The ongoing Iran War has led to severe disruption in shipping through the Strait of Hormuz, a critical maritime chokepoint for global oil and cargo flows, despite a two-week ceasefire agreement between the United States and Iran [1][2][3]. Mitsui O.S.K. Lines, a major Japanese shipping operator, reported that the closure of the strait has forced the company and other industry players to review earnings forecasts, reroute vessels, and undertake a comprehensive review of investment and fleet allocation strategies, resulting in increased costs and logistical complexities [1]. The CEO of Mitsui O.S.K. Lines warned that these disruptions are likely to drive up the cost of goods and contribute to long-lasting inflationary pressures worldwide, emphasizing the urgent need for supply chain diversification and resilience [1].
Rabobank’s RaboResearch Global Economics & Markets team noted that Brent crude prices have firmed, with near-dated Brent rising by $2 to $97, as markets react to the fragile ceasefire and ongoing disruption in the Strait of Hormuz [2]. Equity markets posted modest declines in Europe, while US stocks rose [2]. Shipping flows remain severely constrained, with Iran allowing no more than 15 ships per day to pass under the ceasefire agreement, compared to an estimated 800-900 vessels waiting to exit the strait [2]. Iran’s Ports and Maritime Organization has published 'two safe shipping routes,' reinforcing Iran’s effective control over the waterway and raising concerns that ship owners may remain reluctant to re-enter the area even after cargoes are delivered [2].
According to Fox News, oil traffic through the Strait of Hormuz remains effectively halted, with a backlog of roughly 3,200 vessels, including 800 tankers and cargo ships, idling west of the strait [3]. No oil tankers have risked the journey in recent days, and only a handful of vessels, mostly Iranian-flagged or dry bulk carriers, have transited the waterway, often through corridors near Iran’s Larak Island rather than standard commercial lanes [3]. Some ships are switching off tracking systems as they pass, and nearly 20,000 mariners are stranded in the Persian Gulf [3]. Cargo is increasingly being rerouted through ports in Oman and along the UAE's east coast, adding about two weeks to some voyages and increasing costs by approximately 25% [3].
President Donald Trump criticized Iran for not honoring the ceasefire agreement, which was supposed to ensure the "COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz" [3]. Analysts cited in the articles highlight that shipping companies have a lower risk tolerance than governments, and the risk of mines, missiles, or drones, along with elevated war-risk insurance premiums, is deterring vessels from resuming normal operations [1][3]. Shipping industry leaders warn of ongoing volatility in delivery schedules, pricing, and possible shortages in key industrial inputs, with analysts suggesting the situation may accelerate shifts in energy and manufacturing supply chains away from the Middle East [1].
CONCLUSION
The continued closure of the Strait of Hormuz amid the Iran War ceasefire has led to soaring oil prices, increased shipping costs, and significant supply chain disruptions. Market sentiment remains negative, with analysts and industry leaders expecting persistent volatility and inflationary pressures. The crisis underscores the urgent need for global supply chain diversification and resilience in the face of heightened geopolitical risks.
