If Republicans and President Barack Obama were to fail to reach an agreement to raise the nation's borrowing authority, that would be "pretty damn dumb," said billionaire investor Warren Buffett in a taped interview that aired on CNBC on Friday.
In addition to the upcoming October or early November deadline on the debt ceiling, the prospects of a government shutdown next month also loom.
But Buffett, while critical of this type of partisan bickering, told CNBC, "the market is not gonna fall apart, because [investors] expect Washington will only act irrationally for a certain length of time."
Republicans are looking at the debt limit issue and the waning government funding as leverage to push deficit-reduction plans.
The GOP-controlled House is pushing through a stop-gap federal funding bill to avoid a shutdown, but it includes measures to gut the president's health-care law.
Obama has vowed to veto any such legislation.
