What is British Pound (GBP)?
The pound sterling (GBP) is the world's oldest currency still in use and the fourth-most traded. Managed by the Bank of England (BoE), GBP is closely watched as a barometer of UK economic health and post-Brexit trade dynamics. GBP/USD ("cable") is among the most liquid major pairs.
Why it matters for investors
Sterling moves affect UK importers and exporters, FTSE 100 multinationals (which earn ~75% of revenue overseas, so weak GBP boosts FTSE 100 earnings), and London's status as a global financial center. Brexit-era volatility has made GBP one of the more event-sensitive G10 currencies.
