The Potential Impacts of the War in Iran on U.S. Transportation Infrastructure

Introduction

When geopolitical fires ignite in the Persian Gulf, it is easy to assume the fallout lands squarely on oil executives and defense contractors. Think again. The ripple effects could reach deep into the America we all love and into the brown trucks or sorting hubs we all know so well. UPS, is the world's largest package delivery company and one of the most significant employers of International Association of Machinists and Aerospace Workers (IAM) members in the country. Which means this war will affect you.

Fuel Costs: The Hidden Cargo

UPS operates one of the largest private airline fleets on earth, and jet fuel is its single largest operating expense. The Strait of Hormuz — that narrow chokepoint through which roughly 20% of the world's oil supply flows — sits squarely in Iran's backyard. Any escalation that disrupts tanker traffic there translates almost immediately into spiking fuel surcharges, compressed margins, and budget pressure that companies like UPS routinely attempt to pass downstream.

For IAM-represented mechanics, technicians, and fleet workers, fuel volatility is not an abstract macroeconomic concern. It is the difference between a company investing in its workforce and a company hunting for concessions at the bargaining table.

Supply Chain Turbulence Hits the Hub

UPS's business model depends on the reliable, high-volume movement of goods. Many of which originate in Asia and outside of the U.S. so conflict-driven shipping disruptions, rerouted cargo vessels, and strained port capacity create backlogs that cascade through every link in the logistics chain. When freight volumes become unpredictable, UPS faces pressure to adjust staffing levels, delay capital investments, and restructure routes. These decisions will directly affect IAM-represented workers whose job security is tied to those operational choices.

The IAM has long understood that a strong contract is only as durable as the economic environment surrounding it. Geopolitical shocks are precisely the kind of external pressure that can erode hard-won gains.

Security Costs and Cyber Risk

Heightened military tensions in the Persian Gulf typically prompt elevated security protocols at major U.S. airports and cargo facilities. Increased compliance costs and the ever-present threat of conflict-linked cyberattacks on logistics management systems represent operational risks that UPS, and by extension its workforce, cannot afford to dismiss.

The IAM (you and me) have a vested interest in pushing for robust cybersecurity infrastructure at UPS facilities. A successful attack on cargo management systems does not just inconvenience executives it would idle hourly workers which could mean smaller paychecks. So if you SEE something SAY something.

The Bigger Picture for IAM

Middle East instability is a reminder that the labor movement cannot operate in isolation from global events. The IAM's strength at UPS is built on contracts, solidarity, and good strategy; sustaining that leverage requires anticipating the economic forces that management will inevitably cite during negotiations.
