What it means
A naval blockade of Iranian ports and a confirmed Hormuz closure is a qualitatively new escalation beyond prior U.S.-Iran strikes — it threatens roughly 20% of global seaborne oil, which has historically been associated with large, immediate crude price spikes. Airlines face acute fuel-cost pressure, and gold typically draws a safe-haven bid when conflict reaches this severity. These moves go well beyond the ongoing tension already reflected in prior signals. (Lower-conviction channels were filtered out by our selectivity bar.)
