What foreign exchange means
Foreign exchange is the buying and selling of one currency for another.
For a Nigerian business it arises constantly: paying a foreign supplier, receiving export proceeds, paying a foreign software subscription, remitting a dividend to a foreign shareholder, servicing a foreign currency loan, or funding a child's education abroad.
It is a regulated activity. The Central Bank of Nigeria supervises the market, authorised dealer banks are the channel through which transactions run, and the framework attaches documentation to each type of transaction.
The documentation exists to establish what the currency is for, because access to foreign exchange through official channels has at various times been rationed and prioritised by transaction type.
The honest position on detail is that this framework has changed more often than any other area of Nigerian financial regulation. Windows have been created, merged and abolished, rates have been managed and unified, and eligibility lists have been revised. Any specific rate or rule should be confirmed with an authorised dealer bank rather than taken from a published description.
How it is used
The documentation follows the transaction type, and the forms are the practical language of Nigerian foreign exchange.
A Form M is opened through an authorised dealer bank before goods are imported. It registers the import transaction and links it to the foreign exchange arrangements, and it must match the bill of lading, the invoice and the eventual customs documentation.
A Form A supports payments for services and other invisible transactions: professional fees, subscriptions, education and medical expenses abroad.
A Form NXP is used for exports, registering the transaction and supporting repatriation of proceeds.
A certificate of capital importation evidences foreign capital coming in through an authorised dealer bank, and it is what supports later repatriation of dividends, sale proceeds and loan repayments.
For a business, the practical discipline is to establish the documentation route before committing to a transaction rather than afterwards. A company that contracts to pay a foreign supplier and then discovers what documentation is required, and how long it takes, has created a problem it could have planned around.
Key features
- Regulated by the Central Bank of Nigeria through authorised dealer banks
- Documentation requirements attach to each transaction type
- Form M for imports, Form A for services, Form NXP for exports
- Certificates of capital importation support repatriation of inflows
- The framework has changed repeatedly and details date quickly
- Confirm current requirements with an authorised dealer bank
How this works in Nigeria
Three practical realities shape how Nigerian businesses handle currency risk.
The first is that contracts must allocate exchange rate risk explicitly. A supply agreement priced in dollars and payable in naira at the prevailing rate transfers the whole of that risk to the buyer. One priced in naira transfers it to the seller. Neither is wrong, and the decision should be conscious rather than default. Quotations should also carry short validity periods for the same reason.
The second is documentation timing. Import transactions run on a chain: Form M, then shipment, then the Pre Arrival Assessment Report, then customs clearance. A gap or a mismatch anywhere in that chain produces delay, and delay in Nigerian ports means demurrage.
The third is the capital importation point for anybody bringing money in. Capital that arrives without a certificate has no documented route out, and that surfaces at exit rather than at entry.
On rates and eligibility specifically, the framework has been through several reconfigurations, including the unification of previously separate windows. Anybody planning a transaction should ask their bank what applies now, in writing, rather than relying on an article.
Parallel market transactions sit outside the official framework and carry their own risks, including the absence of documentation that later repatriation depends on.
Form M vs Form A vs certificate of capital importation
Three pieces of Nigerian foreign exchange documentation covering three different flows.
A Form M covers goods coming in. It is opened through an authorised dealer bank before shipment, registers the import, and has to match the bill of lading, the invoice and the customs documentation.
A Form A covers services and invisible transactions going out: professional fees, subscriptions, education and medical costs abroad. It documents the purpose of the payment.
A certificate of capital importation covers investment coming in. It is issued by the bank that received the inflow, and it is what supports remitting dividends, sale proceeds and loan repayments out later.
A business importing goods, paying a foreign consultant and taking foreign investment needs all three, from the same bank, and each one is easiest to arrange at the time of the transaction rather than afterwards.
Limits and risks
Access through official channels has been constrained at various times, and documentation does not guarantee availability.
The framework also changes, which makes planning difficult and makes any written description date quickly.
Documentation adds time to transactions, and businesses working to tight delivery schedules need to build it into the timetable.
Parallel market transactions avoid the process and forfeit the documentation, which becomes a problem when repatriation or evidence of source is needed.
And exchange rate volatility is a commercial risk no documentation addresses. That is managed in the contract, through pricing, validity periods and allocation clauses, rather than through the regulatory framework.
Worth knowing
Say in every contract with a foreign element which currency the price is in and who bears the rate risk. Nigerian suppliers and buyers agree a figure without stating whether it is fixed in naira or converted at the prevailing rate, and a rate movement then turns a profitable contract into a loss for whoever was left holding it.
Questions people ask
Who regulates foreign exchange in Nigeria?
The Central Bank of Nigeria, with transactions running through authorised dealer banks. Documentation requirements attach to each transaction type and are handled through those banks.
What is a Form M?
The document opened through an authorised dealer bank before goods are imported. It registers the import transaction and must match the bill of lading, the invoice and the customs documentation.
What is a Form A used for?
Payments for services and other invisible transactions, such as professional fees, subscriptions, and education or medical expenses abroad.
Why do I need a certificate of capital importation?
Because it evidences that foreign capital came in through an authorised dealer bank, and it is what supports remitting dividends, sale proceeds and loan repayments out later. Money that arrived without one has no documented route out.
Have the rules changed?
Repeatedly. Windows have been created, merged and abolished and eligibility lists revised, so any specific rate or requirement should be confirmed with an authorised dealer bank rather than taken from a published description.
How should a contract handle exchange rate risk?
Explicitly. State the currency of the price and whether payment is fixed in naira or converted at the prevailing rate, and keep quotation validity periods short where inputs are imported.
