Commodity Portfolio Management Flashcards
Commodity Characteristics
- Raw material or a primary agricultural resource, that can be purchased or sold for production and/or consumption.
- These tangible assets have no credit risks and many of them are most of time liquid.
- Commodities are traded on open markets throughout the world.
- Nearly no commodity price can go to zero, because commodities are always likely to be worth something to somebody. Only Power Prices have traded below 0.

The Actors on Commodity Exchanges

1.3.1 Types of Futures Market Participants

1.3.2 Commodity Trading Firms


1.4 Commitment of Traders Report
What does speculative participation look like as a fraction of open interest?
- The Commodity Futures Trading Commission (CFTC) publishes a weekly commodity futures/option report which breaks down the total open interest as of each Tuesday’s settlement.
-
The reports are released every Friday and provide market participants insight on how open interest is distributed among different groups of traders
- – (Producer/Merchant/Processor/User, Swap Dealers, Managed Money, and Other Reportable).
Open Interest
- number of long and short positions in a specific contract which have not been liquidated or offset by an opposing purchase or sale by the same participant.
- Non-commercials are momentum, or positive feedback traders
- commercials are on average contrarians (net short).


1.5 Open Interest
Open Interest
- number of long and short positions in a specific contract which have not been liquidated or offset by an opposing purchase or sale by the same participant.
- Increasing open interest figures are considered supportive of the underlying price trend.
– they may indicate market strength during periods of rising prices,
– or the support of a downward trend during periods of market weakness.

2.2 Commodities as a possible Inflation Hedge

3.1 Commodity Forwards–Synthetics

Basis Risk

3.1 Commodity Forwards–Several types of basic risk

3.1 Commodity Forwards–Financial Transaction Example: Power Station


3.2 Commodity Futures
• Future contract
– forward contract traded on an exchange
– standardized in terms of traded maturities, quantity of the commodity underlying the Future contract, and
– giving rise to physical delivery by the seller at maturity if not cash-settled contract.
- If the settlement is specified as financial, there must be a liquid reliable index to represent the underlying at date T (=maturity)
- Unlike an option, a Futures contains a_n obligation t_o buy (or sell).
- For both the buyer and the seller, the counterparty is the Clearing House of the Exchange.
• Long Futures Hedge -> you will purchase an asset in the future and want to lock in the price
- Short Futures Hedge -> you will sell an asset in the future and want to lock in the price
- Basis Risk:
– Difference between Spot and Futures
– Arises because of the uncertainty about the basis when the hedge is closed out
Typical pay-off structures of a futures contract

3.2 Commodity Futures–Initial Margin:

Margin: Example

3.2 Commodity Futures
• The Exchange must also provide information on

Futures prices of commodities that are investment assets such as gold and silver.

Example

3.2 Commodity Futures–Consumption Commodities
- Commodities that are consumption assets rather than investment assets usually provide no income, but can be subject to significant storage costs.
- We now review the arbitrage strategies used to determine futures prices from spot prices
- For some commodities the spot price depends on the delivery location.
- We assume that the delivery location for spot and futures are the same.

3.3 Commodity Options
Commodity Option: pay a small fee today (a premium) for the right (but not the obligation) to buy/sell a commodity at a predetermined price at a predetermined point in the future.
• Typically the underlying of an options contract listed on an exchange will be the futures
contract for the same commodity.
• Option contracts are also termed as call and put options based on the position of the
market participant when undertaking the contract.

- option gives the holder the right to do something.
- The holder does not have to exercise this right.
• This is what distinguishes options from forwards and futures, where the holder is
obligated to buy or sell the underlying asset.
• Whereas it costs nothing to enter into a forward or futures contract, there is a cost
to acquiring an option.

3.3 Commodity Options
Example: Call Option

Determinants of option premium?

Call option: Volatility

Option valuation
• As a European futures option has the same payoff as a European spot option when the
futures contract matures at the same time as the option, the model used to value
European futures options (lacks model) can also be used to value European spot options.
• However, American spot options and other more complicated derivatives dependent on
the spot price of a commodity require more sophisticated models.
• A feature of commodity prices is that they often exhibit mean reversion (similarly to
interest rates) and are also sometimes subject to jumps.
• Some of the models developed for interest rates can be adapted to apply to commodities.

Option Basics

Implied volatility

3.3 Commodity Options
Example: Seller of Call Option
Risk Analysis: why selling options?
• “Money talks”, get cash premium upfront
− If an API2 option is sold at 10 USD/MT for a tonnage of 75,000 tonnes the total premium
received is $750,000 now
• Long term view underlying market: bearish (sell call), bullish (sell put)
• Long term view volatility:
− An option seller sells option with the view that the volatility will reduce
• Possibility to hedge I arbitrage when linked to physical position
− It is less dangerous for a supplier who is naturally long to sell a call option
• Make sure risk management is in place before selling options
− Nick Leeson at Barings sold straddles and lost $1.4bn
− LTCM the option trader was one of the inventor of the Black Scholes model and he lost $3.7bn

Exercise 12
Question: Suppose you sell a call option contract on April live cattle futures with a strike price of 90cents per pound. Each contract is for the delivery of 40,000 pounds. What happens if the contract is exercised when futures price is 95cents?

Exercise 13
Question: Describe the terminal value of the following portfolio: A newly entered-into long forward contract on an asset and a long position in a European put option on the asset with the same maturity as the forward contract and a strike price that is equal to the forward price of the asset at the time the portfolio is set up.


Exercise 14
Question: A trader buys a call option with a strike price of $45 and a put option with a strike price of $40. Both options have the same maturity. The call costs $3 and the put costs $4. Draw a diagram showing the variation of the trader’s profit with the asset price
