CURRENCY ARBITRAGE IN NIGERIA: THE IMPORTANT THING YOU NEED TO KNOW ABOUT SELLING MINT NOTES

by Ekosolicitors

Introduction to currency arbitrage in nigeria

According to Black’s Law Dictionary, money is a general, indefinite term for the measure and representative of value, currency, or the circulating medium.

Money is ordinarily regarded as a medium of exchange, a unit of account and a store of value. In Nigeria, the Naira is the official unit of currency and serves as legal tender for the payment of obligations. However, a practice has emerged in which individuals obtain newly issued or “mint” Naira notes and resell them to members of the public at prices above their face value. For instance, a person may possess ₦100,000 in fresh ₦1,000 notes but demand ₦105,000 from another person in exchange for the same ₦100,000. This practice is sometimes described as the business of selling mint notes or currency arbitrage.

Although the transaction may appear to be a simple commercial arrangement between willing parties, it raises an important legal question: Can a person lawfully sell or trade in Nigerian currency for a premium?

The answer requires an examination of the Central Bank of Nigeria Act 2007, particularly the provisions regulating the issuance, legal tender status and treatment of Naira notes and coins.

The Naira as Nigeria’s Currency arbitrage in Nigeria

The starting point is Section 15 of the Central Bank of Nigeria Act 2007. The provision establishes the Naira as the unit of currency in Nigeria and provides for its division into one hundred kobo.

The Act also places the issuance of Nigerian currency under the control of the Central Bank of Nigeria. Section 17 provides that the Bank has the sole right of issuing currency notes and coins throughout Nigeria. It further prohibits other persons or authorities from issuing instruments intended to circulate as currency or legal tender.

This statutory arrangement is important because it demonstrates that the Naira is not an ordinary commodity that private individuals are free to manufacture, issue or commercially manipulate. Its issuance and regulation are matters entrusted to the Central Bank.

Legal Tender and the Face Value of Currency

Section 20(1) of the Act provides that currency notes issued by the Bank are legal tender in Nigeria at their face value for the payment of any amount. Coins issued by the Bank are similarly legal tender, subject to the conditions contained in the Act.

The concept of face value is significant to the discussion of mint notes. A ₦1,000 note remains a ₦1,000 note as far as its monetary value is concerned, irrespective of whether it is old, worn, freshly printed or in perfect condition.

However, this does not necessarily mean that every transaction involving physical currency is prohibited. The critical issue is whether a person is selling or otherwise trading in the Naira itself, rather than merely using it as a means of payment in an ordinary transaction.

The Prohibition Against Trading in Naira Notes

The principal provision for this discussion is Section 21 of the Central Bank of Nigeria Act 2007, headed “Tampering with or trading in notes and coins.”

Section 21(1) provides an offence in relation to tampering with coins or notes issued by the Bank and prescribes imprisonment and/or a fine upon conviction. Section 21(2) explains circumstances in which a coin or note is deemed to have been tampered with, including deliberate acts such as defacing, mutilating, splitting, tearing, writing on or otherwise abusing the currency.

More directly relevant to the business of selling mint notes is Section 21(4). It provides that it is an offence for a person, under the section, “to hawk, sell or otherwise trade in the Naira notes, coins or any other note issued by the Bank.”

This provision is the strongest statutory basis for questioning the legality of a business model built around selling Naira notes themselves.

Application to the Business of Mint Notes

Consider a person who obtains ₦500,000 in freshly issued Naira notes and advertises them for sale. The person may tell prospective customers:

“₦500,000 mint notes available for ₦515,000.”

The customer receives currency worth ₦500,000 but pays ₦515,000. The ₦15,000 difference represents the seller’s premium.

From an economic perspective, the seller is attempting to profit from the difference between the demand for fresh notes and their nominal value. This resembles arbitrage because the seller seeks to exploit a difference in perceived or market value.

From the perspective of Section 21(4), however, the difficulty is that the underlying subject of the transaction is the Naira notes themselves. The Act expressly prohibits a person from hawking, selling or otherwise trading in Naira notes, coins or other notes issued by the Bank.

Consequently, describing the activity as “mint-note business” or “currency arbitrage” does not, by itself, make it lawful. The substance of the transaction is more important than the label attached to it.

Currency Arbitrage and Ordinary Foreign Exchange

It is also important to distinguish the alleged business of selling mint Naira notes from legitimate foreign-exchange transactions.

The CBN Act recognises the Bank’s role in relation to foreign currency. For example, Section 26 provides that the Bank may issue and redeem Nigerian currency against other currencies eligible for inclusion in the reserve of external assets under the Act. Section 28 also recognises certain transactions involving foreign currencies and securities within the Bank’s statutory functions.

Therefore, currency arbitrage in the ordinary foreign-exchange sense should not automatically be equated with selling physical Naira notes. A transaction involving the lawful exchange of foreign currencies within the applicable regulatory framework is conceptually different from a person purchasing or obtaining Naira notes and reselling those notes as a commodity at a premium.

Why the Law Regulates Trading in Currency

The prohibition serves broader monetary and public-policy objectives. Currency must remain reliable, recognisable and subject to the control of the monetary authority. Unregulated trading in physical currency could create undesirable practices surrounding the distribution and availability of cash.

The statutory scheme places responsibility for issuing and regulating currency on the Central Bank. Section 17 gives the Bank the sole right of issuing currency notes and coins, while Section 18 gives it responsibility for arranging their printing, minting, re-issuance and exchange.

The law therefore treats currency differently from an ordinary product such as clothing, electronics or food. A person does not acquire an unrestricted commercial right to deal in the Naira merely because he or she is in physical possession of the notes.

Penalty and Enforcement currency arbitrage in nigeria

The Act provides criminal consequences for conduct falling within Section 21. For tampering offences under Section 21(1), a convicted person may be liable to imprisonment for a term of not less than six months or a fine of not less than ₦50,000, or both fine and imprisonment.

The specific penalty applicable to the offence under Section 21(4) should, however, be considered with care alongside the applicable statutory provisions and any subsequent amendments or legislation. The important point for the legal analysis is that the Act expressly characterises hawking, selling or otherwise trading in Naira notes and coins as an offence.

Conclusion to currency arbitrage in nigeria

The business of selling mint Naira notes raises a significant question about the boundary between ordinary commercial activity and conduct regulated by monetary law. While a person may physically possess Naira notes, that possession does not necessarily confer a legal right to treat the notes themselves as merchandise.

Under Section 21(4) of the Central Bank of Nigeria Act 2007, hawking, selling or otherwise trading in Naira notes or coins issued by the Central Bank constitutes an offence. This provision therefore creates a strong legal basis for challenging a business model in which individuals obtain fresh Naira notes and resell them at a premium merely because customers are willing to pay more for their condition or convenience.

Ultimately, the key distinction is between using the Naira as money and treating the Naira itself as a commodity for resale. The former is the ordinary function of currency; the latter is precisely the type of conduct that Section 21(4) seeks to regulate.

Therefore, “mint” does not change the legal nature of the Naira: a ₦1,000 note remains ₦1,000 in face value, and the commercial trading of the note itself is subject to the prohibition contained in the CBN Act.
