CRA Releases Supplemental Brief on Iran Conflict Supply Chain Implications
The conflict involving Iran is reshaping global supply chains in real time — and the full scope of its impacts is still unfolding.
March 10, 2026 the CRA released a supplemental brief to its monthly Supply Chain Brief examining how this rapidly evolving situation is affecting the movement of critical goods, commodities, and materials that communities, businesses, and essential services depend on. This supplemental brief is designed to give planners, operators, and decision-makers some insights into both what’s happening now and what to watch for ahead.

What’s at Stake
Some impacts are already visible: energy prices are surging, major shipping carriers have suspended operations across the Persian Gulf, and maritime insurance costs have spiked for vessels transiting the region. But supply chain disruptions rarely stop there. Secondary and tertiary effects — on agriculture, healthcare, water treatment, and manufacturing — often take longer to surface, and can be harder to anticipate.
This brief addresses several dimensions of the supply chain landscape:
-
- Energy production and export dynamics in the Persian Gulf region
- The strategic role of the Strait of Hormuz as a global chokepoint
- Price movements in crude oil and natural gas markets
- Implications for sectors that rely on commodities originating from or transiting through the region, including agriculture, healthcare, and water treatment
- California’s specific fuel supply vulnerabilities given recent refinery closures
- Maritime shipping disruptions, surcharges, and insurance market changes
What Makes This Moment Different
Supply chains are simultaneously resilient and fragile. Many commodities can be rerouted or substituted over time. But some resources — tied to specific geographies, specialized infrastructure, or limited production capacity — cannot be easily replaced. And when disruptions occur under conditions of uncertainty, human behavior amplifies the impact: precautionary purchasing and hoarding can intensify shortages that might otherwise have remained manageable.
This conflict is also not occurring in isolation. As the market adapts, new trade patterns will emerge, but those adaptations may simply shift vulnerabilities to new locations.
Read the Briefs
Every month the CRA compiles a Supply Chain Brief looking at fuel, energy, water, food/ag, and pharmaceutical supply chains as well as various transportation modes through the eyes of emergency and business continuity managers. The Supply Chain Brief – Iran Conflict Supplemental provides a snapshot of current and potential supply chain impacts associated with the Iran conflict. The situation remains highly dynamic, and this document does not capture all possible effects as conditions continue to evolve.
