US crude oil: Rising in a fluctuation, buy on dips

(1) Analysis Reason: WTI crude oil continues to strengthen, approaching the upper edge of the range. Houthi attacks on Saudi facilities and the attack on an oil tanker in the Strait of Hormuz maintain a supply risk premium, while diplomatic contact between the US and Iran limits the upward slope. Ongoing EIA inventory reduction and unchanged OPEC+ quotas provide bottom support, but a strong US dollar and high shipping costs are suppressing refinery profits. In the short term, prices are expected to remain in a volatile uptrend.(2) Key Focus: Geopolitical situation, inventory data, US Dollar Index(3) Resistance: 105.00, 106.00, 106.50(4) Support: 103.00, 102.00, 101.00
