Situation

The Strait of Hormuz remains effectively closed to normal commercial traffic, with Reuters reporting that vessels are only trickling through as regional tensions persist. IMF PortWatch recorded 8 transits on 2026-09-13, against a pre-crisis baseline of 85 per day, reflecting the sustained near-total suppression of throughput that has characterized the closure since February. Brent crude stood at $101.74 as of 02:49 UTC, a move of -2.05% over the prior 24 hours. On the diplomatic front, The Hindu reports that parliament speaker Ghalibaf has said the Strait of Hormuz will not reopen until Iran's conditions are met, a position consistent with background already established in this series; Times of India and ANI News carry related headlines stating Iran rules out reopening the strait or returning to US talks until its conditions are met, though no major wire in this feed independently carries those specific claims. A drone strike on an LPG tanker with nine Indian crew members near the strait is reported by Hindustan Times as a single-source item, with crew described as safe; the attacker has not been identified in that report. The Iranian army's claim to have shot down a drone over the strait carries no major wire attribution in this feed. Sixty-three events have been indexed in the last 24 hours across the monitored area. As of 02:49 UTC, 468 AIS-visible vessels were holding position away from berth in the Strait of Hormuz and Gulf watch box, a count that leaves out ships within 25km of a working port. On the Hormuz Index, Crisis Pressure, the state composite, sits in the extreme band, flat over 24 hours, with physical transit deviation as its top contributor; the Escalation Forecast sits in the elevated band, flat over 24 hours, with the Brent-WTI forward spread as its top contributor.
