U.S. equities closed lower on Tuesday, April 21, 2026, as renewed geopolitical tensions and a hawkish stance from a key Federal Reserve nominee weighed heavily on investor sentiment. The S&P 500 posted a decline of 45.13 points (-0.63%) to close at 7064.01. The tech-heavy NASDAQ Composite also retreated, shedding 144.43 points (-0.59%) to end the day at 24259.97. Similarly, the Dow Jones Industrial Average fell 293.18 points (-0.59%), settling at 49149.38.

Key market drivers included:

• Escalating Geopolitical Concerns: Markets reacted negatively to reports of Iran refusing to participate in a second round of peace talks with the U.S., exacerbating fears surrounding the conflict and its potential impact on global energy supplies. The Strait of Hormuz remained under blockade, fueling uncertainty. However, positive news emerged after market close, with President Trump announcing an extension of the ceasefire with Iran until talks conclude, which subsequently boosted U.S. stock futures for Wednesday's trading.
• Hawkish Fed Tone: Kevin Warsh, President Trump's nominee for Federal Reserve Chair, testified before the Senate Banking Committee, advocating for a new inflation framework and the shrinking of the Fed's balance sheet. His testimony was widely perceived as hawkish, adding to market caution.
• Soaring Oil Prices: Amid the geopolitical uncertainty, crude oil prices surged, with West Texas Intermediate (WTI) trading above $90 a barrel and Brent crude nearing $98. The ongoing tensions and the blockade of the Strait of Hormuz were primary catalysts for the significant rise.
• Strong Retail Sales: On the economic front, U.S. retail sales recorded their largest monthly increase in a year, suggesting robust consumer spending despite rising gasoline prices. This data further reinforced expectations that the Federal Reserve might maintain current interest rates for longer.

Sector performance was mixed, but with a clear divergence. The Energy sector emerged as the top performer, gaining 1.31% as rising oil and gas prices bolstered sentiment for related stocks like APA Corp, Halliburton, and Occidental Petroleum. Conversely, the Real Estate sector led the downside, declining by 1.94%, with real estate investment trusts (REITs) suffering from concerns that higher oil prices could stoke inflation and lead to elevated mortgage rates. The Communication Services, Health Care, and Utilities sectors also experienced declines.
