The Great British Pound (GBP — also known as Sterling or the Pound Sterling, symbol £) is the official currency of the United Kingdom — one of the world's oldest and most widely traded currencies, and the fourth largest reserve currency globally after the US Dollar, Euro, and Japanese Yen. The GBP is managed by the Bank of England, which sets interest rates through its Monetary Policy Committee (MPC) to maintain the 2% inflation target. For Indian financial markets, the GBP is the currency of one of India's most important trading partners — the United Kingdom — with significant bilateral trade in IT services, pharmaceuticals, gems and jewellery, textiles, and financial services. GBP/INR is one of four currency derivative pairs traded on Indian exchanges (NSE and BSE), enabling Indian businesses and investors to hedge Sterling exposure through regulated, rupee-settled contracts. The GBP has experienced significant volatility in recent years — particularly around the 2016 Brexit referendum (when sterling fell sharply against all major currencies including the rupee) and subsequent UK-EU trade relationship developments — creating both risk and opportunity for Indian exporters and importers with British pound exposure. Indian IT services companies — including Infosys, TCS, Wipro, and HCL — generate substantial revenues from UK clients, making GBP/INR movements a material factor in their rupee-denominated reported revenues, profit margins, and earnings per share calculations.
