Iran is hurting. Economic and banking sanctions, plus an effective oil embargo led by the European Union, have brought chaos to Iran's economy. The bottom fell out of its currency, the rial, a couple of weeks ago, provoking street protests. Iranians of all social classes are struggling to cope.

Large crowds of anxious Iranians gathered in Tehran on Sunday and Monday at foreign exchange offices — some of which had shuttered their doors — as Iran's currency continues its free fall.
