The newest daily snapshot of the U.S. Treasury par yield curve (every maturity since 1990) and real (TIPS) curve (since 2003): each tenor's level, 1-week / 1-month / 1-year change and percentiles since 1990 and 2008; the curve today, a month and a year ago; 10Y−3M, 10Y−2Y and 30Y−10Y spreads with weekly history; every 10Y−3M inversion since 1990; rises of 100 bp or more in a year; the 10-year split into real yield and breakeven inflation; the covered universe's earnings yield against the 10-year; and the risk-free rate and equity risk premium the site's valuations use. Refreshed nightly after the Treasury close.
