Iran's currency hit a record low on Sunday of 100,000 rials to the dollar amid a deepening economic crisis and the imminent return of full US sanctions.
The rial has lost half its value against the dollar in just four months, having broken through the 50,000-mark for the first time in March.
The handling of the crisis was one of the reasons behind last week's decision by President Hassan Rouhani to replace central bank chief, Valiollah Seif. The government attempted to fix the rate at 42,000 in April, and threatened to crack down on black market traders. But with banks often refusing to sell their dollars at the artificially low rate, the government was forced to soften its line
The currency collapse was precipitated by the US announcement in May that it was pulling out of the 2015 nuclear deal.
The unofficial rate stood at 102,000 rials by midday.
