Coffee Prices Surge on Brazil Crop Concerns and Tighter US Supplies

September arabica and robusta coffee futures extended their two-week rally today, reaching multi-month highs with gains of +3.40% and +2.13% respectively. This surge is primarily driven by acute supply concerns, including drought and frost damage in Brazil's key coffee regions, significant year-over-year declines in Brazilian exports, and tighter U.S. supply due to new tariffs. Further upward pressure stems from falling ICE arabica and robusta inventories and reduced production from Vietnam, contributing to a projected widening global arabica deficit for 2025/26.

Analysis

Coffee futures have extended a significant two-week rally, with arabica (KCU25) and robusta (RMU25) reaching 2.5-month and 2.75-month highs, respectively, on the back of compounding supply-side pressures. The primary catalyst is adverse weather in Brazil, specifically a lack of rain in the key Minas Gerais region and recent frost damage, which has sparked aggressive fund buying. This is exacerbated by a sharp decline in Brazilian exports, with July unroasted coffee shipments falling 20.4% year-over-year and green coffee exports dropping 28% y/y, according to Cecafe. Further tightening the market, particularly in the US, are new 50% tariffs on Brazilian beans causing American buyers to void contracts. Supply concerns are also emanating from Vietnam, where drought led to a 20% y/y production decrease for the 2023/24 crop and a 17.1% y/y drop in 2024 exports. These fundamental shortages are reflected in declining inventories, with ICE-monitored arabica stocks hitting a 1.25-year low. However, several bearish factors temper this outlook, including the near-completion of Brazil's current harvest at 94% as of August 6, slightly ahead of last year's pace. More significantly, a major divergence exists in future outlooks: the USDA's FAS projects a record world coffee production for 2025/26, up 2.5% y/y, while private forecaster Volcafe projects a widening arabica deficit for the fifth consecutive year, creating significant market uncertainty.

Key Decisions for Investors

• Given the confluence of severe supply shocks in Brazil and Vietnam driving prices to multi-month highs, investors could consider maintaining long positions to capture continued near-term momentum.
• Traders should closely monitor Brazilian harvest completion reports and any updates to global production forecasts, as the USDA's projection of a record 2025/26 crop presents a significant headwind that could trigger a sharp price reversal.
• The stark divergence between the USDA's forecast for a record supply and Volcafe's projection of a widening arabica deficit suggests heightened future volatility, making it prudent to use options or other hedging instruments to manage risk.
