Fed's Powell quiet on possible 2nd term as chairman

"I have another massive challenge that I'm very focused on, and that is just to do my job every day as best I can to serve all of the American people," said Powell, whose four-year term as chair is up early next year.

He was responding to a question asked during a International Monetary Fund/World Bank panel, on whether he's focused on a second term as head of the world's most powerful central bank.
