Yellen made the comments in a meeting last weekend, according to Bloomberg.
Looks like the Fed is leaking out something to boost sentiment.
From BBG:
Federal Reserve Chair Janet Yellen voiced confidence in the durability of the U.S. economic expansion in the face of slowing global growth and turbulent financial markets at a closed-door meeting in Washington last weekend, according to two people familiar with her comments.
The people, who asked not to be named because the meeting was private, said Yellen told the Group of 30 that the economy looked to be on track to achieve growth of around 3 percent going forward. She also saw inflation eventually rising back up to the Fed’s 2 percent target as unemployment falls further, according to the people.
The market don’t really know what to do with it but the bond market is beginning to dump. It’s a sign the Fed isn’t about to rush in and do more.
