A 10% rand move between order and invoice can erase your entire margin. Here’s exactly how exchange rates hit your business and what to do about it in 2026.

Most African business owners know that exchange rates matter. Fewer understand precisely where currency movements enter their business model, which makes the risk harder to manage and the damage harder to anticipate. The point is not that every business needs a treasury function. Currency exposure is already embedded in your pricing, supplier contracts, inventory, and cash flow, whether you are actively managing it or not.

Where currency movements actually enter your business

Exchange rate changes affect your business through five distinct channels, and most businesses face at least three at once.

Input costs: Any business sourcing raw materials, components, equipment, or finished goods priced in a foreign currency is exposed the moment that currency moves. A South African importer who places an order when the rand is at a certain level and receives the invoice three weeks later, after a 10% depreciation, has seen their entire margin compressed without a single operational decision changing.

Harry Scherzer, CEO of Future Forex, describes this precisely: “A contract is only as stable as the currency used to pay it.” For Nigerian businesses importing goods priced in dollars, the same dynamic applied with acute force during 2023 and 2024, when the naira lost over 51% of its value in 2023 and a further 129% in 2024. Input cost inflation driven by FX movements is indistinguishable from domestic inflation to the consumer, but its cause and management differ entirely.

Pricing and competitive position: When your local currency weakens, your dollar-priced goods become more expensive in local currency terms, forcing a choice between absorbing the margin hit and raising prices, risking volume loss. When your currency strengthens, imported competitors gain a pricing advantage. Businesses must constantly monitor exchange rate trends to maintain competitive prices; those that don't are consistently surprised by shifts their competitors anticipated and planned for.

Cash flow timing: The gap between invoice date and payment settlement date is where most FX losses occur in practice. Currency movements between when a deal is agreed and when payment arrives can turn a profitable transaction into a loss-making one. For businesses with 30-, 60-, or 90-day payment terms for cross-border transactions, this exposure is not hypothetical. It is embedded in every receivable and payable on the books.

Foreign-currency debt: Any business that has borrowed in a foreign currency- whether a dollar-denominated bank loan, a supplier credit facility, or an international bond - carries a liability that grows in local currency terms when the local currency weakens. A currency weakening of 20% effectively increases the local-currency cost of a foreign-currency loan by 20%, independent of any change in the loan’s interest rate or repayment terms. Ghanaian businesses with dollar debt felt this acutely in 2022, when the cedi fell more than 55% against the US dollar between January and October, among the steepest falls of any currency in the world that year.

Remittance and payroll: For businesses with employees, contractors, or service providers in different currency zones, exchange rate movements directly affect payroll costs in ways that compound over time. A business paying freelancers in dollars from a naira revenue base has a cost structure that moves with the exchange rate regardless of its own pricing decisions.

The emerging pattern: Volatility is the new normal

Africa’s cross-border payment market is projected to reach $1 trillion by 2035, up from $329 billion in 2025, according to a 2025 report by Oui Capital, meaning more African businesses will have more FX exposure than at any previous point.

The US-Iran conflict, which disrupted oil supplies and pushed energy prices sharply higher in the first half of 2026, also intensified currency pressure across oil-importing African markets. Among the currencies tracked in H1 2026, Tanzania’s shilling recorded the sharpest decline at 5.62%, followed by Ghana’s cedi at 5.46% and Botswana’s pula at 5.16%, according to BusinessDay’s H1 report. Individual currencies move in different directions, but volatility does not.

The businesses managing this best in 2026 are not trying to predict currency movements. The goal is not to forecast the market perfectly. The goal is to manage exposure in a disciplined way so that currency movements do not disrupt the commercial side of the business. That distinction matters. Currency prediction is speculation. Currency risk management is operations.

Three practical responses that work in African markets

Forward contracts for predictable exposures: If you know you will pay a supplier in dollars in 60 days, a forward contract locks in today’s rate for that future transaction. Forward contracts fix your margins even if the currency moves adversely between now and the payment date. Most commercial banks and specialist FX providers across Nigeria, Kenya, and South Africa offer them.

Currency adjustment clauses in contracts: Long-term supplier or client contracts without currency adjustment mechanisms transfer all exchange rate risk to whichever party holds the local currency. Negotiating adjustment clauses that share FX risk between buyer and seller is a structural fix that does not require a financial instrument.

Invoice currency selection: Where commercial relationships allow, invoicing in your functional currency rather than your counterpart’s transfers the conversion cost and risk to them. This is not always negotiable, but in markets where buyers have options, sellers who offer local-currency pricing often win business that dollar-priced competitors lose to currency friction.

FAQ

Does exchange rate risk affect businesses that don’t import or export? Yes. Any business using imported inputs, paying for technology priced in dollars, employing contractors across currency zones, or holding foreign-currency debt is exposed. Even purely domestic businesses face FX exposure through their supply chains, since most raw materials, fuel, and technology are internationally priced.

What is a forward contract and is it available to SMEs in Africa? A forward contract locks in an exchange rate for a future transaction, eliminating the risk of adverse currency movement between agreement and settlement. Most commercial banks in Nigeria, Kenya, South Africa, and Ghana offer forward contracts to business customers, and specialist FX providers often offer more competitive rates than banks for standard currency pairs.

How do you know if your contract has adequate currency protection? Review whether your contracts specify the currency of payment, reference exchange rate adjustments, and define which party bears the conversion cost. If the answers are vague or absent, the contract is allocating currency risk by default rather than by decision. The party receiving payment in a currency that is not its functional currency typically absorbs the risk.

What is the most common FX mistake African businesses make? Waiting until an invoice arrives before addressing currency exposure. By then, the rate is set, and the loss is already embedded in the transaction. Businesses that address FX exposure at the contract stage through forward contracts, adjustment clauses, or invoice currency selection consistently protect margins more effectively than those managing it reactively at payment.
