Treasury Secretary Janet Yellen on Wednesday said she sees "solid growth" in the coming year but also risks to the economic outlook. Speaking to the Wall Street Journal's CEO Council meeting, Yellen said inflation is "too high" and that a potential slowdown in Europe could "spill over" to the U.S. The Treasury chief spoke hours before Federal Reserve policymakers are wrapping up a two-day meeting at which they are expected to deliver the first 50 basis-point interest rate hike since 2000. Yellen, a former Fed chairwoman, said she's certain the central bank will use its tools to achieve a soft landing where the economy can continue to grow.
