Oil prices were steady on Friday, but on track for a fall of up to 5% for the week on growing concern that fuel demand will weaken as the spread of a respiratory virus from China that has killed 25 so far dents travel and darkens the economic outlook. On the supply side, U.S. crude oil and distillate inventories fell last week while gasoline stockpiles grew for an 11th consecutive week to an all-time high, the Energy Information Administration said on Thursday. Crude inventories fell 405,000 barrels in the week to Jan. 17, government data showed, less than analysts’ expectations in a Reuters poll for a 1 million barrel drop. In a note on a Friday, ANZ Bank warned that further spread could crimp energy demand from the transportation sector.
