US equity markets surged to record levels on Tuesday, marking a powerful reversal as investors embraced a confluence of positive catalysts.

The broad-based rally was fueled by growing optimism that a diplomatic resolution is imminent regarding tensions in the Strait of Hormuz, alongside a wave of strong corporate earnings reports.

This sentiment shift has helped lift major indices, with the Dow Jones Industrial Average jumping more than 900 points in the session.

The market move reflects a significant repricing of geopolitical risk.

Earlier this month, Iran threatened forceful responses to tankers deviating from approved routes, deepening uncertainty around shipping costs and energy supplies. However, recent signals from US Treasury Secretary Scott Bessent suggesting an imminent deal have alleviated some of the pressure on trade routes.

This de-escalation narrative has provided a tailwind for equities, allowing investors to focus on fundamental drivers rather than geopolitical tail risks.

Corporate fundamentals are also supporting the rally.
