Why hedge currency risk? Theories, myths and the reality of FX risk

Ten reasons businesses hedge currency risk, and ten myths that stop them. One clearer way forward.

Executive Summary

Currency hedging means using financial instruments, including forward contracts and options, to lock in an exchange rate and protect a business from the cost of future currency movements. Businesses hedge currency risk to ensure that revenues, costs and margins stay predictable, regardless of what FX markets do next.

Yet despite the scale of the risk, most SMEs do not hedge. Pricing can be right. Demand can be strong. Execution can be solid.

And still, value leaks out through currency movements no one planned for.

Yet many firms continue to rely on assumptions that feel sensible but fail under pressure.

That FX will “average out”.

That natural hedging is enough.

That hedging is about beating the market, not protecting the business.

The reality is much harsher than this.

The cost of not hedging currency risk is well documented: in 2024, 76% of UK and US corporates experienced losses due to unhedged FX risk, even when volatility persisted across global markets.¹

That’s material risk.

In this report, Pritesh Ruparel, CEO of Alt21, the hedging platform built for businesses, challenges the comfortable myths that keep FX risk under-managed.

We highlight ten of the most common assumptions we come across when speaking to companies about hedging. Then, separate what sounds right from what actually happens to margins, cash flow, forecasts and confidence when currencies move.

From natural hedging and governance to pricing and growth, we find that inaction is still a decision, just not a controlled one.

Hedging is not about prediction. It is about protection.

That is not to say that hedging is the right approach for every business. The appropriate level of FX protection will depend on the size, predictability and frequency of your currency exposure and overall risk appetite.

But if FX matters to your revenues, your costs or your credibility, the myths are worth confronting because the cost of not doing so is rarely obvious at first.

Until it is.

1. Earnings Stability

Hedging stabilises earnings so performance reflects decisions, not FX rates.

Theory

Hedging stabilises earnings by removing currency volatility from reported results.

When revenues or costs are known in advance, hedging locks in exchange rates so financial performance reflects operational execution, not market swings.

In theory, this creates cleaner earnings, clearer reporting and fewer surprises at quarter end. It allows management and stakeholders to assess performance on what the business controls, rather than on movements in FX markets that sit entirely outside it.

Earnings volatility caused by FX will “wash out” over time. Good periods will offset bad ones and the business can ride it out, right?

This myth assumes currency markets behave symmetrically and align neatly with reporting cycles. It also assumes stakeholders are patient enough to ignore short-term distortion.

In practice, this belief downplays how earnings volatility affects confidence, valuation and decision-making long before any theoretical averaging occurs.

Reality

FX volatility rarely cancels out on your timetable.

It hits earnings unevenly and often at the worst possible moment. One adverse move can overwhelm months of solid trading. Without hedging, reported results become a reflection of market noise rather than business performance.

Hedging does not inflate earnings. It protects them and keeps reported results anchored to reality.

2. Protecting Margins

Hedging protects agreed margins and stops FX from renegotiating deals after the fact.

Theory

Hedging protects margins that have already been negotiated and agreed. Once pricing is set with customers or suppliers, FX movements should not be allowed to rewrite the economics of the deal.

Hedging fixes the exchange rate assumption built into those margins, ensuring the commercial outcome matches the original intent.

In theory, this keeps profitability aligned with pricing discipline, not at the mercy of currency swings after contracts are signed.

Hedging is about trying to secure a better rate than the market.

If the rate improves, great. If it moves against you, that is just part of doing business.

This thinking quietly reframes hedging as speculation. It also implies that margin erosion is acceptable if it is caused by FX rather than poor pricing or cost control. Few businesses would tolerate that logic elsewhere.

Reality

Margins are fragile. FX volatility can erode them faster than any operational inefficiency.

Without hedging, a profitable deal can become marginal or loss-making purely due to currency movement.

Hedging does not aim to improve margins. It defends them. It ensures that the profit you priced, sold and planned for is the profit you keep, regardless of what markets do next.

3. Cash flow certainty

Hedging makes cash flow predictable and this is what keeps businesses solvent and confident.

Theory

Hedging creates certainty over future cash flows by fixing the FX rate applied to known exposures.

When amounts and timings are predictable, hedging allows treasury teams to plan liquidity with confidence.

In theory, this supports better working capital management, clearer funding decisions and fewer last-minute adjustments. Cash becomes something that can be planned around, rather than constantly re-estimated as exchange rates move.

Cash flow matters less than profit. Timing issues can be managed later. If the business is profitable, liquidity will take care of itself.

This myth underestimates how quickly FX movements can disrupt cash positions, even when margins look healthy on paper. It also assumes access to funding is always available, cheap and immediate, which is rarely true in practice.

