DEPARTMENT OF THE TREASURY

WASHINGTON, D.C.

Description of the Extraordinary Measures

March 5, 2019

Secretaries of the Treasury in both Republican and Democratic administrations have 

exercised their authority to take certain extraordinary measures in order to prevent the United States 

from defaulting on its obligations as Congress deliberated on increasing the debt limit. Four of 

these extraordinary measures are available at this time. The other measures that have been taken in 

the past are either unavailable or of limited use.

The extraordinary measures currently available are: (1) suspending sales of State and Local 

Government Series Treasury securities; (2) redeeming existing, and suspending new, investments of 

the Civil Service Retirement and Disability Fund and the Postal Service Retiree Health Benefits

Fund; (3) suspending reinvestment of the Government Securities Investment Fund; and (4) 

suspending reinvestment of the Exchange Stabilization Fund. These measures are described in 

more detail below.

1. State and Local Government Securities

The Treasury Department has authority to suspend its issuance of State and Local 

Government Series Treasury securities (SLGS). This, however, is a limited measure that does not 

create headroom under the debt limit.

SLGS are special purpose Treasury securities issued to state and local government entities. 

In ordinary times, the Treasury Department issues SLGS to state and local governments to assist 

these governments in complying with Federal tax laws when they have cash proceeds to invest from 

their issuance of tax exempt bonds. When Treasury issues these securities, they count against the 

debt limit. There is no statutory or other requirement for the Treasury Department to issue SLGS; 

they are issued in order to assist state and local governments, and Treasury may suspend SLGS 

sales as the debt subject to limit approaches the debt limit.

This action does not free up headroom under the debt limit. Rather, it conserves headroom 

(i.e., it eliminates increases in debt that would count against the debt limit if issued). SLGS 

issuances have averaged approximately $4 billion per month, although this amount is subject to 

substantial variation from month to month. Some state and local governments issuing certain types 

of new debt after the SLGS sales are suspended will have to invest the proceeds in alternative assets 

in order to remain in compliance with tax law. 

2. Declaring a “Debt Issuance Suspension Period”

Once the debt limit has been reached, Treasury has authority to take actions regarding 

investments under the Civil Service Retirement and Disability Fund (CSRDF) and the Postal 

Service Retiree Health Benefits Fund (PSRHBF).
2

The CSRDF provides defined benefits to retired and disabled Federal employees covered by 

the Civil Service Retirement System. The fund is invested in special-issue Treasury securities, 

which count against the debt limit. 

The PSRHBF provides postal service retiree health benefit premium payments. The fund is 

invested in special-issue Treasury securities, which count against the debt limit. 

a. Declaring a “Debt Issuance Suspension Period”

Congress has given Treasury statutory authority to take certain actions in the event of a debt 

limit impasse. Specifically, the statute authorizes the Secretary of the Treasury to determine that 

Treasury will be unable to fully invest the CSRDF and the PSRHBF and that a “debt issuance 

suspension period” exists. Once the Secretary has done so, Treasury can (1) suspend new 

investments, and (2) redeem certain existing investments in both the CSRDF and the PSRHBF.

The Secretary of the Treasury does not have unlimited discretion to declare a debt issuance 

suspension period. Under the statute that governs the CSRDF and the PSRHBF, the term “debt 

issuance suspension period” means a period of time that the Treasury Secretary determines that 

Treasury securities cannot be issued without exceeding the debt limit. The determination of the 

length of the period must be based on the facts as they exist at the time.1 

Declaring a debt issuance suspension period is a limited measure that relates only to the 

CSRDF and PSRHBF; it has no impact on any other investments or any other portion of the debt. 

Moreover, it only provides limited additional time. For each month of a declared debt issuance 

suspension period, approximately $7 billion in headroom for CSRDF and $300 million in headroom 

for PSRHBF is freed up through the early redemption of existing investments held by both the 

CSRDF and PSRHBF, respectively. Thus, a three-month debt issuance suspension period, for 

example, would free up approximately $22 billion in headroom at the beginning of the debt 

issuance suspension period.2 However, because these redemptions would have otherwise occurred 

 

1 This determination does not preclude the Secretary from making a new determination at a later time with respect to the 

period of time that securities cannot be issued without exceeding the debt limit, including as the result of any 

consideration of changed circumstances.

2 The statute governing the CSRDF and PSRHBF gives Treasury authority to redeem existing Treasury securities held 

by the CSRDF and PSRHBF in an amount up to the amount of civil service benefit payments and postal service retiree 

health benefit premium payments authorized to be made from the CSRDF and PSRHBF respectively during the debt 

issuance suspension period. 5 U.S.C. § 8348(k). Treasury makes approximately $7 billion in civil service benefit 

payments from the CSRDF and $300 million in postal service retiree health benefit premium payments from the 

PSRHBF each month. Therefore, declaring a three-month debt issuance suspension period would allow Treasury to 

redeem approximately $21 billion of the Treasury securities held by the CSRDF and $900 million of the Treasury 

securities held by the PSRHBF, freeing up approximately $22 billion in headroom. The statute also authorizes Treasury 

to suspend new investments by the CSRDF and PSRHBF. The CSRDF receives approximately $3 billion in new 
3

over the course of the debt issuance suspension period, as of the end of the debt issuance suspension 

period there is no net increase in headroom created as a result of the early redemption.

