Kazakhstan's new terminal at Iran's Shahid Rajaee Port faces renewed military and sanctions risks after U.S. strikes and a new sanctions campaign. The 27-year BOT agreement signed June 28 aims to open Gulf and Indian Ocean markets, but the route's viability is now uncertain.
Key Facts
- Kazakhstan and Iran signed a 27-year build-operate-transfer agreement on June 28 for a Kazakh terminal at Shahid Rajaee Port in Bandar Abbas.
- U.S. strikes in July damaged the Aq Taqeh Khan bridge on a rail route connecting Iran with Turkmenistan and Kazakhstan.
- On August 24, U.S. Treasury Secretary Scott Bessent launched Operation Economic Outcast, expanding secondary sanctions to digital assets, technology, gold, aviation, and shipping.
- Kazakhstan-Iran trade rose 26.4% in 2025 to $430.2 million, and rail traffic between the two countries increased 69%.
- Freight traffic along the International North-South Transport Corridor reached 3.5 million tons.
The Iranian Route
Iran provides Central Asia with one of the few overland routes to the Persian Gulf and the Indian Ocean. From Bandar Abbas and Chabahar, cargo can move onward toward India, the Gulf states, and East Africa. Iran also offers a western overland route toward Turkey. Unlike the Middle Corridor, which requires switching between rail and maritime transport across the Caspian Sea, the Iranian route allows a continuous overland chain.
Military and Sanctions Pressure
In July, U.S. strikes hit Iranian railway and coastal infrastructure, damaging the Aq Taqeh Khan bridge on a route linking Iran with Turkmenistan and Kazakhstan. No confirmed halt to Central Asian freight traffic was reported, but military risk became a concrete concern for carriers. On August 24, U.S. Treasury Secretary Scott Bessent announced Operation Economic Outcast, combining direct sanctions with pressure on Iran's foreign economic partners. The United States said it would set timelines for other countries to shut down economic activity with Iran and expanded secondary sanctions to cover digital assets, technology, gold, aviation, and shipping. Nearly 60 Iran-linked individuals, entities, and vessels were sanctioned, though Washington has not publicly identified which countries could face penalties first.
Kazakhstan's Expanding Exposure
Kazakhstan's trade with Iran increased 26.4% in 2025 to $430.2 million. Freight traffic along the International North-South Transport Corridor reached 3.5 million tons. Rail traffic between Kazakhstan and Iran rose 69%. The expanding transport network is now exposed to greater military and sanctions risks.
