Iran’s Hormuz blockade threatens oil supply, IEA warns of market underestimation

IEA chief Fatih Birol says markets are underestimating the Strait of Hormuz closure’s impact. Crude oil hitting $90 by June 30 is at 75% YES.

Birol’s warning comes as Iran’s blockade of the Strait of Hormuz continues to slash tanker traffic and spike energy prices. The June 30 market now shows increased probabilities of higher crude prices on supply disruptions. With 75 days until resolution, traders are pricing in further escalation.

The WTI Crude Oil market for April also reflects Birol’s warning. Odds of WTI hitting $160 are expected to surge if the disruption persists. Traders are bracing for potential spikes to $150–$200 per barrel if the strait remains closed.

At 75%, a YES share for June 30 pays $1 if crude hits $90. That price implies traders see a strong likelihood that the conflict continues to push oil higher. The market had already been moving toward elevated risk before Birol’s comments, but the IEA’s public warning adds institutional weight to what traders were already positioning for.

Watch for statements from Saudi Arabia’s Energy Minister and OPEC+ production decisions. Changes to output targets or any diplomatic developments around the strait could move these markets quickly.
