US crude oil: fluctuating upward, buying on dips

(1) Analysis rationale: Houthi forces attacked Yanbu Port, oil fields, and airports in Saudi Arabia. For the first time, Saudi Aramco carried out a large-scale evacuation of its Dhahran headquarters, with risk premiums continuing to be injected and supporting oil prices to move higher. However, Middle Eastern export flows have already recovered to about 80% of pre-war levels. Saudi Arabian crude oil exports increased by 7.9% month-on-month in August. Russian diesel cargoes were sent to the United States, supply counterbalances limit the upside, and at the psychological level of $100, disagreements between bulls and bears intensify, so the main approach is to wait for a breakthrough. (2) Key focus: Geopolitical situation, inventory data, US dollar index. (3) Resistance: 101.00, 102.00, 103.00. (4) Support: 100.00, 99.00, 98.00.
