ISLAMABAD - The inflation based on Sensitive Price Indicator (SPI) recorded an increase of 10.38 per cent in the first week of current financial year over the corresponding period of last year mainly due to surge in petroleum prices. According to the figures released by Federal Bureau of Statistics on Saturday, the SPI based inflation surged by 1.12pc on weekly basis. Due to increase in POL products the prices of the kitchen items went up in the week ended on July 9. According to the official data, in the last week prices of 28 commodities ballooned and the majority of the goods were basic food commodities including vegetables, fruits and different pulses. On the other hand prices of only 5 commodities went down, while prices of 20 items did not show any change and remained same in the period under review. The economists believe that it would be difficult for the government to bring inflation in single digit at the end of the current year if the trend of increasing POL prices continues, as in their viewpoint the prices of food commodities would also shoot up after hike in petroleum products.
