Coffee C Futures: The Global Arabica Benchmark

Key Takeaways

• Coffee C is the global price benchmark for washed arabica, traded on ICE in 37,500 pound lots.
• One tick of 5/100 cent per pound equals 18.75 dollars per contract on the 37,500 pound size.
• Treating the C price as a flat farmgate price ignores origin differentials and quality premiums.
• Weather in Brazil and Colombia drives most of the volatility, so frost and drought headlines move the curve fast.

What It Is

The arabica coffee C futures contract trades on ICE Futures U.S. under the symbol KC. Each contract covers 37,500 pounds of washed arabica green coffee, roughly 250 standard bags. Settlement is by physical delivery of exchange grade beans into licensed warehouses at named ports in the United States and Europe.

Prices are quoted in U.S. cents per pound. The minimum price move, called a tick, is 5/100 of one cent per pound, which works out to 18.75 dollars per contract. Trading is limited to the March, May, July, September, and December delivery months.

The Intuition

Coffee is grown in dozens of countries with different climates, altitudes, and processing styles. Without a common reference price, every buyer and seller would have to negotiate from scratch. The C contract solves that by defining one standard grade and one set of delivery rules, then letting the market discover a single number.

That number becomes the spine of the physical trade. A Colombian exporter and a German roaster rarely transact at the flat C price. Instead they agree on a differential, such as the C price plus 30 cents, that reflects the origin, quality, and certification of the actual lot. The C contract handles the broad market direction, and the differential handles everything specific to that coffee.

How Arabica Coffee C Futures Work

The contract permits delivery of washed arabica from a list of roughly 20 origin countries. Each origin carries a fixed premium or discount to the contract price set in the ICE rulebook. Colombia, Costa Rica, and Kenya deliver at a premium, while Brazil delivers at a discount, reflecting cup quality and historical supply.

Effective price for a lot = C futures price + origin differential + quality differential

A delivery is graded by ICE before it can be tendered. Inspectors score the beans for defects and run a cup test for flavor. Coffee that grades above the standard earns a premium, and coffee that grades below it takes a discount or is rejected. This grading step is what keeps the deliverable supply honest and the futures price meaningful.

Because arabica is sensitive to cold and drought, the supply side is concentrated and weather driven. Brazil and Colombia together dominate washed and natural arabica output, so a frost in Minas Gerais or a dry stretch in the Colombian highlands can lift the whole curve within days.

Worked Example

Suppose the front month arabica coffee C contract trades at 320 cents per pound. One contract represents 37,500 pounds, so its notional value is:

320 cents x 37,500 lb = 12,000,000 cents = 120,000 dollars

Now imagine a roaster who needs to buy 375,000 pounds of green coffee in three months and wants to lock the price. That is 10 contracts. If the market rises 20 cents before the roaster buys physical beans, the futures position gains:

20 cents x 37,500 lb x 10 contracts = 7,500,000 cents = 75,000 dollars

That futures gain offsets most of the higher price the roaster now pays in the cash market. The hedge does not capture the origin differential, which still moves on its own, but it removes the bulk of the flat price risk.

Common Mistakes

1. Confusing the C price with the farmgate price. Growers receive the C price adjusted by differentials and local costs, not the headline screen number. The gap can be large.

2. Ignoring the deliverable origin list. Brazil trades at a discount to the contract, so a Brazil heavy supply picture can keep the C price soft even when demand looks firm.

3. Underestimating weather risk. Arabica is concentrated in a few growing regions. A single frost event can move the contract limits for several sessions.

4. Treating arabica and robusta as one market. They are separate contracts on separate exchanges with their own supply stories. The spread between them shifts with relative scarcity.

5. Holding into delivery by accident. Physical delivery is real. Speculators who do not roll or close before first notice can be assigned warehouse receipts they never wanted.
