Current political and economic issues succinctly explained.


The U.S. Treasury has borrowed trillions of dollars over the past decade, much of it from foreign investors, to help finance two long wars, rescue the U.S. financial system, and promote economic growth via fiscal stimulus. The country’s ability to borrow is restricted by statute, and Congress has perennially been called upon to authorize the issuance of new debt space. The federal government reached its borrowing capacity in May 2013, and, in the absence of new borrowing authority from Congress, the Treasury is taking extraordinary measures to meet its financial obligations. The United States has always been able to raise its debt limit in a timely fashion, and many economists assert that a failure to do so in late 2013 would plunge the government into default and precipitate an acute fiscal crisis.

What is the U.S. federal debt limit?

More From Our Experts

The government must be able to issue new debt as long as it continues to run a budget deficit. The debt limit, or "ceiling," sets the maximum amount of outstanding federal debt the U.S. government can incur by law. As of May 2013, this number stands at $16.699 trillion. Increasing the debt limit does not enlarge the nation’s financial commitments, but allows the government to fund obligations already legislated by Congress.

Hitting the debt ceiling would hamstring the government’s ability to finance its operations, like providing for the national defense or funding entitlements such as Medicare or Social Security. Under normal circumstances, the government is able to auction off new debt (typically in the form of U.S. Treasury securities) in order to finance annual deficits. However, the debt limit places an absolute cap on this borrowing, requiring congressional approval for any increase (or decrease) from this statutory level.

A debt limit was instituted with the Second Liberty Bond Act of 1917, and Congress has raised the cap more than seventy times since 1962. Some analysts contend that by requiring legislative consent, the debt limit affords Congress some oversight authority and engenders some fiscal accountability. Historically, opposition parties have often used debt-limit negotiations to protest existing policies.

Increasing the debt limit does not enlarge the nation’s financial commitments, but allows the government to fund obligations already legislated by Congress.

How has the debt limit been raised recently?

The debt ceiling was raised as part of the Budget Control Act of 2011, a bill signed by President Obama in August of that year, just hours before a government default. The last-minute legislative compromise set forth a process by which Treasury’s borrowing capacity was increased by a total of $2.1 trillion in three increments: by $400 billion in August, $500 billion in September, and $1.2 trillion in January 2012.

The federal government hit its debt limit again in December 2012, whereupon Treasury was forced to take emergency measures to extend borrowing for several weeks. In February, President Obama signed the No Budget, No Pay Act of 2013, a bill that suspended enforcement of the debt ceiling until late May. On May 19, the federal borrowing limit came back into force and was raised $305 billion to $16.699 trillion.

When will the United States hit its debt ceiling?

The federal government reached its capacity to issue debt [PDF] on May 20, 2013, directly after the ceiling was last raised. However, Secretary Jacob Lew, as his predecessors had before him, said Treasury would begin taking certain "extraordinary measures" (discussed below) that would enable the government to pay its bills and stave off default for several weeks. "I respectfully urge Congress to protect America’s good credit and avoid the potentially catastrophic consequences of failing to act by increasing the debt limit in a timely fashion."

On October 1, Secretary Lew penned another admonitory letter to Congress that specified October 17 as the date by which "final extraordinary measures" would be exhausted. "There are no other legal and prudent options to extend the nation’s borrowing authority," he wrote.

What can the government do if the debt limit isn’t raised?

The U.S. Treasury has the power take extraordinary measures to forestall a default—the point at which the government fails to meet principal or interest payments on the national debt. These include under-investing in certain government funds, suspending the sales of nonmarketable debt, and trimming or delaying auctions of securities. Congressional delay in raising the debt ceiling forced Treasury to begin taking some of these measures in May 2011, in January 2013, and again in May of that year.

If Congress does not act to raise the debt limit despite such emergency measures, federal spending would have to plummet or taxes would have to rise significantly (or a combination thereof). However, former Treasury secretary Timothy Geithner warned in the past that because the government’s obligations are so great, "immediate cuts in spending or tax increases cannot make the necessary cash available."

If Treasury is unable to issue new debt or take further actions to bridge the deficit, the government would be forced to default on some of its financial commitments, limiting or delaying payments to creditors, beneficiaries, vendors, and other entities. Among other things, these payments could include military salaries, Social Security and Medicare payments, and unemployment benefits.

What are the implications for financial markets?

Most economists, including those in the White House and from former administrations, agree that the impact of an outright government default would be severe. Federal Reserve Chairman Ben Bernanke has said a U.S. default could be a "recovery-ending event" that would likely spark another financial crisis. Short of default, officials warn that legislative delays in raising the debt ceiling could also inflict significant harm on the economy.

Many analysts say congressional gridlock over the debt limit will likely sow significant uncertainty in the bond markets and place upward pressure on interest rates. Rate increases would not only hike future borrowing costs of the federal government, but would also raise capital costs for struggling U.S. businesses and cash-strapped homebuyers. In addition, rising rates could divert future taxpayer money away from much-needed federal investments in such areas as infrastructure, education, and health care.

