Definition of Bull & Bear FRN
Definition of Bull & Bear FRN
Traditional FRN
C = LIBOR + 0.25%
Bull floaters
(inverse floaters or yield curve notes) C = 17.2% - LIBOR coupon rate as the market rate ( bond price ) attract investor who is “bullish” on bond price
Bear floaters
C = 2 LIBOR - 9.12%
coupon rate as the market rate ( bond price ) attract investor who is “bearish” on bond price
Definition of Bull & Bear FRN
General expression for the coupon reset formula on an FRN:C = A R + B
( C >= 0 non-negativity constraint )
C: periodic coupon rate
R: variable reference rate (ex:LIBOR)
A is characteristic parameter which determines the type of the note.Definition of Bull & Bear FRN

Pricing on Bull & Bear FRN
without Constraint --- Example 1
If the firm considers issuing a bull floater with C=X-LIBORhow to determine the break-even XB such that if X<XB , a cost saving is achieved?
Firm Issuer Investor
Counterpart COF = (XB - LIBOR) + (LIBOR - 9.75%) = 10% (F) XB= 19.75% LIBOR 9.75% X-LIBOR

If the firm considers issuing a bear floater withC=2*LIBOR-Y, how to determine the break-even YB such that if Y>YB, a cost saving is achieved?
Firm Issuer Investor
Counterpart COF = (2 LIBOR -YB) + 2(9.75% - LIBOR) = 10% (F) YB= 9.5% LIBOR 2 LIBOR - Y 9.75%

Problem
:
In example 1, the bull floater : C=19.75% - LIBOR What if LIBOR > 19.75% ? COF = Max [0, (19.75% - LIBOR)] + (LIBOR - 9.75%) > 10%
In example 2, the bear floater : C= 2 LIBOR – 9.5% What if LIBOR < 4.75% ? COF = Max [0, ( 2 LIBOR – 9.5%)] + 2 (9.75% - LIBOR) >10%
C >= 0

Conclusions
Equilibrium pricing condition of Bull &
Bear floaters:
Implicit rate on synthetic structure equals
the explicit alternative
Bull
: more sensitive to market rate
than fixed rate
higher interest risk
Bear
: price positively related to
market rates
negative duration
Notice the role bull & bear floaters play in interest rate risk management
