US military reimposes naval blockade on Iranian ports, launches new strikes
Context
US forces on Tuesday reimposed a naval blockade to prevent ships from sailing to or from Iran's ports and conducted strikes against the country for a fourth day in response to Tehran's attacks on commercial ships passing through the Strait of Hormuz and on Gulf facilities.
What it means
The imposition of a naval blockade is a meaningful escalation beyond the prior strike signals already in the chain — it directly restricts Iranian oil exports rather than just threatening transit, which has historically been associated with a fresh crude risk premium. Defense names and gold have historically seen additional bids when a conflict escalates to active naval enforcement. These moves build on an already elevated risk backdrop, so the incremental magnitude may be smaller than the initial shock. (Lower-conviction channels were filtered out by our selectivity bar.)
