What it means
Trump's move from implied closure risk to an active military blockade and toll on Hormuz cargo represents a genuine escalation beyond what was already priced in — historically associated with a fresh crude risk premium, direct cost shocks to shipping operators, and a lift to defense stocks. The crude call extends and deepens prior signals rather than repeating them, as enforcement is now formal rather than threatened. (Lower-conviction channels were filtered out by our selectivity bar.)
