U.S. Treasury Sanctions Indian and Turkish Firms Over Alleged Support for Iran

The U.S. Treasury Department issued new sanctions on November 4, 2026, against companies and individuals based in India and Turkey. The measures form part of Operation Economic Outcast, the administration's effort to limit Iran's ability to sell oil and fund its operations during the conflict involving the United States and Israel. Treasury officials said the designated parties had provided support that helped Iran move or sell oil outside authorized channels.

The sanctions freeze any assets the named entities hold under U.S. jurisdiction and prohibit U.S. persons from dealing with them. Secondary sanctions can also deter banks and companies in third countries from continuing business with the targets. India and Turkey have both maintained trade links with Iran in the past. The new designations raise the cost of those links for the specific firms named.

The action came one day before the U.S. midterm elections, in which voters gave Democrats control of Congress. Democratic leaders have said they will seek to end the conflict. The sanctions remain in force unless the administration or a future Congress acts to lift them. Iranian oil shipments through the Strait of Hormuz have already faced disruptions, including reports of tankers striking mines or catching fire while using unauthorized routes.

Indian and Turkish authorities have not publicly responded to the specific designations. Companies that appear on the list typically lose access to dollar clearing and face higher insurance and shipping costs. The Treasury has used similar packages in previous rounds to target shipping facilitators, traders and financial intermediaries. The November 4 list adds to that series.

The practical effect for the named Indian and Turkish firms is immediate exclusion from the U.S. financial system and from most dollar-denominated trade. For Iran, the measures form one more layer in the effort to reduce oil revenue while the conflict continues. Whether the new Congress alters the sanctions regime will depend on legislation that has not yet been introduced.
