The Federal Reserve barreled ahead with a third straight outsize interest rate hike Wednesday in an effort to squash high inflation but economists worry the campaign is increasingly risking a recession by next year. The Fed raised its key short-term rate by three-quarters of a percentage point to a range of 3% to 3.25%, a higher-than-normal level designed to ease inflation by slowing the economy. Fed officials now predict the key rate will end 2022 at a range of 4.25% to 4.5%. Wednesday’s rate increase is expected to reverberate through the economy, driving up rates for credit cards, home equity line of credit and other loans.
