- Vessel movements through the Strait of Hormuz plummeted to merely 5 ships daily, significantly below the recent 10-day average of 14 vessels

Crude oil markets experienced significant upward momentum on Tuesday following the resumption of military hostilities between Washington and Tehran, reigniting concerns about potential supply chain disruptions. Brent crude futures advanced to $91.87 per barrel, accompanied by U.S. West Texas Intermediate climbing to $87.15.
These benchmark contracts had already registered approximately 3% gains during the previous trading session, extending an upward trajectory fueled by escalating Middle Eastern tensions.
Military Hostilities Return Following Temporary Ceasefire
The current escalation originated when American military operations targeted Iranian defense installations on Larak Island, breaking several weeks of comparative tranquility. Tehran’s military apparatus responded by deploying missiles toward American military installations located in Jordan.
BREAKING: Iran has just struck an oil tanker with 3 anti-ship cruise missiles in the US-backed southern Omani corridor while completing an outbound transit in the Strait of Hormuz under US escort, per UKMTO.
The vessel is the Saudi VLCC oil tanker “SIDR.”

President Trump committed to delivering a forceful countermeasure, intensifying market anxieties that direct military engagement could expand and jeopardize energy sector assets throughout the Persian Gulf zone.
“These bring the potential for Iranian retaliation back into the equation,” said Tim Waterer, chief market analyst at KCM. “Both of those risks are being reflected in the firmer tone in crude prices.”
The Strait of Hormuz historically transported approximately one-fifth of worldwide oil supplies prior to hostilities erupting in late February. Iranian authorities effectively closed this critical waterway following combined U.S. and Israeli military operations against the nation on February 28.
Diplomatic initiatives spearheaded by Qatar and Oman aimed at reopening the strategic passage have thus far produced no tangible results.
Maritime Traffic Experiences Dramatic Decline
Maritime tracking information compiled by Kpler revealed that merely five commodity-carrying vessels navigated through the Strait of Hormuz on Monday, representing a substantial decrease from the 10-day moving average of approximately 14 ships. Notably, none of these five vessels were classified as liquid cargo tankers.
On Tuesday, the United Kingdom Maritime Trade Operations agency confirmed that a commercial tanker was impacted by three separate projectiles during its passage outbound from the strait. Authorities reported no human casualties or ecological contamination resulting from the incident.
Market analysts at ANZ observed that petroleum volumes transiting through Hormuz currently stand at approximately 6 million barrels daily, substantially beneath pre-conflict baseline measurements.
Crude oil throughput via this route had demonstrated modest improvement during recent weeks, but the newest wave of attacks threatens to reverse that fragile progress.
Emergency Reserves Approaching Critical Thresholds
America’s Strategic Petroleum Reserve experienced a drawdown of approximately 3.1 million barrels during the previous week, bringing current holdings to 286.6 million barrelsādangerously close to its lowest level in four decades. Trump announced that petroleum secured through a recently negotiated Venezuelan agreement would contribute to replenishing these reserves, although the delivery schedule for those volumes remains undetermined.
OPEC+ sanctioned an incremental production enhancement of roughly 188,000 barrels daily effective September, finalizing its scheduled output restoration plan. Russia simultaneously prolonged its diesel export prohibition through September 30, compounding strain on global refined petroleum product availability.
Industry analysts surveyed by Reuters in August project that crude oil valuations will maintain levels above $80 per barrel through the remainder of 2026 as maritime transportation disruptions persist.
