Arabica Coffee Erases Early Gains on Hopes of Progress in Brazil Tariff Talks

Coffee prices closed mixed, with robusta climbing to a one-month high while arabica declined amidst speculation of a potential suspension of 50% tariffs on Brazilian exports. Arabica prices are supported by critically low ICE inventories, exacerbated by these tariffs, and concerns over dry weather in Brazil's key growing regions, leading Volcafe to project a widening arabica deficit. Conversely, robusta faces pressure from favorable weather and increased export projections from Vietnam, contributing to USDA FAS forecasts of record global coffee production in 2025/26, despite the arabica supply tightness.

Analysis

Arabica and robusta coffee futures exhibited divergent performance, with December arabica (KCZ25) closing down 0.28% while November robusta (RMX25) gained 1.59% to a one-month high. Arabica's decline was partly driven by speculation regarding a potential suspension of 50% tariffs on Brazilian exports following a US-Brazil meeting.

Despite this, arabica prices are underpinned by significant supply concerns. ICE-monitored arabica inventories have fallen to a 1.5-year low of 493,783 bags, exacerbated by the 50% tariffs on Brazilian imports which are causing American buyers to void contracts and tighten US supplies. Furthermore, severe dry conditions in Brazil's Minas Gerais, receiving only 48% of its historical average rainfall, and a 71% likelihood of La Niña, threaten the 2026/27 crop. Conab recently cut Brazil's 2025 arabica crop estimate by 4.9% to 35.2 million bags, and Volcafe projects a widening global arabica deficit of 8.5 million bags for 2025/26, marking a fifth consecutive deficit year.

Conversely, robusta coffee faces bearish pressures from robust supply. Vietnam, the world's largest robusta producer, anticipates above-average rainfall through October 20, supporting crop development and yields, with Dak Lak province expecting 70mm of rain. This favorable weather contributes to a projected 6% year-over-year increase in Vietnam's 2025/26 robusta production to a four-year high of 1.76 MMT, alongside a 10.9% year-over-year rise in Jan-Sep 2025 exports.

The USDA FAS forecasts a 2.5% increase in world coffee production for 2025/26 to a record 178.68 million bags, driven by a 7.9% rise in robusta output, even as arabica production is expected to decrease by 1.7%. This suggests a continued divergence in supply dynamics between the two coffee varieties.

Key Decisions for Investors

• Monitor US-Brazil tariff negotiations closely, as any resolution could significantly impact arabica supply dynamics and price volatility.
• Consider the widening arabica deficit, driven by low inventories and adverse Brazilian weather, as a potential bullish catalyst for arabica futures.
• Evaluate robusta positions in light of projected bumper crops and increased exports from Vietnam, which suggest continued ample supply.
• Track global coffee inventory levels and regional weather patterns, particularly La Niña's impact on Brazil, for ongoing supply-demand imbalances.
