When to use this page

  • Testing whether a supplier quote still works if FX moves before payment.
  • Setting a quote buffer for cross-currency landed-cost or target-buy decisions.
  • Explaining the cash exposure behind a TT balance, LC payment, or open-account invoice.

Calculation assumptions

  • Current local cost = foreign-currency exposure x current exchange rate.
  • Adverse local cost = exposure x current rate x (1 + adverse move %).
  • FX buffer = adverse local cost - current local cost.

Before relying on the result

Reconcile the result against the full commercial file: supplier quote, Incoterm, payment term, freight quote, landed-cost model, and any official or bank-controlled source that governs the actual transaction.