Reality

Cash flow breaks businesses long before the P&L does.

FX volatility can accelerate or delay cash movements in ways that strain liquidity at exactly the wrong moment. Without hedging, forecasts drift and buffers shrink.

Hedging locks in both the value and timing of cash flows. It turns uncertainty into something manageable, giving finance teams control when it matters most.

Not all hedging products work the same way. Forward contracts lock in a rate but can tie up cash and create margin call obligations if markets move significantly. Products like options can offer more flexibility, allowing businesses to manage exposure in a way that better fits their liquidity position and commercial objectives.

4. Natural Hedging

Natural hedging can help but it rarely goes far enough. Financial hedging is what makes protection reliable.

Theory

Natural hedging reduces FX exposure by aligning foreign-currency revenues with costs in the same currency.

When inflows and outflows broadly match, the net exposure appears smaller. In theory, this lowers reliance on financial hedging and feels operationally smart.

It embeds FX risk management into the business model itself, rather than treating it as a separate treasury activity, which is why it is often viewed as a neat, low-cost solution.

If revenues and costs are in the same currency, FX risk is effectively neutralised. There is nothing left to hedge.

But do volumes move in sync? Do margins stay constant? Do all cash flows occur at the same time?

It also assumes the business structure does not change. In reality, these conditions rarely hold for long, especially in growing or seasonal businesses.

Reality

Natural hedges are often imperfect and unstable. Timing gaps, volume mismatches and margin changes quickly reopen exposure.

What looks balanced one quarter can unravel the next. Natural hedging can reduce risk in certain circumstances but it does not eliminate it.

Financial hedging locks in what operational alignment can only approximate. One absorbs some shock. The other provides certainty.

5. Management Focus

Hedging protects management attention. Focus is a strategic asset, not a soft benefit.

Theory

Hedging removes FX from everyday decision-making. By fixing exchange rates in advance, management can focus on pricing, growth and execution without constantly second-guessing currency impacts.

This simplifies conversations across finance, sales and operations. Performance discussions stay grounded in what the business can control, rather than being derailed by movements in markets that no one inside the organisation influences.

FX can be managed alongside everything else. It is just another variable to monitor.

This assumes management time is elastic and distraction-free. It also assumes FX risk stays neatly contained within treasury.

In practice, unhedged FX seeps into pricing debates, forecast revisions and internal explanations. It becomes a background anxiety that consumes attention without ever being fully resolved.

Reality

FX risk can become a mental burden. When left unmanaged, it forces management to react instead of plan.

Decisions become tentative. Accountability blurs. Hedging draws a clear line around currency exposure and closes the loop. It frees leadership to concentrate on strategy and execution, not on explaining why results moved for reasons unrelated to performance.

6. Shareholder and investor confidence

Hedging strengthens confidence by making results easier for investors to trust, understand and value.

Theory

Hedging signals disciplined financial management. By actively managing FX exposure, companies show investors that risks are identified, measured and controlled.

This builds confidence in earnings quality and governance. Results are easier to understand and performance reflects strategy rather than market noise. For investors, predictability often matters more than short-term upside.

Investors look through FX and they only care about underlying performance.

This assumes shareholders are comfortable separating operational results from currency impacts every reporting period. It also assumes repeated FX-driven surprises do not affect trust. In reality, unexplained volatility raises questions. It makes results harder to interpret and weakens confidence in management’s grip on risk.

Reality

Investors notice what management ignores. Repeated FX-driven earnings surprises make results harder to interpret and raise questions about whether risk is truly under control.

Unexplained volatility does not just affect one reporting period, it creates a pattern that erodes confidence over time. Hedging demonstrates that management has identified the exposure, made a deliberate decision, and put a structure around it. That signal matters to investors and boards, particularly when earnings need to be trusted, not explained away.

7. Risk governance and compliance

Hedging turns FX risk into a measurable, governed part of the business, not an uncontrolled.

Theory

Hedging supports formal risk management frameworks and observes corporate governance standards. By actively identifying, measuring and managing FX exposure, companies can report on risk in a structured way.

In theory, this satisfies boards, auditors and regulators, showing that the organisation treats currency risk as a managed variable rather than an uncontrolled external factor.

FX risk isn’t a governance issue. It’s just a market movement, not a compliance matter.

This implies that boards and stakeholders don’t notice or care about unhedged exposures. Also, internal policies and risk frameworks would need to be flexible enough to absorb surprises.

But, if FX remains unmanaged, it can be viewed as a lapse in governance, exposing the company to scrutiny, reputational damage or internal misalignment.

Reality

Boards and regulators expect transparency and measurable controls. Hedging makes FX risk quantifiable, auditable and reportable.

