Managing Currency Risk on Long-Term International Projects

Category: Foreign Exchange & Currency Risk

International projects operate on timelines that currency markets do not respect. When you sign a contract in January to deliver a project by June, the exchange rate that looked comfortable at contract signing may look devastating by the time you actually pay your suppliers. For project contractors and cross-border service principals, this timing mismatch is one of the most significant — and most underestimated — risks to profitability.

Consider a scenario that plays out countless times each year: a UK-based project contractor wins a €500,000 contract to deliver engineering services in the Netherlands. The contract is priced in euros, which is fine — the contractor will receive euros. But the project requires subcontractors paid in British pounds, materials sourced from suppliers in Turkey who demand payment in Turkish lira, and local labour in India paid in Indian rupees. The contractor has just created a four-currency risk matrix, and they have three to six months of exposure before the project is complete and all costs are settled.

A five to ten percent adverse currency movement during that period can erase the project's entire profit margin. This is not a theoretical risk. It happens regularly, and it drives otherwise successful project contractors into loss-making positions on contracts they won fairly and executed competently.

This article provides a practical framework for managing currency risk on long-term international projects, from contract structuring to execution.

Understanding the Multi-Currency Risk Matrix

The first step in managing project-level currency risk is understanding its shape. Most operators think of FX risk in simple terms: "I earn in euros and spend in pounds." But real project economics are more complex.

For a typical international project, the currency risk matrix includes:

Revenue currency exposure. The currency in which you will be paid. This is usually fixed by the contract, though milestone payment schedules introduce timing risk.

Direct cost currency exposure. The currencies in which you pay suppliers, subcontractors, and direct project costs. These are often different from your revenue currency.

Indirect cost currency exposure. The currencies of your overhead costs — office rent, staff salaries, insurance, and professional fees — which must be covered regardless of which project they are allocated to.

Timing exposure. The gap between when you commit to costs and when you receive revenue, during which exchange rates can move significantly.

Contingency exposure. If the project overruns and costs increase, the additional costs may be in different proportions across currencies than originally planned, creating an unanticipated shift in the risk profile.

The key insight is that currency risk is not a single number — it is a matrix of exposures across currencies and time periods. Managing it effectively requires understanding each element of that matrix.

The 5-10% Shift That Erases Profit

To understand why currency risk demands active management, consider the maths of a typical international project.

Suppose a project has a contract value of $500,000 and an expected profit margin of ten percent, or $50,000. The project's costs are split across three currencies: 40% in GBP, 35% in INR, and 25% in TRY.

If the pound sterling appreciates by five percent against the dollar during the project, the GBP-denominated costs increase by five percent in dollar terms. That is a $10,000 increase (5% of $200,000). If the Turkish lira depreciates by eight percent, the TRY-denominated costs also increase in dollar terms if you are converting from dollars, adding another $10,000. If the Indian rupee moves by three percent, that is another $5,250.

In this scenario — which is well within the range of normal currency movements over a six-month period — the project's profit has been reduced by $25,250, or more than half of the original $50,000 margin. A slightly larger move, or a move in the wrong direction across more currencies, turns a profitable project into a loss.

This is why experienced project contractors treat currency risk with the same seriousness as scope creep or supplier default. It is not a peripheral concern — it is a core commercial risk.

Fixing FX Rates at Contract Signing

The most straightforward approach to managing project-level currency risk is to fix the exchange rates at the time of contract signing. This can be achieved through several mechanisms:

Forward contracts. A forward contract allows you to lock in an exchange rate today for a transaction that will occur on a specified future date. If you know you will need to pay £200,000 to a subcontractor in three months, you can buy those pounds today at a fixed rate, eliminating the risk of sterling appreciation.

Forward contracts are available from major FX providers and are accessible to businesses with annual FX volumes of $250,000 or more. The cost is typically the difference between the spot rate and the forward rate, which reflects interest rate differentials between the two currencies. For major currency pairs, this cost is usually minimal — often less than 0.5% for three-month contracts.

Pre-buying target currencies. If your multi-currency account supports it, you can simply convert the required amount into the target currency at the time of contract signing and hold it as a balance until the payment is due. This is the simplest form of hedging, though it has a cash flow implication — you are tying up capital in a foreign currency balance for the duration of the project.

Dual-currency invoicing. Some operators structure their contracts with dual-currency pricing, where the customer can choose to pay in either currency at a predetermined rate. This effectively transfers the currency risk to the customer, who may be better placed to manage it — or may accept it as part of the commercial arrangement.

FX Adjustment Clauses

For longer projects — six months or more — fixing rates at the outset may not be practical or desirable. Exchange rates can move significantly over extended periods, and a rate that seems fair today may look unreasonable in six months, potentially damaging the relationship with the client or supplier.

