Iran Threatens 'Earthquake-Like' Retaliation as UAE Cuts Trade Ties and US Prepares Sweeping Sanctions
Iran vowed on August 24, 2026 to retaliate against any country cooperating with a forthcoming US sanctions package, threatening an 'earthquake-like' response if Washington proceeds with the measures. The warning came from security chief Mohsen Rezaei as the United Arab Emirates — Iran's largest Middle East trading partner — confirmed it was ending all commercial and financial transactions with Tehran. US Treasury Secretary Scott Bessent described the planned sanctions as 'the single greatest financial offensive ever marshalled against an adversary,' with the US announcing secondary sanctions on any country or entity trading with Iran The Guardian.
Secondary sanctions are a powerful tool: rather than just penalizing Iran directly, they punish third parties — companies, banks, or entire nations — that continue doing business with Tehran. The effect is to make Iran a financial pariah even for countries that have no dispute with it.
The UAE's decision formalized a suspension first announced on August 19, 2026, when its Ministry of Foreign Affairs declared all trade halted until further notice. On August 18, the UAE's Director of Strategic Communications confirmed the cessation of trade, commercial exchanges, and financial transactions with Iran WAM. Analyst Kimmitt noted that the UAE embargo could damage Iran's economy more severely than any US sanctions imposed to date Al Jazeera.
The rupture between the two Gulf neighbors follows months of direct conflict. During the 2026 war, the UAE absorbed 2,800 incoming systems from Iran, including 2,256 drones and 563 missiles, after Tehran retaliated against a joint US-Israeli attack Institute for the Study of War. On August 14, the Arab League condemned Iran's targeting of two UAE-operated tankers transiting the Strait of Hormuz, which the UAE had earlier blamed on Tehran AP WAM. UAE officials had also raised alarm over Iran's disruption of maritime routes at the BRICS Trade Ministers Meeting on August 8 and welcomed an FAO condemnation of Iran's disruption to global food supply chains in May WAM WAM.
Rezaei warned Iran's Gulf neighbors against joining the US campaign, stating that if surrounding countries joined the Americans in their economic war, 'not a drop of oil would leave the Persian Gulf and the Strait of Hormuz' The Guardian. Iran had already made dramatic demands around the Strait on August 8, including compensation for war damage, the lifting of sanctions, and the unconditional release of frozen assets AP. Foreign Minister Abbas Araghchi dismissed the expected US sanctions as a sign of American weakness The Guardian.
The economic pressure on Tehran is acute. Iran's central bank governor Abdolnaser Hemmati admitted that crude exports had 'virtually stopped' due to a US naval blockade of Iranian ports The Guardian. The Iranian rial traded at 1.992 million per dollar on the unregulated market on August 24, down 4.5% since the US president announced a 'crushing economic operation' against Tehran The Guardian.
The Treasury's latest offensive builds on sustained targeting of Iran's illicit networks throughout 2026. In late July, OFAC — the Treasury's sanctions enforcement arm — sanctioned over 100 vessels linked to Iran's shadow fleet (a network of tankers used to sell oil covertly) in an action targeting an illicit maritime insurance scheme US Treasury. An August 7 action against Iran's global clandestine shadow banking apparatus marked the eighth such measure that year US Treasury. Earlier actions targeted weapons procurement networks on July 15 and UAV procurement networks tied to Mahan Air on April 21 US Treasury US Treasury.
The broader context here involves a deliberate US strategy to collapse Iran's economic lifelines through two combined levers: extraterritorial sanctions enforcement and military interdiction. The naval blockade has achieved what sanctions alone could not — a near-total halt in crude exports. With the UAE now acting as a willing participant rather than a neutral conduit, the secondary sanctions threat has effectively weaponized Gulf commercial self-interest. For Tehran, the loss of its primary regional trade partner compounds the operational impact of the shadow fleet sanctions, closing both overt and covert export channels simultaneously.
Yet Rezaei's threat to close the Strait of Hormuz carries weight beyond typical deterrence rhetoric. The Strait is a narrow chokepoint through which roughly one-fifth of the world's oil supply passes. With Iran's own exports already stopped, the asymmetrical calculus of shutting the waterway shifts: Iran has less to lose economically from a closure than it normally would. Iran has targeted commercial shipping throughout 2026, seizing a ship off the UAE coast in May and attacking vessels near Oman AP. The question now is whether Tehran views economic strangulation as an existential enough threat to risk the military confrontation that a full Strait closure would provoke.
Iran's historical framing of its sanctions posture remains consistent with its diplomatic messaging. The foreign ministry has noted that UN sanctions against Iran terminated on September 19, 2025, positioning current US measures as unilateral rather than internationally sanctioned Iranian MFA. Iran's embassy in Beijing has stated that US sanctions prevent Iranian access to humanitarian goods including medicines and medical equipment Iranian Embassy Beijing. Acting Foreign Minister Hossein Amirabdollahian previously framed Iran's military responses as legitimate self-defense following Israeli strikes on the Iranian Embassy in Damascus Iranian MFA.
