2026 Iran War: 2026-09-21

Iran's Statistical Center reported GDP contracted 10.1% year-on-year from March 21 to June 20, covering the opening months of the US-Israel war. Crude oil and natural gas activity fell 26.4%, while GDP excluding oil declined 4.6%. Al Jazeera cited tanker data showing Iranian crude loadings dropped from about 2 million bpd in March to roughly 220,000-255,000 bpd in August under the US naval blockade.

Major-General Amir Hatami, Iran's army commander, said Iranian forces are fully prepared, vigilant and ready to face any renewed attack by the United States or Israel. The statement comes as Tehran's central command claims it has intelligence that Washington is preparing to resume strikes, while Trump says he remains in deciding mode on further military action, pressure or a deal.

Treasury Secretary Scott Bessent told CNBC that on September 23 Iranian airlines will be shut down around the world under secondary sanctions. He said airports, fuel suppliers and ticketing firms that service Iranian carriers risk being cut off from the US dollar system. The step follows earlier Treasury sanctions on remaining Iranian airlines and aviation support companies.

Iran's Khatam al-Anbiya Central Headquarters said Sunday it has intelligence that the United States is preparing to resume hostile actions against Iran. The command warned that any renewed US attack would bring continuous strikes on American bases and interests in the region, and said regional states that help Washington would be treated as complicit. Al Jazeera reported the statement as fighting has been lower for months after a 60-day memorandum expired last month.

President Trump told Fox News he is in a deciding mode on Iran, listing further military action, economic pressure, or a deal as options. He said he would be open to meeting Iranian President Masoud Pezeshkian on the sidelines of the UN General Assembly in New York this week. Iran's Foreign Minister Abbas Araghchi left for New York with a brief Qatar stopover as Doha continues mediation.

Middle East Spectator cited the New York Times saying President Trump cancelled planned US airstrikes against Houthi targets in Yemen shortly before they were to begin. The package followed an appeal from Saudi Crown Prince Mohammed bin Salman, but most of Trump's inner circle opposed opening another Middle East front, citing energy insecurity and overextension.

At a UNGA-adjacent event in New York, Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani said the economic and security fallout from the US-Israeli war on Iran was an "earthquake" with shock waves beyond the Middle East. He called for a regional framework in which sovereignty is respected and no state permanently threatens another. Qatar's Foreign Ministry spokesman separately said Doha mediators continue efforts to restart Iran-US talks.
