Influential forecasters gave a worsening outlook for the market, with the head of the International Energy Agency saying supply and demand won’t be in balance until late 2017 and Goldman Sachs Group Inc. cutting its fourth quarter price forecast.

Oil has fluctuated since rallying in August on speculation major producers will agree on ways to stabilize the market when they meet Wednesday.
