US Energy Secretary Chris Wright told Fox News on Sep 27 that oil flows through the Strait of Hormuz averaged nearly 13 million barrels per day, with one day this week exceeding 20 million barrels — more than pre-conflict levels [1]. Wright said US forces are facilitating oil, gas, refined products, and fertilizer transits. This contrasts with Treasury Secretary Bessent's Sep 11 statement that Iranian oil exports through Hormuz reached zero; the two figures may measure different things (all oil vs Iranian oil only) [1].

Iran's Persian Gulf Strait Authority (PGSA) warned Sep 27 that charterers forcing ships onto unauthorized routes will be added to a non-compliance list, with restrictions on all their vessels' future Hormuz passage [2]. PGSA published a letter from an unnamed vessel's owners apologizing for an unauthorized transit, saying the charterer ordered the ship without required declarations [2].

UKMTO's Sep 27 assessment says commercial shipping through Hormuz remains ~75% below prewar levels, with 26 of 43 projectile incidents since Jul 26 on the southern Omani route [3]. Tankers make up most passing vessels.

Kpler data published Sep 25 shows crude flows of 33.7M barrels for the week of Sep 20 (19 tankers, 17 VLCCs), but commodity transits fell to 9 on Sep 25, below the 10-day average of 18 [4]. Eight of nine tracked vessels exited; only one entered [4]. Oil passage through Hormuz remains unconfirmed from independent counts; AIS-dark vessels are not counted [4].

Gulf of Oman ship-to-ship transfers hit maximum capacity as Saudi Arabia rerouted crude via Hormuz after the East-West pipeline attack, surging from 900k b/d to 3.6M b/d in September [5]. Transfer times extended to 10+ days; 60M+ barrels sold through STS off Sohar [5].
