In 2011, ongoing political debate in the United States Congress about the appropriate level of government spending and its effect on the national debt and deficit reached a crisis centered on raising the debt ceiling, leading to the passage of the Budget Control Act of 2011.

The Republican Party, which gained control of the House of Representatives in January 2011, demanded that President Obama negotiate over deficit reduction in exchange for an increase in the debt ceiling, the statutory maximum of money the Treasury is allowed to borrow. The debt ceiling had routinely been raised in the past without partisan debate or additional terms or conditions. This reflects the fact that the debt ceiling does not prescribe the amount of spending, but only ensures that the government can pay for the spending to which it has already committed itself. Some use the analogy of an individual "paying their bills."

If the United States breached its debt ceiling and were unable to resort to other "extraordinary measures", the Treasury would have to either default on payments to bondholders or immediately curtail payment of funds owed to various companies and individuals that had been mandated but not fully funded by Congress. Both situations would likely have led to a significant international financial crisis.

On July 31, two days prior to when the Treasury estimated the borrowing authority of the United States would be exhausted, Republicans agreed to raise the debt ceiling in exchange for a complex deal of significant future spending cuts. The crisis did not permanently resolve the potential of future use of the debt ceiling in budgetary disputes, as shown by the subsequent crisis in 2013.

The crisis sparked the most volatile week for financial markets since the 2008 financial crisis, with the stock market trending significantly downward. Prices of government bonds ("Treasuries") rose as investors, anxious over the dismal prospects of the US economic future and the ongoing European sovereign-debt crisis, fled into the still-perceived relative safety of US government bonds. Later that week, the credit-rating agency Standard & Poor's downgraded the credit rating of the United States government for the first time in the country's history, though the other two major credit-rating agencies, Moody's and Fitch, retained America's credit rating at AAA. The Government Accountability Office (GAO) estimated that the delay in raising the debt ceiling increased government borrowing costs by $1.3 billion in 2011 and also pointed to unestimated higher costs in later years.Government Accountability Office.

The Bipartisan Policy Center extended the GAO's estimates and found that delays in raising the debt ceiling would raise borrowing costs by $18.9 billion.Bipartisan Policy Center.

Context Under US law, an administration can spend only if it has sufficient funds to pay for it. These funds can come either from tax receipts or from borrowing by the United States Department of the Treasury. Congress has set a debt ceiling, beyond which the Treasury cannot borrow (this is similar to a credit limit on a credit card). The debt limit does not restrict Congress's ability to enact spending and revenue legislation that affects the level of debt or otherwise constrains fiscal policy; it restricts Treasury's authority to borrow to finance the decisions already enacted by Congress and the President. Congress also usually votes on increasing the debt limit after fiscal policy decisions affecting federal borrowing have begun to take effect. In the absence of sufficient revenue, a failure to raise the debt ceiling would result in the administration being unable to fund all the spending which it is required to do by prior acts of Congress. At that point, the government must cancel or delay some spending, a situation sometimes referred to as a partial government shut down.

In addition, the Obama administration stated that, without this increase, the US would enter sovereign default (failure to pay the interest and/or principal of US treasury securities on time) thereby creating an international crisis in the financial markets. Alternatively, default could be averted if the government were to promptly reduce its other spending by about half.It's Not "Default" By Annie Lowrey at SlateDebt Ceiling: No Chance of US default By Warren Mosler at creditwritedowns.com

An increase in the debt ceiling requires the approval of both houses of Congress. Republicans and some Democrats insisted that an increase in the debt ceiling be coupled with a plan to reduce the growth in debt. There were differences as to how to reduce the expected increase in the debt. Initially, nearly all Republican legislators (who held a majority in the House of Representatives) opposed any increase in taxes and proposed large spending cuts. A large majority of Democratic legislators (who held a majority in the Senate) favored tax increases along with smaller spending cuts. Supporters of the Tea Party movement pushed their fellow Republicans to reject any agreement that failed to incorporate large and immediate spending cuts or a constitutional amendment requiring a balanced budget.

