The International Energy Agency said Thursday unexpected disruptions like Canada's wildfires could help reduce a global oil glut. The IEA also said that demand will expand due to increasing gasoline consumption this summer.

The IEA predicted that output from non-OPEC producers would fall an estimated 800,000 barrels per day this year. That's up from the agency's earlier forecast of a 710,000 barrel per day decline.

The IEA left its forecast for global demand growth broadly unchanged at 1.2 million bpd for this year. But it said that risks to future forecasts lay to the upside.
