Can I fund my account in different currencies? Updated February 28, 2023 11:12 You can fund your account in a currency other than the account currency. Deposits in any currency which differ from your base account currency will be subjected to a conversion fee. The conversion fee is calculated by using the mid-spread FX spot rate* at the time of transfer, plus/minus the rates that you can find in the Currency Conversion Fees Section. *Spot rate refers to the inter-bank rate at the point of execution.