Background

Debt ceiling

In the United States, the federal government can pay for expenditures only if Congress has approved the expenditure in an appropriation bill. If the proposed expenditure exceeds the revenues that have been collected, there is a deficit or shortfall, which can only be financed by the government, through the Department of the Treasury, borrowing the shortfall amount by the issue of debt instruments. Under federal law, the amount that the government can borrow is limited by the debt ceiling, which can only be increased with a separate vote by Congress.

Prior to 1917, Congress directly authorized the amount of each borrowing. In 1917, in order to provide more flexibility to finance the US involvement in World War I, Congress instituted the concept of a "debt ceiling". Since then, the Treasury may borrow any amount needed as long as it keeps the total at or below the authorized ceiling. Some small special classes of debt are not included in this total. To change the debt ceiling, Congress must enact specific legislation, and the President must sign it into law.

The process of setting the debt ceiling is separate and distinct from the regular process of financing government operations, and raising the debt ceiling does not have any direct impact on the budget deficit. The US government passes a federal budget every year. This budget details projected tax collections and outlays and, therefore, the amount of borrowing the government would have to do in that fiscal year. A vote to increase the debt ceiling is, therefore, usually seen as a formality, needed to continue spending that has already been approved previously by the Congress and the President. The Government Accountability Office explains: "The debt limit does not control or limit the ability of the federal government to run deficits or incur obligations. Rather, it is a limit on the ability to pay obligations already incurred." The apparent redundancy of the debt ceiling has led to suggestions that it should be abolished altogether. From 1979 to 1995, the House of Representatives followed the "Gephardt Rule" which deemed the debt ceiling raised if necessary to cover appropriations.

The US has had public debt since its inception. Debts incurred during the American Revolutionary War and under the Articles of Confederation led to the first yearly report on the amount of the debt ($75,463,476.52 on January 1, 1791). Every president since Harry Truman has added to the national debt. The debt ceiling has been raised 74 times since March 1962, including 18 times under Ronald Reagan, eight times under Bill Clinton, seven times under George W. Bush and three times () under Barack Obama.

, approximately 40 percent of US government spending relied on borrowed money. That is, without borrowing, the federal government would have had to cut spending immediately by 40 percent, affecting many daily operations of the government, besides the impact on the domestic and international economies. It is unclear if the Treasury has the technological capability to disburse funds to some individuals it owes money. The Government Accountability Office reported in February 2011 that managing debt when delays in raising the debt limit occur diverts Treasury's resources from other cash and debt management responsibilities and that Treasury's borrowing costs modestly increased during debt limit debates in 2002, 2003, 2010 and 2011. If the interest payments on the national debt are not made, the US would be in default, potentially causing catastrophic economic consequences for the US and the wider world as well. (Effects outside the US would be likely because the United States is a major trading partner with many countries. Other major world powers that hold US government debt could demand immediate repayment.)

According to the Treasury, "failing to increase the debt limit would . . . cause the government to default on its legal obligations – an unprecedented event in American history". These legal obligations include paying Social Security and Medicare benefits, military salaries, interest on the debt, and many other items. Making the promised payments of the principal and interest of US treasury securities on time ensures that the nation does not default on its sovereign debt.

Critics have argued that the debt ceiling crisis is "self-inflicted," as treasury bond interest rates were at historical lows, and the US had no market restrictions on its ability to obtain additional credit. The debt ceiling has been raised 68 times since 1960. Sometimes the increase was treated as routine; many times it was used to score political points for the minority party by criticizing the out-of-control spending of the majority. The only other country with a debt limit is Denmark, which has set its debt ceiling so high that it is unlikely to be reached. If raising the limit ceases to be routine, this may create uncertainty for global markets each time a debt ceiling increase is debated. The 2011 debt-ceiling crisis has shown how a party in control of only one chamber of Congress (in this case, Republicans in control of the House of Representatives but not the Senate or the Presidency) can have significant influence if it chooses to block the routine raising of the debt limit.CBPP-The Most Terrifying Result of the Debt Ceiling Crisis-August 2, 2011
