Federal Reserve Chair Kevin Warsh said on Friday that inflation is still too high, and he suggested the Fed may have ot raise interest rates in the coming months to help bring inflation down. 

The statement, which was his first high-profile speech at the Fed's annual conference at Jackson Hole, revealed a lot clearer picture of Warsh's economic outlook than previous remarks, the Associated Press reported. 

Warsh acknowledged that inflation had cooled a bit, but he wasn't certain the underlying trends "have meaningfully improved." 

“We must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed. Otherwise, we have work to do," Warsh said.
