Hormuz Flows Halved as WTI Holds Near $90 and U.S. Crude Stocks Draw
Middle East tanker traffic has collapsed to 11 million barrels per day from 18 million, keeping WTI front-month elevated as U.S. inventories tighten sharply.
Middle East crude shipments have dropped to roughly 11 million barrels per day from 18 million bpd before the conflict began, according to Reuters data, with WTI crude front-month trading at $89.85 per barrel as of Tuesday (2026-09-22) as physical markets absorb a tightening supply picture.7
That compression shows in the EIA inventory data. U.S. commercial crude stocks fell 4.5 million barrels to 424.5 million barrels in the week ended August 28 (2026-08-28). A prior EIA report had recorded a draw of 7.17 million barrels, driven by refinery utilization running at 97.2% of capacity and consuming 17.3 million barrels daily.7,6
The pinch point is the Strait of Hormuz. Only seven vessels crossed on Monday (2026-09-07), according to FX Empire analysis, continuing a trend that J.P. Morgan had flagged in a report sent to Rigzone on Friday (2026-07-17). The bank noted that a "traffic recovery that began in early June" had "abruptly stalled," with confirmed flows falling to just 5.1 million barrels per day at that stage.7,3
The EIA put pre-conflict throughput through Hormuz at approximately 20 million barrels of crude and petroleum products per day in 2024, representing about 20% of global petroleum liquids consumption. Losing roughly a third of that volume, without a comparable alternative route, makes the U.S. inventory drawdowns partly structural.4,7
ICE Brent crude front-month was at $98.46 per barrel as of Tuesday (2026-09-22), a spread of roughly $8.60 over WTI. That premium widened as the conflict escalated through July (2026-07). On Sunday (2026-07-19), Brent touched $91.41 intraday before settling near $90.56, up 2.8% from a previous close of $88.10, while WTI rose 2.4% to $84.49. Both benchmarks have moved higher since.4
But the trade is not one-directional. On Monday (2026-07-27), Brent and WTI each fell more than 5%, with Brent confirmed near $91.73, as diplomatic signals briefly overwhelmed the supply arithmetic. Naeem Aslam at Zaye Capital Markets warned that "current demand estimates remain divided." OPEC projects global oil demand growth of roughly 0.8 million barrels per day in 2026; the IEA presents a softer consumption outlook.5
ANZ analysts said markets may need to revise expectations that Persian Gulf supply would recover quickly. Chris Beauchamp, chief market analyst at IG, noted that hopes for further progress in U.S.-Iran talks have weakened, an assessment that runs alongside the deteriorating vessel counts rather than against them.2,1
U.S. consumer sentiment offered a partial demand offset. Preliminary readings for Friday (2026-07-17) showed sentiment climbing to 54.4 from 49.5, with current conditions rising to 54.9 from 47.7. Still, a reading near 54 is historically subdued, and refinery utilization near capacity leaves the demand side with little room for further acceleration.3
Natural gas inventories as of early August (2026-08-04) were running 1% below year-ago levels, though 6.4% above the five-year average, leaving NYMEX Henry Hub front-month at $3.02 per MMBtu on Tuesday (2026-09-22) with little structural pull from the gas side to complicate the crude picture.6
Seven vessel crossings on Monday (2026-09-07) against pre-conflict throughput of roughly 20 million barrels per day is where the supply pressure is most directly visible. U.S. refinery utilization near capacity means any further compression in Hormuz traffic lands directly on crude stocks, with no meaningful buffer left to absorb an acceleration of the trend.7,6
