Arabica Coffee Prices Decline on Rain Forecasts for Brazil

Coffee prices are mixed, with arabica declining due to forecasts for beneficial rain in Brazil's coffee-growing regions, while robusta reached a 3-week high. Underlying market support stems from critically low ICE inventories, particularly arabica at a 1.5-year low, exacerbated by US tariffs on Brazilian imports tightening US supplies. Despite increased robusta exports from Vietnam, long-term supply concerns, including Brazil's reduced 2025 crop estimates and Volcafe's projection of a fifth consecutive global arabica deficit for 2025/26, continue to underpin the market.

Analysis

Coffee prices are currently mixed, with December arabica futures declining 1.77% due to forecasts of up to 30mm of rain in Brazil's Minas Gerais, which is expected to promote coffee flowering. Conversely, November robusta futures rose 0.55% to a 3-week high, underpinned by critically low global inventories. ICE-monitored arabica stocks have fallen to a 1.5-year low of 525,989 bags, while robusta inventories are at a 2.5-month low of 6,237 lots.

US import tariffs of 50% on Brazilian coffee are significantly tightening US supplies, as American buyers void contracts, with Brazil typically supplying one-third of US unroasted coffee. This geopolitical factor, combined with Brazil's July coffee exports falling 28% and Conab cutting its 2025 arabica crop estimate by 4.9% to 35.2 million bags, provides substantial bullish pressure for arabica.

The long-term outlook presents conflicting signals; while the USDA's FAS projects a 2.5% increase in global coffee production for 2025/26 to a record 178.68 million bags, Volcafe forecasts a widening global arabica deficit of 8.5 million bags for 2025/26, marking the fifth consecutive deficit year. Furthermore, a 71% likelihood of La Niña from October to December poses a significant risk of excessive dry weather for Brazil's 2026/27 crop, potentially exacerbating future supply concerns.

Key Decisions for Investors

• Investors should closely monitor Brazilian weather forecasts for their immediate impact on arabica prices and the long-term implications of La Niña on the 2026/27 crop.
• Evaluate the sustained impact of US tariffs on Brazilian coffee imports, as this policy continues to tighten US supplies and influence global trade patterns.
• Consider the fundamental divergence between arabica, facing potential widening deficits, and robusta, benefiting from increased Vietnamese supply, when constructing coffee-related positions.
• Maintain vigilance on ICE-monitored inventory levels, particularly for arabica, as these critically low figures provide significant underlying market support.
