Pulses inflation has swung 8100 bps in latest cycle

Logs steepest peak and fall, compared with 12.2% trend rate since 2006

A recent study by CRISIL had found that inflation in pulses, as measured by the wholesale price index (WPI), shot up every 2-3 years in a cyclical pattern.

Since fiscal 2006 and up to the first four months of fiscal 2018, there have been four such cycles where the trend rate of inflation averaged 12.2%, with peaks 40% above the zero level and troughs 25% below.


Says Dharmakirti Joshi, Chief Economist, CRISIL Ltd, “The latest cycle, which began in fiscal 2013, has not only witnessed the steepest peak (49% in November 2015) and fall (-32.6% in July 2017), or a swing of 8100 basis points, but also broad-based price fluctuations (across different types of pulses) compared with the previous cycles, when inflation was driven by one type.”


What explains this?


This is the cobweb phenomenon at work, wherein production responds to prices with a lag, causing a recurring cycle of rise and fall in output and prices.


An analysis of the correlation between production and one-year lagged WPI inflation data for the past 12 years shows price cycles are triggered by both positive (excess production) and negative (under production) supply shocks. That’s because farmers decide on sowing based on prices in the previous season, and over- or under-produce, which sets off price cyclicality.


Profit margins of all pulses except gram declined an average 30% in agriculture year 2016-17, because of high production and restrictions on exports and private stockholding. So much so, during this cycle, prices of most pulses have fallen the most in the past 6 years.


The fall in domestic consumption demand caused by demonetisation may have further contributed to skidding prices. Despite an increase in minimum support price (MSP), and government procurement, wholesale prices of all pulses except gram declined sharply, while input costs continued to grow.


But prices of gram (chickpeas), which has a high share of 40-45% in overall pulses production and more than 60% in exports, bucked the trend, and shot up in the last six years while price rise in most others slowed.


That’s because, unlike other pulses, there is no restriction on exports of gram, so profitability remained higher for gram farmers as the international market was ready to absorb the excess domestic supply.


Says Dipti Deshpande, Senior Economist, CRISIL Ltd: “The pronounced cyclical patterns in pulses hurt both producers and consumers. It is time the government initiated steps to smoothen prices through a mix of effective MSP dispensation, open trade policy and well-functioning markets. Simultaneously, the crop needs to be de-risked by increasing the irrigation buffer.”
