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 said he wants to negotiate a nuclear deal with Iran. Trump's comments come after he directed the Treasury and State Departments to drive the Islamic Republic's oil exports to zero.
