You can invest in Fractional Shares with underlying stocks and ETFs in our catalogue which are traded in USD or EUR currencies. The Fractional Shares, however, are denominated in EUR only. That means if you want to invest in a Fractional Share with an underlying that is traded in USD, you'll pay for it in EUR.
The currency exchange rates applicable to the purchase and sale of the underlying stocks and ETFs are provided by Morningstar Inc. We apply a 0.5% mark-up to the exchange rate to cover currency exchange costs. We display this in the order confirmation screen in the app and in our pricing schedule.
