Iran War Fears Plunge Wall Street Into Correction

The market's decline reflects growing alarm over the Iran war's potential to disrupt the Persian Gulf's energy industry, leading to sustained high oil prices and global inflation. Brent crude climbed 3.4% to $105.32 per barrel, while benchmark U.S. crude rose 5.5% to $99.64 per barrel, significantly up from approximately $70 before the conflict.

President Donald Trump's repeated extensions of a deadline to "obliterate" Iran's power plants, intended to ease oil flow through the Strait of Hormuz, provided only temporary relief, as fighting continued and Iran showed no signs of de-escalation. Doug Beath, global equity strategist at Wells Fargo Investment Institute, stated that "diplomatic dissonance" dismayed investors, while Jim Bianco, president of Bianco Research, noted that only Iranian statements of progress would impact markets.

Strategists at Macquarie project oil prices could reach $200 per barrel if the war persists until June, exacerbating inflation and consumer confidence, which fell more than economists expected in March according to a University of Michigan survey. Big Tech stocks like Amazon, Meta Platforms, and Nvidia, alongside non-essential consumer companies such as Norwegian Cruise Line Holdings, Starbucks, and Chipotle Mexican Grill, experienced significant drops, contributing to the S&P 500 being 8.7% below its January high.

Treasury yields also rose, with the 10-year Treasury reaching 4.43%, up from 3.97% before the war, increasing mortgage and loan rates and slowing the economy.
