Iran war exposes fragility of Gulf-Asia supply chains

Since the Iran war began late last month, it has threatened shipping across the Middle East’s two most important maritime chokepoints – the Strait of Hormuz and the Bab el-Mandeb – through which much of Asia’s energy imports and manufactured exports flow.For Gulf States and their major trading partners in Asia, the conflict is forcing a hard question: what, if anything, can protect supply chains if US security guarantees can no longer be taken for granted?Analysts say the usual answers – stockpiles, alternative transport corridors or new security arrangements – offer only limited protection against the kind of disruption now unfolding, which could persist even after the war ends.The vulnerability is not new.

Instead, the prevailing assumption was that the US, through its vast network of military bases across the region, would prevent a belligerent nation such as Iran from imposing a stranglehold on trade passing through Hormuz.
