"Cable" is a term used in foreign exchange markets to refer to the currency pair of the British Pound (GBP) and the US Dollar (USD). The name originates from the telegraph cables that were used in the 19th century to transmit exchange rates between London and New York. Traders closely monitor this pair due to its liquidity and volatility, influenced by factors such as economic data, political events, and central bank policies in the UK and the US.
