Chinese cargo planes reportedly land in Iran, raising Strait of Hormuz tensions

Unconfirmed reports of four Chinese cargo planes turning off transponders and landing in Iran, potentially carrying arms, have put the Strait of Hormuz traffic normalization market at 45% YES for a May 31 deadline.

Market reaction

The Strait of Hormuz traffic returning to normal market has not moved significantly on the news, but an unconfirmed arms transfer would make normalization by May 31 less likely. With 45 days remaining, traders appear to be waiting for verification before repositioning.

In the Trump visit to China market, odds for an April 30 visit sit at 1.1% YES, down from 2% a week ago. The reports directly contradict Xi’s assurances to Trump about not supplying arms to Iran, which could further reduce the chance of a near-term diplomatic visit. The May 31 market is at 85.5% YES, suggesting traders still expect a later visit despite these tensions.

Volume in the May 31 market was $36,055 in USDC over the last 24 hours, with $3,425 needed to move the odds 5 points. The largest price move was a 1-point spike at 6:31 PM, consistent with traders holding positions until more concrete information emerges.

Why it matters

If confirmed, Chinese arms deliveries to Iran would complicate both Strait of Hormuz shipping normalization and US-China relations during the ongoing Israel-Iran conflict. A YES share in the Strait market is priced for a 2.22x return, attractive to those who doubt resolution within 45 days.

What to watch

Confirmation or denial from official sources would likely move both markets sharply. Specific triggers: IRGC statements, changes in shipping patterns through the Strait, shifts in rhetoric from the Trump administration, or responses from the Chinese Foreign Ministry.
