Price Differential Indicator

Price Differential (or yield differential) is used to compare bond yields or interest rates, which share the same price axis, by merely subtracting the one rate/yield from another.


The yield differential between 10-year Treasury notes and 13-week Treasury bills indicates the shape of the yield curve:

  • A negative differential is a bearish signal and is usually followed by economic recession about 12 months later. 
  • A high positive reading is a bullish signal for investors. 

The chart below shows the yield on 10-year US Treasury notes and the    Dow Jones Industrial Average in the background. The      differential between 10-year US Treasury notes and 13-week US Treasury bills is plotted as an indicator.
