Coffee Prices Jump on Climate Worries

Prices for two key coffee types shot up this week after Japan’s weather agency announced the return of El Niño across the Pacific Ocean. Traders scrambled to cover their bets after months of gloomy forecasts about bumper harvests turned suddenly uncertain. The sudden shift shows how quickly markets react when climate patterns threaten food supplies that rely on steady weather. Brazil, the world’s top coffee grower, has been flooding the market with promises of record harvests. Analysts kept raising estimates for next year’s crop, expecting up to 76 million bags—enough to fill more than 1, 100 Olympic swimming pools with beans. But those predictions assume normal rainfall, something El Niño could cancel out by delaying Brazil’s crucial spring rains. Without timely showers, coffee trees won’t flower properly, and next year’s beans might never reach their full potential. Vietnam, the second-biggest coffee producer, isn’t helping prices either. The country’s exports surged nearly 8% in the first five months of this year, adding to a 17% jump last year. Most of that is low-cost robusta, which competes directly with Brazil’s arabica. When Vietnam floods the market, global prices feel the squeeze—until supply scares kick in.Behind the scenes, coffee stockpiles are shrinking fast. Warehouses monitored by ICE, the commodities exchange, now hold barely 400, 000 arabica bags—the lowest since last fall. Robusta stocks dropped to two-year lows before bouncing slightly. Smaller inventories usually mean higher prices, but traders know big harvests could erase those gains quickly. Shipping headaches add another layer of cost. The Strait of Hormuz, a vital route for Middle Eastern oil and global goods, has been partially blocked. That forces ships to take longer, pricier detours around Africa, pushing up transport, insurance, and fuel bills for everyone from farmers to cafes. When every link in the chain gets more expensive, coffee drinkers worldwide feel it in their wallets. Not everyone is worried. The International Coffee Organization reported a tiny dip in global exports for the year, but analysts still expect 2025’s harvest to set a new record. Brazil’s crop might even shrink a bit because of older trees and changing weather, while Vietnam’s robusta fields keep expanding. The result? A looming surplus of lower-priced robusta and scarcer, pricier arabica. What happens next depends on El Niño’s strength. Forecasters give it a two-thirds chance of becoming a “Super El Niño, ” potentially the strongest in decades. If rains fail in Brazil or floods damage Asian farms, prices could spike again. If the harvests meet the hype, the recent rally might fade as quickly as it began.
