The rial firmed 1.7% to 1,716,000 per dollar on Rubio's 2 June testimony, but the gain was gone by the next close; it sits at 1,736,000 on 4 June, near its record low.

Key takeaway

The rial's testimony-driven rally vanished within a day, leaving it near its record low against the dollar.

The Iranian rial firmed 1.7% to 1,716,000 per dollar intraday on Marco Rubio's 2 June testimony , but that print did not survive the session. By the 3 June close it had retraced to 1,738,000, and it sits at 1,736,000 on 4 June 1. The rial is Iran's currency, and on the street market it has shed roughly 43% since the conflict began in February.

The Rubio bounce is gone, leaving the currency about 1.5% above its 1 June record low of 1,746,000 . The pattern mirrors the wider split running through 4 June: spoken signals move Iranian assets briefly, then fade because no paper follows. Rubio's Hormuz-first testimony lifted the rial for part of one trading day; nothing in it changed the sanctions regime or the war that is bleeding the currency.

A genuine, signed settlement would reset the rial for months, not minutes, which is what the brief rally underlines. Lloyd's of London makes the same point on the insurance side: its Joint War Committee needs an official UN or government certification letter, not a Senate hearing, before it touches its Hormuz cover, and it has stayed put.

Deep Analysis

In plain English

Iran's currency, the rial, has lost roughly 43% of its value against the dollar since the conflict began in February 2026. On 2 June, when the US Secretary of State Marco Rubio gave a Senate testimony suggesting talks were progressing, the rial briefly improved by about 1.7%, which is unusually large for a single day. But by the next day the gain had entirely reversed. The rial is being traded on Tehran's open currency market by ordinary citizens and businesses who desperately want dollars. The brief bounce happened because Rubio's words suggested a deal might be near. The reversal happened because the market quickly decided that words from a diplomat are not the same as a signed agreement. Without actual sanctions relief, which requires a full deal to be signed and officially certified, the rial has nothing structural supporting it.

Different Perspectives
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Israel
Israel
IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
Qatar
Qatar
Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.
Kuwait
Kuwait
Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.
United States
United States
Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
