Treasury Secretary Janet Yellen acknowledged Thursday that “transitory” is not the best word to use to describe rising inflation in the United States.

“I’m ready to retire the word transitory,” Yellen said at a Reuters Next conference. “I can agree that that hasn’t been an apt description of what we’re dealing with.”

Federal Reserve Chairman Jerome Powell also acknowledged this week that the inflation rocking the U.S. economy isn’t transitory and “that factors pushing inflation upward will linger well into next year.”
