Watch ID: watch-global-oil Title: Global Oil Market and Supply Review Window Start: 2026-10-02T02:00:00Z Review Window End: 2026-10-03T02:00:00Z Generated At: 2026-10-03T02:18:00Z Status: Material market, reserves, and maritime-security change Material Change Summary: Brent settled at $102.25 per barrel, down $0.06 or 0.06%; WTI settled at $91.11, down $1.76 or 1.90%. The G7 agreed to release 100 million barrels of diesel and other reserves over four months, front-loading diesel within 20 days. A crude-oil tanker was struck near Oman, with crew safe and attribution unknown. Verified Developments: - Market snapshot: Brent $102.25/barrel, down $0.06 (-0.06%); WTI $91.11/barrel, down $1.76 (-1.90%). Observation basis: official futures settlement values reported by Reuters on 2026-10-02. Incident file: watch-global-oil__2026-10-02__brent-wti-settlements-lower.txt. - Operational event: G7 coordinated release of 100 million barrels of diesel and other reserves through the IEA, beginning immediately over four months with a substantial diesel release within 20 days. Publication time: 2026-10-02T14:38:55Z. Verification: official joint statement relayed by Reuters. Incident file: watch-global-oil__20261002T143855Z__g7-emergency-reserve-release.txt. - Maritime event: Crude-oil tanker struck by unknown projectile about 4 nautical miles east of Oman; crew reported safe and no environmental impact initially reported. Cross-linked incident file: watch-iran-us-conflict__2026-10-02__hormuz-tanker-projectile-strike.txt. - Supply flow: Reuters reported September LNG Hormuz shipments at the highest monthly level since the conflict began, while noting continued security and sustainability risks. Publication time: 2026-10-02. Verification: multi-provider shipping-data analysis. Unvalidated Claims: Responsibility for the tanker strike, vessel identity, damage level, and sustained implementation volumes for reserve releases were not yet established. Corrections: This brief supersedes the prior day's settlement snapshot with final October 2 settlements. Operational Significance: The reserve release directly addresses refined-product scarcity and helped pressure prices lower, but maritime attacks and constrained refining keep the risk premium elevated.