FX adjustment clauses provide a more flexible alternative. These clauses specify that if the exchange rate moves beyond an agreed threshold — typically three to five percent — the contract price will be adjusted proportionally. This shares the currency risk between the parties rather than placing it entirely on one side.

Key elements of an effective FX adjustment clause include:

The base rate. The exchange rate at the time of contract signing, which serves as the reference point for adjustments.

The corridor. The range within which the exchange rate can move without triggering an adjustment. A typical corridor is plus or minus three to five percent.

The adjustment mechanism. How the price adjustment is calculated and applied — whether it is a proportional adjustment to the entire contract value or only to the currency-exposed portion.

The measurement date. When the exchange rate is measured for the purpose of calculating the adjustment — at the time of invoice, at the time of payment, or at regular intervals during the project.

The cap. A maximum adjustment beyond which the clause no longer applies, protecting both parties from extreme currency movements.

FX adjustment clauses require clear drafting and mutual understanding, but they can be an effective way to manage risk without the cost or complexity of financial hedging instruments.

Project-Level FX Management vs Company-Level Hedging

There are two fundamentally different approaches to managing currency risk: project-level and company-level.

Project-level FX management involves managing the currency risk for each project individually. You identify the exposures for each project, hedge or fix the relevant rates, and track the FX outcome as part of the project's financial performance.

Company-level hedging involves managing the aggregate currency exposure across all projects. Rather than hedging each project separately, you net off exposures across projects and hedge only the residual position.

For businesses with a single large project, project-level management is the only option. But for businesses running multiple projects simultaneously, company-level hedging can be more efficient:

Natural hedges emerge when different projects have offsetting exposures.

Hedging costs are reduced because you are hedging the net position, not the gross.

Administrative burden is lower because you are managing one hedging programme rather than several.

The downside of company-level hedging is that it obscures project-level profitability. If the hedging programme produces a gain on one project's exposure and a loss on another's, the individual project results may not reflect the true commercial performance of each project.

A practical compromise is to use company-level hedging for major, recurring exposures — such as regular GBP costs for a euro-denominated business — while managing project-specific or unusual currency exposures at the project level.

This hybrid approach is particularly effective for businesses that have a baseline of recurring cross-border activity (which can be hedged efficiently at the company level) alongside project-specific exposures that vary in size, currency, and timing. The company-level hedge provides a stable foundation, while project-level management addresses the unique risks of each engagement.

The Cost of Inaction

Before moving to practical steps, it is worth reflecting on the cost of doing nothing. Many project contractors adopt a wait-and-see approach to currency risk, reasoning that exchange rates might move in their favour as easily as against them. This is technically true — but it misunderstands the nature of risk.

Currency risk is asymmetric for project contractors. A favourable movement improves your margin, which is welcome but rarely transformative. An unfavourable movement can eliminate your margin entirely, turning a profitable project into a loss. The downside is bounded only by the size of the currency movement, while the upside is bounded by your original margin.

Moreover, the impact of an adverse movement is not linear. A five percent adverse move on a ten percent margin project eliminates half your profit. A ten percent move eliminates all of it. The probability of a ten percent move over a six-month period is low for major currency pairs but not negligible, and for emerging market currencies, it is quite common.

The cost of hedging — typically 0.2% to 0.5% for major pairs over three to six months — is effectively an insurance premium against outcomes that would be commercially devastating. When framed this way, the question is not whether you can afford to hedge, but whether you can afford not to.

Practical Steps for Project Contractors

If you are running international projects with multi-currency exposure, here is a practical checklist:

At the bidding stage, model the project economics in each relevant currency. Identify the FX break-even points — the exchange rates at which the project becomes unprofitable.

At the contracting stage, decide whether to fix, share, or accept the currency risk. Document this decision in the contract, including any FX adjustment clauses.

At the execution stage, monitor exchange rates against your break-even points. If rates move beyond your comfort zone, take action — execute a forward contract, convert funds early, or renegotiate terms with the client.

At the completion stage, reconcile the actual FX outcome against the budgeted rates. This data will improve your estimation for future projects.

Over time, build a track record of FX outcomes across projects. This allows you to calibrate your risk tolerance and pricing more accurately.

Looking Forward

Currency risk management is not a luxury for large corporations. It is a commercial necessity for any business undertaking international projects of three months or longer. The tools are accessible, the costs are manageable, and the potential savings — or loss avoidance — are significant.

The operators who manage currency risk well consistently outperform those who do not, not because they are better at their core work, but because they protect their margins from a risk that is entirely manageable with the right approach. In a competitive market for international projects, that margin protection can be the difference between a sustainable business and a series of painful surprises.

For the operator just beginning to take FX risk seriously, the advice is simple: start with your next project. Model the currency exposure, identify the break-even rates, and take at least one protective action — whether that is a forward contract, a pre-buy, or an FX adjustment clause. The experience will build your confidence and your competence, and each subsequent project will be easier to protect than the last.
