Coffee

A coffee — the world’s second-most-traded commodity by value, derived from roasted coffee beans — is consumed by over 2 billion people daily and supplies a critical morning ritual in developed countries. Coffee prices are highly volatile, driven by frosts in Brazil (world’s largest producer), by El Niño cycles that affect rainfall, and by speculative trading.

The beverage foundation

Coffee is consumed by over 2 billion people globally, making it second only to water in beverage consumption. A typical coffee-drinker consumes 3–4 cups daily, representing steady demand.

This massive consumption, combined with coffee’s role in commerce and culture, makes it a critical commodity and a reliable source of income for millions of small-farm producers in tropical countries.

Brazil’s dominance

Brazil produces 35% of global coffee, primarily from farms in the southern states (Minas Gerais, São Paulo, Espírito Santo). Brazilian coffee is reliable, low-cost, and supplies the world’s largest market (the US and EU).

A Brazilian frost (rare but periodic) can destroy a significant portion of arabica trees and reduce the following year’s production by 20–30%, spiking global prices.

Arabica vs. Robusta split

Coffee comes in two main varieties:

• Arabica (60% of production): Higher quality, more refined flavor, more expensive. Grown in higher altitudes; more susceptible to frost.
• Robusta (40% of production): Higher yield, more bitter, cheaper. More disease-resistant; grown in lower altitudes.

Arabica and Robusta futures trade separately, with Arabica commanding a significant premium.

Commodity price cyclicality

Coffee prices exhibit extreme volatility driven by:

• Brazil frost risk: Occasional frosts destroy yields and spike prices.
• El Niño/La Niña cycles: Affect rainfall in major growing regions (Brazil, Colombia, Indonesia).
• Currency fluctuations: Most coffee is priced in US dollars; currency swings affect producer revenues and planting incentives.
• Speculation: Hedge funds and traders aggressively trade coffee futures, amplifying price moves.

A 20–30% annual price swing is normal; 50%+ moves occur occasionally.

Supply response and boom-bust

High coffee prices incentivize planting; low prices discourage it. However, coffee trees take 3–4 years to mature, creating supply lags.

A period of high prices incentivizes planting, which comes online 3–4 years later, crashing prices. Low prices then discourage new plantings, which again takes years to work through.

This lag creates a boom-bust cycle in coffee prices, frustrating both producers and consumers.

Farmer economics

Coffee is mostly produced by small farmers (~20 million globally) who receive roughly 5–10% of the final retail coffee price. Low farm-gate prices create poverty and incentivize crop abandonment.

High volatility makes planning impossible for farmers; they cannot know whether planting will be profitable 3–4 years hence when the tree matures.

Climate change vulnerability

Climate change poses significant risks to coffee. Rising temperatures in traditional coffee-growing regions (Colombia, Kenya, Ethiopia) could make them unsuitable for coffee cultivation.

Water scarcity is also a risk: coffee requires substantial rainfall and irrigation; a shift to drier climate conditions could reduce yields.

How coffee trades

Arabica futures trade on ICE London and NYBOT (New York) with high liquidity. Robusta futures trade separately on ICE London.

Retail access is via commodity-index funds or specialty agricultural ETFs. Direct futures trading carries significant leverage and is suitable only for experienced traders.

Long-term demand outlook

Coffee consumption is expected to grow 1.5–2% annually with emerging-market growth, particularly in Asia. However, health concerns about caffeine and the shift to decaf in some markets create headwinds.

The long-term structural risk is climate change making traditional coffee-growing regions unsuitable, requiring migration to new regions (higher altitudes, different countries), which would disrupt production.
