Credit Derivatives
From 1996 to 2000 the market has grown from
$40B
to
$810B
Contracts that pass credit risk from one counterparty to
another. Allow separation of credit from other exposures.

Credit Default Swap
A buyer (A) pays a premium (single or periodic
payments) to a seller (B) but if a credit event
occurs the seller (B) will compensate the buyer.
premium
B - seller
A - buyer
Contingent payment
Reference asset

Example
• The protection buyer (A) enters a 1-year credit
default swap on a notional of $100M worth of 10-year
bond issued by XYZ. Annual payment is 50 bp.
• At the beginning of the year A pays $500,000 to the
seller.
• Assume there is a default of XYZ bond by the end
of the year. Now the bond is traded at 40 cents on
dollar.
• The protection seller will compensate A by $60M.

Types of Settlement
Lump-sum – fixed payment if a trigger event occurs
Cash settlement – payment = strike – market value
Physical delivery – you get the full price in exchange
of the defaulted obligation.
Basket of bonds, partial compensation, etc.

Total Return Swap (TRS)
Protection buyer (A) makes a series of payments
linked to the total return on a reference asset. In
exchange the protection seller makes a series of
payments tied to a reference rate (Libor or
Treasury plus a spread).

Example TRS
• Bank A made a $100M loan to company XYZ at a fixed rate
of 10%. The bank can hedge the exposure to XYZ by entering
TRS with counterparty B. The bank promises to pay the
interest on the loan plus the change in market value of the loan
in exchange for LIBOR + 50 bp.
• Assume that LIBOR=9% and by the end of the year the value
of the bond drops from $100 to $95M.
• The bank has to pay $10M-$5M=5M and will receive in
exchange $9+$0.5M=9.5M

Credit Spread Forward
Payment = (S-F)*Duration*Notional
S – actual spread
F – agreed upon spread
Cash settlement
May require credit line of collateral
Ch. 22, Handbook

slide 13
Credit Spread Option
Put type
Payment = Max(S-K, 0)*Duration*Notional
Call type
Payment = Max(K-S, 0)*Duration*Notional
Ch. 22, Handbook

slide 14
Example
A credit spread option has a notional of $100M with a maturity of
one year. The underlying security is a 8% 10-year bond issued by
corporation XYZ. The current spread is 150bp against 10-year
Treasuries. The option is European type with a strike of 160bp.
Assume that at expiration Treasury yield has moved from 6.5% to
6% and the credit spread widened to 180bp.
The price of an 8% coupon 9-year semi-annual bond discounted at
6+1.8=7.8% is $101.276.
The price of the same bond discounted at 6+1.6=7.6% is $102.574.
The payout is (102.574-101.276)/100*$100M = $1,297,237

Credit Linked Notes (CLN)
Combine a regular coupon-paying note with some
credit risk feature.
The goal is to increase the yield to the investor in
exchange for taking some credit risk.
Ch. 22, Handbook
Zvi Wiener
slide 16
CLN
A buys a CLN, B invests the money in a high-
rated investment and makes a short position in a
credit default swap.
The investment yields LIBOR+Ybp, the short
position allows to increase the yield by Xbp, thus
the investor gets LIBOR+Y+X.

FRM 2000-39 Credit Risk (22-5)
A portfolio consists of one (long) $100M asset and a default
protection contract on this asset. The probability of default over the
next year is 10% for the asset, 20% for the counterparty that wrote
the default protection. The joint probability of default is 3%.
Estimate the expected loss on this portfolio due to credit defaults
over the next year assuming 40% recovery rate on the asset and 0%
recovery rate for the counterparty.
A. $3.0M
B. $2.2M
C. $1.8M
D. None of the above

FRM 2000-62 Credit Risk (22-11)
Bank made a $200M loan at 12%. The bank wants to hedge the
exposure by entering a TRS with a counterparty. The bank promises
to pay the interest on the loan plus the change in market value in
exchange for LIBOR+40bp. If after one year the market value of
the loan decreased by 3% and LIBOR is 11% what is the net
obligation of the bank?
A. Net receipt of $4.8M
B. Net payment of $4.8M
C. Net receipt of $5.2M
D. Net payment of $5.2M
