Iron Ore Prices: Fuel Costs Rise Amid Iran War & Strait of Hormuz Concerns
Iron ore miners face potentially billions of dollars in increased fuel costs as disruptions to shipping through the Strait of Hormuz continue, according to a warning from Fortescue, the Australian mining giant. The escalating crisis, triggered by U.S. And Israeli strikes on Iran following the killing of its supreme leader Ali Khamenei on February 28th, has prompted Iran to effectively block most shipping traffic through the vital waterway.
Fortescue executives stated that rising diesel prices, a direct consequence of the Strait of Hormuz closure and broader regional instability, will significantly impact profitability. Although the precise financial hit remains uncertain, the company anticipates a substantial increase in fuel expenses. This assessment aligns with broader market concerns about energy costs, as the Strait of Hormuz handles approximately 20% of global oil and liquefied natural gas supplies.
Gulf oil producers are scrambling to mitigate the impact of the blockage. Saudi Arabia is increasing flows through its East-West pipeline, which delivers crude to the Red Sea port of Yanbu, while the United Arab Emirates is boosting exports via the Habshan-Fujairah pipeline, connecting onshore oil fields to the Gulf of Oman. These pipeline routes offer an alternative to the Strait of Hormuz, but capacity is limited and cannot fully offset the disruption.
The situation is too driving up the cost of shipping, with tankers queueing offshore as they await safe passage. The International Energy Agency (IEA) has noted a steady increase in shipments through the bypass pipelines, but the overall impact on global energy markets remains significant.
While Fortescue anticipates higher costs, the company highlighted potential savings from its ongoing efforts to decarbonize and electrify its operations. Aggressive investment in these areas could partially offset the increased fuel expenses, yielding hundreds of millions of dollars in savings. However, the extent of these savings will depend on the speed and success of the transition.
The crisis extends beyond oil and gas, impacting the broader commodities market. Analysts at S&P Global have noted a rise in iron ore costs linked to the Strait of Hormuz disruption, though the precise mechanisms driving this increase are still being assessed. The situation is creating a complex interplay between safe-haven demand for metals and concerns about supply chain disruptions.
As of March 23, 2026, Iran continues to maintain its restrictions on shipping through the Strait of Hormuz. Diplomatic efforts to de-escalate the conflict and restore safe passage remain ongoing, but no resolution has been reached. The United States and Israel have not publicly responded to Iran’s continued closure of the strait.
