NEW YORK, Oct 7 (Reuters) - U.S. stock index futures fell on Monday as the partial U.S. government shutdown continued with no signs of a softening in the positions of politicians over the debt-ceiling limit or budget impasse.
Republican House Speaker John Boehner vowed on Sunday not to raise the U.S. debt ceiling without a "serious conversation" about what is driving the debt, while Democrats said it was irresponsible and reckless to raise the possibility of a U.S. default.
The United States faces a deadline of Oct. 17 to raise its $16.7 trillion debt limit or risk an unprecedented debt default. The two issues of emergency funding for the government to operate and increase the U.S. borrowing authority started out separately in the House but have been merged by the pressure of time.
"Fear is mounting among investors that the upcoming debt ceiling deadline will be handled as poorly as the budget impasse has," said Andre Bakhos, managing director at Janlyn Capital LLC in Bernardsville, New Jersey.
"Given the lack of bipartisan workmanship, confidence is low and it is manifesting in poor market performance."
The S&P 500 has fallen two straight weeks and is down 2 percent from its all-time closing high of 1,725.52 on concerns about the effect of dysfunction in Washington on the economy.
