Climate Change Threatens Global Coffee Supply

From your morning cup to your favorite café latte, the price and quality of coffee increasingly hinge on forces outside the roastery—especially the weather. Recent reports warn that a mix of extreme drought, unseasonal heat, and disease outbreaks in key coffee-growing countries could soon send global coffee prices soaring.

The answer is yes—coffee prices are likely to rise significantly, especially over the next year. Brazil, responsible for 40% of the world’s coffee, may see its arabica output fall by as much as 18% this year due to severe drought in Minas Gerais, a major producing state, where rainfall from December through February was just 10% of normal and temperatures were well above average.

Why Global Coffee Production Is Under Threat

Several climate-driven events are converging to threaten coffee supplies. In Central America, a climate-linked disease called leaf rust has severely damaged crops in key growing regions. Meanwhile, Vietnam, the world’s second-largest coffee producer, has cut its forecast for robusta bean harvests—mainly used in instant coffee—due to prolonged drought and unusually cold weather. East African coffee zones are also experiencing critical rainfall shortages.

But the most alarming disruptions are unfolding in Brazil. The country grows roughly 40% of the world’s coffee, with Minas Gerais alone accounting for around 25% of national output. Yet in the state’s usual rainy season months—December, January, and February—rainfall plunged to just 10% of the norm, while temperatures soared. According to the non-profit Coffee & Climate organization, recent weather in Minas Gerais has been highly abnormal, devastating many coffee farms.

How Brazil’s Weather Is Impacting Global Markets

Commodity analysts predict Minas Gerais could see a coffee production drop of up to 35% this year, dragging down Brazil’s overall arabica output by approximately 18%. These losses come at a time when global demand for coffee continues to climb. Adding further risk, many farmers had planted more young coffee trees during recent years of high demand—trees that are especially vulnerable to water shortages. There are also concerns that poor weather could degrade bean quality, not just reduce quantity.

Brazil’s climate has grown increasingly erratic in recent years, with worsening droughts and unstable weather patterns affecting vast growing regions. The latest IPCC report confirms that rising temperatures are likely to reduce global coffee yields across the board.

What This Means for Coffee Prices

Arabica coffee prices on the world market have already climbed to around $2 per pound—nearly double the level of a year ago. However, most consumers won’t see major price hikes immediately. That’s because large coffee chains typically buy beans via futures contracts, locking in prices years in advance. Additionally, traders still hold substantial stockpiles from last year’s bumper harvest. Yet signs suggest that speculators are already moving aggressively into the market.

Frequently Asked Questions

Which country produces the most coffee and how is it affected?

Brazil is the world’s largest coffee producer, responsible for about 40% of global output. In 2024, extreme drought and high temperatures in Minas Gerais—its most important coffee-growing state—led to rainfall levels at just 10% of normal and above-average heat during the key December-to-February rainy season. These conditions are expected to cut Minas Gerais’ output by up to 35% and Brazil’s overall arabica production by around 18%.

How much are coffee prices expected to increase?

Global arabica coffee prices have already nearly doubled over the past year, reaching around $2 per pound. While major buyers often hedge with long-term futures contracts and existing stockpiles may delay price increases for consumers, significant price hikes are likely later in 2024 or early 2025 as those contracts expire and supplies tighten.

What other countries are contributing to the coffee shortage?

Beyond Brazil, Central America is facing widespread leaf rust outbreaks linked to climate change, Vietnam has reduced its robusta crop forecast due to drought and cold, and East Africa is suffering from insufficient rainfall. All of these regions contribute significantly to global coffee supplies and their combined losses are pushing prices upward.

Why are young coffee trees more vulnerable to climate change?

Younger coffee trees, which many farmers planted during recent years of surging demand, have less developed root systems and are less resilient to water stress. During droughts, these immature trees suffer more severe yield losses compared to mature plants, compounding the impact of unfavorable weather on overall production.

Are coffee prices going up right now for consumers?

Not yet. Most coffee retailers purchase beans through futures contracts that lock in prices in advance, often for multiple years. This means the price increases may not immediately affect consumers. However, as those contracts expire and supplies tighten due to lower harvests, retail prices are expected to rise significantly in the near future.
