“Extraordinary Measures” and the Debt Limit

Following a period of suspension, the statutory debt limit was reinstated on December 9, 2017, at a level that precisely accommodated the federal borrowing undertaken to that date. On December 11 and 12, 2017, Secretary Mnuchin announced that the Treasury would implement "extraordinary measures" that delay when the debt limit will bind. Additionally, the Bureau of the Fiscal Service suspended sales of certain Treasury securities to extend the Treasury's ability to meet statutory spending requirements without defaulting on its debt obligations. These measures were used until passage of the Bipartisan Budget Act of 2018 (BBA 2018; P.L. 115-123) on February 9, 2018, which suspended the statutory debt limit until March 1, 2019. This Insight briefly examines the debt limit and the use of extraordinary measures.

What Is the Debt Limit?

As part of its "power of the purse," Congress uses the statutory debt limit (codified in 31 U.S.C. §3101) as a means of restricting federal debt. Debt subject to the limit is more than 99% of total federal debt, and includes debt held by the public (which is used to finance budget deficits) and debt issued to federal government accounts (which is used to meet federal obligations). The debt limit acts as a congressional check on recent revenue and expenditure trends, though decisions affecting debt levels may have been agreed to by Congress and the Administration well in advance of debt limit deliberations. Some past debt limit legislation has linked debt limit increases with other fiscal policy proposals.

What Are Extraordinary Measures?

Extraordinary measures represent a series of actions that postpone when Congress must act on debt limit legislation. The authority for using extraordinary measures rests with the Treasury Secretary (codified in 5 U.S.C. §8348 and 5 U.S.C. §8909). Invoking extraordinary measures has delayed required action on the debt limit by periods ranging from a few weeks to several months, depending on when such measures were enacted (see the "How Long Do Extraordinary Measures Last?" section). Accounts and members of the public that are affected by extraordinary measures must be compensated for the delay in payment that resulted from such actions when the debt limit is subsequently modified.

On December 12, 2017, the Treasury announced the extraordinary measures that are currently available. The Fiscal Service suspended issuance of State and Local Government Securities on December 8. A Debt Issuance Suspension Period was invoked on December 11, suspending new investments and redeeming certain existing investments of the Civil Service Retirement and Disability Fund and the Postal Service Retiree Health Benefits Fund. On December 12, the Treasury suspended daily reinvestment of securities held in the G Fund. BBA 2018 (P.L. 115-123) suspended the debt limit until March 1, 2019, and eliminated the need for implementation of extraordinary measures. Table 1 provides a description of the extraordinary measures used when those measures were implemented in 2017 and 2018.

How Long Do Extraordinary Measures Last?

Short-term fluctuations in federal debt levels provide for substantial uncertainty in how long extraordinary measures can last. Federal balances fluctuate on a day-to-day basis in response to a number of factors, including the timing of payments for Social Security, military benefits, and other programs; interest payments on debt obligations; and the timing of certain receipts. Prior to enactment of BBA 2018, CBO and the Treasury projected that extraordinary measures would be exhausted in March 2018.

Figure 1 shows federal daily balances to date in FY2018. The reduced variation in daily balances starting in December 2017 reflects the implementation of extraordinary measures. The sharp increase in borrowing on February 9 reflects the compensation of creditors whose payments were delayed by the implementation of extraordinary measures.

Notes: Positive numbers indicate daily surpluses, while negative numbers indicate daily deficits.

Monthly budget outcomes can also fluctuate with the timing of various activities. The federal government tends to record higher net budget surpluses in April (when many individual tax returns are filed) and September (as certain payments are due at the end of the fiscal year) while recording lower balances in other months. Figure 2 presents the average federal monthly account balances from the previous five fiscal years. Data points outside the circle indicate months that have recorded average surpluses from FY2013 through FY2017; points inside the circle represent months that have recorded average deficits in those years.
