Coffee futures fell on Friday as the latest U.S. Department of Agriculture outlook pointed to a larger global crop and higher inventories, weighing most heavily on robusta. September arabica coffee futures dropped 7.05 cents (down 2.23%), while September ICE robusta coffee fell 86 dollars (down 2.27%).
The selloff followed a USDA forecast released late Wednesday projecting that the 2026-27 coffee season will see global output rise 6.0% to a record 189.7 million bags, driven largely by improved growing conditions in Brazil. The USDA also projected arabica production to increase 12% year over year, even as robusta output is expected to decline 0.7% year over year.
Key takeaways
- Price move: September arabica coffee fell 2.23%, while September robusta declined 2.27%.
- Catalyst: A USDA forecast called for record global production and higher ending inventories for 2026-27.
- Implication for arabica: Stocks data remain tight, supporting prices even as the broader market weakened.
- Implication for robusta: Rising robusta inventories and export momentum from Vietnam add pressure.
- Weather risk remains: Concerns about El Niño could affect Brazil’s next crop, potentially countering supply headwinds later.
What drove the move
According to the USDA forecast, the 2026-27 season’s global ending stocks are expected to rise by 1.9 million bags to 26.3 million bags, after an outlook that emphasized production strength. The report pinned the bulk of the year-over-year improvement on Brazil’s improved growing conditions, setting a more supply-forward tone for both arabica and overall market expectations.
Within the USDA framework, arabica output was forecast to increase, while robusta production was expected to decline slightly. That mix matters because the market’s immediate price action reflected not just near-term demand expectations, but also inventory dynamics—where robusta is currently under greater pressure.
Market reaction and inventory signals
Inventories provided a key split between the two contracts. Data from ICE showed robusta inventories climbed to a 4-month high of 4,254 lots on Wednesday, up from the 2.25-year low of 3,631 lots recorded on May 15. That buildup tends to cap rallies in robusta by increasing the near-term availability of beans.
In contrast, ICE arabica inventories fell to a 2.25-year low of 320,615 bags on Wednesday, a tighter supply signal that can limit downside. While arabica still traded lower on the USDA-driven bearish supply narrative, the inventory backdrop appears more supportive than it is for robusta.
Brazil harvest outlook: mixed near-term factors
Coffee prices also faced headwinds tied to near-term weather. The outlook includes concerns about drier conditions in Brazil’s coffee-growing areas, which could accelerate harvesting in the coming weeks and increase supply flow to the market.
However, reports cited by the market suggest harvest progress is still behind typical seasonal pace, providing some support. Data discussed from Cooxupe indicated harvest completion of 47.3% as of July 17, slower than the year-earlier 59%. Safras & Mercado also reported that Brazil’s 2026-27 coffee harvest was 64% complete as of July 15, compared with 77% at the same point last year and a five-year average of 70%.
Taken together, the harvest indicators point to faster weather-driven picking potential, but still-constrained near-term volumes relative to last year and the average—factors that help explain why arabica’s decline, while significant, appeared less driven by inventories than robusta.
El Niño risk and export pressures
Beyond the immediate inventory and crop-size narrative, weather risk remains a key swing factor. Traders highlighted concerns that El Niño could disrupt Brazil’s next crop cycle. One market view cited by Commercial suggested the El Niño pattern may delay rains in Brazil during September and October, when tree flowering normally occurs. That timing could affect the 2026-27 coffee crop.
According to the U.S. Climate Prediction Center, the El Niño developing across the equatorial Pacific is likely to be among the strongest in more than 75 years, raising the possibility of floods, droughts, and temperature swings later this year that could affect coffee production across Asia and South America.
Still, near-term rainfall data cited by Somar Meteorologia showed limited rain in Minas Gerais—Brazil’s largest coffee state—with 0.2 mm falling in the week ended July 19, or about 20% of the historical average. For markets, that type of signal can increase short-term uncertainty, even as supply expectations dominate the day-to-day price tape.
For robusta specifically, additional bearish pressure comes from Vietnam’s export momentum. Vietnam’s National Statistics Office reported that 2026 coffee exports in the January-June period rose 7.3% year over year to 1.05 million metric tons. It also said 2025 coffee exports jumped 17.5% year over year to 1.58 million metric tons. On the production side, Vietnam’s 2025-26 output is projected to rise 6% year over year to 1.76 million metric tons (29.4 million bags).
Bigger picture: what investors will track next
With USDA’s larger crop and inventory projection setting the tone, traders are likely to focus on whether weather risks translate into measurable supply disruptions during key development windows. In the near term, Brazil harvest pace and local rainfall patterns could influence the timing of arrivals, while the pace of robusta exports and ongoing ICE inventory trends will remain central for the spread between arabica tightness and robusta oversupply signals.
Investors will also watch upcoming USDA updates and weather forecasts tied to El Niño, alongside any additional industry reporting on Brazil’s harvest progression and stock levels—factors that can quickly shift expectations for both the 2026-27 season and the price path for the next contract months.
