Arabica Coffee Prices Retreat on Brazil Rains and Tariff Talks

Arabica coffee futures declined from a 4-week high, primarily due to updated rain forecasts for Brazil's coffee-growing regions and subsequent liquidation, despite earlier concerns over severe dry conditions and tightening ICE inventories exacerbated by US tariffs on Brazilian imports. Conversely, robusta coffee futures advanced, though a projected bumper crop and increased exports from Vietnam, coupled with overall rising global coffee production forecasts for 2025/26, indicate potential supply increases. The market presents a mixed outlook, with some analysts projecting a widening global arabica deficit for 2025/26, while robusta supply appears robust.

Analysis

Arabica coffee futures declined 1.19% on Wednesday, retreating from a 4-week high, primarily due to updated rain forecasts for Brazil's coffee-growing regions, sparking liquidation. This reversal occurred despite earlier concerns over severe dry conditions in Minas Gerais, receiving only 48% of historical average rainfall, and tightening ICE-monitored arabica inventories, which fell to a 1.5-year low. Further pressure stems from 50% US tariffs on Brazilian imports, leading American buyers to void contracts and exacerbating US supply tightness.

Conversely, November robusta coffee futures advanced by 1.23%, supported by overall market dynamics but facing bearish pressures from robust supply forecasts. Vietnam, the world's largest robusta producer, anticipates above-average rainfall, supporting a projected 6% year-over-year increase in its 2025/26 coffee production to a 4-year high of 1.76 MMT. Additionally, Vietnam's Jan-Sep 2025 coffee exports surged 10.9% year-over-year to 1.230 MMT, contributing to adequate global supplies as indicated by the ICO's +0.2% rise in global exports.

The coffee market presents a mixed outlook, characterized by a fundamental divergence between arabica and robusta. While the USDA FAS projects a 1.7% decrease in 2025/26 arabica production, Volcafe forecasts a widening global arabica deficit of 8.5 million bags for 2025/26, marking the fifth consecutive year of deficits. This contrasts with a projected 7.9% increase in robusta production and a 2.5% rise in overall world coffee production for 2025/26, suggesting robusta supply could partially mitigate global deficits.

Key Decisions for Investors

• Monitor weather developments in Brazil and Vietnam closely for their impact on arabica and robusta supply, respectively
• Evaluate the ongoing impact of US tariffs on Brazilian coffee, which are tightening US arabica supplies and influencing pricing dynamics
• Consider a bifurcated strategy, potentially favoring long-term arabica exposure due to projected deficits while exercising caution on robusta given robust supply forecasts
• Track global inventory levels and export data, particularly ICE-monitored stocks and Vietnam's export figures, for further supply-demand signals
