The dollar is dipping

The index is down by 0.2% at 100.84 at 7:49 a.m. ET.

After Monday's close, Fed Chair Janet Yellen said that the Fed is focused on allowing the economy to maintain its gains.

"Before, we had our foot pressed down on the gas pedal trying to give the economy all the oomph we possibly could," she said in a speech at the University of Michigan.

Now, the Fed is "allowing the economy to kind of coast and remain on an even keel to give it some gas, but not so much that we're pressing down on the accelerator," she added. "That's a better stance of monetary policy."

Separately, JOLTS Job Openings will be released at 10 a.m. ET.
