Hormuz Flow Data Challenges the Case Behind Oil's Ceasefire Selloff
Brent shed 7% on the US-Iran strike pause but confirmed Strait throughput had already stalled near multi-month lows before the ceasefire arrived.
ICE Brent crude front-month fell as much as 7% in early Asian trading on Monday (2026-07-27), briefly dipping below $90 a barrel after Washington and Tehran announced a pause in strikes in West Asia, CNBCTV18 reported. By that session's close, Brent had recovered to approximately $91.73, according to analysis from Naeem Aslam, CIO at Zaye Capital Markets, sent to Rigzone.5,4
Markets have since stabilised. Brent was last quoted at $91.04 at Friday's (2026-08-01) close before weekend trading halted, roughly $10 below the $100.69 front-month print mid-morning Thursday (2026-07-23), when escalating Houthi attacks on Red Sea shipping briefly pushed the contract to $101.01 intraday, according to OilPrice.com. The working assumption across desks is that a ceasefire pause warrants pricing out the geopolitical uplift. But the physical data did not support that read before the announcement, and nothing in the packet suggests it does now.3
A J.P. Morgan report sent to Rigzone on Friday (2026-07-17) found that Hormuz traffic recovery, which had begun in early June, had "abruptly stalled." Confirmed flows through the Strait had fallen to just 5.1 million barrels per day, according to that analysis. That reading predated both the late-July Houthi escalation and the Monday (2026-07-27) selloff, meaning the flow deterioration was already underway before crude touched $100 and before the ceasefire drove prices back.2
The prior ceasefire set the template. In early June, traders priced in a quick restoration of Middle Eastern supply, and by early July tankers were again departing from the Strait, FX Empire reported, with markets factoring in near-term flow recovery. That optimism proved short-lived. Flows stalled again by mid-July, then Houthi attacks on commercial Red Sea shipping drove Brent through $100 for the first time in nearly two months. Brent climbed roughly 20% in about two weeks through late July, OilPrice.com noted.1,3
That rally has not been reversed. Even after the Monday (2026-07-27) correction, Brent prices are up more than 20% for July as a whole, CNBCTV18 reported. Traders are responding to a diplomatic announcement while the underlying supply dislocation — impaired Strait throughput — has not demonstrably improved. A ceasefire and a supply restoration are separate events. The market has conflated them twice in two months.4
The demand picture muddies the picture further rather than resolving it. Aslam noted in his Monday (2026-07-27) analysis that "current demand estimates remain divided." OPEC projects approximately 0.8 million barrels per day of global oil demand growth in 2026, while the IEA presents a softer consumption outlook, he wrote. U.S. consumer sentiment data from Friday (2026-07-17) offered a marginally more constructive read — preliminary sentiment rose to 54.4 from 49.5, with current conditions up to 54.9 from 47.7 — but neither data point settles the agency-level disagreement over where demand is heading.5,2
For those positioned long, the contrarian case sits in the J.P. Morgan throughput figure. If confirmed Hormuz flows remain at or near the 5.1 million barrel-per-day level reported in mid-July, the premium priced out of Brent on Monday (2026-07-27) came out too fast. The June ceasefire produced exactly that sequence: relief rally reversed on physical disappointment, followed by a fresh 20% rally when flows failed to recover.2,1
For bears, the parallel argument is available. WTI front-month dropped toward the $80 mark on Monday (2026-07-27), down around 4%, CNBCTV18 reported, and currently sits at $84.67. If demand is tracking the IEA's softer view and supply does gradually return through the Strait, the demand side of the ledger could do what the ceasefire started and push prices toward — or through — the lower end of the recent range. Two diverging macro forecasts from OPEC and the IEA do not both get to be right.4,5
The test is in the throughput data, not the headlines. Actual Hormuz flow readings over the coming sessions will either validate the Monday (2026-07-27) selloff or expose it as another round of geopolitical de-risking that the physical market eventually corrects. The June episode, when traders backed away from the supply-shock thesis only to see flows stall and prices climb 20% in a fortnight, gives that risk a precedent.2,1,3
