How the Latest Iran Sanctions Could Impact Central Asia

National Interest | James D. Durso

United States secondary sanctions under Treasury Secretary Scott Bessent’s newly launched Operation Economic Outcast threaten to disrupt critical trade, energy, and transport corridors linking landlocked Central Asian republics to global markets through Iran, forcing regional banks to halt legitimate transactions to avoid losing access to the American financial system.

This economic pressure directly undermines regional efforts to diversify transit routes away from Russia and China. Central Asian states rely heavily on Iranian infrastructure, including the International North-South Transport Corridor and ports like Bandar Abbas, to secure southern maritime access. Kazakhstan faces delays to its logistics terminal at Bandar Abbas despite a 26.4 percent trade increase in 2025, while Uzbekistan risks losing up to $1.5 billion due to transport disruptions. Regional energy security remains highly vulnerable. Consequently, these measures may inadvertently drive Central Asian nations closer to Moscow and Beijing, contradicting Washington's broader strategic goals of fostering regional independence.

Comment

Washington's implementation of Operation Economic Outcast creates a direct policy friction with its own C5+1 diplomatic framework in Central Asia. By threatening secondary sanctions against financial institutions processing transactions via the International North-South Transport Corridor, the US Treasury Department inadvertently penalises the landlocked republics it seeks to insulate from Moscow. This financial pressure forces regional banks in Astana and Tashkent to over-comply, systematically dismantling the very non-Russian trade routes the United States has spent years promoting.

The resulting commercial paralysis will likely accelerate Central Asian integration into Beijing's Belt and Road Initiative infrastructure. Deprived of viable southern maritime access through the Iranian port of Bandar Abbas, Kazakhstan and Uzbekistan have little choice but to deepen their reliance on the China-Kyrgyzstan-Uzbekistan Railway. Ultimately, the aggressive enforcement of Operation Economic Outcast risks consolidating China's economic hegemony over the Eurasian heartland at the expense of the US-Uzbekistan critical-minerals partnership.

Strategic Question for Discussion

If the enforcement of Operation Economic Outcast permanently disrupts transit along the International North-South Transport Corridor, how can Central Asian states balance their compliance with Washington against their structural need for southern maritime access?

The available evidence points toward a dual-track strategy where Central Asian capitals nominally comply with US Treasury mandates while quietly expanding barter trade and non-dollar clearing systems. However, prolonged disruption to the International North-South Transport Corridor will likely force these states to accept higher transit costs along the Trans-Caspian route or increase their infrastructural dependence on Chinese-backed alternatives. My assessment is that this friction will ultimately erode the efficacy of Western diplomatic engagement in the region as economic survival overrides sanctions compliance.
