The Fed Chair is expected to defend the post-crisis banking rules President Trump has pledged to undo and investors will be interested to see if her economic outlook aligns with his. When it comes to interest rates, Yellen isn't expected to do much more than repeat the "gradual" pace guidance that was used in the Fed's last statement.

Meanwhile, the EU and other U.S. trading partners have begun laying the groundwork for a legal challenge to an American border tax proposal in a move that could trigger the biggest case in World Trade Organization history.

Evacuation orders for 188,000 Northern California residents remain in effect today as engineers work around the clock at America's tallest dam. "It would be a massive blow to the state's water system if they lose Oroville," said Peter Gleick, a water researcher at the Pacific Institute. The big worry doesn't center on the dam itself, but that a collapse of the spillway could cut into the hillside and lead to a "cascading failure."
