Our Invest account is multi-currency.
It is possible to deposit funds in any of the supported currencies 
You can also withdraw funds in any currency. You can select one currency balance to withdraw from, and we will pay those funds in the selected currency. If the currency of your bank account is different from your withdrawal currency, your bank may charge you an FX fee.
HMRC regulations prohibit holding foreign currency in ISAs, Therefore, we cannot introduce the multi-currency feature in those accounts.
