Charles Evans, president of Federal Reserve Bank of Chicago.

The U.S. Federal Reserve should raise interest rates slowly even as fiscal policies under President Donald Trump are likely to help push economic growth beyond sustainable levels, Chicago Federal Reserve Bank President Charles Evans said on Friday.

"Appropriate policy calls for a slow pace of normalization in order to give the real economy an adequate growth buffer to withstand downside shocks," Evans said in remarks prepared for delivery at Prairie State College in Olympia Fields, south of Chicago. "I favor taking a gradual path for the adjustment of the funds rate back toward its long-run level."
