Iran's central bank governor has said that new US sanctions against the lender are a symptom of Washington's inability to exert "leverage", state news agency IRNA reported.
"The US adminstration sanctioning the central bank again shows how empty their hands are in finding leverage against Iran," IRNA quoted central bank governor Abdolnaser Hemmati as saying on Friday.
Washington has imposed a series of sanctions against Tehran since unilaterally pulling out of a multilateral nuclear deal in May last year.
US President Donald Trump announced new sanctions on Iran's central bank on Friday, calling the measures the toughest ever imposed on another country by Washington.
Hemmati contended that if US sanctions were effective, Iran's "economic condition would have been very different from what it is now."