During a debt issuance suspension period, civil service benefit payments and postal retiree 

health benefit payments would continue to be made as long as the United States has not yet 

exhausted the extraordinary measures. Once the extraordinary measures have been exhausted,

however, the U.S. Government will be limited in its ability to make payments across the 

government. After the debt limit impasse has ended, the statute provides that the CSRDF and the 

PSRHBF is to be made whole.3 Therefore employees and retirees are unaffected by these actions. 

b. One-time measure available in June. 

The same statute that authorizes Treasury to redeem existing investments during a debt 

issuance suspension period also authorizes Treasury to suspend new investments by the CSRDF. 

On June 28, approximately $70 billion in CSRDF investments mature. In addition, an interest 

payment of an estimated $13 billion is scheduled to be made to the fund on that date. Ordinarily the 

proceeds of the maturing investments would be reinvested and the interest payment would be 

invested. If, however, a debt issuance suspension period is in place at this time, Treasury may 

suspend this investment.4 Suspending these investments would free up and conserve a combined 

total of approximately $83 billion in headroom. In addition, the Postal Accountability and 

Enhancement Act of 2006 provides that investments in the PSRHBF shall be made in the same 

manner as investments for the CSRDF. Investing the PSRHBF in the same manner as the CSRDF 

would free up approximately $3 billion in headroom.5

 It should be understood that this suspension 

of investment is a one-time measure: it is only available at the end of June. 

 

employer and employee contributions each month. Therefore, each month approximately $3 billion in headroom that 

would otherwise be used is conserved.

3 After the debt limit impasse has ended, Treasury is required to put the CSRDF and PSRHBF investment portfolio into 

the position it would have been in if the impasse had not occurred, and to restore lost interest on the next regularly 

scheduled interest payment date on the Treasury securities held by the CSRDF and PSRHBF.

4 In addition, on September 30, 2019, the CSRDF will receive a statutory contribution of approximately $41 billion 

from the general fund of the Treasury. Ordinarily, these contributions would be invested. If, however, a debt issuance 

suspension period is in place on the particular dates when these contributions are made, Treasury may suspend these 

investments.

5

On June 28, approximately $2 billion in PSRHBF investments mature and an interest payment of approximately $1

billion is due. Ordinarily, the proceeds of the maturing investments would be reinvested and the interest payment would 

be invested. But with the investment suspension authority available, Treasury may suspend these investments.

3. Government Securities Investment Fund of the Federal Employees Retirement System (G 

Fund)

Once the debt limit has been reached, Treasury may also suspend the daily reinvestment of 

the Treasury securities held by the G Fund of the Federal Employees Retirement System Thrift 

Savings Plan (TSP).

The G Fund is a money market defined-contribution retirement fund for Federal employees. 

The fund is invested in special-issue Treasury securities, which count against the debt limit. The 

entire balance matures daily and is ordinarily reinvested. Congress has granted Treasury the 

statutory authority to suspend reinvestment of all or part of the balance of the G Fund when the 

Secretary determines that the fund cannot be fully invested without exceeding the debt limit.6

Using this measure immediately frees up headroom under the debt limit. As of February 28, 

2019, the G Fund balance was approximately $257 billion. The balance of the G Fund can fluctuate 

for a variety of reasons. Based on recent historical trends, Treasury expects that approximately 

$230 billion is a more accurate estimate of the value of the G Fund when projecting how long 

extraordinary measures may last.

During the period of the investment suspension, payments from the G Fund continue to be 

made as long as the United States has not yet exhausted the extraordinary measures. Once the 

extraordinary measures have been exhausted, however, the U.S. Government will be limited in its 

ability to make payments across the government. After the debt limit impasse has ended, the G 

Fund is made whole.7

 Therefore participants in the Thrift Savings Plan who contribute to the G 

Fund are unaffected by the actions described above.

4. Exchange Stabilization Fund

Treasury may also suspend the daily reinvestment of Treasury securities held by the 

Exchange Stabilization Fund (ESF). 

The ESF has a number of uses, including purchasing or selling foreign currencies. A portion 

of the ESF is held in U.S. dollars, and the dollar-balance of the ESF is invested in special-issue 

Treasury securities, which count against the debt limit. The entire dollar-balance matures daily. 

There is no requirement that the Treasury Department invest the ESF, so Treasury may suspend the 

investment of the dollar-balance of the ESF during a debt limit impasse. 

 

6 5 U.S.C. § 8438(g).

7 Treasury is required to restore lost interest on the next business day.
5

Suspending the daily reinvestment of the dollar-balance of the ESF immediately frees up 

headroom under the debt limit. Because the dollar-balance of the ESF is approximately $22 billion, 

this would create up to approximately $22 billion in headroom.

After a debt limit impasse, the interest lost by the ESF is not restored: there is no existing 

authority to reimburse the ESF for lost interest during the period that the dollar-balance is not 

invested.
