Iran Is Bombing Ships on the New Hormuz Bypass Route — and 20% of the World’s Oil Trade Is in the Crossfire

Following coordinated U.S. and Israeli airstrikes under Operation Epic Fury in late February 2026 that killed Iranian Supreme Leader Ali Khamenei, Iran announced on March 4 that the Strait of Hormuz — through which approximately 20 percent of the world’s traded oil and liquefied natural gas passes — was closed to unauthorized shipping [4]. In response, Oman and the International Maritime Organization established a temporary alternative transit corridor running along Oman’s coastline on the Musandam Peninsula, open toll-free to all commercial vessels for a 60-day period. The first coordinated convoy used the new route on June 25, led by the vessel Stoic Warrior and including the container ship Maersk Baltimore, both completing successful transits [1].

Iran’s Islamic Revolutionary Guard Corps immediately rejected the corridor, stating it had been established “without prior notification to or coordination with the Islamic Republic of Iran” and declaring it “unacceptable.” The IRGC asserted that “the only authorised transit routes through the Strait of Hormuz are those designated by the Islamic Republic of Iran” [1, 3]. In the days following the corridor’s opening, at least one cargo vessel was struck by a suspected Iranian drone while transiting the Omani-approved route, according to the British military [3]. Maritime intelligence firm Windward reported that nearly half of inbound commercial traffic through the region had already been diverting to the new corridor before the attack [2].

Why It Sucks:

Global Shipping Industry & Energy Importers

• The corridor works — but Iran just proved it can still be targeted. Nearly half of commercial traffic was already diverting to the Omani route, and vessels including the Maersk Baltimore completed successful transits — but Iran’s drone strike on a ship traveling the IMO-designated corridor proves that physical distance from the main strait does not guarantee safe passage for any commercial vessel in the region [1, 3].
• Twenty percent of global oil trade is still inside an active war zone. The Strait of Hormuz carries roughly 20 percent of the world’s traded oil and LNG; with Iran targeting the alternative route and the main strait still contested, energy markets face an extended period of elevated risk premiums on Middle Eastern crude, with no clear diplomatic resolution in sight [2, 4].
• War-risk insurance premiums are making the economics impossible for smaller carriers. Premiums for vessels transiting the Persian Gulf have surged since Iran declared the strait closed in March; the confirmed attack on a vessel using the IMO corridor will further harden underwriters’ positions, potentially pricing smaller independent shipping companies out of the region entirely and concentrating trade in the hands of carriers large enough to self-insure [3, 4].

Iran & the IRGC

• Tehran’s greatest geopolitical tool is being structurally dismantled without its consent. Iran’s ability to threaten Hormuz closure has underpinned its leverage over Gulf states, global energy consumers, and the United States for decades. The IMO-Oman corridor — established without consulting Tehran — is a direct attempt to make that leverage structurally obsolete, and from Tehran’s perspective, acquiescing to it would be strategic self-disarmament [1, 2].
• The new route was established in violation of Iran’s jurisdictional claims. The IRGC argues the Musandam corridor runs through waters under its strategic jurisdiction and that Oman and the IMO acted unilaterally — a position with legitimacy under international frameworks governing straits used for international navigation, where transit states retain meaningful consultation rights [1, 3].
• Allowing the corridor to operate freely would permanently normalize Iran’s irrelevance. If the 60-day corridor functions successfully without Iranian authorization, it sets a precedent that the international community can simply route around Iran’s strategic position. Attacking vessels on unauthorized routes is not recklessness from Tehran’s perspective — it is a calculated necessity to demonstrate the corridor is not safe, which is the only argument that preserves their remaining leverage [1, 2].

Gulf Maritime States (Oman, UAE, Saudi Arabia)

• The corridor is the payoff for years of costly strategic infrastructure investment. Saudi Arabia’s East-West Pipeline and the UAE’s expanded Fujairah crude export terminal were both built specifically to provide bypass capability in a Hormuz closure scenario; the current crisis has finally operationalized infrastructure the Gulf states have invested billions in over the past decade [2, 4].
• Oman’s unique neutral-broker status is now openly at risk. Muscat has historically positioned itself as a diplomatic back-channel between Iran and the West, facilitating nuclear negotiations and prisoner exchanges. By co-sponsoring the bypass corridor with the IMO, Oman has taken an explicit side in the conflict for the first time — creating potential long-term damage to the diplomatic credibility that has been its most valuable regional asset [1, 3].
• The corridor’s 60-day expiration creates dangerous uncertainty for Gulf energy revenues. The Omani corridor was established as a temporary 60-day measure, meaning its legal and operational status must be renegotiated or allowed to expire in late August 2026. Gulf states have built their near-term energy export strategies around its continued operation; Iran’s attacks raise the real possibility that shipping companies will abandon the route before that deadline, leaving Gulf crude exports in limbo [1, 2, 4].
