According to Jinshi, former U.S. Treasury Secretary Summers pointed out that the U.S. "economic growth is faster than potential" due to fiscal stimulus driven by low unemployment and budget deficits. He believes that this confirms that the so-called neutral federal funds rate is "much higher than the 2.6% level that the Fed has been using as a guide." Summers said that based on the current facts, the Fed has no reason to cut interest rates, especially since the Consumer Price Index (CPI) data released this week showed that there was a problem with the way housing costs were calculated, resulting in data deviations.
