Yield Curve for Taxable Bonds

guys anyone know why taxable bonds have a flatter yield curve?

is it just because of the adjustment by a fixed percentage tax on yield would affect more the higher yielding maturities than the lower yielding

or is there more to it?

Tax-free yield curve:

  • 1-year, 1.0%
  • 10-year, 3.0%
  • 30-year, 5.0%

Taxable (@ 30%) yield curve:

  • 1-year, 0.7%
  • 10-year, 2.1%
  • 30-year, 3.5%

Which curve is flatter?

taxable!

Ta da!
