Tuesday's 7% plunge in West Texas Intermediate (WTI) - the largest slump in more than 30 years of futures contracts - marked the 12th consecutive daily loss for the NY benchmark.

"While the countries buying the crude oil are going to pay more for the product, the oil producing countries are expected to make more money in the process", he said. USA output outstripped the production of Saudi Arabia and Russian Federation.
United States officials have already said the sanctions would be meant to bring down Iran's oil exports to zero.
He said emerging concerns about weak global demand, rising US production, and speculators rapidly bailing out of long positions were primary factors for the drop.
