Trump hits Iran with more sanctions. What will their impact be?

President Trump announced new sanctions on Tehran yesterday to further squeeze the Iranian economy in retaliation for what the U.S. says are recent acts of aggression, Edward Wong of the NYT reports.

• “The new sanctions are aimed at preventing some top Iranian officials from using the international banking system or any financial vehicles set up by European nations or other countries.”

• “The move came on top of actions taken by the administration this spring to cut off all revenues from Iranian oil exports.”

The new sanctions may have little effect. “Iranian officials most likely do not keep substantial assets in international banks, if any at all, or use those institutions for transactions, and any additional pressure from the new sanctions is likely to be minimal,” Mr. Wong writes.
