The rate of interest used in calculating the amount of post-judgment interest is the weekly average 1-year constant maturity (nominal) Treasury yield, as published by the Federal Reserve System each Monday for the preceding week (unless that day is a holiday in which case the rate is published on the next business day).
The post-judgment interest rate for judgments entered from 17 September, 2018 through 23 September, 2018 is: 2.55%
Prior to 21 December 2000, the rate of interest was based on the coupon issue yield equivalent (as determined by the Secretary of the Treasury) of the average accepted auction price for the last auction of 52 week T-bills settled immediately preceding entry of the judgment. The most recent auction of 52-week Treasury bills was held on 28 November 2000.
