Iranian activists on Monday called on President Hassan Rouhani to step down quietly and to hold early presidential election amid dire economic conditions.
Activists said that the interests of the country fell a victim of the political conflict between the different political blocs and parties.
If this situation continued it will cost the country too much, activists said.
The Iranian currency has been sliding for months because of a weak economy, financial difficulties and heavy demand for dollars amid fears of renewed US sanctions after President Trump withdrew the nuclear deal in May.
The dollar was being offered for as much as 87,000 rials, compared to around 75,500 on Thursday, the last trading day before Iran’s weekend, according to foreign exchange website Bonbast.com.
The rial has weakened from around 65,000 rials just before Trump’s announcement of the U.S. withdrawal in early May, and from 42,890 at the end of last year - a freefall that threatens to boost inflation hurt living standards and reduce the ability of Iranians to travel abroad.
In an effort to halt the slide, Iranian authorities announced in April they were unifying the dollar’s official and black market exchange rates at a single level of 42,000 and banning any trade at other rates under the threat of arrest.
But this step has failed to stamp out the unofficial market because authorities have been supplying much less hard currency through official channels that consumers are demanding.
The currency's fall also prompted traders at two shopping centres in Tehran that specialise in mobile phones to go on strike in protest on Sunday.
On Monday, traders at Tehran's Grand Bazaar have taken part in a big protest against rising prices and the plummeting value of the rial.
Shops were shut and thousands of people took to the streets of the capital.
Riot police later fired tear gas to disperse the demonstrators as they marched towards parliament.
Information and Communications Technology Minister Mohammad Javad Azari-Jahromi said the merchants returned to work after he promised to help them access hard currency for their imports.
There were also large-scale anti-government protests fuelled by Iran's economic problems in late December and early January.
Recent reports warned of the explosion of the economic situation, warning of rising inflation to two digits again.
Iranians who are fed up with the dire economic situation confirmed that Rouhani step down is the only solution for the crisis, calling for early presidential elections.
