Wall Street Rallies as US-Iran Deal Triggers Oil Slump and AI Surge

Global financial markets witnessed a massive surge on Monday following news of a tentative agreement between the United States and Iran to extend their ceasefire and reopen the Strait of Hormuz. This geopolitical breakthrough has revitalised investor sentiment, driving major indices higher and cooling energy prices significantly.

Oil Prices Tumble on Geopolitical De-escalation

The most immediate impact of the US-Iran deal was felt in the energy sector. Brent crude oil prices plummeted by 4.8% to $83.18 a barrel, returning to levels last seen in early March. While prices remain above the pre-conflict level of $70, they have retreated sharply from the $100-plus peaks observed just weeks ago.

The reopening of the Strait of Hormuz is expected to ease inflationary pressures on food, fuel, and fertiliser. While Iran has confirmed the agreement, formal signing is expected to take place this Friday in Switzerland. Although industry observers warn that normalizing energy flows could take months, the immediate reduction in geopolitical risk has provided a significant cushion for global markets.

Travel and AI Sectors Lead the Wall Street Rally

The relief in energy costs provided an immediate boost to capital-intensive sectors. Travel and hospitality stocks saw substantial gains, with American Airlines climbing 7%, Carnival advancing 5.7%, and United Airlines rising 5.2%.

Simultaneously, the technology sector, particularly Artificial Intelligence (AI), reclaimed its momentum after recent volatility. Micron Technology surged 7.8%, while Advanced Micro Devices (AMD) rose 7%. Nvidia, a heavyweight in the S&P 500, climbed 2.7%, providing a massive lift to the broader index.

A standout performer was SpaceX, which climbed 5.4% in its second day of trading. With a market valuation exceeding $2.1 trillion, SpaceX has now surpassed the combined value of Exxon Mobil, Bank of America, and Coca-Cola, signaling robust investor appetite for AI and space-tech integration.

Shifting Expectations for Federal Reserve Policy

The drop in oil prices has also recalibrated expectations for US monetary policy. As energy-driven inflation fears recede, Treasury yields have eased, with the 10-year Treasury note falling to 4.45% from 4.48%.

Before the deal, markets were pricing in a high probability of interest rate hikes. However, according to CME Group data, traders have now slashed the probability of a rate increase this year from 71% to just 55%. This shift comes as investors look ahead to the US Federal Reserve's upcoming policy decision under new chair Kevin Warsh. While President Trump has advocated for lower rates, the market's current focus is on whether the easing inflationary outlook will allow the Fed to maintain status quo.

Global Market Synchronization

The rally was not confined to the US. Asian markets saw historic gains, with Japan's Nikkei 225 surging 5% to a record high. South Korea's Kospi also climbed 5.2%, bolstered by AI-related giants like Samsung Electronics. Analysts suggest that foreign investor inflows are driving these gains as global tensions in the Middle East appear to subside.
