Markets may be selling off amid fears of slowing global growth and the possibility of a September rate hike but the Fed couldn't care less, according to former Dallas Fed President Richard Fisher.

"I don't think there is a single member of the FOMC that's going to react to one day's market activity," Fisher told CNBC's "Closing Bell" in an interview, noting that the economy went unscathed after stocks entered substantial corrections in 1962 and 1967.
