What it means
An actual halt to Strait of Hormuz shipping — not merely a threat — is a genuine escalation beyond prior signals and has historically been associated with sharp spikes in crude and natural gas prices, large drops in airline stocks due to fuel costs, and gains in defense names. The new element here is the confirmed stoppage of tanker traffic and active US-Iran fighting, which adds material new information beyond the 36-day 'closure risk' narrative already in prices.
