The government's borrowing rates remained very low throughout. But the Government Accountability Office nevertheless estimates that they were higher during the standoff than they would have been otherwise. The result: An additional $19 billion in interest payments will be owed over the next decade, according to the Bipartisan Policy Center.
There's a good chance the debate this year will go down to the wire if not past it.
"The two groups are farther apart than they've ever been," said Steve Bell, senior director of economic policy at the Bipartisan Policy Center.
If Congress does not approve a debt ceiling increase, some believe the president could invoke the 14th Amendment, which states: "The validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned."
By doing so, the argument goes, Obama could direct the Treasury secretary to keep borrowing in order to pay the country's bills in full.
The White House has indicated that's not a strategy the president would employ.
It would be risky politically -- there could be moves to impeach Obama.
And the country could still be hurt financially. By invoking the 14th Amendment, the president could spark a constitutional crisis -- not an affirming message to send markets already questioning Washington's ability to get beyond its dysfunction.
And yet, it's not yet clear what else the president could do to contain the damage.
"It is hard to imagine any Treasury secretary, or any president, allowing himself -- or herself -- to be the first to default on the public debt," said Joseph Minarik, research director at the Committee for Economic Development and a former chief economist at the White House Budget Office.
