Iran's rial hit 1,762,000 per dollar on Day 100, erasing the recovery deal optimism had bought.

Iran's rial hit 1,762,000 per dollar on Day 100, 7 June 2026, weakening from 1,736,000 on 4 June, according to the tracking service AlanChand 1. The rial is the free-market exchange rate ordinary Iranians use, and it is the cleanest daily read on how the country's own people price the war and the prospect of a deal. The latest fall extends the retreat documented on 4 June , when the currency reversed an earlier bounce tied to US testimony.

The slide erases the recovery that diplomatic optimism had bought over the prior fortnight. Each signal of a possible agreement had nudged the rate back; the Day 100 low unwinds all of it, leaving the currency near its record weak point after touching 1,746,000 on 1 June . The market is treating the talks as producing nothing tradeable, and the depreciation compounds the cost of imported food and fuel for households already squeezed by sanctions.

Deep Analysis

In plain English

Iran's currency, the rial, is the money ordinary Iranians use to buy food, medicine, and household goods. Many of those goods are imported, so when the rial weakens against the US dollar, everything bought from abroad costs more in rial terms. On Day 100 of the conflict, 7 June 2026, one US dollar costs 1,762,000 rials on the open market. Three days earlier it cost 1,736,000. Before the war began the rial was already under pressure, but the conflict and sanctions have accelerated the fall dramatically. Iran's own central bank reported inflation of 77.2% in the year to May 2026, the worst since the Second World War occupation of 1942, with daily-needs goods up 113% {{EVREF:/t/iran-conflict-2026/119/iran-inflation-at-worst-since-1942/}}. Currency traders use the rial as a real-time signal of how close a deal feels. When Rubio said the deal was '95% done' on 2 June, the rial briefly strengthened. By Day 100 that gain had completely reversed. The market's message is that signed paper has not arrived and may not arrive soon.

Deep Analysis
Root Causes

Iran's rial depreciation rests on a dollar-scarcity structural condition that predates the 2026 war. Under the maximum-pressure sanctions of 2018-2021 the rial fell from roughly 40,000 to the dollar to over 300,000; the conflict has accelerated the same dynamic by an order of magnitude.

The central mechanism is that Iran cannot freely sell oil for dollars, so it cannot maintain foreign-exchange reserves at the level needed to defend the currency. With reserves depleted and oil exports near zero, the open market rate reflects genuine scarcity rather than speculative attack.

Causes and effects
This Event
Rial hits new low on Day 100
The currency has unwound a fortnight of diplomatic hope, pricing the deal talk as worthless.
Different Perspectives
Gulf shipping and insurance markets
Gulf shipping and insurance markets
With Hormuz and Bab el-Mandeb both hostile at once, war-risk underwriters face their first dual-chokepoint pricing problem; the rerouting hedge that absorbed one closure is gone for Israeli-linked hulls. Any deal that reopens Hormuz without a Houthi stand-down clause delivers only partial shipping relief.
Russia and China
Russia and China
Russia and China met IAEA chief Grossi jointly in Geneva on 5 June to coordinate an advance blocking position against Washington's censure resolution, the first documented instance of proactive pre-session obstruction rather than reactive post-vote dissent. Beijing's move came four days after OFAC designated Shanghai Qianye Energy under Iran energy sanctions.
Saudi Arabia
Saudi Arabia
Saudi Arabia was left out of the emergency $4.01 billion Patriot waiver Qatar received on 2 May as its own PAC-3 stocks ran near-empty from intercepting Iranian salvoes over Aramco facilities. Riyadh is on a standard 18-month FMS queue behind a production line booked through 2030, with no equivalent priority to Qatar's Al Udeid basing role.
Houthis (Ansar Allah)
Houthis (Ansar Allah)
The Houthis declared a complete ban on Israeli Red Sea navigation on 8 June and struck Jaffa, their first attack on Israeli territory since April, seven days after the Tasnim authorisation to activate other fronts including Bab el-Mandeb. The declaration put both chokepoints under hostile authority simultaneously.
Iran
Iran
Iran agreed the 9 June mutual halt after the Mahshahr exchange and coordinated with Russia and China to block Washington's IAEA censure resolution, using the Board as a second front while the bilateral pause held on the military one. Tehran's acceptance of the Lebanon carve-out contradicts the linkage position it stated on 1 June.
Benjamin Netanyahu and the IDF
Benjamin Netanyahu and the IDF
Israel struck the Karun Petrochemical plant at Mahshahr on 8 June over Trump's explicit objection, then agreed a halt with Iran the following day scoped on Israeli terms with Lebanon carved out. Netanyahu's posture is that the IDF will not accept Iranian missile factories as off-limits regardless of US diplomatic timelines.
