In December 2000, Congress enacted the Omnibus Appropriation Act (PL 106-554) that contained, among its various provisions, amendments to the federal statues dealing with the interest rate on federal judgments. This change affects 28 U.S.C. §1961, 18 U.S.C. §3612, and 40 U.S.C. §258(e)(1).
The revised sections took effect on all judgments entered on and after December 21, 2000. Only the rate that is applied to judgments has changed. All other computation procedures remain the same.
The interest rate for federal judgments is based on the average prices for U.S. Government Securities-Treasury Constant Maturities - 1 - year. See 28 U.S.C. § 1961, 18 U.S.C. § 3612, and 40 U.S.C. § 258(e)(1)
The interest rates for federal judgments are published by the Board of Governors of the Federal Reserve System. The rates are available below in (PDF) or text format.
The specific rate referred to in the statutes is found in the table under the two columns headed WEEK ENDING. The two dates under those columns refer to the Friday averages of the last two weeks. Under those columns you need to go down to the row which states U.S. government securities - Treasury constant maturities nominal 10 - 1-year. Where the row and columns meet - that is the rate you use.
Select the week preceding the date of judgment (or the date interest would otherwise apply under the above) and selecting the release date preceding the date of judgment. NOTE: if your judgment date is the same as the release date, you should select the prior week’s release. REASON: the releases are considered to be issued at the close of business on the date of release.
