The quoted rate is not always the received rate
The amount deposited can reflect a conversion spread, provider charge, receiving-bank fee, and a different conversion date from the order. Model the path from marketplace currency to usable destination currency.
Build the conversion bridge
- Start with the expected disbursement in settlement currency.
- Apply a conservative exchange rate for the expected deposit date.
- Subtract percentage conversion costs and fixed transfer or bank charges.
- Compare the estimated deposit with the realized bank amount after settlement.
Match the buffer to the decision horizon
A price held for several months carries more currency risk than a short promotion. Supplier and freight payments in another currency can add a second exposure. Stress-test both revenue and cost currencies rather than applying one generic percentage.
Set a review trigger
Define the exchange-rate or realized-margin movement that requires a price, transfer, or sourcing review. Scheduled monitoring is more reliable than changing prices in response to every daily fluctuation.
