Express News | U.S. air defense time windows restricting oil tanker transit through the Strait of Hormuz

Following an escalation in U.S. efforts to counter attacks on vessels navigating at night, the United States has mandated that tankers transiting the Strait of Hormuz operate only during specific time windows to receive military protection. Since May, Washington has provided air cover to ships opting for routes along Oman's southern coast, aiming to deter Iranian attacks and ensure the continued export of some oil from the Gulf. Shipowners must submit applications to the U.S. Naval Coordination Center for Shipping (NCAGS), which then issues navigation coordinates to crews and authorizes passage during broad nighttime windows, during which U.S. warplanes provide escort. Emails obtained by the media, sent from NCAGS to maritime advisors, reveal that in early September, these transit windows were narrowed to two fixed time slots each day. Vessels were instructed to set sail at designated times—such as 9 a.m.—with one email stating: "We are currently offering dynamically adjusted recommended transit windows. While vessels are not required to transit within these windows, adherence is advised to maximize protection." Another message noted that, given the threats facing merchant shipping, "it has become clear that nighttime transit is not the safest period of the day." (Financial Times)

Tanker freight rates have surged to 4.5 times the baseline benchmark, with the war costs of Middle East conflicts being factored into the price of every barrel of crude oil.

This week, freight rates for very large crude carriers (VLCCs) on the Gulf of Oman-to-China route surged to Worldscale 450 points (equivalent to 4.5 times the benchmark rate), translating to approximately $11.50 per barrel and setting a record high since the inception of this route. Meanwhile, ongoing military exchanges between the United States and Iran continue to constrain available shipping capacity in the Gulf, while VLCC freight rates on the West Africa-to-Asia route have also hit historic highs.

As net long positions in WTI crude oil hit a 20-week high, the Trump administration is considering invoking the Defense Production Act to expand refining capacity.

Executives at refining companies stated that new refineries require several years to become operational, leading them to prioritize improving the efficiency of existing facilities. Currently, the average price of diesel in the United States has surpassed $6 per gallon for the first time, while gasoline prices remain elevated, and refinery utilization rates have reached approximately 98%. According to data from the CFTC, as of the week ending September 8, net long positions in NYMEX WTI crude oil hit a 20-week high, and net long positions in gasoline reached a nine-month high.
