March 10 (Reuters) - The tech-heavy Nasdaq fell nearly 2% on Thursday as U.S. inflation rose to a four-decade high in February, cementing the chances of the Federal Reserve raising interest rate later this month.
Monthly consumer prices rose 7.9% in February from a year earlier, the Labor Department data showed, matching economists' expectations.
Investors fear it would accelerate further in the coming months as Russia's war against Ukraine drives up the costs of oil and other commodities.
"Between wages and energy prices this inflation has been pushing much higher. It just confirmed for everyone that inflation is stubbornly high," said Mike Skillman, chief executive officer of Faith Investor Services.
Fed Chair Jerome Powell had said he would back a quarter point rate increase when the central bank meets next week and would be "prepared to move more aggressively" later, if inflation does not abate as fast as expected.
Ten of the 11 major S&P sectors declined. Technology stocks .SPLRCT , which had led a rally in the previous session, led the losses with a 2.9% decline.
Chipmakers .SOX slid 3.4%, while megacap names Apple Inc AAPL.O and Tesla Inc TSLA.O slumped 3.4% and 4.2%, respectively.
A rise in U.S. 10-year Treasury yield US10YT=RR to near 2% also hit rate-sensitive tech stocks as their value rests heavily on future earnings, which are discounted more deeply when rates go up.
The S&P 500 growth index .IGX has lost 16.7% so far this year compared to a 5.7% decline in its value counterpart .IVX , which was supported by a surge in energy shares.
Energy shares .SPNY climbed 2.4% after taking a breather on Wednesday.
Meanwhile, traders now expect a 95% chance of a 25-basis point hike by the Fed in its March meeting.
Big banks fell, with Citigroup C.N dropping 2.8%. Goldman Sachs Group Inc GS.N said it was closing operations in Russia, becoming the first major Wall Street bank to exit the country following Moscow's invasion of Ukraine.
Ukraine said Moscow had ignored its plea for humanitarian access, as the opposing sides yielded nothing at the highest level talks since the Russian invasion began.
"The stock market is going to remain very volatile based on the day-to-day news coming out of Ukraine, potentially any further sanctions that the U.S. and the NATO allies impose upon Russia and the reaction from Putin," said Jimmy Lee, chief executive officer of the Wealth Consulting Group.