The protracted and politically acrimonious debt limit showdown in the summer of 2011 prompted Standard and Poor’s to take the unprecedented step of downgrading the U.S. credit rating from its triple-A status, and analysts fear such brinksmanship in late 2013 could bring about similar moves from other rating agencies. "Failure to raise the federal debt ceiling in a timely manner (i.e., several days prior to when the Treasury will have exhausted extraordinary measures and cash reserves) will prompt a formal review of the U.S. sovereign ratings and likely lead to a downgrade," said Fitch Ratings, which maintains a "negative" outlook on the U.S. triple-A rating.

A 2012 study by the nonpartisan Government Accountability Office estimated that delays in raising the debt ceiling in 2011 cost taxpayers approximately $1.3 billion for FY 2011.

The stock market also was thrown into frenzy in the lead-up to and aftermath of the 2011 debt limit debate, with the Dow Jones Industrial Average plunging roughly 2,000 points from the final days of July through the first days of August. Indeed, the Dow recorded one of its worst single-day drops in history on August 8, the day after the S&P downgrade, tumbling 635 points.

The United States failed to pass an annual spending measure by October 1, 2013, the start of the fiscal year, resulting in a partial shutdown of federal services that analysts say could eventually drag on economic growth, and even cause a recession if no action is taken in the short term. "If such projections prove accurate, the weaker than expected economic expansion would be even more susceptible to the adverse effects from a debt ceiling impasse than prior to the shutdown," said a brief from the Treasury Department [PDF].

What are the implications for the dollar?

Historically, the U.S. Treasury market has been driven by huge investments from surplus countries like Japan and China, which view the United States as the safest place to store their savings. A 2011 Congressional Research Service report suggests that a loss of confidence in the debt market could prompt foreign creditors to unload large portions of their holdings, thus inducing others to do so, and causing a run on the dollar in international markets. However, others claim that a sudden sell-off would run counter to foreign economic interests, as far as those interests run parallel to a robust U.S. economy.


While many U.S. exporters would benefit from dollar depreciation because it would increase foreign demand for their goods (effectively making them cheaper), the same firms would also bear higher borrowing costs from rising interest rates.

A potential long-term concern of some U.S. officials is that persistent volatility of the dollar will add force to recent calls by several other countries for an end to its status as the world’s reserve currency. A 2010 survey performed by the McKinsey Global Institute found fewer than 20 percent of business executives surveyed expected the dollar to be the dominant global reserve currency by 2025.

Does a federal debt limit still make good policy sense?

Many experts contend that the federal debt ceiling is an anathema to sound fiscal policy, suggesting it unwise to inhibit the government’s ability to meet financial obligations already legislated. "It serves no useful purpose to allow members of Congress to vote for vast cuts in taxation and increases in spending and then tell the Treasury it is not permitted to sell bonds to cover the deficits," writes budget expert Bruce Bartlett. "No other nation has such a screwy system," he notes.

A GAO analysis of the 2011 debt ceiling crisis recommended "that Congress should consider ways to better link decisions about the debt limit with decisions about spending and revenue to avoid potential disruptions to the Treasury market and to help inform the fiscal policy debate in a timely way."

In December 2012, the White House proposed amending the law in order to grant the president greater freedom to raise the debt ceiling as needed. Under the proposal, which was rejected by the GOP leadership, the president would have been empowered to effectively raise the limit unilaterally unless a two-thirds majority of Congress voted in opposition.

Chairman of the Senate Republican Policy Committee John Barrosso (R-WY) said Congress should not relinquish its control over the issuance of federal debt. "By exercising its constitutional authority through a debt limit, Congress allows itself a moment of reflection to consider the policies that have led to the current debt and consider reforms that will decrease future debt trajectory." He adds that ending the limit "would remove the last action-forcing mechanism to address our nation’s runaway debt."

How does a debt limit crisis differ from a government shutdown?

A partial federal shutdown took place on October 1, 2013, after Congress failed to appropriate funds for the current fiscal year. This last occurred in October 1995. In such a case, a specific set of procedures is enacted. A large portion of the federal government—work deemed "non-essential"—is suspended indefinitely and workers are furloughed without pay until funding is reestablished. A shutdown does not impede the government’s ability to pay interest or principal on its debt as long as Treasury has appropriate headroom under the ceiling. In other words, a shutdown does not precipitate a federal default.

On the other hand, if Congress fails to raise the debt limit, the government can no longer borrow funds, but federal operations may continue for the period that Treasury is able to use existing revenue or secure additional resources through special measures. Therefore, most employees will continue to be paid, at least in the short term. However, Treasury’s continuing inability to borrow further capital would eventually lead to a default, assuming radical revenue increases or spending decreases are not instituted.

Most experts agree that the potential negative consequences of a debt-limit debacle are much greater and far-reaching than that of a shutdown—particularly given the risk of a government default that would jeopardize the full faith and credit of the United States. The impact of a shutdown, while painful to the workers who are furloughed and the citizens who are temporarily denied certain government services, is limited to the symbolic message of political paralysis it presents to markets.
