Read: Petrol price hiked by Rs. 1.69/litre, diesel by 50 paise Each non-subsidised 14.2-kg cooking gas cylinder will now cost Rs. 922.50 in Delhi, up from Rs. 906, according to Indian Oil Corp (IOC), the nation's largest oil firm. Non-subsidised LPG rates were last month cut by Rs. 23.50 per cylinder. A subsidised LPG cylinder in Delhi costs Rs. 414. Tuesday's hike breaks the declining trend that started in February with a Rs. 107 cut in rates to Rs. 1,134 per cylinder. It was followed by a Rs. 53.5 per cylinder reduction in March to Rs. 1,080.50, by Rs. 100 to Rs. 980.50 in April, by Rs. 52 in May and by Rs. 23.50 cut last month. IOC said losses on LPG have risen to Rs. 449 per subsidised cylinder from Rs. 432.71 in the previous month. The loss was Rs. 762.50 in January. Separately, the price of jet fuel or aviation turbine fuel (ATF), at Delhi was increased by Rs. 413.78 per kilolitre (kl), or 0.6%, to Rs. 70,161.76 per kl. The increase follows three straight monthly reduction, the last one of Rs. 1,285.89 per kl, or 1.81%, which came into effect on June 1. In Mumbai, jet fuel costs Rs. 72,411.21 per kl as against Rs. 71,940.36 per kl previously, IOC said. The rates vary because of differences in local sales tax or VAT. Jet fuel constitutes over 40% of an airline's operating costs and the price hike will increase the financial burden of cash-strapped carriers. No immediate comments were available from airlines on the impact of the price increase on passenger fares. The three fuel retailers — IOC, Hindustan Petroleum Corp and Bharat Petroleum Corp — revise jet fuel and non-subsidised LPG prices on the first of every month, based on the average international prices in the preceding month.
