Hormuz transport volume 4.9 million barrels per day... below a quarter of pre-conflict levels

Oil and petroleum liquids shipped through the Strait of Hormuz fell to an estimated 4.9 million barrels per day in Q2 2026, less than a quarter of the 21.6 million bpd seen in Q4 2025 before the conflict, according to US Energy Information Administration estimates in its August 2026 Short-Term Energy Outlook. The EIA figures combine crude and petroleum liquids, so they do not represent a crude-only decline, and the agency's estimate underscores that flows depend on transport capacity to consuming markets as much as on production. The International Energy Agency had put 2025 Hormuz crude and product volumes at about 20 million bpd, roughly 25% of global seaborne oil trade. The collapse matters because the strait remains the world's most important oil chokepoint, so sustained low throughput would force buyers to rely on alternative routes and inventories. Watch next for updated EIA and IEA throughput estimates and whether volumes recover toward pre-conflict levels.
