Rather than focusing as usual on coming earnings reports, investors remain fixated on the federal government's partial shutdown, and more importantly on the prospect of a default on debt payments by the U.S. government if the federal debt limit of $16.7 trillion isn't raised soon. U.S. Treasury Secretary Jack Lew in a letter to House Speaker John Boehner (R., Ohio) on Sept. 28 said the "extraordinary measures" the Treasury was taking to maintain its borrowing power will "be exhausted no later than Oct. 17," unless the $16.7 trillion federal debt limit is raised.
