Hormuz: The Energy Valve

4.9 mb/d · Oil and products transiting in Q2 2026 · Period: Q2 2026
A narrow sea lane can expose many importers at once, but a traffic collapse does not translate mechanically into the same percentage loss of global oil supply.
Separate ships using the strait from oil already stored, output redirected through pipelines, domestic production, and demand responses. The first-order shock is access to transport; the second-order shock depends on inventory, refineries, alternative routes and market expectations. EIA estimates traffic with vessel tracking plus inferred voyages because AIS signals can be missing or misleading.
The strongest alternative to “a single strait controls the whole economy” is that buffers, alternative export routes and demand adjustment prevent identical losses for every buyer. They are limited and unevenly distributed, but they exist. A fall in tanker transits should not be read as an equal fall in global oil consumption.
Reduced Hormuz tanker traffic is evidence of a trade-route shock, not a direct measure of world oil consumption.
EIA 2026 energy-security analysis: oil flow Q4 2025 = 21.6 mb/d; Q2 2026 = 4.9 mb/d; estimates derived from AIS plus additional reconciliation.
Some supply can be redirected, while inventories and changes in demand can buffer different buyers unevenly.
A later EIA volume revision, bypass utilisation, regional stocks and product-market data might change my conclusion.
Open the EIA chokepoint table. Compare the same unit and reporting basis across Q4 2025 and Q2 2026. Read EIA’s AIS reliability note before treating either number as exact. Cross-check oil, petroleum products and LNG separately; LNG is not measured in barrels per day in this table.

The 2026 traffic estimates are revised as tracking and inferred routes change. This edition is a snapshot, not a live shipping monitor.
