US STOCKS-Wall Street tumbles as fresh data fuels inflation fear

By Noel Randewich and Pranav Kashyap

March 28 (Reuters) - Wall Street stocks ended sharply lower on Friday, with selloffs in Amazon, Microsoft and other technology heavyweights, after U.S. data stoked fears of weak economic growth and high inflation as the Trump administration ratchets up tariffs.

U.S. consumer spending rebounded less than expected in February while a measure of underlying prices increased the most in 13 months.

Adding to concerns, a University of Michigan survey showed consumers' 12-month inflation expectations soared to the highest in nearly 2-1/2 years in March, and that consumers expect inflation to remain elevated beyond the next year.

That data fueled fears that a rush of tariff announcements from U.S. President Donald Trump since taking office in January will boost prices of imported goods, drive inflation and deter the Federal Reserve from cutting interest rates.

Inflation and tariff worries sent shares of Wall Street's most valuable companies sharply lower, with Apple AAPL.O, Microsoft MSFT.O and Amazon AMZN.O all losing ground.

"One of the other big cautionary points for investors is that the inflation impact of tariffs has yet to show up in the data, which is why we believe this is the calm before the tariff storm, with inflation likely to head more north than south in the coming months," said Greg Bassuk, CEO at AXS Investments in New York.

According to preliminary data, the S&P 500 .SPX lost 113.03 points, or 1.99%, to end at 5,580.28 points, while the Nasdaq Composite .IXIC lost 483.30 points, or 2.71%, to 17,320.73. The Dow Jones Industrial Average .DJI fell 724.84 points, or 1.71%, to 41,576.15.

Interest rate futures suggest traders see a 76% likelihood that the Fed will cut interest rates by 25 basis points by its June meeting, according to CME FedWatch.

With Friday's losses, the S&P 500 is down about 9% from its record high close on February 19. The Nasdaq is down around 14% from its record high close on December 16.

"The problem is we don't know the rules and businesses really struggle with that," said Bob Doll, chief executive officer of Crossmark Investments.

"Part of the economic weakness we're experiencing and likely to see more of is a function of individuals and businesses saying, 'I'm not quite sure what tomorrow's going to bring, so I'll just be a little more cautious.'"

The CBOE volatility index .VIX rose 3 points to a one-week high.

A report noted that policymaker Mary Daly still views two interest-rate cuts this year as a "reasonable" expectation.

Trump's steadfast commitment to a 25% tariff on auto imports, set to take effect next week, weighed on auto stocks for a second day, with General Motors GM.N and Ford F.N both falling.

Attention now turns to a fresh round of tariffs the Trump administration is set to unveil on April 2, with Trump recently hinting that these measures might diverge from the straightforward tit-for-tat duties previously pledged.
