Iran's military declared the Strait of Hormuz closed on September 13, citing Israeli strikes against Hezbollah in Lebanon [1]. US Central Command simultaneously reported commercial oil tankers continued transiting the waterway [1] — a direct contradiction that underscores the gap between Tehran's claims and observed ship movements. CENTCOM also disclosed it has redirected 100 commercial vessels in 60 days under its Iranian blockade, asserting zero ships passed without US approval [2]. The protection framework for Hormuz transits narrowed further: US Naval Cooperation guidance now restricts ships to two specific daily time windows, down from broad overnight coverage, per FT-reported NCAGS emails [3]. Ships are told to begin transits around 9am; nighttime is no longer considered safest [3]. TankerTrackers reported zero Iranian crude crossing the blockade line in 60 days, while non-Iranian Gulf crude ship-to-ship transfers averaged 7.15M bpd over the past 14 days, up 56% from the prior month [4]. Insurance-based closure remains operative from Day 196: 6 P&I clubs withdrawn, VLCC war-risk at ~$10M [previous post]. A Gulf of Oman oil spill from the US-attacked tanker RIESCO doubled in size by Sep 13, threatening Omani and Iranian protected waters [5]. Iran-Oman talks September 14 may establish a safe-passage framework, but Tehran insists this is not an immediate reopening [4].
