distribution to banks’ customers and the general public.

“CBN will continue to intensify the periodic spot checks to the banking halls/ATMs to review cash payouts to banks’ customers, as well as mystery shopping to all identified cash hawking spots across the country.

“In this regard, any erring deposit money banks or financial institutions that are culpable of facilitating, aiding, or abetting, by direct actions or inactions, the illicit flow of mint banknotes to currency hawkers and unscrupulous economic agents that commodify Naira banknotes shall be penalised at first instance N150,000,000.00 (One hundred and fifty million Naira) only, per erring branch, and at later instances, apply the full weight of relevant provisions of BOFIA 2020.”

The CBN further urged DMBs to strengthen controls, processes, and procedures around their Cash Management Centres, branches, and teller operations to prevent their systems from being exploited for illegal transactions.
