Treasury Sanctions Iran's Auto, Rail and Steel Sectors.

Treasury Secretary Scott Bessent announced new sanctions Thursday against Iranian automotive, railway, and steel companies. The move is part of Operation Economic Outcast, an ongoing campaign to restrict Iranian government revenue.

• Two car companies — Iran Khodro and SAIPA — represent over 90% of Iran's domestic auto market.
• 125 commercial vessels have been redirected by U.S. forces as of Sept. 30.
• Hong Kong-based Ramin Keshvardoust facilitated Iranian steel and oil shipments totaling tens of millions of dollars.
• Iran's rial hit a new record low against the dollar earlier this week.

Why it matters: Treasury describes Iran's automotive sector as its largest economic sector outside oil and gas and a major revenue source for the government.

• The railway system was sanctioned on allegations it has been used to transport oil via land routes to bypass the U.S. naval blockade.
• Previous sanctions rounds have already covered aviation, shipping, technology, digital assets, gold, and petroleum.

What’s next: The U.S. Navy resumed its blockade of Iranian ports in mid-July after a prior pause collapsed.

• Treasury says today's action lays groundwork for partners to further cut the regime's revenue.
• Whether successive sanctions rounds and the naval blockade will prompt Iran to return to negotiations or escalate the conflict remains unresolved.
• How Iran's trading partners — including UAE- and Hong Kong-based intermediaries — respond to the new designations is unclear.
