For most part of the year inflation remained above the Reserve Bank of India's tolerance level of 6 per cent before falling below RBI's upper end of the band in November. In April, retail inflation had touched an eight-year high of 7.8 per cent on a y-o-y basis, driven by escalating global commodity prices. This was the highest inflation noted since May 2014 prompting the government to implement supply side measures to combat high prices.
