The Overrated Debt Ceiling
Republicans can and should take a stand in the coming months.

Sometime in the next 30 to 60 days the federal government will reach the legal limit on its ability to borrow, setting up the next potential budget crisis in Washington. The debt is currently $16.4 trillion, technically in excess of the statutory limit, and the Treasury Department has been using “extraordinary measures,” such as delaying payments to federal retirement programs, in order to push back the final day of reckoning.

But Treasury’s ability to push off the deadline is almost spent, and unless Congress authorizes an increase in the debt limit, we will face yet another financial cliff. With Republicans in Congress calling for spending reductions as the price for increasing the debt limit, and President Obama insisting that he will not negotiate on the issue, we may soon be looking back on the fiscal-cliff deal as a model of relative comity.

Unfortunately, much of what we are being told about the debt limit and the upcoming fight is simply untrue. For example, President Obama warns that failing to increase the debt ceiling would “force the government to default on its obligations.” Not so.

There are two parts to the obligations subject to the debt ceiling: that part of the principal maturing during the time in question and the interest payments that the federal government must make on its debt. Between February 15 and March 15 of this year, the federal government will owe roughly $38.1 billion in interest payments. Failure to make those payments would indeed result in default. However, the federal government will also collect an estimated $277 billion in taxes and other revenue over that same period, meaning there will be more than enough money available to make those interest payments.

True, the federal government would not have enough revenue to continue spending the $452 billion that it otherwise would over that period. It would have to prioritize its expenditures until the debate was resolved. But there would be, for example, enough money to afford the interest on the debt, military salaries, Social Security, and Medicare, with at least $90 billion left over for other things.

As far as the principal goes, roughly $500 billion in debt will mature within the window between February 15 and March 15. Of course, the federal government does not actually pay off this debt (if it did, our debt would be going down rather than up) but rolls it over, substituting new debt for the maturing debt. As outgoing Treasury secretary Timothy Geithner testified in 2011, “Under normal circumstances, investors who hold Treasuries purchase new Treasury securities when the debt matures, permitting the United States to pay the principal on this maturing debt.” Since there is no net new debt as a result of the rollover, the new securities do not run afoul of the debt ceiling.

Theoretically, there could be a problem if no one is willing to buy the new securities. In that case, Treasury would not be able to issue a sufficient amount of new securities to pay for the securities that are maturing. However, unless the debate were to remain unresolved for an extremely prolonged period, there is no evidence that investors will be unwilling to buy U.S. debt in the short term.

More likely is the possibility that Treasury might have to offer higher interest rates on this rolled-over debt, a not insubstantial concern: A one-percentage-point increase in interest rates could cost taxpayers more than $100 billion per year. But to keep the situation in perspective, that amount is less than the $175 billion we will borrow from February 15 to March 15. Besides, if we are really worried about interest rates, what about the increased costs we can expect if we fail to get federal borrowing under control?
