The Qatari LNG carrier Al Rekayyat (evacuated after an engine-room fire) and the Saudi supertanker Wedyan are struck — third vessel in 24h, breaching the ceasefire. LNG and crude threatened the same day: rerouting and insurance repricing.

35M barrels exit Hormuz as flows restart

~20 tankers (~35M barrels) exit Hormuz after the deal; flows recover toward ~4.8M bpd — far below the ~15M bpd prewar level. Crude stuck for three months finally reaches buyers; the throughput signals lasting constraint.

Comparable precedents

Red Sea, Dec 2023 – Feb 2024After a sequence of attacks, Asia–Europe freight rates tripled in ~8 weeks; the Joint War Committee extended its Listed Areas and war premiums repriced within ~7 days. Forwarders advised booking 4–5 weeks ahead.
Abqaiq, Sept 2019A drone strike on Aramco facilities removed ~5% of global supply; Brent jumped ~15% in one session before easing.
The "Tanker War", 1984–1988The long precedent for tanker targeting in the Gulf: naval escorts, durably elevated premiums, structural rerouting.

Methodology — Events detected continuously across thousands of sources (GDELT + press feeds), grouped into deduplicated situations. Corroboration counts independent originators: syndicated copies of one wire story are merged, so the figure shown is not a raw outlet count. The intensity curve measures our own ingestion on this topic.
