Iran condemns US attack on ship, escalating Strait of Hormuz tensions

Iran’s Foreign Ministry called a US attack on an Iranian ship “maritime piracy,” raising tensions in the Strait of Hormuz. The odds for 80 ships transiting the Strait by April 30 are at 29% YES, up from 26% yesterday.

Market reaction

The condemnation complicates an already fragile ceasefire. The market for Strait of Hormuz traffic returning to normal by June is pricing in more risk of prolonged disruptions. Odds for shipping traffic returning to normal by May are expected to decrease as well.

Volume sits at $18,559 in daily face value and $5,289 in actual USDC. It takes just $2,087 to move the market 5 points, meaning large trades can shift prices quickly. The biggest price move was a 6-point spike at 10:01 AM, right as the news broke.

Why it matters

This condemnation signals a real potential for escalation beyond rhetoric. The ceasefire is unstable, and further military actions could shut down shipping lanes in the region. A YES share at 29¢ pays $1 if 80 ships transit by April 30, a 3.45x return, but that payout reflects how unlikely traders consider the outcome given rising tensions.

What to watch

Statements from CENTCOM or changes in US naval posture in the Strait. Any sign of de-escalation or ceasefire extension would move these markets.
