Global markets showed mixed reactions on Monday following airstrikes by the United States and retaliatory actions from Iran. In early European trading, Germany’s DAX rose 0.2% to 25,105.55, while France’s CAC 40 increased 0.1% to 8,347.26. The UK’s FTSE 100 also edged up 0.1% to 10,506.86.
U.S. stock futures displayed mixed performance; the S&P 500 futures fell by 0.3%, while the Dow remained largely unchanged. The Nasdaq Composite futures decreased by 0.9%.
Brent crude oil experienced a spike of nearly 5% early Monday before retreating. By early morning in Europe, Brent crude was up 2.3% at $77.72 per barrel, while the U.S. benchmark crude rose 2.1% to $72.92 per barrel.
Both crude prices had recently fallen back to pre-conflict levels after a provisional agreement between the U.S. and Iran ended tensions and allowed oil shipments through the Strait of Hormuz. This stability shifted after the U.S. launched a series of attacks on Iran in response to an Iranian assault on a container ship, which caused a fire and left a crew member missing over the weekend. Iran retaliated with strikes across the Middle East.
The renewed conflict is raising questions about global oil flow, energy prices, and inflation.
In Asian markets, Tokyo’s Nikkei 225 dropped 1.9% to 67,242.73, and Seoul’s Kospi fell sharply by 9% to 6,806.93, reaching its lowest level since May. South Korea’s SK Hynix saw its stock plummet 15.4% in Seoul, while competitor Samsung Electronics fell 10.7%.
Elsewhere in Asia, the Hang Seng in Hong Kong rose 0.2% to 24,212.36, while Shanghai’s Composite Index dropped 2.1% to 3,913.79. In Australia, the S&P/ASX 200 remained relatively steady at 8,808.50.
U.S. stocks showed slight increases on Friday as investors maintained interest in companies associated with artificial intelligence. The S&P 500 and Dow Jones Industrial Average each climbed 0.4% and 0.3% respectively, while the Nasdaq Composite rose 0.3%.
SK Hynix had a notable debut on Wall Street with its shares soaring after raising approximately $26.5 billion through the sale of American Depositary Shares at $149 each. The company’s stock had surged by over 600% in the past year due to enthusiasm for AI, driven by growing demand for computer memory. However, concerns are rising that the high valuations of AI-linked stocks may be unsupported by actual economic gains.
Swissquote’s Ipek Ozkardeskaya commented on the stock’s surge, highlighting the market perception that AI demand could keep the memory chip sector in a perpetual boom phase. Nonetheless, technological advancements or investment slowdowns might lead to oversupply.
Investors are closely monitoring corporate earnings reports to determine if companies’ profits are rising fast enough to justify the high stock prices. Upcoming reports from major U.S. banks on Tuesday, including Bank of America, Citigroup, JPMorgan Chase, Goldman Sachs, and Wells Fargo, will be crucial.
The conflict with Iran raises concerns about energy costs and overall inflation. High bond yields continue to pressure global financial markets as expensive oil and inflation could push the Federal Reserve and other central banks to increase interest rates. Although higher rates can curb inflation, they also slow the economy and negatively impact investment prices.
In other trading early Monday, the U.S. dollar rose to 162.01 Japanese yen from 161.72 yen. Meanwhile, the euro increased to $1.1435 from $1.1408.
