(P1) Crude oil prices fell more than 2 percent on Saturday even as US President Donald Trump renewed military threats against Iran, with markets weighing mixed diplomatic signals ahead of a ceasefire deadline that could reopen the Strait of Hormuz. The move highlights deep uncertainty in a market rattled by the most significant disruption to global energy supplies in decades.
(P2) "You are only as strong as your weakest link in your supply chain, and so your suppliers’ suppliers and your suppliers’ suppliers’ suppliers could be dependent on ingredients impacted," warns Lisa Anderson, president of supply chain specialists LMA Consulting Group.
(P3) The war has already halted nearly a third of global helium supply from Qatar and cut off about 44 percent of sulfur exports from the Persian Gulf. The disruption sent UK diesel prices surging by 49 pence to 191.5p per liter since March, while the average US 30-year fixed mortgage rate climbed 48 basis points to 6.57 percent.
(P4) The conflict is forcing a systemic pivot from lean "Just-in-Time" inventory management to a more resilient, but inflationary, "Just-in-Case" model. With critical inputs for everything from semiconductors to fertilizer trapped by the conflict, companies are now building 60-90 day buffers, a costly insurance policy against future shocks that signals a new era of sustained price pressures.
The era of hyper-efficient, lean supply chains is over, shredded by the realities of the war in Iran. For decades, logistics revolved around minimizing inventory to cut costs, a philosophy built on the assumption of stable, open global trade routes. That assumption shattered when the Strait of Hormuz, a chokepoint for roughly 11 percent of global freight and a third of seaborne oil, was effectively closed.
Shipments timed to the hour were suddenly trapped or diverted on 4,000-mile detours. According to Supply Chain Brain, the conflict forced Middle Eastern countries to cut over two-thirds of their oil production. The impact extends far beyond energy, as crude oil is a manufacturing input for tires, plastics, and pharmaceuticals. The shift to a "Just-in-Case" model means warehouses are no longer cost centers but strategic assets, with demand surging for storage in "safe zone" hubs like Oman and Singapore.
A prime example of the cascading consequences is the disruption in the sulfur market. The Middle East accounts for about 40 percent of global sulfur exports, a key material for producing sulfuric acid. This acid is critical for refining battery metals like copper, cobalt, nickel, and lithium. With roughly half of the global seaborne sulfur trade transiting the Strait of Hormuz, availability has tightened dramatically.
This squeeze directly threatens copper production. Heap-leach operations, which rely on sulfuric acid, supply nearly 14 percent of the world's refined copper, or about 4 million tonnes annually. A sustained shortage could strip this volume from the market, exacerbating an existing copper deficit. Ivanhoe Mines (TSX:IVN) founder Robert Friedland warned that a prolonged closure could hobble copper producers, noting that realized prices for sulfuric acid have already surpassed $500 a tonne. The disruption also impacts silver, as about 30 percent of its production is a byproduct of copper mining.
The supply shock is rippling through the global economy, creating broad and sometimes unexpected inflationary pressures. The sulfur shortage is hitting phosphate fertilizer makers, which account for over half of demand. With a third of the world’s fertilizer supply passing through the strait, the agricultural industry is raising alarms about crop yields just as planting season begins in the Northern Hemisphere.
This energy and materials shock is rapidly becoming a food crisis. According to the Food and Agriculture Organization, the FAO Food Price Index climbed to 128.5 points last month, up 8 percent from March 2024. The conflict is also creating shortages in surprising areas. The City of Baltimore, for instance, cut fluoride levels in its public water system by nearly half after its supplier reduced deliveries due to the conflict. The price of gasoline and diesel has surged globally, with British drivers paying an average of 191.5p per liter for diesel, an increase of nearly 49 pence since the war began.
