U.S. stocks fall sharply as Fed holds rates; oil surges on Iran tensions

Major U.S. equity indexes declined 1.5–2.2% following the Fed's rate hold and dissenting votes, signaling policy uncertainty and persistent inflation concerns. Rising Treasury yields (10-year at 4.68%, 30-year at 5.2%—highest since 2007) indicate bond market skepticism of rate control. Oil prices jumped 6.5–7.9% following Trump administration statements on escalated military responses to Iranian attacks, raising energy cost pressures on consumer and industrial spending. Tech and semiconductor stocks fell ahead of earnings, and eight of eleven S&P 500 sectors declined; these moves directly affect corporate profitability, consumer purchasing power, and portfolio valuations across retirement and institutional funds.
