The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. At its narrowest point, the transit channel consists of two 2-mile-wide shipping lanes separated by a 2-mile buffer zone. It represents the world's most critical energy chokepoint, facilitating the transit of approximately 20.5 to 21.0 million barrels per day (mb/d) of crude oil, condensate, and refined products—amounting to roughly 20-21% of total worldwide petroleum liquids consumption.

When regional conflicts escalate or diplomatic pacts falter (such as recent geopolitical headlines involving Iran, the US, and Gulf producers), physical transit risk triggers a two-pronged market pricing shock:

• Physical Supply Elasticity Shock: Global oil demand in the short term is highly inelastic (ε ≈ -0.04 to -0.06). A withdrawal of even 1.5 to 3.0 mb/d of net seaborne crude forces rapid upward price clearing to ration refinery intake.
• Maritime War-Risk & Freight Surcharges: Lloyd's Joint War Committee lists the Persian Gulf and Gulf of Oman as high-risk designated areas. Insurance syndicates instantly escalate Additional Premium (AP) rates on VLCC hull and machinery (from 0.025% of ship value to upwards of 0.5%–1.0%), adding $2.00 to $10.00+ per barrel in sheer freight friction before physical cargo delays are factored in.
• Bypass Limitations: The UAE's Habshan-Fujairah pipeline (1.5 mb/d) and Saudi Arabia's East-West Petroline to the Red Sea port of Yanbu (5.0 mb/d) offer roughly 6.5 mb/d of theoretical bypass capacity, leaving over 14 mb/d trapped inside the Persian Gulf if the Strait is rendered impassable.
