What happened
UK inflation jumped to 3.5% in September, data showed on Wednesday, above the 3.4% forecast, as diesel hit its highest price since 2022 and markets now price two Bank of England rate hikes. Inflation is how fast prices rise over a year, and it was 3.1% in August. The cost of services, which covers things like rent, rose 3.7%, up from 3.4%. Diesel averaged 192.5 pence a litre as tensions around Iran pushed up fuel costs.
Why it matters
UK inflation at 3.5% means everyday costs are rising faster, and the Bank of England is widely expected to lift its interest rate from 3.75% to 4% on 5 November. Higher rates can make loans and mortgages costlier, while savers may earn more. Markets also expect a second increase in December. The Bank's own forecast is for inflation of about 3¾% by the end of 2026.
