An exchange rate is the price of one currency in another. If the GBP/EUR rate is 1.15, one pound buys 1.15 euros. Rates change all day as currencies are bought and sold around the world.

Why exchange rates move

Rates move with supply and demand. Interest rates, inflation, economic news and politics all change how much people want to hold a currency, and so its price.

The rate you see vs the rate you get

  • The mid-market rate is halfway between the buy and sell prices on the wholesale market.
  • Providers usually offer a rate a little worse than that, and keep the difference.
  • Some also charge a separate fee, so compare the total you'll receive, not just the fee.

Reading a quote

A quote like GBP/USD 1.27 means one pound costs 1.27 dollars. The first currency is the base and the second is the quote currency. Flip the pair and the rate becomes 1 divided by 1.27.
