Arabica Coffee Supported by Limited Rainfall in Brazil

Coffee prices are mixed, with robusta under pressure, falling to a 1.5-week low following a 4.1% year-over-year increase in Vietnam's Jan-Jun exports and USDA forecasts for higher 2025/26 output. Conversely, arabica coffee finds support from forecasts for limited rainfall in Brazil's key growing regions and projected global deficits. However, the broader outlook remains bearish due to advancing Brazilian harvests and the USDA's forecast of record 2025/26 world coffee production and increased ending stocks, signaling ample future supply.

Analysis

The coffee market is currently exhibiting a significant divergence between arabica and robusta futures, driven by conflicting fundamental signals. Robusta prices are under considerable pressure, falling to a 1.5-week low, primarily due to evidence of increased supply from Vietnam, the world's largest producer. This is underscored by a reported 4.1% year-over-year increase in the country's coffee exports for the first half of 2025 and a USDA forecast for a 6.9% rise in Vietnam's 2025/26 output to a four-year high. Conversely, arabica is finding temporary support from forecasts of limited rainfall in Brazil's Minas Gerais region. However, this weather-related strength is set against a broader bearish backdrop for the entire coffee complex. The primary headwind is the advancing Brazilian harvest, which, while slightly behind last year's pace, is in line with the 5-year average, promising imminent supply. The most significant bearish factor is the USDA's June 25 report, which projects record-high world coffee production for 2025/26 at 178.68 million bags and a 4.9% increase in ending stocks, suggesting the market will be well-supplied. While some reports, like Volcafe's, project a continuing arabica deficit, the market appears to be weighing the comprehensive USDA supply forecasts more heavily than past production shortfalls or short-term weather events.

Key Decisions for Investors

• Consider a bearish stance on robusta futures, as strong export data from Vietnam and a bullish USDA production forecast for 2025/26 signal significant supply-side headwinds.
• Exercise caution with long arabica positions; while near-term dry weather in Brazil provides temporary support, the advancing harvest and the USDA's forecast for record global production create a bearish medium-term outlook.
• Monitor the pace of Brazil's coffee harvest against its five-year average and evolving rainfall forecasts, as these are the primary variables currently countering the broader bearish supply narrative.
• Evaluate relative value trades, such as going long arabica versus short robusta, to potentially capitalize on the current divergence driven by Brazil's weather supporting arabica while Vietnamese supply pressures robusta.
