Font Size: Top American economist Larry Summers is sounding the alarm on rising U.S. inflation, saying that it is ticking up quicker than he originally expected. Inflation is increasingly a more concerning and larger threat as consumer prices continue to rise, former National Economic Council Director and Treasury Secretary Larry Summers told Axios on Monday. He also criticized the Federal Reserve’s policies, suggesting that its decision to keep interest rates low could harm the economy. “Data are pointing more towards higher inflation than I expected, and sooner,” Summers told Axios. “With more inflation signs sooner than I would have expected.”
