Except this part is just not true. A zero cost collar might be long a 9% cap and short a 1% floor or something. That means your LIBOR bond is, uh, essentially a LIBOR bond unless interest rates move a ton. Floating within a range doesn’t mean a fixed rate bond. I think whoever wrote this question needs to think about the zero-cost collar some more.

He also said “zero value”, which could confuse the issue. Zero value when? If you had a 4%/6% collar, and LIBOR moves to 7%, you certainly have value in the collar. His explanation is actually more confusing than if he’d just stuck to saying “zero cost collar”.

Agree in reality, but they set this up in CFA fantasy land and specified the strike rate be the same on the floor/cap (note they said the collar has a zero value…not a zero cost collar), so that the window which ordinarily would be have a range (like 1-9% in your example) essentially forces it to behave exactly like a fixed bond. Absurd? Yes, but it does force you into that answer.
