Read the invoice currency
Trade can be priced in a third currency. An IMF working paper on invoicing patterns describes the US dollar as dominant in its sample, including transactions between countries outside the United States. For a price fixed in dollars, the immediate conversion into the buyer’s currency follows its dollar exchange rate. The seller’s currency still affects costs and the price it may set later.

Imagine a Brazilian buyer paying a Korean supplier USD 10,000. At BRL 5.00 per dollar, that invoice converts to BRL 50,000. At BRL 5.20 it becomes BRL 52,000, before fees and hedges, even if the real–won cross barely moves. The buyer’s final costs can differ if it locked its rate or the supplier reprices the contract.
Build the right exposure map
Separate the invoice, payment and reporting currencies. Record when the price resets, when the foreign currency is bought and whether the contract shifts exchange risk. This distinguishes a short-term conversion effect from the slower effects on margins, order volumes and sourcing decisions.
