In the early hours of August 19, 2026, the UAE Ministry of Foreign Affairs announced the suspension of all trade, commercial, and financial transactions with Iran, with the resumption date to be announced later.
This decision was directly triggered by a military incident on August 18. The UAE Ministry of Defense stated that its air defense system detected two ballistic missiles launched from Iran, one landing outside UAE territorial waters and the other inside. The Ministry of Defense immediately declared a state of high alert.
Iran refuted the allegations, calling them "baseless" and contrary to the principle of good neighborliness. It is noteworthy that this was not an isolated incident. Earlier this month, the UAE accused Iran of attacking Abu Dhabi National Oil Company vessels operating in the Strait of Hormuz. Since the outbreak of the US-Iran conflict in February, Iran's military retaliations have repeatedly targeted Gulf states, with the UAE adopting the strongest stance.
The UAE is Iran's largest source of imports. Statistics show that nearly one-third of Iran's annual imports are transshipped through the UAE. Dubai is not only a distribution center for goods but also a crucial "window" for Iran to circumvent international sanctions and conduct cross-border financial transactions. Former U.S. Assistant Secretary of State and retired Brigadier General Mark Kimmet, in an interview with Al Jazeera, stated bluntly that the economic impact of the UAE's move on Iran may be more significant than the long-term U.S. sanctions.
Once the Dubai passage is closed, Iran will face: supply chain disruption risk (nearly one-third of its import routes will be cut off); foreign exchange circulation disruption (loss of its most important cross-border financial channel); and shortages of goods and inflationary pressures (directly impacting the Iranian domestic market). Some have compared this move to the U.S. embargo imposed on Japan in 1941 on the eve of World War II-the Iranian government is highly likely to interpret this as a "quasi-war act."
Data shows that before the outbreak of war, an average of about 110 ships passed through the Strait of Hormuz daily; in the past 24 hours, only 3 commercial vessels passed through. On a weekend in mid-August, the data was even more alarming: only 5 commodity ships passed through the strait on Saturday, and no vessels were detected passing through on Sunday.
Meanwhile, data from the ship tracking agency Kpler shows that more than 80% of ships transiting the Strait of Hormuz chose the "Oman route" (southern route) rather than the Iranian-controlled northern route. This means that Iran's actual control over the waterway is weakening, but the shipping risks have not decreased-the continued attacks on ships and oil flows far below pre-war levels speak for themselves.
During this round of the US-Iran war, Iranian missiles and drones struck multiple US-related targets within the UAE, including military bases, energy facilities, and financial centers. The economic costs are already evident: in the first quarter of this year, Dubai hotel occupancy rates fell by about 40%, tourism revenue losses exceeded $5 billion, and foreign direct investment decreased by one-third year-on-year. The United Nations predicts that if the war continues, the UAE's GDP could shrink by about 5%. The UAE's recent "business cut-off" is both a strong signal to Iran and a demonstration to international investors of its "open and safe business environment." However, this precisely illustrates that the regional security situation has seriously threatened its business ecosystem.
