At 0.03%, Interactive Brokers has the lowest outright currency conversion or foreign exchange (FX) costs of all the investment platforms we cover at Good Money Guide. However, given that every broker has a slightly different fee structure, it may not be the best platform for you.
In this guide, we’ll provide a comparison of UK investment platforms’ FX charges and explain how fees can differ between platforms. Whether you’re an experienced investor or just starting out, this guide should help you reduce your FX fees and pocket more of your trading and investment gains.
Why do you get charged FX fees when buying international stocks?
When you buy or sell international stocks like Apple and Amazon in the UK, you typically have to pay foreign exchange (FX) fees. The reason for this is that you have to exchange your domestic currency (GBP for UK investors) for the foreign currency in which the stock is denominated (USD, EUR, AUD etc.) and brokers usually charge a fee for this service.
FX fees and charges can vary depending on several factors though. These include:
- The investment platform you’re using – different brokers have different fee structures.
- The account type – your account type (retail, professional, individual, corporate, etc.) may influence the FX fees charged.
- The size of the trade – larger transactions sometimes incur lower percentage FX fees.
Why are foreign exchange charges important when buying foreign stocks?
If you’re planning to buy and sell international stocks, it’s important to do some research into platforms’ FX charges. Because these fees can be substantial. Today, some UK investment platforms charge FX fees of around 1%. On a £10,000 international stock purchase, that translates to a fee of £100, which is significant.
