NEW YORK (AP) -- Wall Street rallied Wednesday following the Federal Reserve's sharpest hike to interest rates since 1994, and its later assurance that such mega-hikes would not be common.
The S&P 500 climbed 54.51, or 1.5%, to 3,789.99 after whipping through roller-coaster trading immediately following the Fed's announcement. In equally topsy-turvy trading, Treasury yields eased in the bond market after Chair Jerome Powell seemed to soothe the market's fears about an overly aggressive Fed by implying more modest rate increases may be coming later this year.
The Dow Jones Industrial Average swung between a gain of 530 points and a loss of nearly 180 before finishing with a gain of 303.70, or 1%, to close at 30,668.53. The Nasdaq composite jumped 270.81, or 2.5%, to 11,099.15.
The market's ebullience was a sharp turnaround from the worldwide rout that has dominated much of this year, which forced the S&P 500 into a bear market earlier this week. The fear has been that high inflation will push the Fed and other central banks to clamp the brakes too hard on the economy and create a recession.
Some analysts cautioned Wednesday's rally could ultimately be short-lived given how deeply and broadly high inflation has seeped into the economy and how unsettlingly uncertain the future path is.
"Chair Powell painted as rosy a picture as could be painted, and to achieve that picture that he is laying out, that pathway, a lot has to go right," said Yung-Yu Ma, chief investment strategist at BMO Wealth Management. "It's a challenging path, and he acknowledged that."
The Fed on Wednesday hiked its key short-term interest rate by three-quarters of a percentage point, triple the usual move. Powell said the Fed may consider another increase that big at its next meeting in July, but he also said such a hike is "an unusually large one" and not to expect it to be common.
The Fed is "not trying to induce a recession now, let's be clear about that," Powell said. He said Wednesday's big increase was about the Fed speeding up the move to get interest rates back to normal, calling it "front-end loading."
"He's making it extremely clear to the market, to U.S. consumers, that the Fed takes this seriously and is doing whatever it takes to take inflation down and maintain price stability," said Quincy Krosby, chief equity strategist for LPL Financial.
All kinds of investments, from bonds to bitcoin, have tumbled this year as high inflation forces central banks to swiftly remove supports propped underneath markets early in the pandemic.
Even if central banks pull off the delicate trick of slowing the economy just enough to stamp out inflation, without a recession, higher interest rates push down on prices for investments regardless. The hardest-hit have been the investments that soared the most in the easy-money era of ultralow interest rates, including high-growth technology stocks and cryptocurrencies.
Treasury yields this week shot to their highest levels in more than a decade on expectations for a more aggressive Fed, though they eased Wednesday following Powell's comments. A disappointing report showing that sales at U.S. retailers unexpectedly slumped in May from April contributed. So did a weaker-than-expected report on manufacturing in New York state.
The economy is still largely holding up amid a red-hot job market, but it has shown some signs of distress recently. A preliminary reading on consumer sentiment last week, for example, sank to its lowest reading on record due in large part to high gasoline prices.
The two-year Treasury yield fell to 3.23% from 3.45% late Tuesday, with the biggest move happening after Powell said not to expect 0.75 percentage point rate hikes to be common. The yield on the 10-year Treasury pulled back to 3.31% from 3.48%.
"The bond market right now is driving the broader market and that will continue," said Jay Hatfield, CEO of Infrastructure Capital Advisors.
Cryptocurrency prices continued to sink, and bitcoin dropped as low as $20,087.90, nearly 71% below its record of $68,990.90 set late last year. It was down 1.7% at $21,592 in afternoon trading, according to CoinDesk.
Its tumble has worsened this year as investors ramp up their expectations for how aggressively the Fed will move on interest rates.
Powell said Wednesday the Fed is moving "expeditiously" to get interest rates closer to normal levels after last week's stunning report that showed inflation at the consumer level unexpectedly accelerated last month.
It dashed hopes on Wall Street that inflation may have already peaked. The Fed has gotten criticism for moving too slowly earlier to rein in inflation. Other central banks around the world are also raising interest rates, adding to the pressure.
The war in Ukraine has helped send prices for oil soaring because the region is a major producer of energy. COVID infections in China, meanwhile, have led to the closure of factories and disrupted supply chains.
It all helped pull the S&P 500 down more than 20% from its record set in early January, putting Wall Street into what investors call a bear market.
Stocks also rose in Europe and parts of Asia Wednesday. Germany's DAX returned 1.4%, and the French CAC 40 rose 1.3% after the European Central Bank called an unscheduled meeting to address worries that rising interest rates will cause turmoil in the continent's bond market. The central bank did not give a detailed plan, but it said it would act if needed against "fragmentation" as yields for some European countries' bonds rise much more than for others.
Stocks in Shanghai gained 0.5% after government data showed Chinese factory activity rebounded in May as anti-virus controls that shut down businesses in Shanghai and other industrial centers eased.
