The U.S. campaign to economically isolate Iran is beginning to put Tehran under severe financial strain as a blockade chokes off oil revenue and expanded sanctions make it increasingly expensive for the country to obtain foreign currency, finance imports and circumvent restrictions.
Three senior Iranian sources told Reuters that the latest pressure is becoming increasingly difficult for the government to withstand. Iran has spent decades developing networks to work around Western sanctions, but Washington is now targeting many of the financial channels, intermediaries and trading arrangements that allowed those systems to function.
