Tax, fees & accounts

Currency conversion fee

Also called FX spread

What a broker charges to convert between currencies when you buy foreign assets.

How it works

The charge is often expressed as a percentage margin on the interbank rate rather than as a separate fee, which makes it easy to miss.

It applies on the way in, on the way out, and frequently on every dividend received in a foreign currency.

Where it misleads people

A 1% conversion margin on a round trip is 2%, deducted before any return. On short holding periods it can exceed every other cost combined.
