Oil: Ships Position in Gulf as Strait of Hormuz Set to Reopen

A tentative U.S.-Iran understanding that would reopen the Strait of Hormuz has prompted visible movement in Gulf shipping, with some tankers moving into transit positions, yet traders and shipowners remain cautious and full-scale oil flows are not immediate. Shipping-data providers and market analysts confirm that a handful of very large crude carriers have started to transit after lengthy delays, signaling a possible gradual resumption of exports.
The turning point came into focus in mid‑May 2026 when shipping data showed three supertankers crossing the strait carrying roughly six million barrels of Middle East crude, after waiting in the Gulf for more than two months. On May 23, 2026, U.S. President Donald Trump said a memorandum of understanding had been "largely negotiated" that would include reopening the waterway and steps on lifting aspects of the maritime blockade, though details remain under discussion and officials stress case‑by‑case approvals for transits.
Markets reacted to the improving diplomatic tone with reduced risk premia, but oil-price volatility persisted. While reports of tankers transiting eased some immediate panic, insurers, shipowners and charterers have signalled reluctance to return to pre‑crisis routings without clearer security guarantees and insurance cover. Crucially, a temporary opening of passage does not instantly clear the backlog of floating and onshore storage, nor does it automatically restart fields and terminals that were idled or damaged during the disruption.
From an economic perspective, the Strait of Hormuz has been a primary chokepoint: before the conflict it carried about one‑fifth of seaborne oil. Even if the corridor is formally reopened, restoring output to former levels requires coordinated logistics — crews and contractors back at terminals, repair of damaged facilities, and re‑establishing commercial insurance and escorted transit schemes. Those operational and commercial frictions are likely to stretch the recovery timeline into weeks or months.
Analysts outline a range of scenarios: a rapid phased recovery if security and insurance issues are swiftly resolved; a protracted rebound if logistical bottlenecks and infrastructure repairs drag on; or a structural reduction in flows if some fields or export routes remain impaired. The key near‑term indicators for markets will be the number of daily transits, insurance premiums for Hormuz voyages, refinery run‑rates in receiving regions, and onshore inventory trends — metrics that will determine whether the easing of political tensions translates into sustained price relief.
