The British pound sterling has extended its losing streak to a sixth consecutive session, sliding against a broadly stronger US dollar in a move driven entirely by American economic data and expectations, with no direct catalyst from the UK economy or domestic policy. The recent decline in GBP/USD is a textbook example of a dollar-driven currency move. The greenback has rallied sharply over the past week, buoyed by stronger-than-expected US employment figures and persistent inflation readings that have pushed back expectations for Federal Reserve rate cuts. As of the latest trading session, the dollar index has climbed to its highest level in several weeks, pulling nearly every major currency lower against it — including the pound.
