SINGAPORE, Nov 12 (Reuters) - Asian refining profit margins for 10 ppm gasoil weakened further on Tuesday, slipping to their lowest level in five months, weighed down by abundant supplies and weaker demand in the physical market. Refining margins or cracks for 10 ppm gasoil fell to $14.71 per barrel over Dubai crude during Asian trade, hitting their lowest levels since June 11. They were at $15.23 per barrel a day earlier. The gasoil cracks in Asia have come under pressure as some regional refineries, undergoing planned maintenance, are returning to production, while India is exporting more on the back of weaker demand in its domestic market. "There is a lot of marine gasoil (MGO) ex-Indian refineries in the market now ... In the short term, I think they will continue to export more gasoil as the domestic market cannot absorb the volumes," a Singapore-based middle distillate trader said. "There's too much of Indian gasoil looking for homes at the moment ... The Indian barrels would further worsen the existing supply overhang in the overall Asian gasoil market," she added. Indian state-run refiners including Indian Oil Corp, Mangalore Refinery and Petrochemicals and Bharat Petroleum Corp Ltd have all ramped up their gasoil exports in recent weeks. Cash premiums for gasoil with 10 ppm sulphur content GO10-SIN-DIF fell for a sixth straight session on Tuesday to a six-week low of 39 cents per barrel to Singapore quotes, compared with a 50 cent premium on Monday. Meanwhile, cash differentials for jet fuel JET-SIN-DIF widened their discounts to 56 cents per barrel to Singapore quotes on Tuesday, compared with a discount of 52 cents per barrel on Monday. Refining profit margins for jet fuel dropped to $15.05 per barrel over Dubai crude on Tuesday, their lowest in over four months. The cracks were at $15.62 per barrel on Monday.
