Markets brace for Trump's Iran deadline, oil risk looms, Dow down 250 points

Global markets have entered a period of heightened uncertainty as investors brace for the outcome of a deadline set by US President Donald Trump for Iran to reopen the Strait of Hormuz, a critical artery for global oil flows.

Iran has shown no indication of complying with the demand by the Tuesday deadline, raising the risk of further escalation.

According to reports, Tehran has also cut off direct diplomacy with the United States, adding to concerns about the trajectory of the conflict.

“Markets are dealing with a somewhat binary situation as they try to position themselves ahead of a deadline which will either see a sudden resolution or a swift escalation,” said David Morrison, senior market analyst at Trade Nation in a Reuters report.

On Tuesday, the benchmark S&P 500 fell nearly 1%, Dow Jones declined 255 points or 0.55% while oil edged higher, and both the dollar and gold slipped, reflecting the uncertainty across asset classes.

Military escalation could drive oil higher, equities lower

A prolonged conflict and disruptions to oil supply could have significant consequences for global markets.

Citigroup estimates that Brent crude prices could rise to around $130 per barrel under a severe escalation scenario.

Equities would likely decline, particularly interest rate-sensitive and cyclical stocks, as investors price in slower growth and higher inflation.

Travel-related stocks such as American Airlines and Carnival Corporation are seen as particularly vulnerable due to rising fuel costs and weakening demand.

By contrast, companies positioned at the intersection of artificial intelligence and defense, including Palantir and CrowdStrike, could benefit if volatility persists and geopolitical tensions intensify.

The US dollar has strengthened amid safe-haven demand. “If expectations shift to high-for-longer oil prices, USD could strengthen further, as this may magnify the inflation and output pressures faced by energy importers,” said Steve Englander.

A stronger dollar could also pressure the Japanese yen, increasing the likelihood of intervention by the Bank of Japan if the currency weakens further.

Peace deal could trigger broad market rally

A de-escalation scenario would likely reverse many of the recent market trends.

The S&P 500 has already rebounded about 4% from its late-March lows on hopes of a resolution.

“Look for bond yields to decline, oil/energy prices to see a significant decline, USD to sell off, credit spreads to tighten, and equities to rip,” JP Morgan analysts said.

In this scenario, sectors that have benefited from higher oil prices and geopolitical risk—such as defense, fertilizer, and energy—could see gains unwind.

Meanwhile, beaten-down airline and cruise stocks may recover as fuel costs decline and demand stabilizes.

A cooling of tensions could also shift expectations for monetary policy, with markets potentially revisiting bets on interest rate cuts as inflation pressures ease.

Deadline extension may support cautious risk-on mood

A further extension of the deadline could offer short-term relief to markets, as investors interpret it as a sign that negotiations are progressing.

“Realistically, though, another TACO moment for Trump is more likely than Iran backing down and this is probably what's preventing markets from going into meltdown,” said Raffi Boyadjian.

However, analysts caution that any optimism may be limited. Markets could move sideways as uncertainty persists, with JP Morgan favoring a market-neutral stance amid ongoing risks to shipping routes and energy supply.

Brent crude is expected to remain supported around $110 per barrel, while gold prices could hold steady as investors maintain hedging positions despite recent declines.

As the deadline approaches, markets remain finely balanced between escalation and resolution, with significant implications for global equities, commodities, and currencies.
