NEW YORK, Feb 12 — Federal Reserve Chair Janet Yellen said the central bank was not to blame for the tumult that has engulfed financial markets this year and is unlikely to roll back its December interest-rate increase in response.

Yellen added that the Fed was taking another look at negative interest rates as a potential policy tool if the US economy faltered, a scenario some investors view as a mounting possibility amid a darkening outlook for world growth.
