Debt Limit Policy Questions: How Long Do
Extraordinary Measures Last?
Updated January 25, 2024
“Extraordinary measures” are operations undertaken by the Department of Treasury to prevent a binding
debt limit. Federal debt subject to the statutory limit, codified at 31 U.S.C. §3101, cannot legally exceed
that limit. This Insight examines the factors that influence how long extraordinary measures can prevent a
debt limit from binding and summarizes recent extraordinary measures experiences.
What Are Extraordinary Measures?
Extraordinary measures are actions the Treasury Secretary uses to delay a binding debt limit. Two
provisions in statute—5 U.S.C. §8348 and 5 U.S.C. §8909—authorize extraordinary measures. These
measures have been regularly invoked in recent years. The Secretary regularly provides detailed
descriptions of extraordinary measures upon implementation. Recently, these measures have included
suspension of debt issuances to certain federal retirement accounts and for state and local government
securities. Once lawmakers raise or suspend the debt limit and extraordinary measures end, Treasury must
compensate any impacted federal accounts for their lost savings. Treasury may also adjust the operating
cash balance in its general account in response to a debt limit episode, though that is a regular financial
management tool rather than an extraordinary measure. For more background on extraordinary measures,
see CRS Insight IN10837, Debt Limit Policy Questions: What Are Extraordinary Measures?.
Variation in Extraordinary Measures Endurance
The length of time between implementation of extraordinary measures and their projected exhaustion is a
function of several factors, including legislative changes that affect the deficit, the timing of federal
receipts, and the timing of federal outlays. Extraordinary measures available to Treasury can change over
time as federal statutes (and Administration interpretations) change. The debt room that each measure
provides also shifts for reasons specific to the measure and underlying account. Descriptions of recent
extraordinary measures suggest that the extraordinary measures used and the debt room provided by those
measures have been relatively constant in recent years.
The amount of time it takes to exhaust extraordinary measures depends not only on how much debt room
those measures provide, but also how quickly the federal debt subject to the limit is rising. All else equal,
higher net federal deficits will translate to faster increases in debt subject to limit, which can be caused by

general decline in economic performance, legislative changes that increase outlays or decrease revenues,
or other factors. Intragovernmental debt, or debt one part of the government owes another part (typically
that the general fund owes trust funds), also contributes to debt subject to the limit, though it does not
contribute to debt held by the public because it is not owed to an outside creditor. Changes in
intragovernmental debt therefore also lead to changes in federal debt subject to limit, even if those
changes do not reflect shifts in what the government owes to other financial actors.
The speed at which the federal debt grows is also affected by short-term variation in federal budget
outcomes (e.g., surpluses and deficits) across months, as shown in Figure 1. Much of that variation
results from the timing of tax receipts from federal income tax returns.

Notes: Positive values represent surpluses; negative values represent deficits.
Payments and collections for many federal programs are also made on certain days of the week or month,
which can lead to daily fluctuations that are very difficult to predict as extraordinary measures near
exhaustion.
Figure 2 shows the projected endurance of extraordinary measures in every implementation period since
2011. Recent experiences illustrate that while seasonal patterns and fluctuations in general debt
acquisition are somewhat helpful in determining the endurance of extraordinary measures, the context
around each experience is highly influential in determining the ultimate effectiveness of extraordinary
measures in preventing a debt limit from binding.

Extraordinary Measures in 2023
Treasury Secretary Janet Yellen began implementing extraordinary measures on January 19, 2023, as
federal debt subject to limit approached the statutory debt limit of $31.4 trillion. A May 1, 2023, letter to
Congress stated that “our best estimate is that we will be unable to continue to satisfy all of the
government’s obligations by early June, potentially as early as June 1.” A May 1, 2023, CBO blog post
also projected extraordinary measures exhaustion in early June. Projections from CBO and Treasury
earlier in 2023, along with a Moody’s Analytics estimate in March, had forecasted that such measures
would last into late summer or early fall. Such estimates are inherently uncertain, as each of these
forecasts emphasizes. Treasury ceased implementation of extraordinary measures on June 5, 2023,
following enactment of an increase in the debt limit through the Fiscal Responsibility Act (P.L. 118-5),
and affected government accounts were restored to normal operations.
