Central Asia's five landlocked republics are diversifying away from Iranian transit routes without abandoning them, after the 2026 conflict disrupted rail links, Caspian shipping and the International North–South Transport Corridor. An Oilprice.com analysis argues that ties with an IRGC-dominated Tehran will likely stay pragmatic and transactional, driven by trade and connectivity rather than ideology.
Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan still need Iran as a southern outlet, and the war may encourage them to restore Iranian routes as quickly as possible and invest in making them more resilient. Iran offers the region the shortest route to the Indian Ocean, through the ports of Bandar Abbas and Chabahar.
The 2026 war disrupted the corridors
Iran banned food exports in March 2026, hitting importers such as Tajikistan. Strait of Hormuz tensions and wider instability raised costs and halted some trade flows, and rail links, Caspian shipping and the INSTC were all disrupted.
Central Asian governments mostly held to official neutrality and called for restraint, with no unified position. Tajikistan, Turkmenistan and Uzbekistan sent humanitarian aid to Iran, and none aligned against it, but diversification accelerated.
Washington is also prepared to attack the infrastructure the republics will use for trade. In July the U.S. attacked the Aq Tekeh Khan railway bridge in Iran's Golestan Province, part of a strategic rail corridor linking China, Turkmenistan and Iran. The U.S. also struck Iran's Chabahar port, damaged the maritime traffic control tower and bombed bridges around Bandar Abbas port.
Trade was rising before the war
Commerce had been growing on economics rather than ideology. Tajikistan's trade with Iran quadrupled in recent years, reaching hundreds of millions, while Kazakhstan targeted $3 billion turnover, mostly agricultural products.
Turkmenistan focused on gas swaps and pipelines, and Uzbekistan saw investment roadmaps and port deals. Physical geography gives Ashgabat weight here: Turkmenistan shares an 1,100 km border with Iran and is the principal overland connection between Iran and Central Asia.
A Eurasian Economic Union–Iran free trade agreement took effect in May 2025, with potential to dramatically expand trade volumes.
What the next two years may look like
Trade and transit volumes may remain suppressed or diverted over the next one to two years as the republics accelerate diversification toward alternative corridors and closer engagement with Turkey or the West. Even so, the analysis expects them to keep their Iranian connectivity options rather than drop them.
Assuming an end to hostilities, cooperation has strong rebound potential. Post-war reconstruction could let Central Asian states supply grain, construction materials, metals, engineering services, electricity and logistics to a market of 93 million people, and the extent of that recovery will depend heavily on sanctions policy and investor confidence. Economic pragmatism will likely persist because the IRGC benefits from stable revenue, local markets and quiet borders.
