UK Inflation Rises to 3.5% in September, Driven by Energy Prices

Inflation in the United Kingdom climbed to 3.5% in September, marking a third consecutive monthly increase and exceeding economists' expectations. The acceleration, detailed in figures from the Office for National Statistics (ONS), was primarily driven by a surge in energy and diesel prices, reflecting ongoing global economic pressures.

The Consumer Prices Index (CPI) rose from 3.1% in August to 3.5% in September. Core CPI, which excludes volatile items like energy, food, and alcohol, also saw an uptick, rising to 2.8% from 2.6%. Services inflation increased from 3.4% to 3.7%.

Key Inflation Drivers

Fuel prices were identified as the main contributor to the headline rate's increase. The average price of petrol reached 169.5p per litre in September, an 8.2p increase from August and the highest level since August 2022. This trend is expected to continue as Brent crude oil prices remain above $100 a barrel.

While food prices saw their lowest annual increase since September 2021, remaining unchanged at 1.3%, experts warn that continued pressure on gas prices could eventually affect supermarket costs. ONS Chief Economist Grant Fitzner noted that increased fuel costs were the primary driver, with diesel prices hitting their highest point since July 2022. Other upward pressures included airfares and, to a lesser extent, computer games and live events. These were partially offset by lower-than-usual price increases for hotel stays.

Impact on Consumers and the Bank of England

Higher inflation means the cost of living is increasing at a faster rate. The Bank of England's target for inflation is 2%. The current figures, peaking at 11.1% in October 2022, have significantly impacted household budgets. A sustained period of high inflation erodes the real value of savings and wages.

The Bank of England's primary tool for controlling inflation is by raising interest rates. The latest inflation data strengthens the likelihood of a rate hike at the next Monetary Policy Committee meeting. Markets are anticipating further rate increases, which have already contributed to rising mortgage costs for homeowners.

Future Inflation Outlook

Economists are divided on the future trajectory of inflation. Some, like those at ING, predict inflation to reach 4% this winter, suggesting that the rise in energy prices has not yet broadly impacted other goods and services. However, others, such as Martin Beck of WPI Strategy, believe the situation is more complex than just an energy shock, pointing to rising services inflation and anticipating further increases as energy prices rise again.

Rob Wood, chief UK economist at Pantheon Macroeconomics, forecasts headline inflation to peak at 4.8% in February and remain above 4% until July. This level is considered a threshold where
