Houthi territorial gains along Yemen’s Red Sea coast, including the September 10–11 capture of Mokha port and Perim Island in the Bab al-Mandab Strait, have sharply elevated the risk of sustained attacks on commercial vessels. These moves follow the group’s July 2026 maritime blockade declaration against Saudi-linked shipping and subsequent strikes that damaged tankers such as the Encelia and NCC Masa. Freight rates on China–Saudi routes have risen 37 percent since late July, while war-risk insurance premiums have tightened and traffic through the strait declined 18 percent in August. Saudi oil exports have shifted further toward the narrow waterway after the Strait of Hormuz closure, amplifying exposure. Traders are pricing elevated near-term disruption probabilities amid ongoing Saudi airstrikes, potential U.S. responses, and seasonal shipping volume patterns that could either constrain or enable further Houthi operations through year-end.

Attacks on military vessels will not be considered.
Missile/drone strikes targeting a ship that are intercepted or otherwise do not directly impact the vessel will not be considered, regardless of damage through debris.
Seize control refers to Houthi forces forcefully boarding and taking control of a commercial ship.
Qualifying incidents include, but are not limited to, drone and missile strikes, aerial bombings, and kinetic actions carried out by Houthi operatives in person, such as seizing a ship by force.
The primary resolution source for this market will be a consensus of credible reporting.
If a kinetic incident occurs, but, on the specified date, 11:59 PM AST, material ambiguity remains as to whether the incident can be attributed to Houthi operatives, this market may remain open for an additional 3 calendar days, AST. If, at such time, attribution of the incident still cannot be confirmed, this market will resolve to “No”.
