Descartes Global Shipping Report: U.S. Imports from Hormuz-Affected Ports Collapse in May 2026
The global shipping industry is no stranger to disruption, but the latest data from Descartes Systems Group paints a striking picture of just how severely the Strait of Hormuz closure has impacted U.S. maritime trade. According to a special June edition of the Descartes Global Shipping Report, total U.S. imports departing from Hormuz-affected ports plummeted by an extraordinary 93.2% year over year in May 2026 — a decline that has sent shockwaves through supply chain planning, commodity markets, and logistics strategy worldwide.
What the Data Shows: A Historic Drop in Import Volumes
To understand the magnitude of this disruption, the numbers speak for themselves. In May 2025, U.S. imports departing from Hormuz-affected ports stood at approximately 1.5 million metric tons. By May 2026, that figure had collapsed to just 100,591 metric tons — a reduction of more than 1.4 million metric tons in a single year. This is not a minor fluctuation; it represents the near-total disappearance of a key corridor of global maritime commerce.
Descartes, recognized globally as a leader in uniting logistics-intensive businesses in commerce, released this special report to help shippers, importers, and supply chain professionals understand both the scale and the trajectory of this disruption. The data makes clear that the impact is not only severe but potentially structural in nature, with early warning signs visible months before the full effects materialized in official import statistics.
Early Warning Signs Were Already Emerging
One of the most important findings in the report is that the collapse seen in May 2026 did not arrive without precursors. Between May 2025 and February 2026, year-over-year changes in import volumes from Hormuz-affected ports fluctuated within a relatively normal range — declining as much as 27.7% in some months and growing as much as 26.2% in others. These swings, while notable, were broadly in line with historical patterns of global trade variability.
However, March 2026 showed a year-over-year decline of 33.0%, and April 2026 deepened that trend with a 34.7% decline. These back-to-back months of accelerating decline suggest that shipping flows through or from Hormuz-adjacent regions were already weakening significantly before the full impact of any formal closure appeared in the May data. For supply chain professionals, this underscores the critical importance of continuous monitoring of leading indicators — not just lagging trade statistics — to anticipate and respond to geopolitical disruptions before they reach crisis levels.
Why the Strait of Hormuz Matters to Global Trade
The Strait of Hormuz is one of the most strategically vital maritime chokepoints in the world. Connecting the Persian Gulf to the Gulf of Oman and the broader Arabian Sea, it serves as the primary export route for crude oil and liquefied natural gas from major producers including Saudi Arabia, the United Arab Emirates, Iran, Iraq, Kuwait, and Qatar. Roughly 20% of the world's traded oil passes through this narrow waterway on any given day.
For the United States, imports transiting through or originating from Hormuz-affected ports span a range of critical commodities, including:
- Crude oil and petroleum products, which feed directly into domestic energy production and refining capacity
- Petrochemical feedstocks used across manufacturing and plastics industries
- Specialty chemicals and industrial materials sourced from Gulf state producers
- Fertilizers and agricultural inputs derived from natural gas processing in the region
When flows through this corridor are disrupted — whether by conflict, sanctions, or deliberate closure — the ripple effects extend far beyond the energy sector. Manufacturing costs rise, freight rates spike on alternative lanes, and supply chains that depend on just-in-time delivery face immediate and painful bottlenecks.
Implications for U.S. Importers and Supply Chain Planners
The 93.2% collapse in import volumes is not simply a statistical anomaly — it has real, tangible consequences for businesses across the United States. Companies that source raw materials, energy inputs, or finished goods from the Gulf region are now facing an urgent need to diversify their supplier base, explore alternative sourcing geographies, and re-evaluate their inventory buffers and safety stock policies.
Logistics teams are also grappling with sharply higher freight costs as cargo that once moved efficiently through the Hormuz corridor is now being rerouted through longer, more expensive lanes. The Cape of Good Hope route around southern Africa, for example, adds significant transit time and fuel costs for vessels seeking to bypass the Persian Gulf entirely. These increases inevitably find their way into landed costs and, ultimately, consumer prices.
For procurement leaders, the Descartes report serves as a timely reminder of the need to build geopolitical risk assessments into sourcing strategy — not as a theoretical exercise, but as an operational discipline that informs contracts, inventory levels, and supplier diversification plans.
The Role of Data and Analytics in Navigating Disruption
One of the broader takeaways from the Descartes Global Shipping Report is the value of granular, real-time trade data in helping businesses respond to fast-moving global events. By analyzing bill-of-lading data and port-level import statistics, Descartes is able to identify disruption trends as they emerge rather than after the fact — a capability that is increasingly essential in a world where geopolitical flashpoints can materialize with little warning.
The ability to track not just aggregate trade volumes but specific origin ports, commodity types, and shipping lanes gives logistics professionals a far more precise view of where their supply chains are exposed. In the context of the Hormuz disruption, this kind of visibility is the difference between reacting to a crisis and preparing for one.
Looking Ahead: What Comes Next for Hormuz-Affected Trade Flows
The trajectory of U.S. imports from Hormuz-affected ports will depend heavily on developments in the region. If the disruption proves temporary, some degree of recovery in import volumes could be expected in subsequent months, though backlogs, renegotiated contracts, and shifted trade patterns may delay a full return to prior levels. If the disruption proves prolonged, companies will need to accelerate structural adjustments to their supply chains — including locking in alternative supply arrangements and absorbing higher logistics costs as a new baseline.
Descartes has committed to continued monitoring of this situation through its monthly Global Shipping Reports, providing the logistics community with the data and analysis needed to navigate an increasingly complex and unpredictable global trade environment. For supply chain professionals, staying closely attuned to these reports will be a key part of managing risk in the months ahead.
Conclusion
The 93.2% year-over-year collapse in U.S. imports from Hormuz-affected ports in May 2026 is one of the most dramatic single-corridor trade disruptions recorded in recent history. The Descartes Global Shipping Report provides an authoritative and data-driven lens through which to understand both the scale of the impact and the early warning signals that preceded it. For importers, logistics providers, and supply chain planners, the message is clear: geopolitical risk monitoring, supplier diversification, and proactive data analysis are no longer optional — they are essential pillars of resilient supply chain management in the current global environment.
