GBPUSD is a currency pair that represents the value of the British pound against the US dollar.

The pound, the currency issued in the United Kingdom, is one of the four major currencies. According to the 2022 BIS Triennial Central Bank Survey, the pound ranks fourth in trading volume, following the Japanese yen. Additionally, the GBPUSD pair has the third-highest trading volume among all currency pairs, while EURGBP ranks tenth. Although the pound ceded its status as the world's primary reserve currency to the US dollar after World War II, it remains actively traded worldwide.

The US dollar, issued by the United States, is circulated worldwide and holds the largest share in global foreign exchange. The 2022 BIS Triennial Central Bank Survey states that currency pairs involving the US dollar account for 88.4% of all currency trading. Additionally, many countries adopt the dollar-peg system, meaning their currencies are tied to the value of the US dollar. According to the 2022 IMF report, 37 countries and regions use the dollar-peg system, accounting for approximately 20% of IMF member states.
