Currency volatility and the margin problem that hedging can't fix

Hedging protects you from the big swings. It's the thousands of small conversions in between that quietly eat your margin.

At what point does volatility stop being the exception and start becoming the norm?

In April 2025, sweeping US tariff announcements triggered a US$6.6 trillion global market loss in 48 hours. Between January and September, EUR/USD moved from 1.02 to 1.18, a 14% swing in a single currency pair. And 2026 has brought no reprieve, with trade wars intensifying and geopolitical conflict feeding fresh currency volatility on a near-weekly basis. That's on top of tariff shocks, a weakening dollar, and monetary policy pulling in opposite directions on each side of the Atlantic.

For a business with €10 million in annual European revenue, that movement represents a potential margin shift of €1.4 million, enough to wipe out a quarter's profit or fund an entire market expansion. The old approach to FX, hedge selectively and hope for the best, was designed for calmer times. Protecting margin in this one demands something more deliberate.

FX volatility has become permanent

For most of the past two decades, currency swings followed a recognisable pattern. Central banks signalled rate changes months in advance, trade policy shifted gradually, and finance teams could plan around relatively stable corridors. That world is gone.

The dollar index fell below 100 for the first time since 2022, and its traditional safe-haven status broke down as capital moved away from US assets rather than into them. Each new tariff announcement and escalation in the Middle East repriced currency markets within days, sometimes hours.

The corporate response has been defensive. According to a survey of 750 senior finance decision-makers, 88% of mid-sized North American and European corporates now hedge their currency exposure, up from 81% a year earlier, and hedging costs have increased by a mean of 67%.

Yet 62% of those same respondents still report negative impact from currency volatility. UK corporates reported average annual losses of £6.71 million from unhedged exposure. For US firms, US$9.85 million. If nearly everyone is hedging and losses remain this high, the problem runs deeper than hedge ratios.

‘Set and forget’ FX management erodes your margin

Most mid-market businesses hedge 40–50% of their forecastable exposure, leaving at least half their currency risk unprotected. The less visible problem is the operational leakage happening in every transaction, every day, between hedged positions.

Consider how money moves through a multi-entity business. Your European subsidiary collects revenue in euros. Those euros get converted to your home currency at settlement, typically at a rate 3–5% above mid-market. When you then need to pay a supplier in euros, the money converts again. Two conversions, two markups, on the same underlying currency. This double conversion alone can represent 3–7% of total international revenue for businesses without multi-currency infrastructure.

Then there's visibility. Most finance teams get a clear picture of FX exposure once a month, at close. EUR/USD moved 4% in a single week in April 2025. By the time you're reconciling last month's transactions, the currency has already moved on.

The three-step framework to reduce FX leakage

Hedging has its place, but it addresses only one dimension of FX risk. The framework below tackles the operational mechanics that drain margin between hedged positions.

Hold: Stop converting currency you're going to need again

The most direct way to eliminate FX leakage is to avoid unnecessary conversions altogether. A multi-currency account lets your business receive, hold, and send funds in the currencies you actually use. When your European customers pay in EUR, those funds stay in EUR. When your German supplier invoice arrives, you pay from your EUR balance. The FX conversion never happens, so the markup never applies.

Take a business receiving €500,000 quarterly from European clients and paying €300,000 back to European suppliers. Converting that matched €300,000 to your home currency and back again costs roughly €18,000–€30,000 per quarter in bank markups alone. Hold euros and pay in euros, and that cost disappears. Airwallex Global Accounts let you hold funds in 20+ currencies with local bank details in 70+ countries, collecting and paying like a local without forced conversions at either end.

Convert: When you do convert, do it transparently and on your terms

You won't always have inflows and outflows in the same currency pairs. So when you do need to convert funds, the FX rate you get and the control you have over timing determine how much margin you get to keep.

Traditional banks bundle their FX margin into the exchange rate without disclosing it separately. You see one number, with no way to know whether you're paying 1%, 3%, or more above mid-market. On £1 million in annual FX conversions, the difference between a 3% bank markup and a transparent 0.5% rate is £25,000 in recovered margin.

With Airwallex, you convert at rates typically 0.5–1% above the mid-market rate, with the markup disclosed upfront. You see live rates for 90+ currency pairs and choose when to convert. For larger or recurring payments, you can schedule conversions at today’s FX rates or create an order to execute a conversion at a future target rate. These solutions allow you to lock in favourable rates ahead of known obligations. That visibility over rate, timing, and outcome turns FX from an unpredictable cost into something you can forecast and manage.

Control: See your exposure in real time and enforce discipline across entities

In a multi-entity business, FX exposure accumulates across revenue streams, supplier payments, corporate card spend, and intercompany transfers. Without a consolidated view, finance teams can't quantify their total position until month-end at the earliest.

Airwallex gives you a single dashboard across all entities, currencies, and transaction types. You see your global FX exposure as it develops, not three weeks later in a reconciliation spreadsheet. When EUR weakens mid-month, you can act immediately, whether that means accelerating a conversion, adjusting a payment schedule, or flagging the exposure to your treasury team.

On the spend side, multi-currency corporate cards let employees transact in local currencies without foreign transaction fees or forced conversions, with spending limits and permissions set per card, entity, and currency. When FX movements are persistent and repricing happens faster than your reporting cycle, control means treating currency as an operational discipline, not a line item you absorb after the fact.

Global is the new default. Your finance stack needs to reflect that.

If you operate across borders, FX exposure runs through your revenue, your costs, and your working capital whether you hedge or not. Most businesses losing margin have hedging programmes in place. What they lack is infrastructure underneath, the kind that holds currencies where they're earned, converts at rates you can actually see, and gives you a live read on your global position instead of a month-old snapshot.

Margin protection in 2026 looks like good plumbing – it’s so good you never notice it. The finance teams pulling ahead have stopped trying to predict where EUR/USD goes next. They've built systems that make the answer matter less.
