UK 10-year gilt yields hit post-crisis high; Healey faces £6bn fiscal hit

UK 10-year gilt yields surged up to 15bp, reaching their highest since the 2008 financial crisis, amid a global bond rout. This raises government debt interest costs by an estimated £6bn, pressuring Chancellor Healey's fiscal headroom. The move reflects broader global repricing rather than UK-specific factors, but it tightens fiscal constraints and could force policy adjustments.
