Hormuz Blockade Threat Pushes Brent Past $103

Oil markets are pricing in escalating risk after Brent crude surpassed $103 per barrel following the breakdown of US-Iran nuclear talks, with analysts warning prices could reach $150 if Washington executes a threatened blockade of the Strait of Hormuz. The strait is the world's most critical oil chokepoint, carrying up to 12 million barrels per day, roughly one-eighth of global supply. A sustained closure at that scale would trigger an immediate supply shock with no viable short-term rerouting alternative. The mechanism is straightforward: reduced throughput forces competing buyers to bid up remaining supply, compressing refinery margins globally and hitting emerging-market importers hardest. Naval preparations signal the threat is more than rhetorical, though traders are currently pricing a full blockade as a tail risk rather than a base case. The spread between that market consensus and the stated policy posture is the key tension to monitor. Any confirmed interdiction or Iranian counter-move in the strait would rapidly reprice that probability, with cascading effects on energy equities, inflation expectations, and central bank rate paths.
