International oil prices show a volatile upward trend. Recently, international oil prices hit a two-month high, with WTI New York crude rising as high as $66.76 per barrel and Brent crude rising as high as $69.95 per barrel.

   In this pricing cycle, Colonial Pipeline, the largest fuel pipeline operator in the United States, has been subjected to a cyber attack. The attack forced the operator to close a key transportation pipeline. The pipeline accounts for 45% of the fuel supply on the east coast of the United States. As a result, the United States declared a state of emergency in 17 states and Washington, D.C. In addition, the recent geopolitical turmoil in the Middle East, the conflict between Palestine and Israel continued to occur, the two sides rockets, interceptors hit and exploded in the night sky.This makes the international market worried about oil supply in the Middle East.
