Growth in Credit Derivatives Market
  • Credit Derivatives
  • Newest of the derivative markets

Definitions
Credit Derivative a credit derivative allows
the holder to isolate and separate credit risk
from market risk, thus allowing this credit r
isk to be either hedged, traded,
or transferred. A premium may be due.
Credit Default Swap enables isolation and
transfer of credit risk without
transferring ownership of the asset
Digital Derivative cash settled transaction
(does not need delivery of underlying asset u
pon settlement) Total Return Swap transfer cred
it risk by swapping an underlying assets
specified total return (capital growth and
interest) between two counterparties, in retu
rn for regular payments of LIBOR spread LI
BOR the London inter-bank offer rate. The
inter-bank rate used when one bank borrows fr
om another. It is also the benchmark used to
price many capital market and
derivative transactions. Credit Spread diffe
rence in yields between an agreed reference
rate and a specific asset in question.

Credit Derivative Trigger Events
  • Payment default or bankruptcy/insolvency in the
    case of corporate credits
  • Moratorium on payments or the rescheduling of
    payments, as well as payment default
  • itself, for sovereign credits
  • Chapter 11 or bankruptcy filing by the issuer
  • failure to meet payment obligations when due
  • rating downgrade below an agreed upon level
  • change in the agreed credit spread (over a
    government bond or compared to another
  • government bond)
  • A materiality threshold (a significant price
    decline) has also to be breached and
    independently agreed.

Fee Determinants for Credit Derivatives
  • credit rating or probable swap counterparty
  • maturity
  • probability of default
  • expected value of the asset (post-default)

Why Use Credit Derivatives? Protection Buyer
  • 4 Main Reasons
  • Reduce exposure to a company or bank whose credit
    rating is deteriorating
  • To free up credit lines so that higher margin
    businesses may be transacted
  • To protect against a downgrading below a
    portfolio managers internal limits
  • To reduce credit exposures which have exceeded
    limits, possibly where interest rates or currency
    movements have exceeded expectations

Credit Default Swap in Energy Market
  • Energy Company has a large exposure to Duke due
    to trading activities
  • Energy Company wishes to reduce default risk to
    Duke
  • Energy Company buys credit derivative from
    Investment Bank to reduce (insure) Duke credit
    risk exposure purchases a DITIGAL instrument
  • Investment Bank only pays out notional amount to
    Energy Company if Duke experiences a default
    event (see Triggers)


Energy Company
Energy Company pays 82 basis points to receive,
within 1 year, 10 M from the Investment Bank if
Duke Energy defaults
Receive notional amount of credit protection
If Duke defaults within one year, the Energy
company owns default insurance that will pay
10 M regardless of the amount of the Duke default
10
10
Total Return Swap
Instead of lump sum notional payment in the event
of default, the protection buyer receives a
specified economic value for the reference credit.
Total Return Payer is the Energy Company (X) ---
seller of risk, buyer of protection
Total Return Receiver is the Investment Bank (Y)
buyer of risk, seller of protection
Reference Asset could be bond of another energy
company that Energy Company (X) has credit risk
exposure
Reference Asset
  • Energy Company (X) pays any appreciation on the
    capital value of the underlying asset as well as
    any coupons receivable
  • Investment Bank (Y) pays Energy Company (X) any
    depreciation of the capital value as well as a
    LIBOR linked floating margin
  • Energy Company (X) is guaranteed a specified
    capital value for the underlying, as well as a
    LIBOR linked income for the duration of the swap
  • Investment Bank (Y) owns the credit risk, as
    well as any income and any profits generated by
    this asset
  • Energy Company (X) retains the ownership of the
    reference asset, and must continue to fund the
    asset (reference asset)
  • If there is no credit event, there will be no
    contingent payment

Total Return Swap
Total Return Payer is the Energy Company (X) ---
seller of risk, buyer of protection
Total Return Receiver is the Investment Bank (Y)
buyer of risk, seller of protection
Reference Asset could be bond of another energy
company that Energy Company (X) has credit risk
exposure
  • Why Use Total Return Swaps?
  • lock in a specified economic value for the
    duration of the swap
  • transfer the market risk of an asset off-balance
    sheet to lower regulatory charges
  • used for trading credits on a leverage
    off-balance sheet basis

Credit Spreads
Credit Spread difference in yields between an
agreed reference rate and a specific asset in
question. London gilt market US treasur
y market
  • Example
  • T0 Corporate bond trades at 55 basis points
    over gilt
  • T1 Corporate bond now trades at 45 basis
    points over gilt
  • the credit spread has narrowed (tightened)
  • credit quality of bond/bond issuer has improved
  • WIDER CREDIT SPREADS IMPLY MORE LIKELY
  • CHANCE OF DEFAULT

