The Federal Reserve Chair Janet Yellen said nothing new in Jackson Hole today. She said that the U.S. labour market is not yet fully recovered. But she added that the U.S. labour market was improving.

Janet Yellen said "there is no simple recipe for appropriate policy".

The Fed Chair offered no signal when the Fed will start to raise its interest rate.

Investors speculate that the Fed may hike its interest rate sooner than expected.
