Why rand volatility is the biggest hidden risk in importing
Every South African importer knows the feeling: you price a product in rands based on a USD invoice, agree a selling price with a customer, and then by the time you actually pay the supplier six weeks later, the rand has weakened by 5% and your margin has evaporated. That 5% swing on a R500,000 order is R25,000 directly out of your pocket — before you even factor in duty, VAT, or freight.
The USD/ZAR rate moves constantly and can shift 10–15% in a matter of weeks during periods of global risk-off sentiment, political uncertainty, or commodity price shocks. For an importer with thin margins, this is not a theoretical risk — it is a recurring threat to profitability.
A Forward Exchange Contract (FEC) is the most widely used tool South African importers use to remove this uncertainty. It is not speculation — it is the opposite of speculation. You are locking in a known rate so you can plan with certainty.
How a Forward Exchange Contract works
An FEC is a binding agreement between you and your Authorised Dealer bank to buy (or sell) a specific amount of foreign currency at a specific rate on a specific future date. The bank is quoting you a forward rate, which is derived from:
- The spot rate — today's USD/ZAR rate.
- The interest rate differential — South Africa's interest rates are typically higher than US rates. This differential is built into the forward rate as a premium, making the forward rate slightly worse (more rands per dollar) than the spot rate.
This means you will typically pay a few cents more per USD on a forward contract than the spot rate today. But you gain certainty — which is worth far more than the premium if the rand weakens significantly before your payment date.
Worked example — hedging a USD invoice with an FEC
Let's walk through a realistic 2026 scenario.
Situation: You are a Johannesburg importer. A Chinese supplier invoices you for USD 20,000 for a shipment of industrial equipment. The goods will ship in 60 days, and you will need to pay the supplier when the bill of lading is presented — approximately 60–75 days from today.
| Scenario | Rate used | Rand cost of USD 20,000 |
|---|---|---|
| Spot rate today | R18.50/USD | R370,000 |
| 60-day FEC rate (spot + ~1% premium) | R18.69/USD | R373,800 |
| If rand weakens to R20.00/USD (no hedge) | R20.00/USD | R400,000 |
| If rand strengthens to R17.50/USD (no hedge) | R17.50/USD | R350,000 |
Decision with the FEC: You book the 60-day FEC at R18.69/USD today. Your rand cost is locked at R373,800 regardless of what the rand does. The premium cost compared to today's spot rate is R3,800 — that is the insurance premium.
If the rand weakens to R20.00, you save R26,200 compared to paying spot on the day. If the rand strengthens to R17.50, you "miss out" on R23,800 of savings — but you also did not take a R26,200 loss risk. For most importers operating on margins of 15–30%, the certainty is worth more than the upside of a rand strengthening.
How to book an FEC with your bank
- Have an active forex facility — your bank needs to have approved you for foreign currency transactions (see our SARB payment guide). FEC booking typically requires the same setup.
- Call or contact your forex dealer — most banks have a dedicated forex dealing desk. Give them: the currency pair (e.g. USD/ZAR), the amount, and the value date (the date you want to pay).
- Get the forward rate quoted — the dealer quotes you a rate. You have a few seconds to agree (rates move). Once you say yes, the FEC is booked.
- Receive confirmation — the bank sends a written FEC confirmation. Keep this document.
- On the value date — your bank debits your rand account at the locked rate and executes the payment to your supplier.
FEC costs and what banks charge
Unlike some financial instruments, the main cost of an FEC is not a separate fee — it is embedded in the forward rate (the interest rate differential premium). However, banks may charge:
| Cost item | Typical range (2026) |
|---|---|
| Forward premium (interest rate differential) | 0.75%–1.5% on a 90-day contract (annualised ~3–6%) |
| Bank dealing margin | Built into the rate; typically 0.1%–0.3% spread |
| SWIFT/TT execution fee (on payment date) | R350–R600 flat |
| Early cancellation / close-out | Mark-to-market gain or loss; possible admin fee |
Minimum deal sizes vary by bank but are generally around USD 5,000–10,000 (approximately R90,000–R185,000). For smaller amounts, you may need to use a spot rate instead.

Check current mid-market rates before calling your bank's dealing desk — it helps you evaluate whether the quoted forward rate looks reasonable.

| Pros | Cons |
|---|---|
| Eliminates rand weakening risk on the hedged portion | You cannot benefit if the rand strengthens |
| Makes landed cost predictable for pricing and budgeting | Binding obligation — must be settled or closed out |
| Available from all major SA AD banks — no specialist needed | Minimum deal sizes may exclude very small transactions |
| Cost is modest relative to the risk removed | Does not cover shipment date risk (if goods are delayed) |
| Simple to book — a phone call or online banking | Forward premium adds slightly to the cost vs spot |
Frequently asked questions
How far ahead can I book an FEC?
Most South African banks offer FECs from 7 days out to 12 months forward, with some willing to go to 24 months for established customers with large facilities. The most common tenors for importers are 30, 60, 90, and 180 days. Longer tenors carry a higher premium because the interest rate differential compounds over more time.
What is an option forward or window forward?
A window forward (also called a time option forward) allows you to draw down the contract on any date within a range — say, between day 60 and day 90 — rather than on one fixed date. This is useful when you are not sure of the exact payment date. It typically carries a slightly wider spread than a fixed-date FEC.
What happens if my shipment is delayed and the FEC matures before I pay?
Call your bank's forex desk before the maturity date. They can "roll" the FEC forward to a new date — this involves closing the original contract and booking a new one. There may be a mark-to-market gain or loss on the roll, plus a new forward premium. Always monitor shipment progress against your FEC maturity date and communicate with your bank early.
Does an FEC replace the need for an APN?
No. An FEC is a currency hedging tool — it locks in the rate. The APN (Advance Payment Notification) is a SARS compliance requirement for advance payments above R50,000. If your payment is an advance payment above the threshold, you need both: the FEC to lock in the rate, and the APN to satisfy SARS exchange control requirements. See our APN guide for details.
Can an SMME access FECs or is this only for large corporates?
FECs are available to any business — small, medium, or large — that has an active forex facility with an Authorised Dealer bank. Some banks have minimum deal sizes that may exclude very small transactions (under USD 5,000). If your order sizes are small, ask your bank about "window forwards" or whether they have lower-minimum products for SMMEs. Many do, especially for established banking relationships.
