President Donald Trump’s recent decision to reinstate a goal from his first presidency to bring Iran’s oil exports to zero has had little impact on crude prices so far.

U.S. President Donald Trumpon Tuesday 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.

President Donald Trump signed a presidential memorandum to impose “maximum pressure” on Iran, a campaign that — during his first term — levied intense sanctions on the country in hopes of bringing it back to the negotiating table for nuclear talks.
