Hatzius, speaking on a panel here at an Atlanta Federal Reserve Bank event, said his view on the timing reflected a significant amount of slack still in the labor market and weak wage growth.

"My own view is that it's not yet time. Certainly not high time yet," Hatzius said, adding that Goldman's forecast for the first hike is for September.

"My opinion in terms of when monetary policy ought to be tightened is very late this year, or early next year."
