According to industry body PHD Chamber, the consistent decline in WPI indicated "that the government has undertaken effective measures at the ground to address the supply side problems of the economy during the last few years".
"A significant decline in the inflation of food articles including cereals and pulses is an indicator that the government has rightly focused agriculture sector," Anil Khaitan, President, PHD Chamber was quoted as saying in a statement.
"Going ahead, we look forward to the continuation of favourable policy environment and further easing of monetary policy to strengthen the industrial growth and lower cost of borrowings for the businesses especially for the MSMEs."
Sunil Kumar Sinha, Director, Public Finance and Principal Economist, India Ratings said: "Unlike the retail inflation which dipped by 16bp in March 2018 over the previous month, the wholesale inflation remained flat."
"However, there are some noticeable changes at the disaggregate level. Inflation in the food article category which has been declining since November 2017 turned into deflation in March 2018 mainly driven by the sharp correction in the prices of fruits and vegetable."
Aditi Nayar, Principal Economist, ICRA said: "A downturn in food and mineral prices helped to offset the unfavourable base effect and keep the wholesale inflation steady at 2.5 per cent in March 2018."
"After the surge seen in the previous month, the core-WPI inflation eased to a three month low 3.6 per cent in March 2018 from 3.9 per cent in February 2018, reflecting a favourable base effect as well as the trend in a number of sub-sectors with a substantial weight such as textiles, basic metals, fabricated metal products, and motor vehicles, trailers and semi-trailers etc."
