Iran, US blockades halt traffic in Strait of Hormuz amid geopolitical standoff

Traffic in the Strait of Hormuz is at a standstill due to simultaneous blockades by Iran and the US. The probability of Trump announcing a blockade lift by May 31 has dropped to 82.5% YES, down from 83% a week ago.

Market reaction

The market on Trump lifting the blockade has barely moved despite the dual blockade news, with traders showing caution. With 41 days left, daily trading volume is $18,073.

The market on the UK sending warships through the Strait by April 30 sits at 8.5% YES. Total USDC traded is just $47, and only $708 would be needed to move the market 5 points.

Why it matters

The simultaneous blockades represent a direct geopolitical standoff between the US and Iran over the world’s most trafficked oil chokepoint. The thin volume on the UK warship market suggests traders see little chance of allied military involvement. The blockade lift market’s near-flat movement, despite escalation on the ground, points to traders pricing in an eventual resolution but not a fast one.

What to watch

At 18¢, a YES share in Trump’s blockade lift market pays $1 if it resolves, a potential 5.5x return. That bet requires a diplomatic breakthrough within 41 days. Watch for statements from CENTCOM, changes in naval deployments, and any shift in US diplomatic posture toward regional allies.
