What is the purpose of this app?
This is a privately owned technical project that allows convenient, visual analysis of historical US interest rates and related economic indicators. Yield curve inversions have in the past been a reliable indicator of impending economic recessions, and this app allows you retroactively explore the yield curve shape on various dates. This website is not affiliated or sponsored by any government institution.
Where is the data compiled from?
The data on this website is a compilation of figures from various publicly available sources. Treasury yield curve data from 1990 to present is collected from the Treasury Department website and represent market rates as calculated by the US Treasury Department at the end of day. Older and supplemental datasets are obtained from the St. Louis Federal Reserve Economic Data (FRED) repository.
Why are the interest rates shown here different from the CNBC, Marketwatch, or other financial news websites?
The data on this website is provided by official Federal government sources. The interest rate quotes provided on most financial news websites is provided by a private company named Tradeweb, which reports interest rates based on their proprietary method of aggregating data from secondary market participants.
The US Treasury Department provided yield curve is known as “Constant Maturity Treasuries (CMT)”. These government reported rates are the result of a mathematical calculation that aggregates auction and secondary market prices to determine the yield curve. This article on the US Deparment of the Treasury website provides information about the “monotone convex (MC)” method used for determining the officially published CMT rates.
New information typically becomes available in the evening every weekday, except for market holidays.
