US Navy destroyer intercepts oil tankers departing Iran’s Chabahar port

A US Navy destroyer intercepted two oil tankers departing Iran, enforcing a naval blockade. US escorts through Hormuz by April 30 sit at 21.5% YES, up slightly from 20% a day ago.

The interception signals active enforcement rather than passive posturing, which cuts against the scenario where the Navy shifts to escorting commercial ships through the Strait. The April 30 market shows a 20-point jump from April 15’s 1.8% YES, meaning traders price most of the remaining probability into the second half of April.

Daily volume on this market is $6,834 in USDC, with $2,903 in order book depth to move the price 5 points. That’s moderately liquid but thin enough that a single large order could shift the price meaningfully. The biggest move was a 1-point drop at 4:34 PM.

The blockade’s continuation puts pressure on related Strait of Hormuz traffic markets. No successful tanker transits have been reported, and odds for normal traffic by end of May are likely to stay compressed. Chabahar sits at the mouth of the Gulf of Oman, and continued interdiction there makes a quick return to normal oil flow unlikely.

For traders, buying YES at 22¢ pays $1 if the US Navy escorts a commercial ship through Hormuz by April 30, a 4.5x return. That bet requires believing in a diplomatic breakthrough within roughly 15 days.

Watch for CENTCOM statements or a White House briefing that could move these odds quickly. Any announcement of de-escalation or a shift from blockade to escort operations would reprice the market.
