Brent crude traded above $100 a barrel as conflict sharply reduced Strait of Hormuz shipping and threatened alternative routes through the Red Sea. Most commercial shipping through the Strait of Hormuz had halted or been delayed during the conflict. Before the disruption, about one fifth of the world’s oil supply moved through the strait. Oil prices respond to expected future availability as well as confirmed physical losses.
Brent crude exceeded $100 a barrel as markets priced the transportation risk. Saudi Arabia relied more heavily on routes to the Red Sea when Hormuz traffic declined. The Strait of Hormuz connects Gulf exporters with global customers through a narrow maritime corridor. Bab el-Mandeb and the Suez route offer alternatives for some cargoes but are not perfect substitutes for every destination.
Drone attacks and Houthi territorial gains placed additional pressure on those alternatives. Longer voyages require more ships and fuel to move the same volume of cargo. Strategic reserves can cushion temporary shortages but do not repair shipping routes.
Insurance and security costs rise when operators assess a greater chance of attack. Retail diesel and gasoline prices had begun to reflect the increase in crude and transportation costs. Price effects vary by refinery, product, transport distance and government policy. The duration of route restrictions and the amount of permanently lost supply were not yet known.
Price transmission occurs on different schedules. Spot crude markets react immediately to risk, shipping contracts and insurance adjust as voyages are booked, and retail fuel prices change as replacement inventory reaches stations. A $100 benchmark records the market at a moment in time; sustained household effects depend on how long the disruption lasts and how much supply producers can redirect through pipelines, storage and other ports.
What to watch: Verified tanker traffic and export volumes through each corridor. Producer, reserve-release and shipping-insurance decisions.
