0:00 / 0:30

Major Wall Street indexes declined sharply as surging Treasury yields and escalating crude oil prices triggered aggressive profit-taking across high-valuation technology stocks. The benchmark 10-year Treasury yield climbed, increasing corporate borrowing costs and making fixed-income assets more competitive against equities. Simultaneously, rising energy costs intensified broader macroeconomic concerns regarding persistent inflation. High-growth and technology sectors bore the brunt of the sell-off as discount rates shifted upward, prompting institutional investors to de-risk portfolios. Market analysts noted that the combination of tighter monetary conditions and higher energy prices created a challenging environment for corporate valuations. The Dow Jones Industrial Average, S&P 500, and Nasdaq composite all finished lower in response to the macroeconomic pressures. Trading volume increased across major exchanges as market participants adjusted positions ahead of upcoming economic data releases and central bank commentary.
