Iran's president sent a bill to parliament Wednesday that would cut four zeroes from the value of the Islamic Republic's sanctions-battered currency, the rial, as tensions remain high between Tehran and Washington.

By sending the bill to lawmakers, President Hassan Rouhani's government shows it is serious about an idea mulled for some time in Iran, where people discuss monetary transactions in both rials and informally but more commonly in tomans. A toman is worth 10 rials.

If passed by parliament and approved by lawmakers, Iran's Central Bank would in effect devalue the rial and rename it as toman.

The bank would have two years to create the new toman currency, returning a currency name that has not been officially used since the 1930s.

Authorities have given no estimate for the cost of creating the new currency.

Also, it was unlikely the parliament would take up Rouhani's request anytime soon. The request carried a low-urgency level, meaning parliament has up to two years, or until 2021, to deliberate and possibly approve the bill.

However, Iranians are to hold new parliamentary elections in March 2020, making it likely that the bill would be decided on by the next house and Rouhani may not see the new currency before the end of his presidency in 2021.

Nasim Souran, a Tehran-based financial journalist, told The Associated Press the proposal was part of Rouhani's policies to help the nation deal with increasing prices.

“This move can psychologically affect the lower-class people because they might feel that the value of their money has shrunk,” said Rahman Fatehi, 54, who works in a restaurant in Tehran.

“That's the psychological impact in my opinion but it won't negatively affect the economy. In fact, the current situation will remain unchanged.”

A 46-year-old Tehran resident, Ali Bagheri, believed that the bill will not change anything.

“Nothing will change (in the economic situation) by knocking off zeros from the currency,” he said. “Nothing will change by reviving coins in transactions.”

Iran's rial has been battered by escalating US sanctions on the country since President Donald Trump's decision to pull out of Tehran's nuclear deal with world powers over a year ago.

On Wednesday, the rial traded 116,500 to $1. At the time of the 2015 nuclear deal, the rial traded 32,000 to the dollar.

Iran's economy was long hobbled by years of sanctions over its nuclear programme, sparked by Western fears that Tehran could use it to build a nuclear weapon. Iran has consistently denied having any ambitions to build atomic bombs.

Other sanctions stem back to Iran's 1979 Islamic Revolution and the takeover of the US Embassy in Tehran, while the country also faced economic trouble amid and after its devastating 1980s war with Iraq.

As uncertainty over the Iran nuclear deal grew after Trump entered the White House, Iran's already anemic economy nosedived. The country's monthly inflation rate is at 40.4per cent and the national unemployment rate is some 12pc. Among youth, it is even worse, with around 25pc out of a job.

In 2018, money-exchange shops shut down for five months under a government order as it tried to control the rapid rial depreciation. It tried to enforce a government-imposed rate of 42,000 to $1 during that time.
