The debt ceiling is the maximum amount of money that the U.S. federal government is legally allowed to borrow to meet its existing financial obligations.
These obligations include:
- Funding government operations,
- Paying federal salaries,
- Servicing debt held by the public and foreign governments.
- Providing citizens with benefits such as Social Security, Medicare, and veterans’ benefits.
The debt ceiling is set by Congress and has been raised 91 times since 1959 to account for growing budget deficits and the accumulation of debt.
If the ceiling is reached, the Treasury Department cannot issue any additional securities – i.e., bonds – to raise cash and can only spend incoming tax revenues.
Failing to raise the debt limit in time would force the Treasury to default on some commitments. It could provoke an economic catastrophe, as it would be the first time the country has defaulted on its debt in its history.
History of the Debt Ceiling
The debt ceiling was instituted with the Second Liberty Bond Act of 1917, which enabled borrowing to finance the United States’ entry into World War I. Prior to this, Congress had to authorize each new issuance of debt separately.
Since 1959, Congress and the President have raised the debt ceiling 91 times. Since the start of 1993, policymakers have modified the debt ceiling 28 times.
As of July 2025, the debt ceiling is $41.1 trillion after being raised by $5 trillion as part of the “Big Beautiful Bill”. This was the largest one-time statutory increase in history.
Reaching the Debt Limit
When federal debt levels reach the statutory limit, the Treasury is unable to borrow any more money to bridge the gap between spending and revenues. It must rely only on incoming taxes and extraordinary measures to fund obligations.
These extraordinary measures include;
- Suspending investments in federal employee retirement funds;
- Exchanging government funds.
Once these options are exhausted, no alternatives remain to avoid defaulting on the country’s payments.
Consequences of Default
If Congress fails to raise or suspend the debt ceiling in time, the federal government will be unable to meet all of its legal financial obligations.
The resulting consequences could include, but are not limited to:
- Missed payments on Treasury bonds, notes, and bills, which constitute a formal default in the eyes of the credit market;
- Unpaid benefits for Social Security, Medicare, Medicaid, veterans, and more;
- Halting of student loan payments, tax refunds, military paychecks, and other obligations;
- The downgrade of the U.S. credit rating and higher borrowing costs;
- Trillions of dollars in losses from the collapse of stock and bond market valuations;
- Widespread business and personal bankruptcies due to higher financing costs and other collateral damages.
- Massive job losses and a possible increase in homelessness due to a wave of foreclosures and forced tenant vacancies.
- A deep and prolonged recession that could have a global impact due to the significance of the US economy to global trade.
Even coming close to defaulting could destabilize the financial markets and undermine the public’s confidence in the perceived creditworthiness of Treasury securities.
Rating agencies may downgrade U.S. debt if brinkmanship continues.
Debt Ceiling Showdowns
In recent years, the routine debt ceiling increase has turned into a political battle.
Some major crises include:
| 1995-1996 Shutdown | The government temporarily shuts down over debt limit negotiations. |
| 2011 Default Crisis | The credit agency S&P downgrades the U.S.’s federal debt after a prolonged impasse over raising the ceiling. |
| 2013 Shutdown | Senate Republicans vow not to raise the ceiling again to protest Democrats’ spending proposals. |
| 2021 Suspension Lapse | Senate Republicans vow not to raise the ceiling again to protest Democrats’ spending proposals. |
In these episodes, the ceiling was ultimately raised or suspended before a catastrophic default occurred.
However, the associated uncertainty that prevails during these procedures and standoffs usually weighs on the financial markets.
Debt Limit Solutions
To resolve debt ceiling impasses, some proposals that both lawmakers and administrations have pushed forward include:
- Abolishing the limit: Elected officials would be in charge of approving debt limits and spending plans without Congress oversight.
- Presidential executive actions: Minting a trillion-dollar coin to pay off the country’s debt by crediting the Treasury with that amount and then recouping the funds once the debt limit is ultimately raised.
- Legal recourses: Invoking the 14th Amendment is also a possibility that has been considered by the administration to bypass the debt ceiling. This idea, however, has not gained traction within the current Biden administration.
- Congressional rules changes: Requiring supermajorities to block increases. This would make it more difficult for lawmakers to band together, as they would have to convince Congressmen from both parties to join forces.
- Automatic Increases: Removing periodic votes to raise the ceiling and define a system that automatically lifts the ceiling as needed to remove the need to sustain subjective discussions over the topic.
Despite an often heated debate over these options, the only certain way to avert potential default is for Congress and the President to agree on legislation to raise or suspend the limit in a timely manner.
Even coming close to the brink can jeopardize market stability and harm the economy. The debt ceiling only enables borrowing for spending that has already been approved by Congress and the President, making periodic increases necessary to encourage and maintain some degree of fiscal responsibility.
Any prolonged government shutdown can have a significant impact, regardless of whether it affects the debt ceiling or not. The recent US government shutdown, which lasted a record 43 days, did not affect the debt ceiling. Still, the Congressional Budget Office recently estimated that the GDP growth rate in the fourth quarter will be reduced by 1.5%, but will increase by 2.2% in the first quarter of 2026.
