April 8 (Reuters) - Federal Reserve Bank of Chicago President Austan Goolsbee said on Monday the U.S. central bank must weigh how much longer it can maintain its current interest rate stance without it damaging the economy.

"You've got to pay attention to how long do you want to be that restrictive," Goolsbee said of monetary policy, noting in an interview with Chicago radio station WBEZ that "if you're there too long, the unemployment rate is going to start going up."
