The International Energy Agency slashed its forecast for global oil demand growth for the fifth time in the last six months on Friday and said the current slide in prices won’t dent global supply or hit demand, at least in the short term. Despite a slide of more than 40% in oil prices since June, the Paris-based energy watchdog said it still expects a robust increase in production from nations outside the Organization of the Petroleum Exporting Countries next year. “Barring a disorderly production response, it may well take some time for supply and demand to respond to the price rout,” the IEA said in its closely watched monthly report on the oil market.
