For weekend transfers (or on some public holidays), we offer two exchange rate options because the financial markets are closed:
Next available rate
This option is free, but it means you won't know the exact exchange rate when you pay for your transfer. Instead, you'll get the live rate when the financial markets open.
Last known rate
This option is subject to a 0.1% fee and means you'll get the exchange rate that was available when the financial markets closed on the previous business day (most likely late on Friday evening).
Fees:
If you choose Standard delivery and specify an exact destination amount, you'll only be able to choose the Last known rate, because this is the only way to ensure the exact amount arrives.
If you choose Express delivery (including Instant), in addition to the 0.1% delivery fee applied, you'll only be able to choose the Last known rate.
Fees are always shown clearly when you are creating your transfer.
