After Trump pulled out of Iran deal, sanctions-hit nation lost $2 billion in oil revenue

Iran has lost around $2 billion in oil revenue since May when U.S. President Donald Trump pulled out of the nuclear deal, U.S. Special Representative for Iran, Brian Hook, told reporters on a call on Monday.

"We have taken 1 million barrels (of oil) off the market and that alone will reduce the Iranian regime's oil revenues by $2 billion," he said.
