US Tariffs on Brazil Boost Arabica Coffee Prices

Coffee prices settled mixed, with September arabica (KCU25) rising 1.32% to a one-week high, while September robusta (RMU25) fell 4.32% to a two-week low. Arabica gained on concerns over potential supply disruptions from Brazil due to proposed U.S. tariffs and slower harvest progress compared to last year. Robusta, conversely, declined amidst signs of increased supply from Vietnam, with Jan-Jun 2025 exports up 4.1% year-over-year. While the USDA forecasts record global coffee production for 2025/26, primarily driven by robusta, Volcafe projects a widening arabica deficit for the fifth consecutive year.

Analysis

The coffee market is exhibiting a significant divergence between arabica and robusta futures, driven by conflicting regional supply signals. Arabica coffee (KCU25) reached a one-week high, gaining 1.32%, primarily due to geopolitical risk after the US proposed a 50% tariff on Brazilian goods, creating uncertainty for supplies from the world's largest arabica producer. This is compounded by a slower-than-average harvest in Brazil, with Cooxupe reporting 40% completion versus 52% at the same time last year, and a sharp 36% year-over-year decline in Brazil's May green coffee exports. Conversely, robusta coffee (RMU25) fell 4.32% to a two-week low, pressured by signs of increased supply from Vietnam, where Jan-Jun 2025 exports rose 4.1% year-over-year. The broader fundamental picture is mixed; the USDA's Foreign Agricultural Service forecasts a record global coffee production for 2025/26, up 2.5%, largely driven by a 7.9% increase in robusta output. However, this bearish global outlook is contrasted by Volcafe's projection of a widening arabica deficit for a fifth consecutive year, indicating underlying tightness in the high-quality bean market. While ICE-monitored robusta inventories have recently declined, arabica stockpiles remain near a five-month high, potentially capping upside price movements.

Key Decisions for Investors

• Consider a spread trade, long arabica and short robusta, to capitalize on the divergent supply fundamentals stemming from potential US tariffs on Brazil and increased exports from Vietnam.
• Investors with long arabica positions should monitor the elevated ICE inventory levels, which are near a five-month high and could act as a significant headwind against a sustained price rally.
• Closely track developments on the proposed US tariffs on Brazil and the pace of the Brazilian harvest, as these are the primary short-term catalysts for arabica price volatility.
• Reconcile the conflicting long-term forecasts from the USDA, which projects a global supply surplus, and Volcafe, which projects a deepening arabica deficit, as the market's conviction towards either view will dictate the medium-term price trend.
