Iran Conflict Reaches 11 Weeks as Oil Prices Surge, Markets React

The conflict involving Iran has now stretched into its 11th week, lasting more than double the timeframe initially anticipated when President Donald Trump first authorized military action against the nation.

Hopes for a peaceful resolution that emerged last week were dashed over the weekend after Trump characterized Iran’s latest diplomatic response as “totally unacceptable.”

The ongoing standoff centers around Tehran’s nuclear program and its grip on the Strait of Hormuz, a critical waterway that remains largely closed to oil tankers and commercial vessels.

Global oil markets reacted sharply to Trump’s overnight statement, with prices spiking almost 5% before moderating slightly. Brent crude was trading around $104 per barrel, putting pressure on stock markets that had been performing strongly.

Despite energy sector concerns, the artificial intelligence boom and semiconductor rally continue to capture investor attention. South Korea’s technology-focused KOSPI index demonstrated this trend with a more than 4% surge on Monday.

U.S. stock futures showed little movement in early Monday trading, following another week of record highs for the S&P 500. Friday’s April employment data reinforced market optimism, joining other labor indicators that suggest the conflict hasn’t significantly impacted job growth yet.

However, employment effects may emerge with a delay, and elevated gasoline prices could eventually affect consumer spending.

Chinese stock markets gained ground ahead of this week’s scheduled meeting between Trump and Chinese President Xi Jinping, set to begin Thursday. The energy crisis has pushed Chinese producer and consumer prices higher than expected, potentially complicating the diplomatic discussions.

Treasury Secretary Scott Bessent is traveling to Tokyo today for discussions with Japanese government officials.

In the United Kingdom, Prime Minister Keir Starmer faces mounting pressure from his Labour Party colleagues following disappointing local election results. Despite weekend speculation about a potential leadership challenge, Starmer stated he would not resign and delivered remarks Monday intended to rally party support.

This week’s domestic economic calendar includes existing home sales figures for Monday, with April inflation data taking center stage Tuesday. The Senate may also vote Monday on Kevin Warsh’s nomination as the next Federal Reserve Chair, as current Chair Jerome Powell’s tenure ends Friday.

Major corporate earnings reports this week include technology companies Cisco and Applied Materials.

Chinese export activity accelerated in April as manufacturers worked to fulfill orders from artificial intelligence companies and other businesses stockpiling materials amid concerns that the Iran situation could drive global supply costs higher.

China’s trade surplus with the United States has expanded to $87.7 billion this year, a figure that will likely feature prominently in next week’s Trump-Xi summit discussions aimed at extending last year’s trade agreement.

Today’s key economic releases include U.S. existing home sales data and the Conference Board Employment Trends Index, both scheduled for 10 a.m. Eastern. A three-year Treasury note auction is set for 1 p.m. Eastern.
