What it means
Active U.S. and Saudi airstrikes on Iran represent a genuine escalation beyond the ongoing tensions already covered — direct military engagement with a major oil-producing nation historically spikes crude prices, lifts defense stocks and gold as safe havens, and pressures broad equities in the short term. The Strait of Hormuz risk premium is the dominant channel here, given that roughly 20% of global petroleum liquids transit that chokepoint. These moves typically play out over the immediate trading sessions following a confirmed escalation of this magnitude. (Lower-conviction channels were filtered out by our selectivity bar.)
