US blockades Strait of Hormuz after Iran peace talks collapse

The US announced a blockade of the Strait of Hormuz after peace talks with Iran ended without a deal. The US-Iran ceasefire by April 15 market holds at 100% YES, though the blockade announcement raises questions about whether that price reflects reality.

The US-Iran ceasefire market has sat at 100% YES across all timeframes, meaning traders had priced in a resolution as a certainty. The blockade announcement could break that consensus. The countries conducting military action against Iran by April 30 market sits at 4% YES, with traders assigning low probability to allied military strikes within the next 18 days.

Trading activity is light: $1,046 in USDC has changed hands in the military action market. Only $427 is needed to move the price 5 percentage points, meaning a single motivated trader could swing these odds on new information. The collapse of talks and the blockade are a clear escalation, but prices haven’t moved to reflect it yet.

The blockade signals a hardened US position, making concessions to Iranian demands in April less likely. With 18 days remaining, a YES share in the Trump agreement market would need a rapid diplomatic reversal to pay off. At current prices, the market is betting on an outcome that the blockade makes harder to reach.

Watch for CENTCOM announcements on military movements or statements from Pentagon officials, which would directly affect these markets. Any EU or UK response to the blockade also matters, since allied involvement would reprice the military action contracts.
