In a day marked by escalating geopolitical tensions, oil prices surged to their highest levels in nearly four years while U.S. stock markets experienced declines. The movements, though significant, were less dramatic than the heated rhetoric emanating from both the United States and Iran as a critical deadline approached.
Market Movements Reflect War Anxiety
The S&P 500 slipped by 0.4% on Tuesday, with the Dow Jones Industrial Average dropping 169 points and the Nasdaq composite falling 0.5%. In contrast, the oil market saw sharper gains, with benchmark U.S. crude rising by 3% to reach $114.87 per barrel, a peak not seen since the summer of 2022 following Russia's invasion of Ukraine. Brent crude, the international standard, also increased by 1% to $110.82 per barrel.
Trump's Ultimatum and Iranian Response
With just hours remaining before President Donald Trump's latest deadline to bomb Iranian power plants if the Strait of Hormuz is not reopened, tensions reached a fever pitch. Trump threatened to destroy all of Iran's power plants and bridges if Tehran does not allow full traffic resumption in the strait, a crucial waterway through which a fifth of the world's oil transits in peacetime. In response, Iranian officials urged young people to form human chains to protect power plants, and U.S. airstrikes pounded Tehran on Tuesday.
World leaders and experts have warned that such destructive strikes could constitute war crimes, adding to the global unease. The Mizuho Bank research team in Singapore noted that Trump's actions represent "an escalation cycle that has now been extended several times since his first ultimatum in late March," highlighting the persistent deadlock in the conflict.
Economic and Corporate Developments
Oil prices have risen more than 70% since the U.S. and Israel launched attacks on Iran at the end of February, causing significant damage to the world economy and increasing pressure on Trump to resolve the standoff. Iran rejected the latest ceasefire proposal on Monday, instead demanding a permanent end to the war.
In corporate news, Bill Ackman's Pershing Square Capital Management offered to purchase Universal Music Group in a cash-and-stock transaction valued at approximately $64 billion. The deal would involve merging Universal Music with Pershing Square SPARC Holdings, with plans to base the new company in Nevada and move its stock listing from Amsterdam to the New York Stock Exchange. Shares of UMG rose 10% in Amsterdam following the announcement.
Global Stock Market Reactions
Global stock indexes showed mixed reactions to the tensions. In Europe, France's CAC 40 was up 0.3% at midday, while the German DAX slid 0.3% and Britain's FTSE 100 lost 0.2%. In Asia, Japan's Nikkei 225 gained less than 0.1% to close at 53,429.56, Australia's S&P/ASX 200 rose 1.7% to 8,728.80, South Korea's Kospi advanced 0.8% to 5,494.78, and the Shanghai Composite edged up 0.3% to 3,890.16. Trading was closed in Hong Kong for a holiday.
Treasury yields held mostly steady amid the uncertainty, reflecting a cautious investor sentiment as the world watches the unfolding crisis with bated breath.
