In August 2026, the monitor detected 570 vessel crossings of the Strait of Hormuz — 276 outbound toward the Gulf of Oman and 294 inbound toward the Persian Gulf. 63 of the outbound transits were crude, product or chemical tankers, together carrying an estimated 54.5 million barrels (deadweight × 95% load × 7.33 bbl/t — an AIS-derived lower bound; see methodology). The busiest day was 2026-08-22 with 33 crossings.

August 2026 in review

Averaged over the 31 days, that is 18.4 detected crossings and 1.76 million barrels of oil a day — about 9% of the roughly 20 million barrels a day that moved through the strait before the 2026 war. Compared with July 2026, detected crossings were down 17% and estimated oil outflow was down 52%. Bulk Carrier vessels made up the largest share of crossings (17%), followed by Cargo at 12%. The largest tanker to leave the Gulf was BRUNEI PROSPERITY (321,300 DWT) on 2026-08-14. For the wider arc, read the six-month shipping timeline; for what replaced the missing barrels, see Supply & Demand and Oil Storage.
