Post-Judgment Interest Rates
28 U.S.C. §1961, 18 U.S.C. §3612, and 40 U.S.C. §258(e)(1) tied interest rates on judgments to the Treasury’s 52-week T-bill interest rate. The Treasury Department discontinued the auction of 52-week T-bills, so a new rate had to be established. Judgments prior to December 21, 2000 will use the old auction rates. Interest rates are now changed weekly.
Only the rate that is applied to judgments has changed. All other computational procedures remain the same.
Current rates can be found by clicking here. The applicable rate is listed under US Government Securities - Treasury Constant Maturities - 1-year. The specific rate is found under the column headed week ending MM/DD, where MM/DD is the month and week ending date, e.g., Jan 26 or Feb 2. Use the rate for the calendar week preceding the date of the Judgment.
If there is a need for rates that were in effect for periods before receipt of this notice, they can be found by selecting the "Historical Data" tab at the top of the page, then scrolling down to US Government Securities - Treasury Constant Maturities - 1 year -weekly (Friday).
If you have any questions regarding the changes to the rate, or have problems identifying which rate is applicable, please contact Policy Staff, in the Administrative Office of the Courts Accounting and Financial Systems Division, at (202) 502-2200.
