Surviving a Falling Naira: Managing Currency Risk in Your Business

For a business operating in a volatile currency, the exchange rate is not a background news item. It is a silent partner in every decision, and when it moves against you it can erase a year of hard-won margin in a single quarter. If you import anything, pay for software in dollars, or borrow in a foreign currency, this is your risk to manage, not the central bank’s.

The numbers are not abstract. In 2024 alone the Nigerian naira depreciated by roughly 129% against the dollar, closing the year near 1,479 to the dollar, while inflation hit a 28-year high of 34.8%. Businesses that had not planned for a move on that scale did not merely lose margin; some did not survive it.

Founders in stable economies get to treat currency as a constant. Founders in Nigeria, and much of the continent, do not have that luxury. The naira has lost value against the dollar repeatedly and sharply, and each move quietly rewrites the economics of every business that touches foreign currency. The good news is that currency risk is measurable and, to a large degree, manageable. It rewards founders who plan for it and punishes those who hope it away.

The real exposure is a mismatch

Currency risk is rarely about the rate itself. It is about a mismatch between the currency you earn in and the currency you spend in.

A business that earns naira and spends naira feels a weaker naira mainly through inflation. A business that earns naira but pays for stock, hosting or loans in dollars feels every depreciation directly: its costs rise while its prices, set in naira, lag behind. That gap between rising hard-currency costs and slower-moving local revenue is where margin quietly disappears.

So the first job is to measure the mismatch honestly. Split your costs into two buckets, hard currency and local, and do the same for revenue. The larger the share of costs in hard currency relative to revenue, the more exposed you are. This single ratio is the most important currency number in your business, and most founders have never written it down.

A worked example

A business sells only in naira and makes 20 percent margins. Forty percent of its costs are dollar-linked (imported inputs and software). The naira weakens 25 percent against the dollar over a year.

Those dollar costs now cost 25 percent more in naira. If they were 40 percent of a cost base that consumed 80 percent of revenue, that is a rise of roughly 8 percent of revenue in costs, with prices unchanged. A 20 percent margin becomes a 12 percent margin. The business did nothing wrong. The rate did the damage. And because the loss shows up gradually, month by month, many founders do not connect the shrinking margin to the exchange rate until the year is already lost.

Natural hedges beat financial ones

Large companies manage currency risk with forward contracts and hedging instruments. Most small businesses cannot access those easily or cheaply. The stronger tools for an SME are natural hedges, structural choices that reduce the mismatch itself.

1. Earn in the currency you spend. If your costs are partly in dollars, pursue some revenue in dollars: export customers, diaspora clients, or foreign-currency contracts. Even a modest hard-currency income stream cushions every depreciation, and it is often the single most powerful move available to an African SME.
2. Price in, or index to, the hard currency. Where the market allows, quote prices that move with the rate, or review prices frequently enough that they keep pace. A price list frozen for a year in a depreciating currency is a slow giveaway.
3. Shorten the time you hold local cash. The longer money sits in a weakening currency, the more value it loses. Collect faster, and do not stockpile local cash you will need to convert later.
4. Match the currency of your debt to your revenue. Borrowing in dollars to fund a naira-earning business is one of the most dangerous mismatches there is, and it deserves its own warning below.

The dollar-debt trap

Foreign-currency debt is where currency risk turns from a margin problem into a survival problem. When you borrow in dollars but earn in naira, a depreciation attacks you from two sides at once: the amount you owe grows in naira terms, and so does every interest payment, while the income meant to service it does not move. Businesses that looked comfortably financed at one rate have been pushed under by a single sharp move.

The rule is simple and worth holding firmly: borrow in the currency you earn in, unless you have hard-currency revenue to match the repayments. A cheaper dollar interest rate is not cheaper at all once the currency moves; it is a hidden cost that lands exactly when you can least afford it.

Repricing without losing customers

Much of the defence against a falling naira is simply keeping your prices moving with your costs, which many founders resist for fear of losing customers. The reassurance from pricing discipline applies here too: a fair increase, explained and delivered in steps, keeps most customers, and the ones who leave over it were usually the least profitable. In a depreciating currency, the real risk is not raising prices; it is not raising them, and watching a currency move turn a healthy business into a break-even one while you hold the old number out of politeness.

Review your prices on a schedule, quarterly rather than yearly, so no single increase has to be large, and so your margin never drifts far behind your costs.

Hold a buffer, and stress-test the plan

Two habits separate businesses that ride out currency shocks from those that are ambushed by them.

The first is a hard-currency buffer: a reserve held in dollars, in a domiciliary account, sufficient to cover a few months of your dollar costs. It is not idle money. It is insurance that lets you keep buying inputs when the rate spikes and local cash suddenly buys less. Build it deliberately, converting a small, steady amount when the rate is calm rather than scrambling to buy dollars in a panic when it is not, which is exactly when they are most expensive and hardest to find.

The second is to stress-test your forecast at a weaker rate. Before you commit to a growth plan, rerun it assuming the currency is 20 or 30 percent weaker. If the plan only works at today’s rate, it is not a plan, it is a bet. Knowing where it breaks lets you build in the price rises, buffers and hedges before the market forces the question.

What to do this week

• Split your costs and revenue into hard currency and local. Write down the share of each. That single ratio is your exposure.
• Identify one natural hedge you could start this quarter: a dollar-priced product, an export customer, or faster collection.
• If you carry foreign-currency debt, calculate what a 25 percent move does to your repayments, and make a plan to reduce the mismatch.
• Rerun your next few months of cash flow at a rate 25 percent weaker, and note the month things get tight.

You cannot control the exchange rate. You can control how much of your business depends on it staying still. The founders who thrive through currency volatility are simply the ones who planned for movement instead of praying against it.
