British Headline Inflation Surprises with Increase to Three Point Four Percent in December

The Office for National Statistics reported on Wednesday that headline inflation in the United Kingdom GBrose to 3.4 percent in December 2025, up from 3.2 percent in November. This reading exceeded the 3.3 percent median forecast suggested by economists in a Reuters poll and marked the first monthly increase in the headline rate since July 2025. Despite this uptick, the country's consumer price and services inflation rates are currently running slightly below the levels projected by the Bank of England in its November forecasts.
