DUBAI – Iran’s rial currency fell to near-record lows Thursday as concerns grew in Tehran that European nations will start a process to reimpose United Nations sanctions on the Islamic Republic over its nuclear program, further squeezing the country’s ailing economy.

The move, termed the “snapback” mechanism by the diplomats who negotiated it into Iran’s 2015 nuclear deal with world powers, was designed to be veto-proof before the world body and would be likely to go into effect after a 30-day window. If implemented, the measure would again freeze Iranian assets abroad, halt arms deals with Tehran and penalizes any development of its ballistic missile program, among other measures.

In Tehran on Thursday, the rial traded at over 1 million to $1. At the time of the 2015 accord, it traded at 32,000 to $1, showing the currency’s precipitous collapse in the time since. The rial hit its lowest point ever in April at 1,043,000 rials to $1.

France, Germany and the United Kingdom warned Aug. 8 that Iran could trigger snapback when it halted inspections by the International Atomic Energy Agency after Israeli strikes at the start of the two countries’ 12-day war in June. Israeli attacks then killed Tehran’s top military leaders and saw Supreme Leader Ayatollah Ali Khamenei go into hiding.

Iran appears resigned

Iran initially downplayed the threat of renewed sanctions and engaged in little visible diplomacy for weeks after Europe’s warning, but has engaged in a brief diplomatic push in recent days, highlighting the chaos gripping its theocracy.

Foreign Minister Abbas Araghchi, speaking last week, signaled Iran’s fatalistic view of its diplomacy with the West, particularly as the Israelis started the war just as a sixth round of negotiations with the United States were due to take place.

“Weren’t we in the talks when the war happened? So, negotiation alone cannot prevent war,” Araghchi told the state-run IRNA news agency. “Sometimes war is inevitable and diplomacy alone is not able to prevent it.”

At issue is Iran’s nuclear enrichment

Before the war in June, Iran was enriching uranium up to 60% purity, a short, technical step away from weapons-grade levels of 90%. It also built a stockpile containing enough highly enriched uranium to build multiple atomic bombs, should it choose to do so.

Iran long has insisted its program is peaceful, though Western nations and the IAEA assess Tehran had an active nuclear weapons program up until 2003.

It remains unclear just how much the Israel and U.S. strikes on nuclear sites during the war disrupted Iran’s program.

Under the 2015 deal, Iran agreed to allow the IAEA even greater access to its nuclear program than those the agency has in other member nations. That included permanently installing cameras and sensors at nuclear sites. Other devices, known as online enrichment monitors, measured the uranium enrichment level at Iran’s Natanz nuclear facility.

The IAEA also regularly sent inspectors into Iranian sites to conduct surveys, sometimes collecting environmental samples with cotton clothes and swabs that would be tested at IAEA labs back in Austria. Others monitor Iranian sites via satellite images.

But IAEA inspectors, who faced increasing restrictions on their activities since the U.S. unilaterally withdrew from Iran’s nuclear deal in 2018, have yet to access those sites. Meanwhile, Iran has said it moved uranium and other equipment out prior to the strikes — possibly to new, undeclared sites that raise the risk that monitors could lose track of the program’s status.

On Wednesday, IAEA inspectors were on hand to watch a fuel replacement at Iran’s Bushehr nuclear reactor, which is run with Russian technical assistance.
