Tariff Turmoil Weighs on Coffee Prices

Coffee prices are under pressure, with September arabica and robusta down, driven by concerns over potential U.S. tariffs on Brazilian exports, accelerated harvest progress in Brazil, and rising robusta inventories alongside record fund short positions. While the USDA forecasts a record 178.68 million bags for global 2025/26 coffee production, signaling ample supply, this is countered by a projected 8.5 million bag arabica deficit by Volcafe for the same period, marking the fifth consecutive year of arabica shortfalls, and declining arabica inventories to a 14.5-month low.

Analysis

The coffee market is currently facing significant bearish pressure, reflected in the price declines for both September arabica (-1.77%) and robusta (-0.38%). This is primarily driven by macro supply forecasts and geopolitical risks. The USDA's Foreign Agricultural Service (FAS) projects a record global coffee production of 178.68 million bags for 2025/26, a 2.5% year-over-year increase fueled by a substantial 7.9% rise in robusta output. This outlook is compounded by the rapid pace of Brazil's ongoing harvest, which is tracking ahead of both last year's level and the five-year average, and the looming threat of a potential 50% U.S. tariff on Brazilian coffee. However, the market presents a bifurcated picture. While robusta fundamentals appear weak, with ICE-monitored inventories at a one-year high and fund net-short positions reaching a two-year peak, the arabica market shows signs of tightening. Contradicting the USDA, Volcafe forecasts a widening arabica deficit of 8.5 million bags for 2025/26, marking the fifth consecutive year of deficits. This view is supported by tangible data, including ICE-monitored arabica inventories falling to a 14.5-month low and below-average rainfall (31% of historical average) in Brazil's key Minas Gerais growing region.

Key Decisions for Investors

• Given the diverging fundamentals between arabica and robusta, investors could consider spread trades that are long arabica and short robusta to capitalize on tightening arabica inventories versus the oversupply in robusta.
• The record net-short positioning in robusta futures presents a significant short-squeeze risk; traders with short exposure should monitor for any bullish catalyst and employ disciplined risk management.
• The unresolved U.S. tariff on Brazilian coffee is a critical binary event, and positions should be managed cautiously until there is clarity, as implementation would be a major bearish catalyst.
• Due to the starkly conflicting long-term supply forecasts from the USDA and Volcafe, it is prudent to weigh the near-term physical market tightness in arabica against the broader bearish sentiment before establishing large directional positions.
