Bangladesh's annual inflation rate climbed to 11.29 per cent in August due to non-food prices as Ramadan festivities boosted spending on items from clothing to furniture,government data showed on Thursday. Annual inflation in July had climbed just short of 11 per cent,the highest rate since January 2008,on the back of surging food and non-food prices alike. Food inflation edged down to 12.70 per cent in August from 13.40 per cent in July. But non-food inflation rose to 8.76 per cent from 6.46 per cent. Persistent inflation prompted the central bank to raise its key interest rates by half a percentage point earlier this month,its fourth hike since March.
