Gulf oil shipping price transparency breaks down as Hormuz market freezes

A new analysis by Pole Star Global reveals that transparent price discovery in Gulf oil shipping effectively broke down during the War phase following the closure of the Strait of Hormuz, with the majority of remaining fixtures no longer disclosing publicly quoted freight rates.

During the War phase - following Operation Epic Fury on 28 February and the IRGC's physical closure of the strait on 5 March - 59% of the 64 recorded Hormuz oil fixtures carried undisclosed freight rates, up from consistent disclosure in all prior phases.

The analysis covers 30,943 clean fixtures from Pole Star Global's Daily Broker Exchange dataset between December 2024 and 27 March 2026. Throughout all phases prior to 28 February 2026, Worldscale rate disclosure was consistent across Hormuz-loading fixtures.

“The public can see oil prices and satellite images of ships at anchor. What they cannot see is what is happening at the contract level,” explains Matt Morgan, Chief Product Officer at Pole Star Global. “When the majority of fixtures carry no disclosed rate, no one has a reliable basis for judging when this market returns to normal. The forward curve is pricing a summer ceasefire, but the fixture data shows a market that has stopped reporting its own prices. Those two signals are contradictory.”

The volume collapse reinforces the picture. Hormuz-origin fixtures held a stable 20–24% share of global oil fixture activity from December 2024 through February 2026. By March 2026 that share had fallen to 5.4%, concentrated after 5 March when fixture activity from Hormuz ports effectively ceased for transparent price discovery. Global fixture counts for the same period remained at normal levels, confirming the disruption was Hormuz-specific rather than a broader market slowdown.

The Strait of Hormuz carries approximately 21 million barrels of crude and refined products per day, roughly one-fifth of global petroleum consumption. Unlike the Suez Canal, there is no viable bypass route for Gulf-origin crude, meaning any sustained closure forces buyers to source from alternative basins at higher delivered cost or draw down strategic reserves.

Fixture failure rates rose to 6.0% in the War phase from a 4.7% baseline, consistent with counterparty uncertainty and force majeure clauses being invoked on existing commitments.
