The bad news is that it's probably just a cyclical trough. Says Shashank Bhide, head of research, National Council of Applied Economic Research (NCAER): "Inflation has touched its bottom. Now, prices are set to rise sharper till August-September after which the impact of a good monsoon may reverse the trend, unless there is a change in the pattern of primary articles. And if the rains are bad, then the situation will only get worse." Measured by the wholesale price index (WPI), inflation is more illusory than real. For one, it is singularly inefficient in reflecting the true cost of living for citizens. A better indicator is the Consumer Price Index for Industrial Workers (CPI-IW), a compilation made by the Labour Bureau, Department of Statistics, of retail prices of 260 commodities from all corners of the country. The CPI gives almost 50 per cent weightage to essential commodities, opposed to only 22 per cent by the WPI. But CPI figures do not come in handy as they always lag behind WPI by four months.
