The U.S. Department of the Treasury in conjunction with the Federal Reserve System provides yields for bills, notes, and bonds at various maturities for each day in which the instruments are available for trading. This app shows those yields starting on the first trading day of January 2010 onward. The Treasury provides daily updates on-line lagged by 24 hours and the app retrieves the update when it is connected to the Internet.

Additionally, you may plot the yield curve and get an estimate of the yield for all months from 1 to 360 (1 month to 30 years) by means of a slider.

The estimated yields are computed by linear interpolation between the actual yields. Moving the slider shows the estimate for any month you choose.

Almost good

This app was recently updated and works perfectly for a fast read on treasury yield curves except that it is one day late. Would be five stars if the current date was shown.

What a waste of money!

Just gives you the yield of the first day of each month. Completely useless. Should have the actual yield of each day.
