The Office for National Statistics (ONS) reported that the Consumer Prices Index (CPI) rose to 3.5% in the year to September, up from 3.1% the previous month. The main driver was motor fuel costs, with petrol prices rising 8.2p per litre to 169.5p, the highest since August 2022. Diesel rose to 192.5p per litre. Overall, motor fuel prices increased by 29.8% over the period. The figures come ahead of Chancellor John Healey's first Budget. Separately, the ONS said government borrowing reached £25 billion in September, £1.8 billion higher than a year earlier, partly due to higher debt interest costs linked to inflation.

The UK's inflation rate jumped to 3.5% in September, up from 3.1% in August, driven by sharp increases in petrol and diesel prices, according to official figures. The rise comes as global oil supplies remain squeezed by conflicts in the Middle East and Europe, and as government borrowing rose to £25 billion for the month.

How it's landing
UK inflation jumped to 3.5% in September (up from 3.1% in August), topping the consensus forecast and hitting its highest level this year. The release reinforces the broader global theme: inflation re-accelerated in September, due mainly -- but not exclusively -- to higher energy prices. #economy #markets #inflation #uk

Analysis
Why This Matters
- UK households face higher fuel costs, adding to living expenses just before the autumn Budget.
- Rising inflation complicates the government's fiscal plans, as higher debt interest costs reduce room for spending.
- The data may influence the Bank of England's interest rate decisions in the coming months.
Background
Inflation has remained above the Bank of England's 2% target for much of 2026, driven by energy and food prices. Global oil markets have been disrupted by ongoing conflicts, pushing up transport and manufacturing costs. The ONS data provides a snapshot of the economy ahead of the Budget, where the government is expected to outline tax and spending plans.
Key Perspectives
Consumers: Higher petrol and diesel prices directly increase the cost of commuting, heating and goods transport, squeezing household budgets. Government: Rising borrowing costs and inflation pressure limit fiscal headroom ahead of the Budget, making tax or spending decisions more difficult. Economists: The data suggests inflation may be stickier than expected, potentially delaying interest rate cuts by the Bank of England.
What to Watch
- The Budget announcement for measures to address cost-of-living pressures.
- Bank of England's next monetary policy meeting for any rate changes.
- Global oil prices and Middle East developments for further fuel cost increases.
