Reduced Tariff Risks Weigh on Arabica Coffee

Coffee prices settled mixed on Wednesday, with September arabica down amid easing concerns over Brazilian tariffs and advanced harvest progress, alongside recent beneficial rains in Brazil. Conversely, September robusta climbed to a two-week high, supported by dry weather forecasts for top producer Vietnam and a notable increase in fund net-short positions, signaling potential for a short-covering rally. While global coffee production is broadly projected to increase for 2025/26, leading to higher ending stocks, Volcafe forecasts a widening arabica deficit, adding complexity to the supply outlook.

Analysis

The coffee futures market is exhibiting a distinct divergence, with September arabica futures declining while robusta futures reached a two-week high. Arabica's weakness is primarily driven by easing supply concerns from Brazil, the world's largest producer. This stems from a statement by Commerce Secretary Lutnick suggesting Brazilian coffee may be exempt from tariffs, coupled with strong harvest progress; Cooxupe reported its harvest was 67% complete by July 25, while Safras & Mercado noted Brazil's overall harvest was 84% complete, ahead of both last year's 81% and the 5-year average of 77%. Favorable weather, including recent rainfall in Minas Gerais at over 200% of the historical average, further supports a bearish outlook for arabica. In contrast, robusta prices are rallying on supply threats from Vietnam, the top producer, where forecasts indicate persistent dry weather. This is amplified by a significant build-up in speculative short positions, with funds boosting net-short robusta positions to 4,628 contracts, the highest in two years, creating conditions ripe for a short-covering rally. The broader market outlook is clouded by conflicting long-term forecasts: the USDA projects a record global coffee production for 2025/26 at 178.68 million bags, while Volcafe anticipates a widening arabica deficit of -8.5 million bags, marking the fifth consecutive year of deficits.

Key Decisions for Investors

• Consider a spread trade strategy, potentially long robusta futures against short arabica, to capitalize on the opposing fundamental drivers of adverse weather in Vietnam and easing supply pressures from Brazil.
• Investors should closely monitor fund positioning in robusta futures, as the two-year high in net-short positions presents a significant risk of a volatile short-covering rally if weather concerns in Vietnam persist or worsen.
• For arabica-focused positions, the primary catalysts remain the finalization of tariff policies on Brazilian imports and continued monitoring of Brazil's harvest data, as these factors are currently the dominant price drivers.
• Given the starkly contrasting global supply outlooks from the USDA and Volcafe, it is prudent to treat long-term directional bets with caution until further data clarifies whether the market faces a surplus or a deepening deficit.
