Coffee economics and price formation

Four things called the coffee price

Sourced

The trade handbook's own list.

An outright price

A fixed sum agreed for a physical coffee: so many cents a pound for this lot. The handbook says the highest-quality coffees are mainly traded this way.

A futures price plus a differential

The price is left open and tied to an exchange contract, plus or minus an agreed difference for this coffee. The handbook says almost all business on a differential is done against the futures markets.

The futures price itself

The price of a standard contract on the exchange in New York for arabica or London for robusta. This is the number newspapers report.

An indicator price

A published average. The International Coffee Organization collects prices for four groups of coffee and combines them into a composite indicator, which the handbook describes as a weighted average of all major origins and types.

The New York contract, as the exchange states it

Sourced

Read on the exchange's own page on 8 October 2026. A point is a hundredth of a cent, so 1,000 points is ten cents a pound.

These are the exchange's rules on the date read, and they change: the 2021 trade handbook prints a different table, with Colombia at a 400-point premium and Costa Rica, Kenya and Guatemala at the contract price. Nothing here is a current market price.

What the contract is, and what it is not

Sourced

The New York contract is a promise to deliver or accept a standard quantity of arabica of a certified grade at a named warehouse in a named month. The handbook lists the delivery months as March, May, July, September and December, and says coffee tendered against it is examined by a panel of three licensed graders, who know the country of origin but not whose coffee it is, for odour, bean size, colour, defects, evenness of roast and cup.

The London contract does the same job for robusta. The handbook gives its unit as 10 tonnes, quoted in dollars a tonne, and dates robusta futures in London to 1958.

Neither is a price list for real coffees. They are benchmarks, and the handbook's own table shows how far trading in them exceeds the coffee that exists: in 2019 the New York contracts traded were equivalent to about 4.1 billion bags against a world arabica crop of 92 million. Hedgers and speculators both trade them, and the handbook says it is not uncommon for speculative funds to hold a fifth to a quarter of the open positions.

The differential: how a real coffee is priced against it

Sourced

A physical coffee is worth more or less than the standard grade the contract is written for, and the differential is that difference. A price clause, in the handbook's example, reads New York C December plus or minus three cents a pound. The differential reflects the coffee's quality and availability, the terms of sale and the local currency.

Differentials move on their own. The handbook's example is a standard Colombian grade that traded at about fifteen cents over New York and rose sharply in 2010 to eighty cents over; a trader who had sold at fifteen and had to buy at eighty lost sixty-five cents a pound before the futures price was even fixed. It says differentials are usually lower when futures are high and higher when they are low, and that no mechanism exists to hedge them.

Selling now, pricing later

Sourced

A large share of physical coffee is sold with the price still open. The contract fixes the coffee, the quantity, the shipping month, the futures month and the differential, and says which side has the right to choose the moment the futures price is taken. The handbook describes the advantage as separating two decisions: securing the coffee, and fixing what it costs.

Who holds that right matters, and one certifier writes it into its rules. The Fairtrade coffee standard, in the version dated July 2021, requires its buyers to agree a price-to-be-fixed contract with the producer organisation with the fixing at the producers' call, and allows a fixed price only in listed cases, such as where the coffee is already in stock or where both sides agree a way of managing the risk in writing.

From the port back to the farm

Sourced

The price free on board at the port is not the price at the farm gate, and the handbook warns that comparing a retail price with a farm price is misleading without the costs between. It reports one attempt to measure the gap: export prices gathered by interview with importers and exporters in late 2020, set beside farm-gate prices from surveys of more than 10,000 farmers.

Its worked example sets a micro-lot of Ethiopian natural arabica, at 8.80 US dollars a kilogram free on board in late 2020, beside Brazilian natural arabica at 2.13. The share reaching the farm was 46 per cent for the first and 89 per cent for the second. The handbook gives several reasons at once and does not weigh them: micro-lots are scarcer, and cost more to produce and to sell, and the two chains are built differently, with Brazilian farms larger and often processing their own coffee while Ethiopian smallholders' coffee is gathered with other farmers' before processing, which adds cost. It reads a high share as the sign of an efficient chain. That is its interpretation of a ratio; the figures are prices and not farm incomes.