It also transforms what could be a silent policy failure into a documented, managed process. Beyond compliance, it embeds discipline into the organisation, ensuring decisions and forecasts reflect actual exposure rather than guesswork or assumption.

8. Efficiency rather than cost

Choose FX partners for efficiency, service and reliability, not just for lower cost. Relationships, not rates, deliver sustainable value.

Theory

Non-bank FX providers are often chosen for their efficiency, service and flexibility. They simplify processes, speed up execution and give treasury teams more control and visibility.

This should allow companies to manage FX exposure with less internal friction, freeing time for strategic decision-making rather than chasing rates or reconciling manual transactions.

The real value lies in smooth operations and reliability, not just price.

Non-banks are better because they are cheaper. Lower spreads and fees are the primary attraction.

This myth assumes that FX is a commodity where cost alone drives long-term value. However, chasing the lowest price without considering service, reliability or relationship often results in frustration, delays and missed opportunities.

Cost savings alone rarely create a sustainable partnership or risk reduction.

Reality

Efficiency and trust drive value in FX relationships, not marginally lower rates.

An operationally efficient and clear provider saves you hours.  And when it also seamlessly integrates into your treasury process, it will likely contribute more to profitability than the occasional basis point saved.

Building a positive, long-term relationship with a provider ensures consistent execution and proactive support, which protects margins far more reliably than simply paying less.

9. Competitive pricing stability

Hedging safeguards pricing stability, preserving both margin and customer trust in volatile markets.

Theory

Hedging allows companies to offer consistent prices to customers, regardless of currency fluctuations.

By fixing FX rates in advance, businesses can maintain predictable margins and avoid passing sudden costs onto clients.

In theory, this strengthens trust, supports long-term contracts and positions the company as reliable in volatile markets. Stable pricing also simplifies internal planning, as finance and sales can forecast outcomes without constantly adjusting for market swings.

Are customers often accepting of frequent price changes? Is renegotiation frictionless? Do competitors always behave in a similar way, so there’s no risk of losing deals or damaging reputation?

No. In reality, repeated repricing erodes trust, frustrates customers and makes contracts harder to close. Volatility can turn a competitive advantage into a credibility risk if pricing feels unpredictable.

Reality

Hedging absorbs FX shocks internally, allowing pricing to remain consistent for customers. It protects both margin and reputation, turning currency risk into an operational detail rather than a sales negotiation point.

Companies that hedge can honour commitments without scrambling, giving them an edge over competitors forced to adjust rates constantly.

10. Strategic flexibility

Hedging gives businesses the freedom to grow confidently, turning FX risk from a constraint into a controlled factor.

Theory

Hedging provides companies with the confidence to expand into new markets or pursue growth initiatives without worrying about FX swings.

By locking in rates in advance, businesses can make investment, pricing and operational decisions with clarity.

This allows management to plan long-term initiatives and explore new opportunities, as well as negotiate contracts abroad, without being constrained by currency uncertainty.

This assumes FX risk is only material at scale. It also implies waiting until problems arise before taking action.

However, exposure is often largest when visibility is lowest, such as in early-stage projects or investing in emerging markets. These can often result in timing mismatches and unexpected cash flows that can magnify the impact of FX.

Reality

Early and proactive hedging creates a stable foundation for growth.

It allows companies to act decisively and invest confidently, rather than being reactive to market moves.

Hedging doesn’t remove risk entirely but it transforms FX uncertainty into a manageable variable, giving leadership the flexibility to pursue strategy rather than constantly adapting to currency volatility.

Why hedge currency risk: from theory to action

Why hedge currency risk? Because FX is not a theory problem. It’s a reality problem.

Throughout this report, there’s one theme that keeps resurfacing:

So why hedge currency risk? Because most companies don’t fail to hedge because they do not understand FX. They fail because they rely on assumptions that feel comfortable, familiar and widely repeated.

They assume that FX will balance out, natural hedging is enough, hedging is optional or it’s something to visit later.

But in reality, if FX impacts your revenues, costs or cash flow, then you’re exposed. For those businesses with material FX exposure, choosing not to hedge is not a ‘neutral’ position but simply an unmanaged one.

The businesses that hedge well, whether using forward contracts to lock in rates, options to preserve upside, or a structured hedging programme, are not trying to outsmart the market. Their goal is simpler and far more practical: to remove FX from the conversation altogether once commercial decisions are made. They protect margins after they are agreed, stabilise earnings after reporting periods and give management the freedom to focus on execution rather than explanation.

The clearer way forward is action, not theory.

And that starts with defining exposure properly and putting structure around FX risk instead of reacting to it afterwards.

Currencies move whether you prepare for it or not. The only real choice is whether those movements are absorbed deliberately or allowed to work against the business when it matters most.
