Surge in prices of metal and food items pushed inflation rate growth by 6.68 per cent, the highest ever in the past one year, dashing hopes of a softer interest rate regime in the near future.

After remaining close to 4 per cent in recent months, inflation has begun moving upwards, and surged by 0.76 per cent during the week ended March 15. It was 5.92 per cent in the previous week and 6.56 per cent in the corresponding period last year.

In line with the global trends, metal prices continued to be more expensive.

Food items, like vegetables, rape seeds and mustard oil also turned costlier.