It also warns against reading too much into the comparison. A farmer who sells a micro-lot may sell only 5 to 10 per cent of the crop that way, and the rest at ordinary prices, so the farm's real price is an average across all of them.

What a quality premium looks like in real contracts

Sourced

One research team publishes prices from contracts that companies donate. Its 2020 analysis covered about 30,000 contracts for specialty coffee with a quality score, from the harvests of October 2016 to September 2019, three seasons in which the New York price fell from an annual average of 1.40 US dollars a pound to 1.01.

In that sample, for 2016 to 2019, the median price free on board for coffee with no certification was 3.00 US dollars a pound, and for coffee certified both Fairtrade and organic it was 2.20. The two groups were different coffees, and the authors say so: certified contracts were on average about twice the size, and certification was roughly three times as common among coffees scoring under 84 points and among lots of more than 40,000 pounds. Weighted by volume, the average for certified coffee in 2016 to 2019 was 2.41 US dollars a pound, 24 cents above uncertified. The medians do not show that certifying a coffee lowers its price.

At the bottom of the 2016 to 2019 sample the lowest twentieth of certified contracts paid 1.90 US dollars a pound, the mandated minimum for such coffee in those years, which was 55 cents above the same point for uncertified coffee. At the top, the highest twentieth of uncertified contracts reached 6.86 against 3.30. The authors read this as a floor that protects cheaper coffees sold in large lots, where they put its worth at about 80 cents a pound, and that matters little for small lots of high-scoring coffee, which sold for more outside the scheme.

They say two things about their own data that bear repeating. Their 57 donors were not necessarily representative of buyers, and a price free on board does not show how much reaches a farm. A trade report of the team's 2024 edition gives 123 companies and more than 100,000 contracts, with a median of 3.48 US dollars a pound over the most recent three harvests; that edition was not opened for this page.

Costs, living income and why a premium need not reach the grower

Sourced

A living income is defined, in the wording the handbook quotes from the body that maintains the idea, as the net income a household in a particular place needs to afford a decent standard of living for all its members. It is a benchmark calculated place by place, not one figure, and the handbook names one methodology as the most widely adopted for calculating it.

Whether a price meets it depends on cost as much as on price. CoffeeHQ's country entries show how different costs are: in Colombia picking is about half of the cost of growing coffee, on the figures its entry cites, while its entry on Brazil describes harvesting by machine on the farms where the land allows it.

A certified premium is also paid only on coffee sold as certified. The handbook cites an industry report for the figure that in 2019 less than a quarter of the coffee grown under voluntary sustainability standards was bought as such; the rest was sold as ordinary coffee, by growers who had already paid to comply.

Why prices swing

Sourced

The handbook's list of what moves green coffee prices is short: the quality and availability of a coffee at a given moment, weather, market expectations, speculation and currencies. It adds that activity on the futures markets has itself made prices more volatile, often unrelated to the supply of coffee.

Supply has its own rhythm as well. Brazil's crop, the largest, alternates between heavier and lighter years, which CoffeeHQ's entry on Brazil describes from the United States Department of Agriculture's reports. The handbook's chart of prices since 1989 marks a Brazilian frost in 1994 and Brazilian droughts in 1999 and 2014 beside three of its peaks.

Prices and incomes this page does not give

CoffeeHQ explanation

It gives no current price for coffee, on any exchange or for any origin. Prices change every trading day, and the figures above are dated because each was true only then.

It gives no farm income, no cost of production for any country beyond what CoffeeHQ's own country entries cite, and no living-income benchmark for any place. It does not say that specialty coffee pays farmers more: the one dataset read shows higher median export prices in 2016 to 2019 and says itself that it cannot see the farm.

The handbook's table of farm-gate and export prices is misprinted in the published file, with percentages where the prices should be, so only the two countries its text spells out appear here. The International Coffee Organization's own reports on prices and incomes were not opened.

Nothing here is financial, trading or investment advice.
