A debt limit suspension defines a minimum interval before Congress is compelled to address the debt limit again. Once the suspension ends, the debt limit is reset to accommodate the increase in federal debt during the suspension period. Once a suspension ends, the U.S. Treasury, with the help of "extraordinary measures," can pay federal financial obligations for some time after a suspension ends. Since 2013, Congress has suspended the statutory debt limit eight times.

In July 2025, however, a budget reconciliation law raised the debt limit by $5 trillion to $41.1 trillion. As of September 4, 2025, debt held by the public was $30.1 trillion and intragovernmental debt was $7.3 trillion, for a total outstanding debt of $37.4 trillion. In October 2021, Congress also chose to increase the debt limit by the fixed amount of $480 billion, and in December 2021, it increased the debt limit by $2.5 trillion to just under $31.4 trillion. Debt limit suspensions, by contrast, are silent on dollar amounts.

Treasury Secretary's Authority to Invoke Extraordinary Measures

Extraordinary measures are special strategies to handle cash and debt management during debt limit episodes. Congress gave the Treasury Secretary statutory authority to declare a "debt issuance suspension period" (DISP) when making deposits in the form of special Treasury securities into the Civil Service Retirement and Disability Fund (CSRDF) would cause the federal debt to exceed its limit. Other smaller resources, such as dollar holdings of the Exchange Stabilization Fund, also can be used. Before 2025, Treasury Secretaries had declared DISPs the business day after a debt limit suspension lapsed. During a DISP, the U.S. Treasury can use financial resources from the CSRDF and postal service retirement funds to pay federal obligations. Once a DISP ends, "the Secretary of the Treasury shall immediately issue" amounts to replenish those funds. The Treasury Secretary also must report to Congress on how extraordinary measures were used.

Once a DISP is declared, the length of time Treasury can meet federal financial obligations depends on its cash balances, the extent of funds available via extraordinary measures, and the timing of federal revenues and payments—when taxes are collected and when outlays are paid. The timing of redemption and issuances of special Treasury securities to various federal trust funds also matters.

During the previous debt limit episode, Treasury Secretary Yellen declared a DISP on January 19, 2023. In May 2023, she notified Congress that according to Treasury's best estimate, it would become unable "to satisfy all of the government's obligations by early June" absent legislation to modify the debt limit. In April 2023, however, individual income tax receipts fell short of expectations, reducing Treasury's headroom under the limit. Private projections suggested that Treasury's resources could have dipped to around $25 billion in early June 2023. CBO warned of a "significant risk" that in the first half of June 2023, Treasury might not be able to meet all obligations on time.

The Fiscal Responsibility Act of 2023 (FRA, P.L. 118-5), enacted on June 3, 2023, suspended the debt limit until January 1, 2025. The FRA also imposed statutory caps on discretionary spending and rescinded unobligated funds from various federal accounts. The debt limit was reinstated on January 2, 2025, at $36.1 trillion.

Then-Treasury Secretary Janet Yellen did not immediately employ extraordinary measures after the suspension lapsed in 2025 because scheduled redemptions from a Medicare-linked trust fund generated some headroom under the new debt limit. She did invoke authorities to use extraordinary measures starting January 21, 2025. Some observers had expected that extraordinary measures would allow Treasury to pay obligations until sometime in early September 2025.

Debt Limit Suspensions

Table 1 lists laws that have suspended the debt limit. The Budget Control Act of 2011 (BCA), which set the fiscal framework for the following decade, is also listed. The BCA also set statutory caps on discretionary spending for FY2012-FY2021. Congress, however, adjusted those caps to accommodate higher defense and nondefense spending levels. A series of Bipartisan Budget Acts, each of which addressed a broad range of budgetary issues, adjusted those caps upward, thus providing a convenient legislative vehicle for debt limit suspensions. The debt limit was also suspended in continuing appropriations acts for FY2014 and FY2018.

Table 2 shows the duration of debt limit suspensions and DISPs. The use of suspensions results in a two-step change in the debt limit. First, the debt limit is reset after each suspension lapse. Second, once Treasury's capacity to meet federal obligations has neared exhaustion, Congress then has acted either to suspend the debt limit or, as in October and December 2021, to increase it.

Table 2 also shows the substantial variation over the past decade in the length of DISPs, which ranged from 5 days to 231 days.
