US sanctions strand Iran, Russia oil on tankers, driving up crude costs
The amount of Russian and Iranian oil held on ships has hit multi-month highs as harsher U.S. sanctions reduced the number of buyers, leaving fewer tankers available to deliver cargoes and driving up crude costs, trade sources and analysts said. Washington has imposed multiple rounds of sanctions on ships and entities dealing with oil from Iran and Russia since October, disrupting trade with major importers China and India. U.S. President Donald Trump last week restored his "maximum pressure" campaign on Iran that includes efforts to drive its oil exports down to zero in order to stop Tehran from obtaining a nuclear weapon.
