Why currency risk management matters
Currency risk management is the process of identifying, measuring and managing the impact of exchange‑rate movements on your cash‑flows and margins. For importers and exporters, FX risk appears in three places:
- Transactional risk — the GBP cost of a foreign‑currency invoice changes until settlement.
- Translational risk — the GBP value of foreign‑currency assets/liabilities moves when you report.
- Economic risk — long‑term competitiveness shifts with structural currency trends.
This guide focuses on transactional risk for UK importers because it hits cash‑flow and gross margin directly.
Step 1 — Map exposures clearly
Start by mapping where FX risk lives in your order‑to‑cash and procure‑to‑pay cycles. Capture each exposure on one line using a simple sheet:
- Currency pair & direction: e.g., GBP→USD payables; EUR→GBP receivables.
- Amount & timing: invoice date, ship date, payment terms, settlement month.
- Certainty: committed purchase order vs forecast demand.
- Business context: PCB batch run (electronics), harvest window (food), LME‑linked shipment (metals).
Group exposures by month/quarter. This reveals when cover is needed and how sensitive your margin is to GBP/USD or EUR/GBP moves. For example:
- Electronics Market: USD exposure bunches around PCB production windows and component shipments.
- Food Market: Seasonality and harvests create spikes in EUR/USD payables.
- Metals Market: USD/CNY exposure ties to LME‑linked contracts and shipment schedules.
Worked example: a UK electronics buyer has USD 1,500,000 payable in 90 days. At a budget rate of 1.2600 (GBP/USD), the planned GBP cost is roughly USD 1,500,000 ÷ 1.2600 ≈ £1,190,476. If the market weakens to 1.2300 by settlement, the cost becomes USD 1,500,000 ÷ 1.2300 ≈ £1,219,512—around £29,000 more. The mapping exercise helps you decide what portion to secure in advance.
Step 2 — Set a policy and a budget rate
A simple written policy reduces decision friction and improves auditability. Keep it short and practical:
- Objective: protect gross margin and cash‑flow predictability.
- Hedge‑ratio bands: e.g., secure 60–80% of committed purchases; maintain a lower coverage range for forecasts.
- Budget rate: the internal planning rate (e.g., 1.2600 GBP/USD) that triggers action if breached.
- Permitted instruments: forwards, market orders (limit/stop‑loss) and natural hedging; consider options only when appropriate.
- Approval thresholds & KPIs: who signs off larger/longer trades; measure variance‑to‑budget, realised rate vs market, and hedge coverage.
Tip: many teams use layered hedging—spreading cover dates across 3–6 months—to reduce timing risk and smooth cash‑flows.
Step 3 — Choose the right mix of tools
Blend instruments so you gain certainty where needed and flexibility where possible. Each tool has a clear role, pros and considerations:
Forwards
What they do: Fix (secure) today’s rate for a future date to support cash‑flow predictability.
When they help: committed POs, thin margins, or regulatory/board requirements for predictability.
Considerations: forwards are binding derivatives and may require collateral if rates move against you. Plan headroom for margin calls and monitor utilisation.
Market orders (limit & stop‑loss)
What they do: Limit orders target a better rate; stop‑loss caps downside by executing at your chosen floor. Useful when you can’t monitor markets constantly.
When they help: to capture opportunistic levels around your budget rate, or to prevent adverse moves during illiquid hours.
Considerations: choose levels based on policy, not guesswork; review after macro events.
Natural hedging
What it is: offsetting USD inflows against USD outflows (or EUR vs EUR), or aligning supplier/customer currencies. This reduces reliance on derivatives.
When it helps: distributors with foreign‑currency sales, exporters with foreign‑currency costs, or businesses with multi‑currency cash‑flows.
Considerations: requires operational coordination (pricing, procurement, AR/AP) and may affect customer terms.
Options (use selectively)
What they do: options can protect against adverse moves while allowing upside, but premiums add cost.
When they help: higher‑margin or high‑uncertainty scenarios; seasonal or tender‑based exposures.
Considerations: options may be less suitable for everyday SME purchases due to premium costs; evaluate case‑by‑case.
Step 4 — Execute cleanly and monitor
Execution quality matters as much as the tool choice. A simple, repeatable workflow limits errors and improves speed:
- Pre‑trade pack: confirm PO amounts/dates, budget rate, hedge ratio, sign‑off authority.
- Order placement: set market orders around policy levels; avoid bunching execution on a single day.
- Settlement & proof: use named multi‑currency accounts to receive/pay in the same currency where appropriate; request payment proof (e.g., MT103) when needed.
- Margin headroom: track forward utilisation and maintain balances for potential margin calls.
- Post‑trade record: log date, rate, rationale and approver for audit and performance review.
Controls to consider
- Two‑person rule for larger trades.
- Exception log when deviating from policy (e.g., urgent shipment).
- Daily position view of outstanding exposures, filled orders and upcoming settlements.
Step 5 — Review monthly and refine
Hold a short monthly review so you can adapt to market moves and business changes:
- Coverage vs plan: secure the committed portion on time; adjust forecasts and ratios.
- Variance‑to‑budget: compare realised vs budget rates; analyse any slippage to process or timing.
- Next‑month triggers: central‑bank decisions (BoE, ECB, Fed) and CPI releases that typically move GBP/USD or EUR/GBP.
- Supplier terms: reconsider whether to request GBP, USD or EUR invoicing—and why.
Example rhythm: quarterly policy review; monthly coverage/variance review; weekly order‑level check‑in around macro events.
Checklist
- List all FX exposures by currency and month (committed vs forecast).
- Agree a budget rate and hedge‑ratio bands (e.g., 60–80% of committed).
- Choose instruments: layered forwards, market orders; natural hedging where possible.
- Execute against policy; document trades and monitor margin headroom.
- Review outcomes monthly; adjust levels and instruments accordingly.
