Senate to grill Federal Reserve chief Jerome Powell on efforts to tame inflation

If measures of the U.S. economy keep coming in hot, as they did in January, the Federal Reserve will likely have to raise interest rates even higher than it has already signaled — and keep them there longer — Chair Jerome Powell will likely warn in testimony to Congress on Tuesday.

Powell's first appearance before Congress in nine months coincides with recent signs that the economy remains resilient and inflation still stubbornly high. In the past year, the Fed has raised its benchmark interest rate at the fastest pace in four decades, to about 4.6%, its highest level in 15 years. But consumer spending, hiring and growth have yet to cool.

Several Fed officials said last week that they would favor raising the Fed's key rate above the 5.1% level they had projected in December if growth and inflation stay elevated. When the Fed raises its key rate, it typically makes mortgages, auto loans, credit card rates and business lending more expensive. It's a trend that can slow spending and inflation but also risks sending the economy into a recession.
