Yemen's Houthi forces struck two Saudi-flagged oil tankers in the Red Sea overnight, the Korean investment blogger Meru writes, and the choice of target matters more than the strike itself, since these were Saudi-owned vessels rather than foreign carriers hauling Saudi crude, suggesting the Houthis are following through on a warning issued days earlier. On July 20, the group told global shipping firms by email that it would treat any vessel loading or unloading cargo at Saudi ports as fair game, foreign flagged or not. Meru notes the two ships hit, the product tanker Encella and the VLCC Laila, are owned by Bahri, Saudi Arabia's state shipping line majority owned by the sovereign wealth fund and Aramco. Foreign tankers are not waiting to find out if the threat extends to them, Reuters has already counted at least seven vessels reversing course out of the Red Sea, and the EU is advising ships tied to Israeli, US, or Saudi interests to avoid the Red Sea and Gulf of Aden until threat levels ease. Meru points out the Houthis hold a geographic advantage that has frustrated past US strikes, mountainous terrain riddled with tunnels and bunkers that a 52-day American bombing campaign in 2025 could not fully destroy despite hitting roughly 1,000 targets. His read is that war-risk insurance premiums on Saudi port calls are already climbing, which quietly raises the delivered cost of Middle East crude regardless of whether the blockade escalates further.
Why it matters · Targeting Saudi-owned ships first, after warning that any vessel touching Saudi ports is fair game, is how a blockade escalates in stages rather than all at once, and rising war-risk insurance on Gulf shipping raises the delivered cost of oil quietly even before a single foreign tanker is hit.
Worth asking · The Houthis hit Saudi-owned ships first but have explicitly warned any vessel touching Saudi ports is a target. If foreign flagged tankers get struck next, does that change how you'd position in oil and shipping names, or is this already priced in after weeks of escalation?
