Iran war supply chains are showing a strange split: markets are calm, but the underlying logistics picture is getting tighter. The Guardian warned on May 10 that governments and businesses may be displaying a dangerous degree of complacency.
The risk is not only crude oil. The report pointed to pressure in fuel, aluminium, industrial chemicals, lower-tier suppliers and transport networks that can turn inventory drawdowns into production problems.
What happened
The closure and disruption around Hormuz forced companies to rely on stockpiles, alternate routes and emergency planning. Asia has moved closer to rationing, while Europe has remained more measured but increasingly exposed.
Why it matters
Supply-chain shocks create margin risk before they become visible in consumer data. If raw materials and fuels stay tight, companies can face higher input costs, lower output and harder guidance conversations.
Market impact
The first market reaction has been energy prices and inflation expectations. The second-order reaction could appear in industrials, transport, chemicals, autos and consumer-goods companies if shortages interrupt production.
