Hedging Oil Price Risk with Call Options
  • NeedOil has oil price risk
  • Issue How can it reduce its exposure?
  • Solution
  • NeedOil signs a contract with OPTCO where OPTCO
    pays NeedOil
  • 250,000 x (Poil - 15) if Poil gt 15
  • 0 if Poil lt 15
  • OPTCO requires a premium equal to 100,000

Call Option Contracts
  • NeedOils contract with OPTCO is an example of a
    derivative contract, called a call option.
  • A Derivative contract is a contract whose payoff
    or value is derived from the value of some other
    asset or index.
  • The asset on which the derivative contract is
    based is called the underlying asset
  • A call option contract pays the purchaser of the
    option a positive amount if the underlying asset
    exceeds the exercise price.
  • The option price is the amount paid for the
    option.
  • For every call option buyer, there is a call
    option seller.

11
Selling a Call Option
  • Payoff to a Seller (OPTCO) of a Call Option on
    Oil with An Exercise price of 15

12
Put Options
  • Put option contract receives a positive payoff
    only if the value of the underlying asset falls
    below the exercise price

13
Cash Settlement versus Physical Delivery
  • Some options are settled in cash (like the ones
    NeedOil used)
  • Other options are settled with the physical
    delivery of the underlying asset
  • Example call option on oil 1,000 barrels with
    exercise price of 15
  • If oil price at expiration 18, then the option
    buyer would exercise the option to buy 1,000
    barrels for 15 a barrel

14
Basis Risk
  • Basis risk refers to the uncertainty in the
    relationship between the variable being hedged
    and the derivative contract payoff being used to
    hedge
  • Examples
  • firm takes delivery in New Orleans, derivative
    contract is based on New York prices
  • grade of the underlying asset used differs from
    the grade on which the contract is based.

15
Determinants of the Price of Call and Put Options
  • An Increase in Call Option Price Put Option
    Price
  • the value of the
  • underlying asset Increases Decreases
  • the exercise price Decreases Increases
  • the volatility in the
  • return of the
  • underlying asset Increases Increases
  • the time to maturity Increases Increases
  • interest rates Increases Decreases

16
Hedging with Forward Contracts
  • Alternative method of hedging Contract with F-CO
  • F-CO does not demand an upfront premium
  • Instead NeedOil pays F-CO if the price of oil
    falls below 15
  • F-CO pays 250,000 x (Poil - 15) if Poil gt 15
  • F-CO receives 250,000 x (15 - Poil) if Poil lt 15

18
Hedging with Forward Contracts
  • A forward contract or a futures contract gives
    the buyer (NeedOil) a symmetric payoff
  • equal to the difference between the actual price
    of the underlying asset and some pre-determined
    price
  • called the forward price or futures price.

Forward Prices
  • Demand and supply of contracts determines the
    forward price
  • People will always demand more contract or supply
    more contracts unless
  • Cost of carry relationship is true
  • forward price spot price at time t cost of
    carry,

21
Example of the Cost of Carry Relationship
  • Assume
  • spot price of oil is 16 a barrel,
  • the interest rate equals 9,
  • cost of storing and insuring oil for one year is
    1
  • 1-yr forward price 16 16 x (0.09 0.01)
  • 17.60

22
Example of the Cost of Carry Relationship
  • Suppose the 1-yr forward price 18.00 and the
    cost of carry equals 17.60
  • Then, you could sell (take a short position) a
    forward contract (agree to sell oil in one year)
    at the 18.00 price.
  • Simultaneously,
  • buy oil today
  • store and insure the oil for 1 year for a total
    of cost of 17.60 a barrel
  • at the end of the year, you would make 0.40
    regardless of what happens to the price of oil
    (i.e., there is no risk).
  • Therefore, 18.00 is not a price that will clear
    the market