Credit Spread Options
  • Energy Company X is concerned about a credit
    downgrade of one of its counterparties
  • Current counterparty is trading A rating,
    Energy Company X is concerned it will be
    downgraded to a B
  • Energy Company X buys downgrade protection in
    the form of a credit spread option
  • If the credit spread on its counterparties
    widens, downgrade from A to B, Energy Company
    X receives a payout
  • Energy Company X buys a call option on the credit
    spread (widening spread) and pays a premium

First to Default Basket Options Notional Payout
Just as a portfolio manager may purchase
protection on a single name (credit), said
manager may also purchase protection on a basket
of names (credits) two or more.
In the case of the FIRST TO DEFAULT STRUCTURE,
the credits in the basket are protected against
default for a set notional amount. The risk
credit to default triggers the basket payout and
basket termination. At this point, the other
credits are left un-hedged, and most be
re-hedged.

Collateral (security) comes in different formats


Cash


Securities


Treasuries
Can be converted to cash in case of default


Surety Bonds


Letters of Credit


Parental Guarantees
Promise made on behalf of parent to secure
activity undertaken by subsidiary, to a specific
entity (contractual form). At current time,
promise only secures the pre settlement and
settlement risk of actual transactions, no VaR or
liquidated damages. Specific entity usually must
seek legal recourse to recover against this form
of collateral in the case of default.



In Energy industry, large percentage of trading
partners rated BBB or less, and the convention i

  • Problem
  • 1. Corporate does not want to have significant
    portfolio exposure
  • to BBB risk
  • Corporate does not want to have significant
    portfolio exposure
  • to parental guarantees as security
  • Energy industry, as practice, transacts on
    parental guarantees
  • Energy industry participants heavily weighted
    toward BBB
  • Need large liquid pool from which to transact to
    make

PRACTICAL EXAMPLES
Apply Credit Derivatives to Policy Objectives
  • Individual Counterparty Hedge
  • Set traditional credit limit
  • Purchase protection in form of default credit
    derivative against credit limit (limit and
    notional amount must match)
  • Mitigate all credit exposure to counterparty by
    above off-balance sheet transaction (transferred
    risk to AA rated investment bank --- always
    risk that said bank will default)
  • Monitor available credit such that it does not
    exceed credit limit
  • Charge traders or profit center for cost of
    credit derivative
  • 100 compliance with policy while still allowing
    trading liquidity

23
23
PRACTICAL EXAMPLES
Counterparties Over Credit Limit
  • Problem/Resolution
  • Traders/marketers put deal in system that
    breaches credit limits
  • Discipline action required (see policy)
  • Company now exposed to greater risk than desired
  • Purchase default derivative to cover risk until
    situation can be resolved
  • Charge person/group responsible for cost of
    protection (against their P/L)

PRACTICAL EXAMPLES
Credit in High Volatility Months
Example, summer is high volatility
for power. Keep the deals on the book,
get paid for the extra risk that the
company is taking.
25
25
PRACTICAL EXAMPLES
Credit in High Volatility Months
Total Return Swap
lock in a specified economic value for the
duration of the swap
  • Energy Company X will raise credit limits during
    high vol months
  • Energy Company X takes on more risk during this
    period and wishes to be compensated for said
    risk
  • Total return swap pays Energy Company X a rate
    equal to LIBOR spread, and any depreciation on
    asset (Dynegy)
  • Energy Company X pays investment bank any
    appreciation on asset (Dynegy)
  • Energy Company X earns a higher rate of return
    during the swap, which compensates it for the
    increased risk that it is assuming

26
26
PRACTICAL EXAMPLES
  • Problem
  • Rumors in energy industry indicate that problems
    are brewing in California market (possibility of
    credit defaults)
  • Energy company X has large position due to
    trading transactions with PGE
  • Energy company X wants a credit hedge to offset
    against any cash flow problems PGE may incur
    (credit manager is hearing rumors, and wants some
    protection, but not costly protection
  • Energy company X credit manager buys credit
    spread call (credit widening---possibility of
    default greater), struck at current spread level,
    on PGE
  • Energy company X credit manager buys call against
    current mark to market position (notional amount
    of call equals current mark to market credit risk
    position with PGE)

27
27
PRACTICAL EXAMPLES
Credit Spreads Against Credit Migration Downward
Current credit spread is 72 bps., and credit
manager sets notional amount at 10 M. Credit
spread widens to 600 bps after 6 months, and the
option pays out over 3 M. If the credit manager
had been wrong on acting on the rumor, the cost
of the option would have been minimal. As it
was, the credit manager acted, and although PGE
did not default, the spread widen to compensate
the credit manager for the extra risk her
portfolio had taken to transact with PGE
Credit spread has widened from 72 bps to 600 bps
after 6 months, and Energy Company X gets out of
option
