U.S. stocks took a sharp downturn on Monday, with the Dow Jones Industrial Average falling nearly 450 points as escalating geopolitical tensions in the Middle East sent oil prices soaring. The Dow dropped 0.90%, the S&P 500 declined 0.44%, and the Nasdaq Composite slipped 0.39%. The selloff came as Brent crude surged 5.31% to $113.91 per barrel, according to Reuters market data, driven by fears of disruptions near the strategic Strait of Hormuz.
Geopolitical Jitters Spark Risk-Off Mood
The market's move caught many investors off guard, as equities had been riding high on upbeat earnings and expectations of stable energy markets. However, reports from Iranian state-affiliated outlets claiming a missile strike on a U.S. vessel near the strait—denied by U.S. military officials—and the UAE's confirmation of intercepting Iranian missiles triggered a swift shift to risk aversion. The Pentagon later reported that two American-flagged merchant vessels passed through the strait without incident, but the damage to sentiment had already been done.
Barclays became the latest major brokerage to forecast no Federal Reserve rate cuts in 2026, arguing that sustained higher oil prices could push inflation higher and stunt economic growth. This added to the pressure, especially after the S&P 500 and Nasdaq had closed at record highs on Friday, buoyed by strong tech earnings.
Market Impact and Sector Performance
By midday in New York, the Dow had tumbled 429.90 points, with the S&P 500 losing 32.63 points and the Nasdaq sliding 101.96 points. Only one of the 11 S&P 500 sectors managed to stay in positive territory. The CBOE Volatility Index (VIX) climbed to 18.39, signaling heightened expectations for future stock swings.
Brock Weimer, investment strategy analyst at Edward Jones, noted that oil staying above $100 a barrel has begun shifting last year's tax cuts from acting as stimulus to serving more as a 'shock absorber.' Adam Turnquist, chief technical strategist at LPL Financial, cautioned that seasonal trends are not a reliable guide, but if oil prices ease and the Middle East remains relatively quiet, equities could get a lift—assuming earnings don't disappoint.
Corporate Moves: Amazon, GameStop, and Travel Stocks
Beyond the macro picture, several corporate developments drove stock-specific action. Amazon (AMZN) announced it is opening its supply-chain network to outside businesses, directly competing with delivery giants UPS (UPS) and FedEx (FDX). Shares of both rivals tumbled on the news. Equisights Research CEO Parth Talsania described Amazon's move as a 'structural warning shot' in delivery routes packed with e-commerce.
In deal news, GameStop (GME) made headlines with a roughly $56 billion cash-and-stock bid for eBay (EBAY). CEO Ryan Cohen indicated he is prepared to take the proposal directly to shareholders if eBay's board rejects it, telling the Wall Street Journal he believes eBay has the potential to be a 'legit competitor to Amazon.' GameStop shares slipped, while eBay shares climbed on the bid.
Travel and cruise stocks also faced headwinds. Norwegian Cruise Line Holdings (NCLH) trimmed its 2026 profit outlook, citing spiking fuel costs from Middle East tensions and softer demand. Carnival (CCL) and Royal Caribbean (RCL) have also warned about fuel price pressures.
Berkshire Hathaway and Fund Flows
Berkshire Hathaway (BRK.B) reported a rise in first-quarter operating profit but flagged economic uncertainty as a drag on its consumer-focused businesses. The conglomerate's cash pile ballooned to a record $380.2 billion, and it sold more stocks than it bought for the 14th consecutive quarter.
Fund flows showed growing caution. U.S. equity funds logged just $911 million in inflows for the week ended April 29—the least since March 18—as traders eyed crude prices and the Fed. Technology funds continued to attract money, while healthcare funds saw outflows.
Outlook: Stagflation Fears and Earnings Season
There is a risk that oil remains elevated long enough to snarl both inflation and corporate profits. Mark Malek, chief investment officer at Siebert Financial, called the Strait of Hormuz standoff the 'wild card,' noting that a breakthrough could ease energy prices, but prolonged disruption raises the threat of stagflation—slower growth paired with hotter inflation.
Investors are now bracing for a packed earnings slate, with reports due from AMD (AMD), Super Micro Computer (SMCI), Palantir (PLTR), Disney (DIS), and McDonald's (MCD). April's payrolls report is also due on Friday. Chris Larkin of E*TRADE from Morgan Stanley noted that market sentiment in the short run depends on 'sidestepping negative surprises' out of the Middle East, leaving earnings to set the tone.
