Iran's Central Bank chief Mohammadreza Farzin blames 'psychological operations' abroad for the sharp decline of the country's currency.

"They published a negative story every few hours," Farzin asserted, referring to US outlets that he said systematically derail his measures.

The Iranian rial plunged to a historic low against the US dollar on Wednesday, exceeding 780,000 rials per dollar. This marks a nearly 50% decline in the currency's value over the past year.
