Coffee Prices: The C-Market and Futures

What the C-market actually measures

The C-market is the market for ICE’s Coffee C futures contract, a benchmark for green, unroasted arabica. It provides a shared reference against which buyers and sellers can negotiate, rather than setting one universal price for every coffee.

A futures contract is a standardised agreement to buy or sell a specified quantity under exchange rules for a particular delivery month. Different months trade separately, so there is no single C-market figure independent of a contract date.

Both coffee benchmarks provide for physical delivery through approved warehouses. Their delivery requirements concern exchange-eligible coffee, not whatever beans a buyer happens to want.

Contract details checked in November 2026. The quotation units are included to explain how these markets work, not to provide current quotations.

When reading a market headline, identify the coffee, contract month and observation date before comparing it with another report. The wider coffee industry includes many transactions that do not resemble an exchange delivery.

Three things often called “the coffee price”

Futures prices

A futures quotation belongs to a particular exchange contract and delivery month. Buyers and sellers trade that contract, establishing a reference through their bids and offers.

Physical prices and differentials

Physical coffee is an actual lot with an origin, quality, quantity and shipment agreement. Its negotiated price may be expressed as:

Agreed futures reference, plus or minus the physical differential, equals the agreed physical price on the stated delivery terms.

The differential connects a standardised benchmark with a particular coffee. It reflects factors such as quality, availability and contractual terms. It can change independently of the futures market.

In a price-to-be-fixed contract, the parties agree the differential first and fix the futures component later under agreed rules. Signing the contract therefore does not necessarily mean the final price has been fixed.

Nor should a negotiated physical differential be confused with the exchange’s prescribed delivery premiums and discounts. Those are rules for coffee delivered against the futures contract.

The ICO Composite Indicator Price

The International Coffee Organization’s ICO Composite Indicator Price, or I-CIP, is a weighted indicator combining Colombian Milds, Other Milds, Brazilian Naturals and Robustas.

It is calculated rather than traded as an ICE futures contract. Its purpose is to describe the broader market, so a movement in the composite is not automatically the same movement as New York arabica or London robusta.

How hedging works

Hedging means taking a financial position intended to offset an existing commercial exposure. The objective is greater certainty, not a winning prediction.

Consider two simplified situations:

• A seller owns coffee that has not yet been sold. Falling prices threaten its value. Selling futures, known as a short hedge, can provide an offset because that position benefits when futures fall.
• A buyer needs coffee that has not yet been purchased. Rising prices threaten its purchasing plans. Buying futures, known as a long hedge, can provide an offset because that position benefits when futures rise.

The physical transaction and futures position must be considered together. A loss on the futures side may accompany an improvement on the physical side, rather than mean the hedge has failed.

Hedging also brings cash-flow demands. Futures positions require margin, funds deposited to support the position, and are marked to market daily. An adverse move can require additional funds before the associated physical benefit is realised.

That is why “the coffee is hedged” does not mean “the business has no financial risk”.

Why coffee markets are volatile

Coffee markets respond to expectations as well as beans already available for shipment. A revised harvest estimate can matter before the crop reaches a warehouse.

Several forces can act together:

• Weather and crop prospects. Heat, drought and disrupted rainfall can alter expected production.
• Available supplies. A forecast recovery does not immediately replace coffee needed for nearby delivery.
• Harvesting and transport. Delays can restrict availability even when coffee has been grown.
• Demand expectations. Changes in buying or consumption prospects affect the expected supply balance.
• Currencies and financial conditions. Exchange-rate movements, access to credit and margin requirements influence trading decisions.
• Trading positions. Buying, selling and the closing of existing positions can interact with changes in the physical market.

The ICO’s November 2024 report, for example, identified a lower Brazilian production forecast, weather-delayed harvesting in Vietnam and shipping disruption among the pressures supporting the market.

A useful question is therefore not simply “Was the harvest good?” but “How did the latest information differ from what traders already expected?”

Recent coffee price movements: 2024 to 2026

The following comparisons use percentage movements, not monetary quotations. Each comparison identifies the series and period because futures, physical indicators and composite averages should not be mixed.

The 2024 to 2025 surge should not be reduced to a single weather event. The World Bank identified lingering effects of an earlier weather-related production shortfall alongside demand growth, and highlighted Brazilian rainfall and temperature risks.

For Vietnam, USDA’s 2024 field reporting documented heat, drought and water stress. That provides firmer support than a blanket claim that Vietnamese typhoons caused the robusta surge.

The September 2026 ICO report described easing as Brazil’s record crop reached the market. It also noted that low certified arabica stocks provided some support, illustrating how a larger crop and nearby supply constraints can coexist.

As checked on 2 November 2026, September 2026 was the latest monthly report available on the ICO report page retrieved for this article. This account therefore does not attribute developments to an unverified October report or treat the remainder of 2026 as settled history. Follow market trends for the broader changing picture.

What this means for farmers and shoppers

Farmers do not receive the screen quotation

The futures benchmark is not a farmgate payment. Farmers may sell cherries, parchment or green coffee through different local arrangements, while processing, transport, quality and the organisation of the supply chain affect what reaches them.

Higher benchmarks can improve selling opportunities without guaranteeing higher household income. A producer may already have sold coffee, have less crop available after adverse weather, or face increased production expenses.

The relationship between benchmarks and livelihoods needs more than an exchange chart. Farmgate prices and farmer income examines that distinction in detail.

Retail changes are neither immediate nor identical

A supermarket bag includes more than green coffee: processing, roasting, packaging and distribution also contribute to the final product. Existing stocks and purchasing arrangements further complicate the link between a market movement and a shop shelf.

USDA research on the US coffee industry found that changes in commodity inputs passed through over time rather than immediately and completely. That is evidence about a historical US market, not a numerical forecasting rule for British retailers.

For a UK workplace, the practical response is to request an itemised written quotation and ask when coffee supply terms can change. Separate the beans from delivery, equipment, servicing and other elements so that a market explanation can be assessed on its own merits.

The deeper issue: what a hedge leaves uncovered

A futures hedge principally addresses movement in its benchmark. Basis risk is the risk that the relationship between that benchmark and the particular physical coffee changes.

For example, a shortage of a specific origin or quality can strengthen its differential even while the broader benchmark falls. The buyer’s actual coffee may consequently behave differently from the contract used to hedge it.

Delivery timing matters too. A hedge tied to one futures month may not match the date on which the physical coffee is bought or sold.

For readers assessing a supplier’s explanation of coffee prices, use this short checklist:

1. Name the reference: arabica, robusta or an ICO indicator?
2. Match the period: which contract month, observation date or monthly average?
3. Separate the components: benchmark movement, physical differential or another supply-chain expense?
4. Check what is fixed: the complete physical agreement, or only its differential?
5. Ask what remains exposed: currency, quality, shipment timing or contract revision?

These questions make the C-market and futures useful explanatory tools without mistaking them for a complete account of every coffee purchase.
