Iran War Highlights Central Asia’s Vulnerable Southern Trade Corridors
The widening war centered on Iran is reverberating far beyond the Middle East, exposing a structural vulnerability in Central Asia’s economic geography: the region’s reliance on transport corridors that pass through or near Iran and the Persian Gulf. As fighting escalates and shipping risks spread across the region, insurers, shipping companies, and logistics firms are reassessing operations across the Gulf. War-risk insurance premiums have surged while some commercial carriers have scaled back bookings to parts of the region amid growing security concerns. Tensions around the Strait of Hormuz have already pushed shipping costs higher as governments and logistics firms weigh the risks of operating in one of the world’s most important maritime chokepoints. For Central Asia’s landlocked economies, the crisis highlights how much regional connectivity strategies still depend on southern access routes linking the region to global markets. The conflict has also edged closer to the transport routes linking Central Asia with Europe after what were alleged to be Iranian drone strikes on Azerbaijan’s Nakhchivan region, damaging facilities at the exclave’s airport and prompting diplomatic protests from Baku. While the strike did not directly disrupt trade corridors, it underscored how quickly the conflict could spill over into the South Caucasus, a key segment of the Middle Corridor. Nakhchivan is a landlocked Azerbaijani exclave bordering Iran and Turkey, separated from mainland Azerbaijan by Armenia, and lies at the frontier where Iranian territory meets the transport networks of the South Caucasus. The South Caucasus also hosts energy infrastructure with wider geopolitical significance. The Baku–Tbilisi–Ceyhan (BTC) pipeline transports mostly Azerbaijani crude through Georgia to the Turkish Mediterranean port of Ceyhan, from where it is shipped to global markets. In 2025, Azerbaijani oil accounted for 46.4% of Israel’s crude imports, most of it moving through this supply chain before being shipped onward by tanker. The pipeline also carries limited volumes of Kazakh crude - 2-3% of Kazakhstan’s overall exports - making it far more significant for Israel’s energy supply than for Kazakhstan’s export system. Iran’s armed forces have denied responsibility for the drone incident, instead accusing Israel of attempting to provoke tensions and disrupt relations between Muslim countries. The Geography of Connectivity Since independence, Central Asian governments have sought to overcome the constraints of geography. Landlocked and long dependent on Soviet-era transport networks running north through Russia, the region has spent three decades developing alternative corridors in multiple directions. Routes leading south have held particular appeal, offering the shortest overland access to ports on the Persian Gulf and the Indian Ocean. Iran sits at the heart of several connectivity initiatives designed to connect Central Asian rail networks to ports on the Persian Gulf and the Indian Ocean. The Ashgabat Agreement — a multimodal transport framework linking Iran, Oman, Turkmenistan, and Uzbekistan and designed to connect Central Asia with ports on the Persian Gulf and the Gulf of Oman — was created specifically to facilitate international trade and transit between Central Asia and global shipping routes. For countries such as Turkmenistan and Uzbekistan, rail routes...
