Poll: Majority say failing to raise the debt ceiling would be a real problem

Federal Reserve Chairman Ben Bernanke said last week that a failure to raise the debt ceiling could cause an increase in interest rates that would affect debt levels, piling onto the already burgeoning debt and deficit. 

Bernanke said mortgage rates could increase by two percentage points along with other borrowing costs, which could create more fiscal uncertainty and cause a rise in the already persistently high 9.2 percent unemployment rate. 

"It's counterproductive to reducing the deficit," he said. "It's going in the opposite direction of fiscal stability."
