AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Nigerian banks often label foreign currency that arrives by wire as transferable, because its origin is documented by the sending bank, and cash lodged over the counter as non-transferable until its source is shown. Transferable funds can usually be sent abroad; cash-funded balances may be limited to cash withdrawal or conversion. The distinction comes from anti-money-laundering duties and each bank's policy under the CBN's FX framework, so ask your bank for its written rule.
Why banks draw the line
A wire from abroad comes with a paper trail: a sending bank that has already checked its customer, a named sender and a reference. Cash has none of that. Under the Money Laundering (Prevention and Prohibition) Act 2022, banks must know where customers' money comes from and report suspicious transactions, and cross-border cash above US$10,000 must be declared to Customs. Sending undocumented cash abroad would be the riskiest thing a bank could do with it, so many banks restrict it.
What each type usually allows
| Wire-received (transferable) | Cash-deposited (often non-transferable) | |
|---|---|---|
| Origin | Documented by the sending bank | Declared by you |
| Transfer abroad | Usually allowed with purpose and beneficiary | Often restricted unless source is proven |
| Cash withdrawal | Subject to the bank's cash stock | Usually allowed |
| Conversion to naira | Allowed at the bank's rate | Allowed at the bank's rate |
| Evidence that helps | Inward SWIFT advice | Customs declaration, sale receipt, bank slip |
The table describes common practice, not a uniform rule. Banks apply their own policies within the CBN's foreign exchange manual, and those policies differ.
Turning cash into a transferable balance
Some banks will treat cash as transferable once you show where it came from. Useful documents include:
- The Customs currency declaration form, if you brought the cash into Nigeria.
- A receipt or withdrawal slip from a bank or licensed BDC that sold you the currency.
- A sale agreement, if the cash came from selling an asset abroad.
Ask before you deposit, not after. Some banks note the status of a deposit at the counter, and it is easier to settle the question with papers in hand. Our guide to depositing dollar cash covers the counter process.
Worked example
Example only. Ada receives US$3,000 by wire from a client in London and deposits US$2,000 in cash that she bought from a licensed BDC, keeping the receipt. Her dollar balance is US$5,000. A bank applying the common practice above would treat US$3,000 as transferable at once. With the BDC receipt, it may agree to treat the other US$2,000 as transferable too; without it, Ada could still withdraw that US$2,000 in cash or convert it to naira, but might not be able to send it abroad. Her total transferable balance is therefore US$3,000 or US$5,000, depending on the papers.
Mixed balances
If an account holds both kinds of funds, the bank tracks them separately. A transfer abroad may be allowed only up to the transferable part. If you plan to send money overseas regularly, for fees or a mortgage, consider keeping wired-in funds in their own account so the record stays clean.
What to check first
- Ask the bank for its written policy on cash-funded foreign currency.
- Keep every declaration and receipt for cash you deposit.
- Before a large transfer, confirm how much of your balance the bank treats as transferable.
For the wider framework, see domiciliary account rules in 2026 and the 2026 FX Manual for personal accounts.
Where Pryme fits
Money paid into a Pryme USD, GBP or EUR account arrives by transfer to local account details, so its origin is on record. It stays in that currency until you use Swap.
Questions people ask
What is non-transferable dollar in a domiciliary account?
Foreign currency, usually cash deposited over the counter, that the bank will not send abroad until its source is shown.
Can I transfer cash deposited dollars abroad?
Some banks allow it once you prove the source, for example with a Customs declaration or BDC receipt. Ask your bank.
Why did my bank refuse to transfer my dollars?
Often because the balance was funded with cash and the bank treats it as non-transferable under its anti-money-laundering policy.
Are wired dollars always transferable?
Usually, because the sending bank documents the origin, but the bank still applies its own checks on purpose and beneficiary.
