NEW YORK (AP) -- Wall Street shuddered Friday, and stocks tumbled after getting hammered by data showing inflation is getting worse, not better, as investors had been hoping.
The S&P 500 was 2% lower in the first half hour of trading, while moves in the bond market indicated investors' concerns are building about a possible recession. The Dow Jones Industrial Average was down 611 points, or 1.9%, at 31,661 as of 9:55 a.m. Eastern time, and the Nasdaq composite was 2.4% lower.
Wall Street came into Friday hoping a highly anticipated report on the consumer price index would show the worst inflation in generations slowed a touch last month. Instead, the U.S. government said inflation accelerated to 8.6% in May from 8.3% a month before.
The Federal Reserve has already begun raising interest rates and making other moves to slow the economy, in hopes of forcing down inflation. Wall Street took Friday's reading to mean the Fed's foot will remain firmly on the brakes for the economy, dashing hopes that it may take a pause later this year.
The growing expectation in markets is for the Fed to raise its key short-term interest rate by half a percentage point at each of its next three meetings, beginning next week. That third one in September had been up for debate among investors in recent weeks. The Fed has raised rates by that degree only once since 2000, last month.
"Inflation is hot, hot, hot," said Brian Jacobsen, senior investment strategist at Allspring Global Investments. "Basically, everything was up. No relief is in sight, but a lot can change between now and September. Nobody knows what the Fed will do in a few months including the Fed."
A stock's price rises and falls on two things, essentially: how much profit a company produces and how much an investor is willing to pay for it. The Fed's moves on interest rates heavily influence that second part.
Since early in the pandemic, record-low interest rates engineered by the Fed and other central banks encouraged investors to pay higher prices for investments. Now "easy mode" is abruptly and forcefully getting switched off.
Not only that, too-aggressive rate hikes by the Fed could ultimately force the economy into a recession. Higher interest rates make borrowing more expensive, which drags on spending and investments by households and companies.
The two-year Treasury yield zoomed to 2.94% following the inflation report, after touching its highest level since 2018. It's up from 2.83% late Thursday.
The 10-year yield was also up, but more modestly than the two-year yield, which is more influenced by expectations for Fed movements. The 10-year yield climbed to 3.10% from 3.04%.
The narrowing gap between those two yields is a signal that investors in the bond market are more concerned about economic growth. Usually, the gap is wide, with 10-year yields higher because they require investors lock away their dollars for longer.
If the two-year yield rises above the 10-year yield, some investors see that as a red flag warning of a recession hitting in a year or two.
"A higher-than-expected CPI number seals the deal on investors' fears," Mike Loewengart, managing director at E-Trade from Morgan Stanley, wrote in a research note. "And though consumers may be experiencing high prices in their day-to-day, especially at the pump, it's disappointing to see that we don't have a lid on inflation yet, despite the Fed's efforts."
The S&P 500 is on track to close out its ninth losing week in the last 10.
Stocks also tumbled in Europe for a second day after the European Central Bank said it would soon raise interest rates for the first time in more than a decade to combat inflation.
Germany's DAX lost 2.4%, France's CAC fell 2.4% and the FTSE 100 in London dropped 2.1%.
In Asian trading, stocks in Shanghai rose 1.4% following news that inflation remained subdued at 2.1% in May.
With inflation below the government's 3% target, Chinese leaders have more leeway to offer policy supports for their economy when anti-COVID restrictions may be slowing businesses.
Tokyo's Nikkei 225 index lost 1.5%, while the Kospi in Seoul shed 1.1%.
