The Curve Comparison: History chart allows you to compare the history of specific points on either the U.S. Treasury or the MMA yield curve. For example, you can compare the 10-year Treasury yield to the 2-year Treasury yield for the past 12 months. Or, if you want to compare the history of the same point on two different curves, you can compare the 2-year Treasury yield to the 2-year muni yield for the same period.
NOTE: BondDesk Group has archived over 20-years of daily Treasury & muni curve data. See "Licensing BondDesk Data" (left) if you would like to obtain the data for your own use.
