NEW YORK -- Stocks tumbled to their worst day in more than two years Tuesday, knocking the Dow Jones Industrial Average down more than 1,250 points, following Wall Street's humbling realization that inflation is not slowing as much as hoped.
The S&P 500 sank 4.3%, its biggest drop since June 2020. The Dow fell 3.9% and the Nasdaq composite closed 5.2% lower. The sell-off ended a four-day winning streak for the major stock indexes and erased an early rally in European markets.
Bond prices also fell sharply, sending their yields higher, after a report showed inflation decelerated only to 8.3% in August, instead of the 8.1% economists expected.
The hotter-than-expected reading has traders bracing for the Federal Reserve to ultimately raise interest rates even higher than expected to combat inflation, with all the risks for the economy that entails. Fears about higher rates sent prices dropping for everything from gold to cryptocurrencies to crude oil.
"Right now, it's not the journey that's a worry so much as the destination," said Brian Jacobsen, senior investment strategist at Allspring Global Investments. "If the Fed wants to hike and hold, the big question is at what level."
The S&P 500 fell 177.72 points to 3,932.69. The drop didn't quite knock out its gains over the past four days. The index is now down 17.5% so far this year.
The Dow lost 1,276.37 points to 31,104.97, and the Nasdaq dropped 632.84 points to 11,633.57. Big tech stocks swooned more than the rest of the market, as all 11 sectors that make up the S&P 500 sank.
Most of Wall Street came into the day thinking the Fed would hike its key short-term rate by a hefty three-quarters of a percentage point at its meeting next week. But the hope was that inflation was in the midst of quickly falling back to more normal levels after peaking in June at 9.1%.
The thinking was that such a slowdown would let the Fed downshift the size of its rate hikes through the end of this year and then potentially hold steady through early 2023.
Tuesday's report dashed some of those hopes.
"This piece of data just hammered home that the Fed isn't going to have the data to do anything differently than continue on their rate-raising path for longer," said Tom Martin, senior portfolio manager with Globalt Investments. "It just increases the chance of an actual recession."
Many of the data points within the inflation report were worse than economists expected, including some the Fed pays particular attention to, such as inflation outside of food and energy prices.
Markets honed in on a 0.6% rise in such prices during August from July, double what economists expected, said Gargi Chaudhuri, head of investment strategy at iShares.
The inflation figures were so much worse than expected that traders now see a one-in-three chance for a rate hike of a full percentage point by the Fed next week. That would be quadruple the usual move, and no one in the futures market was predicting such a hike a day earlier.
The Fed has already raised its benchmark interest rate four times this year, with the last two increases by three-quarters of a percentage point. The federal funds rate is currently in a range of 2.25% to 2.50%.
"The Fed can't let inflation persist. You have to do whatever is necessary to stop prices from going up," said Russell Evans, managing principal at Avitas Wealth Management. "This indicates the Fed still has a lot of work to do to bring inflation down."
Higher rates hurt the economy by making it more expensive to buy a house, a car or anything else bought on credit. Mortgage rates have already hit their highest level since 2008, creating pain for the housing industry. The hope is that the Fed can pull off the tightrope walk of slowing the economy enough to snuff out high inflation, but not so much that it creates a painful recession.
Tuesday's data puts hopes for such a "soft landing" under more threat. In the meantime, higher rates also push down on prices for stocks, bonds and other investments.
Investments seen as the most expensive or the riskiest are the ones hardest hit by higher rates. Bitcoin tumbled 9.4%.
In the stock market, all but six of the stocks in the S&P 500 fell. Technology and other high-growth companies fell more than the rest of the market because they're seen as most at risk from higher rates.
To be sure, the losses only return the S&P 500 close to where it was before its recent winning streak. That run was built on hopes that Tuesday's inflation report would show a more comforting slowdown. The ensuing wipeout fits what's become a pattern on Wall Street this year: Stocks fall on worries about inflation, turn higher on hopes the Fed may ease up on rates and then fall again when data undercuts those hopes.
Treasury yields leaped immediately on expectations for a more aggressive Fed. The yield on the two-year Treasury, which tends to track expectations for Fed actions, soared to 3.74% from 3.57% late Monday. The 10-year yield, which helps dictate where mortgages and rates for other loans are heading, rose to 3.42% from 3.36%.
Expectations for a more aggressive Fed also helped the dollar add to its already strong gains for this year. The dollar has been surging against other currencies in large part because the Fed has been hiking rates faster and by bigger margins than many other central banks.
