Fed's Goolsbee said the labor market and some leading economic indicators are flashing warning signs, adding that there are concerns that unemployment will continue to rise. "Historically, if the unemployment rate starts to rise and if temporary employment is negative, this is a leading indicator," Goolsbee said, noting that rising credit card delinquencies and rising small business defaults are also a cause for concern. He said that when problems begin to arise in the job market, they tend not to happen slowly. However, he declined to say whether he would favor a rate cut at the Fed's next meeting in September, but he reiterated that there was no need to tighten monetary policy when the economy was not overheating. When asked about the possible extent of the rate cut, Goolsbee said: "Everything is on the table." (Jinshi)
