The retail inflation rate climbed to a 14-month peak of 6.21 per cent in October, driven by a significant increase in food prices, particularly for fruits, vegetables, meat, fish, and oils and fats, according to data released by the National Statistical Office (NSO) on Tuesday. Food inflation, as measured by the Combined Food Price Index (CFPI), rose sharply to 10.87 per cent in October — the highest in 15 months — up from 9.24 per cent in September and 6.61 per cent in the same period last year.
