Iran's Rial Hits Record Low as US Naval Blockade Halts Oil Exports

Iran's currency fell to a fresh record low in early October 2026, with the US dollar trading as high as 2.695 million rials on the free market, according to currency-tracking sites bon-bast.com and alanchand.com, as reported by Reuters via Arab News. That marked a further slide from 2.632 million rials a day earlier, and from about 1.1 million rials a year before, according to Iran International.

The decline accelerated through 2026. The rial traded near 920,000 to the dollar in August 2025, crossed 1.5 million at the start of 2026, and reached 2.2 million on September 2 before falling further later that month, according to Fortune and Iran International, both citing market data. For comparison, one dollar bought about 35,000 rials in 2018, Fortune reported.

Why the rial is collapsing

The principal driver is a US naval blockade of Iranian ports that began on April 13, 2026, after talks in Islamabad failed to end a war that started on February 28 with US-Israeli airstrikes, according to Wikipedia's entry on the blockade. The blockade was briefly lifted in June and reinstated on July 14. By September it had cut Iran's new crude loadings to zero, according to tanker-tracking data cited by Fortune and Iran International — the first month without loadings since Iran's 1979 revolution, according to Kpler oil analyst Homayoun Falakshahi, quoted by Fortune.

Oil normally supplies about one-third of the Iranian state budget, Fortune reported. Roughly 90 million barrels that were already at sea when the blockade resumed in mid-July are expected to be exhausted by mid-October, with payments for earlier cargoes potentially delayed until December because of restricted access to foreign banking channels, Fortune reported.

Washington also widened sanctions beyond Iran's oil sector during the week, extending measures to the country's automotive and rail industries in addition to the existing naval blockade, according to Iran International. US Treasury Secretary Scott Bessent pointed to the rial's collapse as a sign that the pressure campaign was working, the same report said.

Central bank response and official reactions

Iran's state banks began selling up to $2 billion to slow the rial's fall, Reuters reported via Arab News. Mehdi Darabi, an aide to the central bank governor on foreign exchange affairs, said the drop was partly caused by what he called false predictions from US officials about the collapse of Iran's economy, and described the fall as temporary, according to the same Reuters report.

Iran's central bank separately linked the exchange-rate volatility to rising uncertainty, psychological pressure among market participants and shifting expectations, according to Iran International. Economy Minister Ali Madanizadeh said external actors wanted to create unrest so that people would rush to the currency market and push the exchange rate higher, Iran International reported.

US Secretary of State Marco Rubio said Iran's economy was heading toward a severe collapse, adding that sanctions were intended to prevent Tehran from funding weapons development, according to Fortune.

Impact on prices and households

Iran's year-on-year inflation stood at 89.8% according to one measure cited by Iran International, while Reuters, via Arab News, put the rate at more than 70%. Food prices rose 127.5% year-on-year as of August, Iran International reported. Fortune separately cited a 2026 GDP contraction forecast of 5.4%.

Iran's monthly minimum wage of 166 million rials converts to roughly $66 at the record-low rate, Iran International reported, adding that an average monthly wage covers less than one-third of basic household costs. In Isfahan's Amir Kabir heavy-vehicle repair hub, activity fell about 30% year-on-year, according to the same report, which also said more than 6,000 people had been arrested since the war began amid concern about protests.

Background: blockade and war

The naval blockade followed a war that began on February 28, 2026, when US and Israeli airstrikes killed Iran's Supreme Leader Ali Khamenei and other officials, according to Wikipedia. Iran responded by closing the Strait of Hormuz, through which roughly a quarter of global seaborne oil trade passed before the conflict, the same source said. After the Islamabad talks collapsed in April, the US announced the blockade to stop ships entering or leaving Iranian waters, though US Central Command said it would target vessels specifically bound for or departing from Iranian ports.

Three senior Iranian sources told Reuters, as reported by Iran International, that the US pressure campaign was becoming very difficult for Iran to withstand. The United Arab Emirates suspended trade with Iran in August 2026 amid the war, Iran International reported, further narrowing Tehran's remaining trade and payment channels.
