A Guide to the Language of the Futures Industry
Implied Repo Rate: The rate of return that can be obtained from selling a debt instrument futures contract and simultaneously buying a bond or note deliverable against that futures contract with borrowed funds. The bond or note with the highest implied repo rate is cheapest to deliver.
Index Arbitrage: The simultaneous purchase (sale) of stock index futures and the sale (purchase) of some or all of the component stocks that make up the particular stock index to profit from sufficiently large intermarket spreads between the futures contract and the index itself. Also see Arbitrage, Program Trading.
Indirect Bucketing: Also referred to as indirect trading against. Refers to when a floor broker effectively trades opposite his customer in a pair of non-competitive transactions by buying (selling) opposite an accommodating trader to fill a customer order and by selling (buying) for his personal account opposite the same accommodating trader. The accommodating trader assists the floor broker by making it appear that the customer traded opposite him rather than opposite the floor broker.
Inflation-Indexed Debt Instrument: Generally a debt instrument (such as a bond or note) on which the payments are adjusted for inflation and deflation. In a typical inflation-indexed instrument, the principal amount is adjusted monthly based on an inflation index such as the Consumer Price Index.
In Position: Refers to a commodity located where it can readily be moved to another point or delivered on a futures contract. Commodities not so situated are "out of position." Soybeans in Mississippi are out of position for delivery in Chicago, but in position for export shipment from the Gulf of Mexico.
In Sight: The amount of a particular commodity that arrives at terminal or central locations in or near producing areas. When a commodity is "in sight," it is inferred that reasonably prompt delivery can be made; the quantity and quality also become known factors rather than estimates.
Interest Rate Futures: Futures contracts traded on fixed income securities such as U.S. Treasury issues, or based on the levels of specified interest rates such as LIBOR (London Interbank Offered Rate). Currency is excluded from this category, even though interest rates are a factor in currency values.
Interest Rate Swap: A swap in which the two counterparties agree to exchange interest rate flows. Typically, one party agrees to pay a fixed rate on a specified series of payment dates and the other party pays a floating rate that may be based on LIBOR (London Interbank Offered Rate) on those payment dates. The interest rates are paid on a specified principal amount called the notional principal.
Intermediary: A person who acts on behalf of another person in connection with futures trading, such as a futures commission merchant, introducing broker, commodity pool operator, commodity trading advisor, or associated person.
International Swaps and Derivatives Association (ISDA): A New York-based group of major international swaps dealers, that publishes the Code of Standard Wording, Assumptions and Provisions for Swaps, or Swaps Code, for U.S. dollar interest rate swaps as well as standard master interest rate, credit, and currency swap agreements and definitions for use in connection with the creation and trading of swaps.
In-The-Money: A term used to describe an option contract that has a positive value if exercised. A call with a strike price of $1100 on gold trading at $1150 is in-the-money 50 dollars. See Intrinsic Value.
Intrinsic Value: A measure of the value of an option or a warrant if immediately exercised, that is, the extent to which it is in-the-money. The amount by which the current price for the underlying commodity or futures contract is above the strike price of a call option or below the strike price of a put option for the commodity or futures contract.
Introducing Broker (IB): A person (other than a person registered as an associated person of a futures commission merchant) who is engaged in soliciting or in accepting orders for the purchase or sale of any commodity for future delivery on an exchange who does not accept any money, securities, or property to margin, guarantee, or secure any trades or contracts that result therefrom.
Inverted Market: A futures market in which the nearer months are selling at prices higher than the more distant months; a market displaying "inverse carrying charges," characteristic of markets with supply shortages. See Backwardation.
Invisible Supply: Uncounted stocks of a commodity in the hands of wholesalers, manufacturers, and producers that cannot be identified accurately; stocks outside commercial channels but theoretically available to the market. See Visible Supply.
Invoice Price: The price fixed by the clearing house at which deliveries on futures are invoiced—generally the price at which the futures contract is settled when deliveries are made. Also called Delivery Price.
Knock-In: A provision in an option or other derivative contract, whereby the contract is activated only if the price of the underlying instrument reaches a specified level before a specified expiration date.
Knock-Out: A provision in an option or other derivative contract, whereby the contract is immediately canceled if the price of the underlying instrument reaches a specified level during the life of the contract.
