UK Inflation Rises to 3.5% in September, Raising Rate Hike Odds
Published on · Source: cnbc.com

AI Summary
Summarized by AI from the source belowUK inflation increased to 3.5% in the 12 months to September, higher than the expected 3.4%, driven mainly by a 29.8% surge in motor fuel prices. This was the highest annual inflation rate in nearly a year, continuing the upward trend from 3.1% in August and 2.9% in July.
The Office for National Statistics noted motor fuel inflation reached its highest level since August 2022. The UK, being a net energy importer, remains vulnerable to external energy shocks, including geopolitical tensions such as the U.S.-Iran conflict affecting oil movement through the Strait of Hormuz. Financial markets reacted with little change to the British pound and government bond yields after the inflation data was released.
J.P. Morgan's Scott Gardner highlighted concerns about rising services inflation, which might indicate broader inflation pressures beyond energy costs. Markets now assign a 98% probability of the Bank of England raising interest rates by 25 basis points (0.25%) to 4% next month, with further hikes expected in December. Meanwhile, growing inflation complicates fiscal management as the UK’s national debt exceeded £3 trillion ($4 trillion) in September, raising costs for debt servicing and challenging the government’s budget plans ahead of the Autumn Budget announcement.
