Iran rial plunges to 1.95 million per dollar as ceasefire unravels

Iran's currency has lost more than half its value since the US-Iran war began in February, as renewed hostilities crush hopes of a diplomatic resolution.

Iran's rial slid to a record low of 1.95 million per dollar on Sunday, extending a collapse driven by renewed US military pressure and the unraveling of a month-old interim ceasefire.

"The rial's decline reflects a complete loss of confidence in both the currency and the government's ability to stabilize the economy through diplomacy," said Esfandiar Batmanghelidj, senior fellow at the European Council on Foreign Relations.

The currency has lost more than 50% of its value since the US launched airstrikes on Feb. 28, with the collapse accelerating after the June 17 memorandum of understanding brokered by Pakistan fell apart. Iran's economy faces 68.9% projected inflation, according to the latest IMF estimates, as US sanctions and a naval blockade choke oil exports — the country's primary source of foreign currency.

The rial's freefall threatens to deepen a humanitarian crisis in Iran while giving Washington additional leverage as it seeks to force Tehran back to negotiations over the Strait of Hormuz, through which 20% of the world's oil flows. With midterm elections approaching, Trump faces pressure to show progress, but analysts say the military-first approach has so far failed to produce concessions.

Ceasefire Collapse Resets Diplomatic Clock

The June 17 MoU, signed by President Donald Trump and Iranian President Masoud Pezeshkian with Pakistani Prime Minister Shehbaz Sharif as mediator, established a 60-day negotiating framework to resolve the Strait of Hormuz dispute and reopen the waterway to commercial shipping. Within 25 days, both sides had accused each other of violating its terms.

Iran resumed attacks on tankers it claimed were transiting without permission, while Washington revoked a waiver allowing Iranian oil sales and reinstated a naval blockade of Iranian ports. US airstrikes have since hit at least 10 Iranian provinces, killing a soldier and several civilians, according to Iranian authorities. Iran retaliated by launching missiles and drones at Gulf states hosting US bases, with debris from interceptions injuring three people in Qatar.

The last time a US administration attempted a similar dual-track strategy of maximum pressure and limited military strikes was during the 2019-2020 tanker war in the Persian Gulf, when attacks on commercial shipping pushed Brent crude above $75 a barrel and widened credit-default swaps on Gulf sovereign debt. Brent has already risen 18% since the current conflict began, with the risk premium embedded in options skew reaching levels not seen since the 2022 Russia-Ukraine invasion.

Strait of Hormuz Remains the Core Dispute

At the heart of the breakdown is a fundamental disagreement over who controls passage through the Strait of Hormuz. Iran interprets the MoU as recognizing its authority to manage shipping transit, potentially through a fee or toll system. The US and its Gulf allies insist on a return to free passage under international maritime law.

Tehran has also signaled it could ask its Houthi allies in Yemen to close the Bab al-Mandeb strait at the mouth of the Red Sea if Washington strikes Iranian power infrastructure — a threat Trump has made repeatedly. Such a move would compound disruptions to global energy supply chains, particularly as some shipments have already been diverted to the Red Sea route.

VP JD Vance acknowledged in a podcast interview this week that diplomacy may be the only sustainable path forward. "You've got to actually be willing to talk and to try to figure out the problem," he said, adding that military force is "one of the many tools" available. Pakistan, Qatar and Oman continue backchannel mediation efforts, though regional officials acknowledge the 60-day negotiating process has effectively halted.

For Iran, the rial's collapse adds economic urgency to a strategic standoff. With inflation projected at 68.9% and foreign reserves dwindling under the blockade, the cost of maintaining its position on the strait rises with every percentage point the currency falls. For Washington, the question is whether more bombing will accelerate a diplomatic breakthrough or simply harden Tehran's resolve — a pattern that has repeated itself three times since the war began.
