Houthi rebels backed by Iran say they will keep attacking Saudi energy infrastructure and airports. Strikes hit Saudi Aramco's Riyadh headquarters (13 Oct), a Dammam airport and a Shaybah oil site. Several oil majors pulled executives from the World Petroleum Congress, and Saudi Arabia postponed its FII investment conference to 2027. For a Thai SME, the practical effect is a higher risk of oil and fuel price swings, freight and shipping disruption through the Gulf, and some caution on Gulf trade and travel. Review fuel and shipping cost assumptions and keep an eye on diesel prices.
