Sterling has been a global currency for centuries, and its relationship with the dollar is one of the most important in finance. The two currencies are backed by large, developed economies with deep capital markets and central banks that actively manage monetary policy.
Major historical events have shaped this exchange rate. The 1992 Black Wednesday crisis saw the UK withdraw from the European Exchange Rate Mechanism. The 2008 financial crisis caused a sharp drop. Brexit in 2016 triggered one of the biggest single-day falls in the pound's modern history.
Understanding where the rate stands historically helps put today's number in context. If the rate is on the higher end of its recent range, British travelers to the US get more for their money. If it is lower, American goods and services become more expensive for British buyers.
