Market Terms
Reading a price correctly
A price is never just a number. It refers to a delivery point, a quality, a period, a lot size, and a contract, and a reader who does not know which of those is meant has not read the price at all. This section defines the vocabulary that surrounds agricultural price information so that figures obtained elsewhere can be understood for what they are.
Definitions, not quotations
AgricultureID carries no market data. That is a design decision, not a gap. A price is meaningful for as long as it is current, and a reference site that published one would be publishing something stale and passing it off as information. Instead, these pages define the terms — and readers take those definitions to whichever exchange, reporting service, or agency actually holds the figures.
A definition never requires a number. No entry here illustrates a term with an invented figure, because an illustrative number on a page a reader may mistake for market information is worse than no page at all.
The confusions are the point
Most of these terms have a near neighbour they are routinely mistaken for, and the mistake is usually expensive. Every entry states explicitly what it is not to be confused with — the distinction is treated as a required part of the definition rather than a nicety.
The underlying trade mechanics — how a delivery point, a set of obligations, or a documentary requirement comes about — are described under trade concepts. The physical conditions that a quality specification refers to are described under quality attributes and grading standards.
What these pages are not
AgricultureID publishes no live prices, no price forecasts, and no trading signals. This page defines a term so that price information obtained elsewhere can be read correctly. Nothing here is investment, hedging, or trading advice, and no figure on this page should be used as a current market quotation.
Market terms A–Z
Each entry gives the definition, where the term is used, what it is not to be confused with, the commodities it applies to, and the related terms and trade concepts it depends on.

- Market term
Basis
Basis is the difference between the cash price for a physical lot at a particular place, time, and quality and the futures or reference price it is quoted against. It is not a market of its own — it is the arithmetic gap between two quotations that describe different things.
- Market term
Benchmark Price
A benchmark price is a particular market quotation that convention has elevated into the common anchor other prices are quoted against. Being a benchmark is a role a price acquires through use, not a property it has by construction — and the role is granted by the market, not by any authority.
- Market term
Cash Market
The cash market is where physical commodities are actually bought and sold — real lots, at real places, changing hands between parties who want the goods. It is not one market but a vast set of local ones, which is why it has no single price and no single venue.
- Market term
Composite Indicator Price
A composite indicator price is a single figure calculated by an organisation from several underlying market quotations according to a published methodology, in order to represent a market that has no single price. It is a constructed measure of a market, not a price anyone paid.
- Market term
Contango and Backwardation
Contango and backwardation name the two shapes a market’s forward structure can take: deferred delivery periods priced above nearer ones, or below them. They describe a structure that exists now — they are not forecasts, and the words carry no view about the future.
- Market term
Crush Spread
A crush spread is the difference between the quoted price of an oilseed and the combined quoted prices of the products it yields, weighted by a conversion assumption. It is a relationship between quotations — not a processor’s margin, and not a measure of anyone’s profitability.
- Market term
Deferred Pricing
Deferred pricing is an arrangement in which a commodity is delivered now and the price is set later, by a mechanism the contract specifies. It separates the physical transaction from the pricing decision — and in doing so it changes what the seller is exposed to, rather than removing exposure.
- Market term
Forward Contract
A forward contract is a privately negotiated agreement to deliver a specified commodity at a future date on terms the parties set themselves. Everything about it is negotiable — which is its advantage over a futures contract, and simultaneously the source of every difficulty it creates.
- Market term
Freight Parity
Freight parity is the price at one location implied by the price at another once the cost of moving the commodity between them is accounted for. It is a calculated comparison — a way of asking what a distant price means here — and not a price anyone quotes or pays.
- Market term
Futures Contract
A futures contract is a standardised, exchange-traded agreement to buy or sell a specified quantity and quality of a commodity at a future date, with performance guaranteed by a clearing house rather than by the counterparty. Its defining feature is standardisation — everything except the price is fixed in advance.
- Market term
Hedging
Hedging is taking a market position intended to offset an exposure a party already has, so that a loss on one is met by a gain on the other. It is defined by the purpose and by the pre-existing exposure — not by the instrument used, and not by whether it turns out well.
- Market term
Liquidity
Liquidity is the ease with which a party can transact without materially moving the price against themselves. It is a multi-dimensional property of a market rather than a quantity, and its most important characteristic is that it is not constant — it tends to be least available exactly when it is most needed.
- Market term
Market Depth
Market depth is the quantity available to transact at or near the prevailing price. It is one dimension of liquidity — the size dimension — and it answers a narrow question: how much can move before the price does.
- Market term
Minimum Price
A minimum price is a floor below which a buyer under a given scheme or rule may not pay, regardless of what the market does. It is an obligation created by an instrument, not a price the market formed — and it binds only those the instrument reaches.
- Market term
Origin Differential
An origin differential is the price difference attached to a commodity because of where it was produced, relative to another origin or a common reference. It prices the origin as a bundle — quality character, reliability, documentation, and logistics together — rather than any single measurable attribute.
- Market term
Premium and Discount
A premium is an addition to a price and a discount a deduction from it, applied for a stated reason against a stated basis. They are attributed adjustments — which is what separates them from a basis or a spread, where the gap is a composite with no single cause.
- Market term
Price Discovery
Price discovery is the process by which the interaction of buyers and sellers produces a price that expresses what participants collectively know and believe. It names a process, not a number — and the price it produces is an output of that process, not a measurement of an underlying true value.
- Market term
Price Index
A price index is a computed statistic expressing how prices have changed relative to a base period, aggregated across items by a weighting scheme. It measures relative change rather than level, and its construction — base, basket, and weights — determines what it says.
- Market term
Price Volatility
Price volatility is a measure of how much a price has varied over a period. It measures variation and nothing else — not direction, not risk, and not what will happen next — and it is always the product of a measurement choice that the resulting figure conceals.
- Market term
Quality Premium
A quality premium is the additional amount a buyer pays for a measured quality attribute above a stated specification. It prices a property the buyer can use — which is why a premium exists only where the attribute is measurable, verifiable, and commercially valuable to that particular buyer.
- Market term
Reference Price
A reference price is whatever figure a contract, formula, or rule points to as the anchor for determining another price. It is defined by the role it is given rather than by how it was produced — which is why a reference price may be a market quotation, a computed index, or a number an authority fixed.
- Market term
Speculation
Speculation is taking a market position without holding an underlying exposure to offset — accepting price risk in order to profit from price movement. It is the structural counterpart of hedging: a hedger transfers risk, and someone must be there to receive it.
- Market term
Spot Price
A spot price is the price for a commodity available for immediate or near-immediate delivery, for a specific lot at a specific place and quality. It is the price of something that exists now — which is what separates it from every price for something that will exist later.
- Market term
Spread
A spread is the difference between two prices for related but distinct things — two delivery months, two commodities, two markets, or a bid and an offer. The word names an arithmetic operation, so what any particular spread means depends entirely on what two prices it subtracts.
- Market term
Stocks-to-Use Ratio
The stocks-to-use ratio relates the stocks remaining at the end of a marketing year to the quantity used during it, expressing the buffer as a proportion of consumption. It is a compact measure of adequacy — and it inherits every weakness of the two balance sheet items it is built from.
- Market term
Supply and Demand Balance Sheet
A balance sheet accounts for a commodity over a marketing year: what was available, what was used, and what remains. It is an accounting identity that must balance by construction — which is why the item that makes it balance is the one carrying all the uncertainty.
