Overview
The disruption of maritime shipping transiting through the Strait of Hormuz and surrounding seas can feel remote to business leaders in Wisconsin until it shows up in shipment delays, rising operating expenses, and increased fuel costs. 
This is precisely what is happening now as escalating conflict between the U.S., Israel, and Iran are disrupting one of the world’s most critical shipping corridors.
The businesses that prepare now for rising costs and supply chain disruptions tied to instability will be better able to manage uncertainty, protect margins, and maintain operational continuity.
Why Shipping Disruption Matters
The Strait of Hormuz serves as a passage for global markets, carrying approximately one-fifth of global petroleum liquids, along with substantial volumes of liquefied natural gas, fertilizers, helium, food, and other essential products. In fact, tanker traffic, which initially plunged roughly 70-percent in the days following the initial attack, has since fallen to near zero. With only limited traffic allowed to pass through, many companies that do business in and with the region have declared force majeure on shipments, signaling delays or an inability to meet existing contractual obligations.
From a supply chain standpoint, the most immediate impact has been constrained energy supply coupled with price volatility. Oil and gas markets typically respond quickly to perceived risk in the region, increasing input costs for manufacturers, logistics providers, and energy-intensive industries. For businesses, this environment has led to margin pressure, rising operating expenses, and, in some cases, the need to adjust pricing strategies to offset higher costs. In fact, the closure has already pushed oil prices over $100 per barrel, with many analysts warning that a prolonged conflict could drive oil prices even higher and up to $200 per barrel. Similarly, the export of natural gas from the region has decreased significantly.
Logistics networks have also been impacted. The downstream effects extend across multiple sectors. Notably, energy-intensive industries such as chemicals, agriculture, and advanced manufacturing inputs sourced from this region have faced compounding cost pressures, while consumer goods companies have also faced increases in packaging, transportation, and raw material expenses, requiring more disciplined cost management and pricing decisions. Companies operating lean or just-in-time inventory models have been particularly exposed, as delays have created bottlenecks, disrupted production schedules, highlighting vulnerabilities in their supplier networks.
How Business Leaders Can Respond
Understand the Extent of Exposure
The first responsibility of business leaders during a Strait of Hormuz disruption is to understand the extent of their organization’s exposure. Many companies mistakenly assume that they are insulated from this geopolitical event because they do not directly import products from the Middle East. In reality, the global economy is highly interconnected. Manufacturers in Asia, Europe, and North America often rely on energy, raw materials, chemicals, and transportation networks that are directly affected by developments in the Gulf region. Consequently, a closure of the Strait of Hormuz will have cascading effects across multiple industries, increasing production costs, extending delivery times, and creating shortages of critical inputs. Business leaders must therefore conduct a thorough assessment of their supply chains to identify direct suppliers and second- and third-tier suppliers whose operations may be vulnerable to energy price spikes or transportation disruptions.
Evaluate Inventory Management Strategies
Secondly, leaders should evaluate their inventory management strategies. As stated earlier, for decades, many businesses have embraced just-in-time inventory models to minimize storage costs and maximize efficiency. While effective under stable conditions, these models can leave companies vulnerable when supply chains are disrupted. A closure of the Strait of Hormuz delays shipment, reduce the availability of critical materials and create significant bottlenecks in transportation networks. Maintaining strategic reserves of essential products, components, and raw materials may increase short-term carrying costs, but such investments can prove invaluable during periods of uncertainty. Businesses that possess sufficient inventory to continue operations while competitors face shortages may gain a significant market advantage.
Diversify Suppliers and Transportation Methods
Diversification is another critical component of an effective response strategy. Organizations that depend heavily on a single supplier, region, or transportation corridor expose themselves to concentrated risk. Business leaders should identify alternative suppliers in different geographic locations and develop contingency sourcing plans before a crisis occurs. Establishing relationships with multiple suppliers can improve flexibility and reduce dependence on any one source of supply. Similarly, companies should explore alternative transportation methods and routes, including rail, air freight, and alternative maritime pathways where feasible. While these alternatives may involve higher costs, they can provide essential continuity when traditional supply routes become unavailable.
Review Legal Obligations
Business leaders should also pay close attention to contractual obligations and legal considerations. Supply chain disruptions often raise questions regarding delivery commitments, force majeure provisions, pricing adjustments, and performance obligations. Organizations should review key contracts to understand their rights and responsibilities in the event of significant disruptions. Legal and compliance teams should work closely with operational leaders to identify potential areas of exposure and develop strategies to manage contractual risk. In addition, companies engaged in international trade should closely monitor developments related to sanctions, export controls, customs requirements, and other regulatory measures that governments may implement in response to escalating geopolitical tensions.
Key Takeaways for Wisconsin Businesses
The disruption in the Strait of Hormuz is not merely a regional issue, it represents a systemic supply chain risk, requiring a proactive risk management strategy. This includes scenario planning, supplier diversification, strategic inventory buffering, and ongoing monitoring of geopolitical developments. Organizations that take a forward-looking approach will be better positioned to manage uncertainty, protect margins, and maintain operational continuity.
