Saudi Arabia warned of potential danger at Yanbu, a major Red Sea oil-export hub, amid ongoing Houthi attacks and recent Saudi-led coalition interceptions of missiles targeting key areas including Medina. There was no confirmed impact on Yanbu’s operations, and the Houthis did not claim responsibility for an attack that day. An earlier alert also covered Sharurah near the southeastern border. The Houthis had previously said they targeted Riyadh’s international airport, a claim Saudi authorities did not confirm. Market pricing indicates a low probability of a nationwide Saudi airspace closure by December 31; an earlier update put that probability at 10%. Markets assign a 29.5% chance to a Saudi-Houthi ceasefire. Saudi Arabia has sought defensive and offensive assistance from the United States, Europe and Middle Eastern countries. Egypt approved military assistance last month, Turkey is set to ratify a mutual-defence pact with Saudi Arabia and Pakistan containing a collective-defence clause, while Britain said in October it would deploy fighter jets on defensive missions to protect Saudi cities from Houthi aerial attacks. Further Saudi security statements, additional Houthi attacks and diplomatic efforts will be important indicators for prediction-market probabilities.
