Arabica coffee futures ended Friday higher while robusta futures fell, extending a mixed tone across the benchmark complex. September arabica coffee closed up 5.00, or 1.50%, and September ICE robusta coffee finished down 45, or 1.23%, as traders weighed crop progress in Brazil against supply disruption risk in Colombia and shifting warehouse stocks.
Key takeaways
- Price move: September arabica rose 1.50% while September robusta fell 1.23% on Friday.
- Catalyst: Markets reacted to Brazil harvest pace updates and Colombia export disruption concerns, alongside inventory trends in ICE warehouses.
- Arabica implication: Lower ICE arabica inventories supported prices.
- Robusta implication: Rising ICE robusta inventories weighed on the market.
- Forward risk: Weather uncertainties tied to El Niño and USDA production forecasts kept traders attentive to the next crop cycle.
What drove the move
Support for arabica came from indicators pointing to a slower-than-normal pace of Brazil’s ongoing harvest. Safras & Mercado said Brazil’s 2026/27 coffee harvest was 90% complete as of August 12, versus 97% a year earlier, and below the 5-year average of 94%. The arabica portion of the harvest was 86% complete, behind last year’s 95%.
For robusta, the day’s direction reflected a lack of similar inventory-tightness signals and attention to other supply dynamics. The report also referenced progress among members of Cooxupe, where harvest completion was 74.6% as of August 7, behind 80.4% in the prior-year period, according to a Wednesday note. Those figures contributed to uncertainty over near-term supply timing—though the market’s inventory data ultimately played a larger role.
Separately, traders assessed disruptions to Colombian coffee exports after a devastating earthquake struck on Monday. Reports cited a 7.4 magnitude quake affecting Caldas and Risaralda, provinces that contribute about a quarter of Colombia’s production. According to a Bloomberg report quoting Asoexport, Colombia has partially resumed exports through the Buenaventura port—handling most Colombian coffee shipments—but traffic remains intermittent and limited. Exporters told the publication that there was no significant damage to coffee processing and milling facilities.
Inventory trends split arabica and robusta
ICE inventory data provided the most concrete divergence between the two contracts. Falling stocks were described as bullish for arabica coffee, with ICE arabica inventories dropping to a 2.75-year low of 231,445 bags on Friday. By contrast, rising inventories were bearish for robusta: ICE robusta stocks climbed to a 5-month high of 4,537 lots on Friday.
That imbalance helped explain why arabica finished higher even as both contracts faced competing supply and weather headlines. When inventory signals lean tighter for one variety than the other, traders typically reprice near-term availability accordingly.
Weather, Vietnam exports, and USDA forecasts in focus
Beyond harvest progress, weather inputs offered mixed implications for Brazil. Somar Meteorologia reported that 5.8 mm of rain, equivalent to 92% of the historical average, fell in the week ended August 9 in Minas Gerais, Brazil’s main arabica-growing region. Below-normal rainfall can speed up harvest completion, which is generally bearish if it implies more coffee reaching the market sooner.
At the same time, the risk of an El Niño pattern supported the complex by raising concerns about the next crop cycle. A trader, Commercial, said El Niño could delay rains in Brazil during September and October—months when tree flowering normally occurs—potentially affecting the 2026/27 crop. The US Climate Prediction Center said the El Niño developing across the equatorial Pacific is likely to be among the strongest in more than 75 years, which can increase the probability of uneven rainfall and temperature swings that affect production across parts of Asia and South America.
For robusta, trading attention also turned to Vietnam, the world’s largest robusta producer. Data from Vietnam’s National Statistics Office showed Vietnam’s 2026 coffee exports (Jan–Jul) rose 21.1% year over year to 1.31 million metric tons, while 2025 exports increased 17.5% year over year to 1.58 million metric tons. The same reporting indicated Vietnam’s 2025/26 production is projected to rise 6% year over year to 1.76 million metric tons (29.4 million bags), a supportive backdrop for robusta supply expectations.
US supply forecasts also weighed on pricing expectations. The USDA’s latest biannual forecast projected global coffee output in the 2026–27 season rising 6.0% (10.8 million bags) to a record 189.7 million bags, driven primarily by improved growing conditions in Brazil. The USDA expected arabica production to rise 12% year over year, while robusta production was expected to fall 0.7% year over year. World ending stocks were projected to increase by 1.9 million bags to 26.3 million bags. The USDA’s Foreign Agricultural Service forecast, dated June 3, projected a record 2026/27 Brazil coffee crop of 71.9 million bags, up 14% year over year.
Market reaction and what investors are watching next
The split close on Friday reflected how traders prioritized different signals for each variety: tightening arabica inventories and harvest timing supported arabica, while robusta’s rising warehouse stocks and stronger Vietnam export/output backdrop kept pressure on robusta prices. Colombia’s partial export resumption after the earthquake added uncertainty, but the market appeared to treat processing damage as limited—leaving inventory levels and production forecasts as the main drivers.
Going forward, participants are likely to monitor Brazil rainfall and El Niño development into September and October flowering, the consistency of Colombian port flows through Buenaventura, and any updates to inventory levels in ICE warehouses. Additional attention will likely follow USDA-related guidance and the next set of crop and export reports that clarify how quickly supplies reach market.
