**Deck**: Two Saudi crude tankers were hit by unidentified projectiles in the Strait of Hormuz as U.S. forces rerouted dozens of vessels and Iran warned it could block Persian Gulf oil exports if its own shipments are stopped. The combination turns a vital trade route into a pressure point for energy markets and global shipping.

Oil and shipping markets face a new test after attacks on Saudi‑linked tankers in the Strait of Hormuz coincided with U.S. naval moves and explicit Iranian threats to curtail Persian Gulf exports.

Maritime risk firm Marisks and ship‑tracking company Kpler said two supertankers carrying Saudi crude oil were struck by unidentified projectiles minutes apart late Monday while sailing out through the Strait of Hormuz. A separate account from security companies described two tankers loaded with Saudi crude being hit by rockets and other munitions with only a few minutes between the strikes as they tried to cross the strait around midnight. The reports available here do not specify casualties or pollution, but two large ships being damaged in quick succession at the world’s most sensitive oil chokepoint is enough to unsettle shipowners, insurers and energy importers.

At the same time, U.S. forces have redirected 84 vessels in connection with what officials describe as an Iran blockade, according to an official report. No details are given on which ships were rerouted or where they were sent, but a redirection on that scale implies longer voyages, higher costs and slower deliveries for some cargoes that would otherwise move through the Gulf.

Iranian parliamentary speaker Mohammad Ghalibaf has responded to U.S. pressure with a series of warnings. He says that if the United States tightens what he calls a siege or intensifies a blockade, Iran will respond militarily. In his words, if Iran is prevented from exporting oil from the Persian Gulf, "no one will be able to export oil" from the region. He also argues that Iran’s armed forces have full control of the Strait of Hormuz, claims U.S. ships are trying to pass the strait in small numbers, and says traffic is now far below the pre‑war level of at least 120 ships a day. Those figures and assertions cannot be independently verified here, but they underline Tehran’s effort to present Hormuz as leverage.

The practical risk for tanker crews and coastal states is that rhetoric and military posturing translate into more strikes or sabotage in one of the world’s narrowest shipping lanes. Loaded supertankers hit by projectiles face the danger of fire, loss of propulsion or a hull breach that could cause pollution and block channels. Insurers must now factor in the possibility of both longer‑range attacks and short‑range strikes whose origin may be unclear.

The strategic stakes are wider. The Strait of Hormuz is the main outlet for crude and fuel exports from Saudi Arabia, the United Arab Emirates, Kuwait, Iraq, Qatar and Iran. Even limited disruption raises transport and insurance costs and can ripple into fuel prices worldwide. If the perception takes hold that Hormuz is no longer a reliably safe corridor, some shippers may delay or divert cargoes, effectively tightening supply without any formal closure of the strait.

On the U.S. side, Iran envoy Scott Bessent has framed Washington’s approach as sustained economic and financial pressure. He says the United States is likely to announce a bank sanction this week and another next week and describes his role as making Iranian leaders want a deal after a previous memorandum of understanding failed. Bessent argues that Iran’s leadership has mismanaged an energy‑rich economy and says Washington is pressing partners to align on tougher measures.

For now, the confrontation remains a contest of threats, sanctions and limited attacks rather than an open battle. The risk is that a successful strike causing major casualties, a serious spill or the sinking of a ship in a narrow channel forces a rapid and less controlled escalation.

Signals to watch include any claim of responsibility for the latest tanker incidents, changes in tanker traffic patterns through Hormuz, visible shifts in Gulf insurance premiums, and whether either side moves from redirecting ships and issuing warnings to openly stopping or seizing vessels at scale.
