The US seizure of an Iranian ship near Hormuz has sent oil prices climbing over 6%, heightening supply concerns. Crude Oil hitting $90 by June now has a TBD% likelihood.

Market reaction

This move is rippling through several prediction markets as the US blockade escalates tensions. The Strait of Hormuz traffic normalization market sees odds of returning to pre-war levels by April 30 dropping sharply given new military activity. The likelihood of Trump agreeing to Iranian oil sanction relief in April sits at 43% YES, unchanged since the 24-hour spike.

The sanction relief market is volatile. A 10-point spike occurred at 2:39 PM, moving from 44% to 55% before settling. Traders are reacting quickly but with skepticism about sustained policy shifts. The market requires just $387 to move 5 percentage points, making it susceptible to large trades.

Why it matters

The Strait of Hormuz handles roughly a fifth of global oil transit. The latest naval blockade actions and Iranian threats make any swift resolution unlikely. With only 10 days left in April, traders are pricing in continued disruptions.

For crude oil markets, the immediate concern is supply. A YES payout for hitting $90 by June would be attractive if tensions remain high. Current geopolitical conditions support a bullish case, especially if disruption persists.

What to watch

Further US naval actions or Iranian counter-moves could shift these markets quickly. Specific statements from energy ministers or new OPEC+ output decisions are the next likely catalysts.
