Oil rises and Asian stocks fall after Trump says US will hit Iran hard

Oil prices surged over four percent, and Asian stock markets declined sharply after former U.S. President Donald Trump announced the United States would "hit Iran very hard" and "finish the job" in his first national address since what he termed the "Iran war began." This market reaction is driven by the immediate perception of a significant escalation in US-Iran geopolitical tensions, which often translates into increased uncertainty and risk aversion among investors. The 'Why' for oil specifically relates to the Middle East being a critical crude oil production hub and home to the strategically vital Strait of Hormuz; any threat to stability in this region directly jeopardizes global oil supply, prompting prices to rise sharply. Concurrently, heightened global instability typically causes investors to divest from risk-sensitive assets like equities, particularly in export-dependent Asian markets, in favor of safer investments, leading to widespread stock market declines.
