The bond market controls rates, but the fed sets the floor.

For example, if you believe we would had decades of a near zero federal funds rate, you might be willing to accept a 2% yield on a 30 year bond. But if you thought the long term federal funds rate was going to be 2%, you might want 4% or more on the long bond.

The fed follows the market rates - their control is an illusion.
