If that is the case why does the LIBOR yield curve tell us the same thing? Has the Fed been buying long term LIBOR futures? Do you see those on the Fed's balance sheet? No you do not.
The LIBOR started to invert back at the beginning in December, before the Fed even announced its rate hikes.
So therefore I think you analysis is just spewing more of the myths that so many promote. The yield curve (both) is clearly stating that growth and inflation expectations are not what everyone is proclaiming.
