Reasoning from this article
The article documents crude falling 5.5% on an unverified, subsequently denied report, while prices had traded above $100 the prior week. This price range ($88–$100+) driven entirely by Hormuz access signals a structural regime shift where chokepoint control functions as a market lever. The pattern generalizes: any conflict threatening a major energy transit corridor now creates a persistent geopolitical risk premium that overrides supply fundamentals, making global energy markets structurally more volatile and susceptible to diplomatic signaling.
