Escalating conflict between Iran and international forces, combined with renewed instability in Afghanistan, threatens to sever critical trade arteries connecting landlocked Central Asian states to global markets, jeopardizing billions of dollars in infrastructure investment and regional economic development.
The Trans-Afghan Railway, a $6 billion project designed to link Central Asia to the Arabian Sea and reduce transit time by five days, faces mounting uncertainty as security deteriorates along the 760-kilometer planned route. Similarly, the TAPI pipeline—a 1,814-kilometer natural gas artery from Turkmenistan through Afghanistan and Pakistan to India—and the $1.2 billion CASA-1000 electricity transmission project remain stalled as regional tensions escalate.
"The corridors are effectively closed," according to recent analysis of Pakistan-Afghanistan trade flows, which totaled $2.4 billion in 2025 but now face severe disruption. Border closures have stranded cargo, vehicles, and drivers, while shipping and insurance costs surge amid the deteriorating security environment.
The conflict's ripple effects extend beyond bilateral trade. U.S. and Israeli military operations targeting Iran have disrupted the Strait of Hormuz, which handles 20 percent of global oil and liquefied natural gas exports. Airspace closures affect thousands of flights, while attacks on Iranian port infrastructure at Chabahar and Bandar Abbas threaten Central Asia's alternative maritime access routes.
For landlocked states including Kazakhstan, Uzbekistan, Kyrgyzstan, , and , these disruptions eliminate critical alternatives to Russian-controlled northern routes or Chinese-dominated eastern corridors. The instability forces regional economies into greater dependence on powers whose interests may not align with Central Asian sovereignty.
