Dennis Lockhart, president of the Federal Reserve Bank of Atlanta

Economic conditions in the United States have largely returned to normal and a Federal Reserve decision to raise interest rates should come soon, Atlanta Fed President Dennis Lockhart said on Monday.

"I think the point of 'liftoff' is close," Lockhart said in prepared remarks for an address to the Atlanta Press Club. "The economy has made great gains and is approaching an acceptable normal ... conditions are no longer extraordinary."
