Mideast War Fears Rock Oil Markets

The conflict in the Middle East, which included the death of Iran's Supreme Leader, Ayatollah Ali Khamenei, has entered its third day.

President Donald Trump on Sunday indicated that the current U.S. military strikes against Iran could continue for “four to five weeks,” if necessary, and indicated there could be more casualties in days to come. Meanwhile, Iran’s security chief, Ali Larijani, rejected talks with Washington and accused Trump of driving the region into chaos.

Amid this, the global energy markets turned highly volatile on Monday as crude prices jumped to their highest levels since early 2025, following escalating military conflict. Goldman Sachs estimates an $18-per-barrel risk premium, about 25% of current prices, amid growing fears of a prolonged Strait of Hormuz blockade.
