About GBP/USD
What is the GBP/USD?
The British Pound (GBP) is the oldest currency still in use and the fourth most traded currency globally. The UK's economy is heavily services-driven, particularly financial services centered in London. GBP/USD is highly sensitive to Brexit developments, Bank of England policy, UK economic data, and political instability. The pair earned the nickname 'Cable' from the underwater telegraph cables that connected the UK and US in the 19th century, allowing exchange rate transmission.
