Key takeaway

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.

The rial's Day 100 level of 1,762,000 per dollar represents a deterioration from the 1,716,000 Rubio-optimism floor of 3 June and is within 1% of the 1 June record low of 1,746,000 . The round-trip erasing deal-optimism gains follows a pattern visible across all five diplomatic windows in this war: the market prices verbal signals sharply, then unwinds them within 48-72 hours when no signed instrument follows.

The structural pressure driving rial depreciation runs through three channels simultaneously. First, oil export revenue has collapsed to below 300,000 barrels per day from 1.84 million bpd before the war, cutting the primary hard-currency inflow by roughly 84%.

Second, OFAC's Economic Fury sanctions have closed crypto and LPG smuggling rails the Central Bank was using to defend the exchange rate . Third, inflation at 77.2% annually, with some items past 300%, creates domestic currency flight as Iranians convert rials to gold, dollars or food before purchasing power erodes further.

For oil-importing countries, the conflict premium in Brent Crude near $97 translates directly into elevated petrol and food prices. The rial's collapse is Tehran's problem; the oil premium is the rest of the world's.

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

Oil traders

Sent Brent down 2.29 per cent to $98.38 a barrel on reports that mediation was reviving, moving the price on CENTCOM's quiet night rather than on Trump's same-day promise of a bigger operation with no deadline attached.

Iran

An Iranian official called the same mediation account completely misleading, denying it received any US proposal via Baghdad on the same day Iraq denied delivering one, leaving neither denial able to settle what actually passed between the two capitals.

Iraq

Called groundless the New York Times account that its prime minister carried a US ceasefire proposal to Tehran, a denial that also protects Baghdad's effort to avoid becoming a party to a war fought by aircraft it does not control.

OHCHR

Recorded 17 civilian seafarer deaths since the war began, a population neither the Pentagon nor Iran's Health Ministry counts in its own tally, and called for urgent action on 6,000 crew stranded across roughly 400 vessels in the Strait of Hormuz.

Houthis

Enforced the blockade on Saudi-linked shipping it declared on 20 July by hitting the NCC Masa and then an Aramco facility at Jazan, moving from radio warnings to strikes on land after four days without a confirmed hit.

Saudi Arabia

Struck Houthi military sites near Hodeidah the same day the NCC Masa was hit, while its coalition spokesman insisted Hodeidah, Ras Issa and Salif all remain open to navigation. The distinction protects the ports Yemen's population depends on for food and fuel even while punishing the group behind the tanker strike.
