The global financial markets experienced heightened volatility on Tuesday as US President Donald Trump issued a stark ultimatum to Iran regarding the reopening of the Strait of Hormuz, a critical chokepoint for nearly 20% of global oil supply [1][2]. Trump threatened severe consequences, including potential strikes on Iran’s energy and civilian infrastructure, and hinted at the possibility of nuclear escalation, stating, 'A whole civilization will die tonight, never to be brought back again. I don’t want that to happen, but it probably will' [1][3]. The deadline for Iran to comply was set for 8:00 p.m. Eastern Time (00:00 GMT Wednesday) [1][2].
Oil prices responded sharply to the geopolitical tension. West Texas Intermediate (WTI) crude traded around $104.30 earlier in the day [1], but surged 3% to above $116 per barrel as the deadline approached, while Brent crude advanced above $110 [2]. The US Energy Information Administration reported that production shut-ins reached approximately 7.5 million barrels per day in March and could rise to over 9 million barrels per day in April, underscoring the supply tightness already affecting global markets [1]. The EIA projects WTI crude oil prices will average $87 per barrel in 2026, with global oil demand growth slowing to 0.6 million barrels per day in 2026, down from 1.2 million barrels per day in the previous month’s report [1].
Equity markets reacted negatively to the escalating crisis. The Dow Jones Industrial Average (DJIA) dropped around 380 points, or 0.8%, breaking a four-session winning streak, while the S&P 500 fell 0.9% and the Nasdaq Composite shed 1.3% [2]. Losses accelerated after reports that Iran had stopped negotiating a truce with the US, and US forces carried out overnight strikes on Kharg Island, Iran's primary oil export terminal [2]. Despite some reports of progress in negotiations, US and Israeli officials indicated that a ceasefire deal before the deadline was unlikely [1][2].
Currency markets also reflected the heightened risk, with USD/JPY trading near 159.95 and showing a mildly bullish bias as investors sought safety amid the geopolitical uncertainty [3]. Technical analysis indicated steady upside momentum for USD/JPY, with resistance at 159.95 and the next upside level at 160.03 [3].
In contrast to the broader market selloff, Broadcom (AVGO) rose 3% after announcing expanded artificial intelligence partnerships with Google (GOOG) and Anthropic. Broadcom disclosed a long-term agreement to supply next-generation TPUs for Google through 2031, and Anthropic will access 3.5 gigawatts of TPU-based compute capacity starting in 2027. Anthropic's revenue run rate has topped $30 billion, with over 1,000 business customers spending more than $1 million annually [2].
CONCLUSION
The looming US-Iran deadline and threats of military escalation have driven oil prices sharply higher and triggered broad declines in equity markets, with risk sentiment dominated by geopolitical headlines. Supply disruptions through the Strait of Hormuz and breakdowns in negotiation have compounded market anxiety, while select technology stocks like Broadcom bucked the trend on positive partnership news. Unless tensions de-escalate meaningfully, oil prices and market volatility are likely to remain elevated.
