The first half of the Trump administration's new Iran sanctions strategy will kick in on Monday, restoring sanctions on any entity trading with Iran in gold, steel, aluminum, coal and other minerals and metals. The Trump administration will also restore sanctions on the Iranian automotive industry and on the issuing of Iranian debt or "significant" trade in Iranian currency.

Why this matters: Trump is moving ahead with his Iranian version of "maximum pressure" — though the end game, beyond a hope of unprecedented behavior change or regime collapse, remains unclear. These sanctions represent the first substantive move by the Trump administration after its May 8 withdrawal from the Iran nuclear deal.
