Consumer price inflation based on the consumer price index for May 2015 rose to a two-month high of 5.01 per cent, up from 4.87 in April, showing that the Reserve Bank's concerns over price volatility could turn up to be true.
Consumer price index-based inflation was at 8.33 per cent in May 2014.
The uptick in inflation has been due mainly to a rise in the prices of pulses, which rose by 16.62 per cent in May 2015 over the same month last year, according to the data released by the Central Statics Office (CSO).
Domestic pulses production fell by nearly two million tonnes in 2014-15 crop year due to unfavourable weather conditions such as untimely rains.
