What is the federal debt limit?

Established by Congress in 1917, the debt limit places a ceiling on the total amount of money the federal government can legally borrow. When policymakers authorize new spending that exceeds government revenues, the Treasury Department borrows money to finance this deficit by issuing securities, known as debt held by the public. The Treasury Department also owes money to other parts of the federal government, known as intragovernmental debt, which is subject to the same total ceiling. Requiring both House and Senate approval to adjust, the debt limit has been raised and suspended dozens of times over the past century under administrations and congresses controlled by both parties. Extending the debt limit does not authorize new spending, but rather enables the federal government to pay its bills on time and cover spending that Congress has already approved.

Where does it stand in 2021?

In August 2019, the federal debt limit stood at $22 trillion when Congress enacted a bipartisan budget deal that suspended it for two years, allowing the government to borrow without a ceiling. On August 1, 2021, the debt limit was reinstated at approximately $28.4 trillion, a level covering all borrowing during the suspension.

What happens when we reach it?

The debt limit was immediately reached upon its August 1 reinstatement. The Treasury Department must now, once again, rely on its emergency authority, known as “extraordinary measures,” to make room for more public borrowing to continue paying the nation’s bills. These measures are, effectively, accounting maneuvers that involve artificially reducing certain intragovernmental debt, such as delaying contributions to the trust funds that hold federal employees’ retirement assets. Extraordinary measures are distinctly limited, however, and only serve as a stop-gap procedure. If the debt limit is not raised or suspended before these resources are exhausted, the Treasury Department will have to rely solely on daily revenues and residual cash on hand to keep meeting the nation’s obligations. With the federal government running a large budget deficit—especially after a year and a half of COVID-19 relief spending—these funds will deplete rapidly. At that point—a day we call the “X Date”—the government will be unable to meet all of its obligations in full and on time. The Bipartisan Policy Center currently projects that absent congressional action, the X Date will arrive sometime this fall.

Note: Projections are subject to substantial uncertainty and volatility resulting from economic performance, cash flow fluctuations, and other factors. Extraordinary measures are reflected at the time that they are expected to become available. Dates shown are 1st of month. All three lines reflect cash on hand plus available extraordinary measures, or in other words, remaining room under the debt limit.

Why does it matter?

Upon reaching the X Date, the nation’s bills must be paid solely out of incoming cash flows, which are insufficient to cover all government spending. The federal government will therefore be forced to miss, delay, or reduce payments owed to individuals, businesses, or other entities. Such disruption will negatively affect the economy and the lives of individuals across the country, such as veterans, Social Security beneficiaries, and the millions of Americans who depend on government services each day. While Congress has never let this happen, the risk is incalculable. Global financial markets, which rely on the stability of U.S. Treasury securities, could plummet and the U.S. dollar’s reserve currency status could be jeopardized.

What makes this X Date particularly hard to predict?

Predicting the X Date always carries with it a high degree of uncertainty—not even the Treasury secretary can know when it will arrive—but the unique fiscal environment of the COVID-19 pandemic adds unprecedented difficulty to this year’s forecast. In addition to the Treasury Department’s cyclical yet unpredictable cash flows in a typical year, this year’s X Date will be highly dependent on when the remaining federal COVID-19 response spending disburses and whether the economic recovery continues to produce strong tax revenues. For example, the X Date could be delayed if economic growth outpaces expectations with higher-than-anticipated September tax revenues (optimistic scenario), but it could arrive on the earlier side if federal outlays increase more than expected, or the recovery slows and government revenues fall short (pessimistic scenario).

Are there costs to debt limit brinkmanship?

Recent episodes demonstrate that a mere delay in congressional action to address the debt limit presents its own financial and reputational risks to the country. In 2011, Standard & Poor’s downgraded the U.S. credit rating, citing the political brinkmanship. Another downgrade could bring even greater market disruption. Additionally, the threat of U.S. government default leading up to the X Date adds uncertainty to the financial markets and imposes real costs. In fact, the Government Accountability Office finds that investors have demanded higher interest rates for U.S. Treasury securities maturing around the time of the X Date. Specifically, GAO estimated that the 2013 delay in raising the debt limit increased the Treasury Department’s borrowing costs by tens of millions of dollars in just one year, which taxpayers bore through higher interest rates on U.S. Treasury securities.

What could happen next to avoid the X Date?

Failing to raise or suspend the debt limit before the X Date could be catastrophic for both U.S. recovery efforts and the global economy. Over the coming months, Congress could address the debt limit through one of two legislative avenues:

  1. Regular order. The House and Senate could pass legislation, overcoming any filibuster in the upper chamber with a 60-vote majority, that is signed by the president.
  2. Reconciliation process. With both Congress and the White House under control of Democrats, they could use the budget reconciliation process to raise—but likely not suspend—the debt limit. Congress must first initiate a budget resolution that outlines instructions for use of this special procedure, which would then only require a simple majority of 51 votes in the U.S. Senate and could not be filibustered.
