Iran tightens Strait of Hormuz control, dimming US peace deal prospects

Iran’s continued control of the Strait of Hormuz has cratered prospects for a US-Iran peace deal. The permanent peace deal by April 30 market is at 1.7% YES, down from 10% yesterday.

## Market reaction

Iran’s reassertion of its grip on the Strait has widened the gap between the two sides, making Trump’s agreement to Iranian demands for sanction relief less likely. The market for Trump agreeing to Iranian oil sanction relief in April dropped to 3.8% YES from 14% a day ago. The April 30 peace deal market fell in parallel, now at 1.7% YES.

## Why it matters

The peace deal term structure shows a telling spread. Odds for a deal by May 31 are at 28.5% YES, and June 30 at 46.5% YES. The 27-point jump between April 30 and May 31 suggests traders expect a possible catalyst in late May.

Trading volume is at $854,504 in USDC over the past 24 hours. But the order book is thin: only $119 is needed to move the oil sanction relief market 5 points, which means large trades could cause sharp swings.

## What to watch

Iran’s firm stance on the Strait makes a quick diplomatic resolution unlikely. A YES share in the April 30 peace market at 2¢ pays $1 if a deal emerges, a 50x return. That bet requires believing in a sudden breakthrough within six days.

Watch for announcements from Trump’s administration or Iranian officials signaling a shift in negotiations. A statement from a US special envoy or a change in Iran’s maritime policy could move these markets fast.
