The record low is increasing pressure on food prices and other costs have been making daily life that much more challenging for Iranians.
Prices are up on meat, rice and other staples of the Iranian dinner table.
Meanwhile, people worry about a new round of fighting between Iran and Israel - as well as potentially the United States - after June's 12-day war.
Iran's economy has been severely affected by international sanctions, particularly after US President Donald Trump unilaterally withdrew America from Tehran's nuclear deal with world powers in 2018.
At the time of the 2015 deal, which saw Iran drastically limit its enrichment and stockpiling of uranium in exchange for lifting of international sanctions, the rial traded at 32,000 to the dollar.
After Trump returned to the White House for his second term in January, he restarted his so-called "maximum pressure" campaign targeting Tehran with sanctions.
He again went after firms trading Iranian crude oil, including those selling at a discount in China.
In late September, the United Nations reimposed nuclear sanctions on Iran via what diplomats referred to as its "snapback" mechanism.
Those sanctions again freeze Iranian assets abroad, halt arms deals with Tehran and penalise any development of Iran's ballistic missile program, among other measures.
