By attacking just a few ships, Iran creates enough perceived risk to make insurance carriers unwilling to cover vessels transiting the Strait of Hormuz. This effectively disrupts 20% of the world's oil supply without needing a large-scale military blockade, a key tactic in asymmetric economic warfare.

The oil supply shock isn't simultaneous. It's a rolling disruption dictated by shipping times, hitting Asia first due to its reliance on Gulf crude and shorter voyages (10-20 days). Africa, Europe, and finally the U.S. (35-45 days) feel the impact sequentially, buffered differently by regional inventories.

The closure of the Strait of Hormuz exposed unexpected global dependencies on the Gulf region. Beyond oil and LNG, the disruption hit supply chains for fertilizer, petrochemicals, sulfur, and even helium, which is critical for the Taiwanese semiconductor industry. The crisis underscored the Gulf's broad economic integration.

A likely outcome of the conflict is Iran establishing control over the Strait of Hormuz and charging tolls for passage. This would mirror Russia's control over the Northern Sea Route, fundamentally altering freedom of navigation and creating a new economic reality where a state actor monetizes a critical global chokepoint.

Energy disruptions in the Strait of Hormuz create a cascade effect far beyond fuel prices. The resulting shortages impact petrochemical and fertilizer production, threatening key inputs for everything from manufacturing and electronics to agriculture and basic services like cooking gas for restaurants.

The conflict's impact extends far beyond crude oil, disrupting refined products, and energy-intensive commodities produced in the Middle East. This includes aluminum, fertilizers (affecting agriculture), helium (for chips), and even the sulfuric acid needed for copper mining, creating broad, underappreciated supply chain risks.

The disruption in the Persian Gulf affects not just the headline commodities of oil and gas, but also crucial dry bulk goods. Outbound fertilizers and aluminum, along with inbound raw materials for production, are significantly impacted, causing spikes in global markets for these specific goods.

The conflict's primary impact on oil is not that supply is offline, but that its transport through the Strait of Hormuz is blocked. This distinction is key to understanding price scenarios, as supply exists but cannot be delivered.

Global supply chain disruptions are not universally negative; they create niche economic booms. When Houthi attacks forced ships to bypass the Red Sea and circumnavigate Africa, ship fuel suppliers in Southern African ports saw a massive, unexpected surge in business as they became essential refueling stops on the new routes.
