Iran asserts control over Strait of Hormuz, accuses Europe of hypocrisy

Iran’s foreign ministry claims legal rights to manage the Strait of Hormuz and accuses Europe of hypocrisy. Trump’s Hormuz blockade lift odds on the May 31 market sit at 78% YES, down from 90% yesterday.

Market reaction

The May 31 market dropped 12 points in a day. The short-term April 19 market fell harder, from 28% to 8% YES. The UK warships market also slid, from 12% to 8.5% YES. Traders are skeptical about diplomatic progress with 43 days left on the May 31 deadline.

Why it matters

Iran’s claim to regulatory authority over the strait shifts the dispute from selective maritime restrictions toward broader sovereignty assertions. This makes a negotiated blockade lift harder, because any US announcement would now implicitly concede or contest Iran’s legal framing. Iran’s assertive posture could also provoke a naval response from allied forces looking to demonstrate presence in the strait.

What to watch

Actual USDC daily trading volume is $29,602 across these markets. The May 31 market’s depth suggests $1,419 moves it 5 points, so thin liquidity could amplify swings. The largest single move was a 5-point drop at 12:19 PM. Watch for Trump’s responses on social media and any naval activity announcements from allied nations, both of which would move these markets quickly.

Buying YES shares at 78¢ yields a 1.28x return if resolved YES, but confidence in a diplomatic resolution by May 31 is falling.
