Inflation in the UK has dropped to its lowest level in over three years, leading to expectations of a potential interest rate cut by the Bank of England. Consumer prices rose by 1.7% in September, down from 2.2% in August, primarily due to lower air fares and petrol prices, although food prices increased. The decline in inflation is below the central bank's target for the first time since 2021, prompting predictions of a rate cut in November. However, the lower inflation rate could negatively impact vulnerable households as benefits are tied to September's rate.
