"The withdrawal of the United States from the agreement seems to be the beginning of the negotiation. It would impact Iranian oil sales between 300,000 and 1 million barrels per day, that’s sort of the range of estimates there," Dudley said on the sidelines of the St. Petersburg International Economic Forum (SPIEF).
Speaking about oil prices, Bob Dudley said he doubted that oil prices would reach $100 per barrel.
"There are people predicting that it will be $100 [per barrel], I don’t think it will be $100 unless there are geopolitical restrictions to the flow of oil, I mean conflict, and I don’t expect that," Dudley said.
Dudley said he believed that the agreement of the Organization of the Petroleum Exporting Countries and non-cartel producers on cutting oil production would be kept until the end of 2018.
SPIEF, held annually in Russia's second largest city of St. Petersburg, is a major global platform for communication between business representatives and the discussion of crucial economic issues.
