Copper Falls on Continuing Deadlock Over U.S. Borrowing Limit

Copper futures fell in New York for the second time in three sessions on concern that a congressional impasse over increasing the U.S. debt ceiling poses a risk to global growth.

There are signs that a congressional budget stalemate that partially shut the federal government may carry over to talks on raising the debt ceiling. House Speaker John Boehner said the U.S. could end up in default unless President Barack Obama negotiates, and Treasury Secretary Jacob J. Lew reiterated that the country will run out of its ability to borrow on Oct. 17.
