According to rttnews, Federal Reserve Chairman Janet Yellen says the case for another interest-rate hike has strengthened.

"In light of the continued solid performance of the labor market and our outlook for economic activity and inflation, I believe the case for an increase in the federal funds rate has strengthened in recent months," Yellen said in a speech prepared for delivery to the Jackson Hole summit.

However, the Fed's decision "always depends on the degree to which incoming data continues to confirm the Fed policy committee's outlook."

There will be no second speech from J.Yellen today. From the price action in the coming days we can evaluate how much a rate hike of 0.25% is already priced in.
