The informal ceasefire has broken down as Iran launches missile attacks on a U.S. military base in Jordan, causing oil prices to surge nearly 5%.

1. According to foreign media reports, U.S. officials revealed that Iran launched multiple ballistic missiles at a U.S. military base located inside Jordan. This marks the first missile attack by Iran against a U.S. base in the region since the United States suspended military strikes against Iran last Friday.2. The U.S. Central Command subsequently confirmed that the attack occurred at 5:45 p.m. Eastern Time on July 28 (5:45 a.m. Beijing Time on July 29). Iran attempted to carry out a surprise attack on U.S. forces stationed in the Middle East, but all incoming missiles were successfully intercepted. Central Command stated that U.S. troops have maintained a high level of vigilance and readiness at all times.3. This attack signifies the breakdown of the short-lived, informal ceasefire between the U.S. and Iran. As a result of this sudden event, the international crude oil market surged at the opening on Wednesday, with U.S. crude oil prices jumping over $2 in the short term, reaching a new two-day high of $83.25 per barrel and posting an intraday gain of nearly 5%.
