Appendix 8: Applying Fees to FX Transactions

This section provides details of how fees are applied for foreign exchange (FX) transactions.

  • Where the transaction amount is in a non-domestic currency, the card scheme (e.g., Visa, Mastercard or Discover) applies their daily exchange rate to convert this to the billing amount in the card's domestic currency.

  • The Thredd Fees module fixed fees and fee rates are applied to the billing amount in the card's billing currency.

  • If the non-domestic minimum fee exceeds the combined value of the non-domestic fixed fee and non-domestic fee rate, then Thredd will apply the non-domestic minimum fee.

  • If the non-domestic minimum fee is lower than the sum of the non-domestic fixed fee and non-domestic fee rate, then Thredd will apply the fee which includes the combination of non-domestic fixed fee and non-domestic fee rate.
