Moreover, if "Iran violates the nuclear limits or refuses IAEA [International Atomic Energy Agency] inspections, then the E3 [in Europe] will have a responsibility to snap back sanctions under the JCPOA", Albright added. The U.S. wants to reduce Iran's oil exports to zero, but the waivers ensure this will not happen, at least in the short term.
The move will restore USA sanctions that were lifted under a 2015 nuclear deal negotiated by the administration of President Barack Obama, and add 300 new designations in Iran's oil, shipping, insurance and banking sectors. "We said that our economy should not be impacted by your policies", sources said.

When asked about his decision to give temporary exemptions to eight countries from the ban on Iranian oil imports, Trump said, "I'm not looking to be a great hero and bring it down to zero immediately".
Analysts have debated whether the dip was driven by decreased demand on the global market or whether Iran was exporting roughly the same total volume of crude but moving some 400,000 to 500,000 barrels per day to the black market - shifting a massive infusion of cash to its coffers.
Governor of the Central Bank of Iran Abdolnasser Hemmati said Iranian banks should use their previous experience dealing with sanctions to help the country's economic situation.
