US-Iran tanker attacks cut Hormuz shipping to 4-month low; Iran plans no-go zone

Reciprocal US-Iran attacks on tankers in the Strait of Hormuz have driven shipping volumes to their lowest since May, with Iran announcing plans to establish a no-go zone. The escalation marks a direct threat to the world's most critical oil chokepoint, raising supply disruption risks. The no-go zone, if enforced, would represent a significant escalation in maritime conflict.
