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
When the naira weakens against the Canadian dollar, each naira buys fewer Canadian dollars, so the CAD value of naira savings falls even though the naira balance has not changed. Interest earned in naira offsets some or all of that, depending on which is larger. If you will spend the money in Nigeria, what matters more is naira prices at home; if you will bring it to Canada, the exchange rate is what counts.
What devaluation does to a balance
Your naira savings are measured in naira. Your life in Canada is measured in Canadian dollars. The link between them is the exchange rate. If it takes more naira to buy one Canadian dollar than it did last year, the same naira balance converts into fewer Canadian dollars. Nothing has been taken from your account; its value in the currency you live in has dropped.
The Bank of Canada does not publish a naira rate; its daily table covers 24 other currencies. To value naira savings in Canadian dollars you use a naira rate against the US dollar or the Canadian dollar from another published source and keep to it. Nigeria's official rate is set in the Nigerian Foreign Exchange Market; the Nigeria library explains how in its NFEM guide.
Large moves do happen. On 15 June 2023, after the CBN announced the unification of exchange rate windows, AllAfrica reported the naira closing at ₦702.19 to the US dollar at the then I&E window, having opened at ₦658.50. That is history, not a forecast, but it shows how quickly the value of a naira balance can shift.
Worked example (illustrative figures only)
Say you hold ₦5,000,000 in a Nigerian savings account.
| Start of year | End of year, no interest | End of year, with interest | |
|---|---|---|---|
| Naira balance | ₦5,000,000 | ₦5,000,000 | ₦5,900,000 (example 18% interest) |
| Example rate | ₦1,100 per CAD 1 | ₦1,375 per CAD 1 | ₦1,375 per CAD 1 |
| Value in CAD | CAD 4,545.45 | CAD 3,636.36 | CAD 4,290.91 |
In this example the naira needed per Canadian dollar rises by 25% (from 1,100 to 1,375). Without interest, the savings lose 20% of their Canadian dollar value, CAD 909.09. With 18% interest, they still end the year worth about CAD 255 less than they started, in Canadian dollar terms, because the currency fall is bigger than the interest.
The arithmetic behind it
For a CAD-based saver, the change in value over a period is roughly (1 + naira interest rate) ÷ (1 + rise in naira per CAD) − 1. In the example, 1.18 ÷ 1.25 − 1 = −5.6%. If the naira interest rate is higher than the rise in naira per Canadian dollar, you come out ahead in CAD; if it is lower, you fall behind. Neither figure is known in advance, which is the risk.
When it matters and when it matters less
- Money you will spend in Nigeria (family support, school fees, building costs): the exchange rate matters less than naira prices. If prices at home rise faster than your interest, you lose purchasing power, whatever the CAD value says.
- Money you plan to bring to Canada (a down payment, an emergency fund): the CAD value is what counts, so devaluation is a direct cost.
- Money with no fixed purpose: decide which of the two it really is. Savings tend to drift into the first group without a plan.
Ways people manage the risk
- Hold in naira only what you expect to spend in naira, and keep the rest in the currency you will use it in.
- Convert in stages rather than all at once, so no single rate decides the outcome.
- Compare the interest you are earning with the change in the exchange rate each year, not just the interest rate.
- Keep emergency money in the currency of the emergency: Canadian dollars for Canadian costs.
- Write down your rate and date each time you convert, for your own tracking and for the CRA.
- Review the plan once a year, when you file your Canadian return, and move what you no longer need in naira.
Deposit insurance does not help here. Naira deposits at licensed Nigerian institutions are insured by the NDIC up to the applicable limit, which protects you if the institution fails, not against changes in the exchange rate.
The Canadian tax side
Interest on naira savings is income for a Canadian tax resident, reported as world income in Canadian dollars. CRA Folio S5-F4-C1 says to convert at the Bank of Canada rate for the day the amount arises, and where there is none (as for the naira), to use another widely available, verifiable, independent rate consistently. Whether a currency loss can be claimed depends on what you hold and how; see our article on naira falls and capital losses and how a falling naira affects a CAD-based investor. This is information, not tax advice.
Where Pryme fits
A Pryme account holds naira alongside US dollar, sterling and euro balances, and you choose when to Swap, with the rate shown first and the fee on its own line. Naira you mean to spend at home can sit in Savings Boxes (Flexible, Fixed, Investment or Interest-free), with rates shown in the app. Naira is held by a licensed Nigerian microfinance bank, regulated by the CBN.
Questions people ask
Does naira devaluation reduce my savings?
Your naira balance stays the same, but it converts into fewer Canadian dollars. If you will spend the money in Nigeria, naira prices matter more than the exchange rate.
Can naira interest make up for devaluation?
Only if the interest rate is higher than the rise in naira per Canadian dollar over the same period. Neither is known in advance.
Should I convert my naira savings to Canadian dollars?
It depends on where you will spend the money. Many people keep in naira only what they expect to spend in Nigeria and convert the rest in stages.
Does NDIC insurance protect against a falling naira?
No. NDIC insurance covers deposits up to the applicable limit if an insured institution fails. It does not protect against exchange rate changes.
