GBP/USD — the British pound against the US dollar

The most widely quoted sterling pair, driven largely by the relative interest-rate and growth outlook of the UK and the United States.

GBP/USD is the pair most UK finance teams check first, because so many software subscriptions, cloud contracts and US-manufactured components are invoiced in dollars regardless of where the buyer is based. It is also one of the most heavily quoted pairs in the world, which means pricing is generally continuous and transparent across trading hours that span the UK and US business day.

For a UK business, the pair sits at the intersection of two large, closely watched economies. Diverging expectations for UK and US interest rates, growth and inflation are the recurring theme in commentary on it, and both economies publish a dense monthly calendar of data that traders and treasurers alike track.

Because dollar invoicing is so common outside the US itself — many commodity and tech contracts reference USD even between non-US counterparties — UK firms can carry GBP/USD exposure without a single American supplier or customer on their books.
