Brent next close +8.3% · +7 days +34.2% · transits 83.6 → 11.4 per day · outsized reaction — bigger than 98.6% of pre-crisis days

Attribution caveat: 1 other major event(s) sit inside this one's ±7-day window (2026-02-28 IRGC declares Strait of Hormuz closed to commercial shipping), so the reaction is not cleanly separable.
