China confirms attack on oil tanker in Strait of Hormuz amid regional tensions

China has now confirmed an attack on a Chinese-owned oil tanker in the Strait of Hormuz, the first time a vessel linked to Beijing has been hit amid the spiraling U.S.-Iran hostilities. The Islamic Revolutionary Guard Corps stands accused of striking multiple merchant ships, turning the world’s most important oil chokepoint into a no-go zone for commercial traffic.

That confirmation alone has already moved the markets. The prediction contract asking whether 20 ships will transit the Strait on any day by May 31 dropped from 76% YES to 67% YES in 24 hours; the odds of traffic returning to normal by May 15 collapsed from 4% to 2.4%. Traders are pricing in prolonged paralysis.

The halt in maritime traffic is not abstract. Insurance underwriters, diplomatic silence from the IRGC and U.S. Central Command, and the absence of any credible ceasefire path have combined to freeze commercial decisions. Observers tracking the region note that broader instability is now bleeding into every tanker schedule and premium quote.

What makes this episode different is the explicit targeting of “neutral shipping.” Until Beijing acknowledged its own ship had been struck, the pattern could be dismissed as collateral in a bilateral scrap. Now the circle of victims has widened, and the prediction markets have registered the shift faster than any government statement.

The data are unambiguous: volume on the May 15 normalization contract reached $680,000 while its price cratered to 1.9%. A separate contract on whether the Bab el-Mandeb Strait is effectively closed sits at 5.1% YES. Shippers are voting with their balance sheets.

The open question is whether insurance companies will formally declare the strait uninsurable, or whether a sudden diplomatic breakthrough can override the new reality that even Chinese tankers are in the crosshairs. Either way, the old assumptions about Hormuz traffic just evaporated.