Swap Contracts
  • Swap contracts are a series of forward contracts
  • Description of an Oil Swap
  • Let Pt price of oil at time t
  • 6 Mnths 12 Mnths 18 Mnths 24 Mnths
  • Payoff (P6 mnths - 15) (P1 yr - 15) (P18
    mnths - 15) P2 yrs - 15)
  • to NeedOil x 250,000 x 250,000 x 250,000 x
    250,000
  • Payoff to (15 - P6 mnths) (15 - P1 yr) (15
    - P18 mnths) (15 - P2 yrs) SWAPCO x 250,000 x
    250,000 x 250,000 x 250,000

27
Swap Contracts
  • 2-year Interest Rate Swap Contract between
    NeedOil and SWAPCO
  • rt one-year T-bill rate at time t
  • each entry is multiplied by 1 million
  • 6 Mnths 12 Mnths 18 Mnths 24 Mnths
  • Payoff
  • to NeedOil (r6 mnths - 5) (r1 yr - 5) (r18
    mnths - 5) (r2 yrs - 5)
  • Payoff
  • to SWAPCO (5 - r6 mnths) (5 - r1 yr) (5 -
    r18 mnths) (5 - r2 yrs)

28
Comparison Of Derivatives Insurance
  • Derivative contracts
  • Usually used to hedge risk arising from
    unexpected changes in market prices
  • Note market prices affect many firms
  • Insurance contracts
  • Usually for risk arising from losses specific to
    the insured.

29
Comparison Of Derivatives Insurance
  • Influence a particular firm has on payoffs from
  • Derivative contracts - little, if any
  • Insurance contracts
  • Considerable, through its loss control activities
  • gt greater moral hazard problems with insurance
  • gt more investigation and monitoring costs must
    be incurred with insurance contracts than with
    derivatives
  • gt contracts with retention (deductibles,
    limits, etc)

30
Comparison Of Derivatives Insurance
  • Contracts based on firm specific factors (as
    opposed to market prices or indices) have less
    basis risk.
  • Derivative markets generally are more liquid than
    insurance markets.
  • A liquid market exists when someone can sell or
    buy an asset quickly with little price
    concession.
  • Factors affecting liquidity
  • Moral hazard problems
  • Is creditworthiness involved?

31
Comparison Of Derivatives Insurance
  • When prices change, there tend to be winners and
    losers
  • gt firm values often are negatively correlated
  • gt risk can be reduced with just two parties
  • In contrast, the liability and property losses
    tend to be independent across firms.
  • gt reduce risks by diversification with many
    participants

32
Comparison Of Derivatives Insurance
  • Summary of Main Differences
  • Characteristics Derivatives Insurance
  • Type of risk hedged Market price risk Firm
    specific risk
  • Contracting costs
  • (due to moral
  • hazard, illiquidity) Low High
  • Basis risk High Low

33
Institutional Material
  • Over-the-Counter versus Exchange Traded
    Derivatives
  • An over-the-counter (OTC) transaction resembles a
    privately negotiated contract between two firms.
  • Exchange traded derivatives are standardized
    contracts with the terms established by the
    exchanges.
  • tend to be more liquid

34
Institutional Material
  • The greater liquidity also is due in part to the
    method used to ensure performance.
  • With OTC contracts, firms assess the default risk
    (or credit risk)
  • With exchange traded contracts, default risk is
    reduced by using
  • performance bonds, called margin
  • daily marking to market

35
Institutional Material
  • Example
  • required margin 20 of the positions value
  • value of position 1,000.
  • you must post margin
  • if futures price falls so the value equals 900
  • amount lost on position is subtracted from margin
  • gt you must add
  • Margin and marking to market imply that you can
    trade anonymously, which increases liquidity.

36
Main Types of Risk Hedged with Derivatives
  • Foreign exchange rates
  • break-down of the Bretton-Woods system of fixed
    exchange rates in 1973
  • Interest rates
  • high level of interest rates in the 1970s and
    1980s
  • 1979 change in FED policy
  • Commodity prices
  • Equity prices

37
Reducing Risk Through Internal Diversification
  • Synergy exists when the combination of the parts
    has greater value than the sum of the individual
    values.
  • A potential source of synergy is the benefit from
    reducing firm risk.
  • Internal diversification is also costly
