Coffee Prices Decline on Above-Average Rainfall in Brazil

Coffee prices, including arabica and robusta, declined on Monday, primarily due to above-average rainfall in Brazil's key Minas Gerais region, which is expected to improve crop conditions during the critical flowering period. This recent downturn contrasts with earlier bullish factors such as 50% US tariffs on Brazilian imports causing ICE arabica inventories to hit a 1.5-year low and reduced Brazilian exports, alongside La Niña concerns. However, a strong robusta crop in Vietnam and advanced Brazilian harvest progress provide bearish counterpoints, while long-term outlooks remain mixed, with USDA forecasting increased global production but Volcafe projecting a widening 2025/26 global arabica deficit.

Analysis

Arabica (KCZ25) and robusta (RMX25) coffee futures declined -1.55% and -0.36% respectively, primarily due to immediate bearish weather news from Brazil. The key arabica-growing region of Minas Gerais received 104% of its historical average rainfall, improving prospects for the critical flowering period and boosting yield expectations. This short-term supply optimism is compounded by reports of a bumper 2025/26 robusta crop from Vietnam, projected to be up +6% year-over-year, and harvest pressure in Brazil, where the Cooxupe co-op's harvest is 98.9% complete. However, these factors are juxtaposed with significant bullish undercurrents. US tariffs of 50% on Brazilian imports are constricting US supply and have contributed to a sharp drawdown in inventories, with ICE-monitored arabica stocks falling to a 1.5-year low. This is corroborated by several reports of falling Brazilian exports, with Cecafe noting a -28% year-over-year decline in July green coffee exports. The market faces considerable uncertainty in its forward outlook, with the USDA forecasting record global production for 2025/26, while private forecaster Volcafe projects a widening arabica deficit of -8.5 million bags for the same period. Adding a longer-term bullish risk is the 71% probability of a La Niña event, which could introduce dry conditions for Brazil's 2026/27 crop.

Key Decisions for Investors

• Investors should weigh the immediate bearish pressure from favorable Brazilian weather and a strong Vietnamese robusta crop against the medium-term bullish impact of critically low ICE inventories and US tariff-driven supply tightness.
• Monitor incoming Brazilian export data and weekly ICE inventory reports closely to validate which of the conflicting 2025/26 supply forecasts from the USDA and Volcafe is materializing.
• Consider the potential for a widening arabica-robusta price spread, as forecasts suggest a divergence with falling arabica production (-1.7% per USDA) but rising robusta supply (+7.9% per USDA).
• Recognize that US-Brazil trade policy is a key non-fundamental risk; any change to the 50% tariff could rapidly alter US supply dynamics and futures pricing.
