Stocks stumble amid worries about interest rates

NEW YORK >> Stocks tumbled on Wall Street Friday, leaving the S&P 500 with its biggest one-day loss in almost seven weeks, as worries deepen about a surge in interest rates and the U.S. central bank's efforts to fight inflation.

Several disappointing profit reports from companies also shook what's been the market's main pillar of support.

The S&P 500 sank 2.8% and marked its third losing week in a row. The Dow Jones Industrial Average slumped 2.8%, its biggest drop in 18 months, after briefly skidding more than 1,000 points. The Nasdaq also had its worst day in nearly seven weeks, closing 2.6% lower.

A day earlier, Wall Street seemed set for healthy gains for the week after American Airlines, Tesla and other big companies reported strong profits or better forecasts for future earnings than analysts expected. Such corporate optimism has helped stocks remain relatively resilient, even as worries swirl about the highest inflation in decades, the war in Ukraine and the coronavirus.

But markets buckled as the chair of the Federal Reserve indicated the central bank may indeed hike short-term interest rates by double the usual amount at upcoming meetings, starting in two weeks.

The Fed has already raised its key overnight rate once, the first such increase since 2018, as it aggressively removes the tremendous aid thrown at the economy through the pandemic. It's also preparing other moves to put upward pressure on longer-term rates.

By making it more expensive for businesses and households to borrow, the higher rates are meant to slow the economy, which should hopefully halt the worst inflation in generations. But they can also trigger a recession, all while putting downward pressure on most kinds of investments.
