SINGAPORE, May 21 (Reuters) - Asia's cash discounts for gasoil narrowed for a sixth consecutive session on Thursday amid firmer buying interests in the physical market, while Singapore middle distillate stocks hit a two-week low. Cash discounts for 10 ppm gasoil GO10-SIN-DIF were at 77 cents per barrel to Singapore quotes on Thursday, the smallest discounts since end-March. They were at a discount of 84 cents per barrel on Wednesday. Refining margins or cracks for gasoil with 10 ppm sulphur content rose to $5.58 a barrel over Dubai crude during Asian trading hours, 4 cents higher from Wednesday. Meanwhile, jet fuel cracks in Singapore edged higher to $1.73 a barrel over Dubai crude on Thursday, up from $1.54 a day earlier. European jet profit margins rose to minus 35 cents on Wednesday, the highest in three weeks, although imports to the region in May touched a one-year peak. A gradual increase in the number of flights in the region also supported the margins. Cash discounts for jet fuel JET-SIN-DIF widened by 6 cents to $2.61 a barrel to Singapore quotes on Thursday as the front-month spread widened its contango structure.
