Coffee futures fell sharply on Monday as the Brazilian real weakened, encouraging producers to sell and triggering long liquidation in ICE coffee contracts. September Arabica coffee for ICE October 2026 delivery (KCU26) dropped 11.70 cents, or 3.45%, while September ICE robusta coffee (RMU26) fell 88 points, or 2.27%.
The currency move drove part of the day’s downside: the real slid to a 2.5-week low versus the U.S. dollar, making it more attractive for Brazil-based exporters to lock in foreign-currency revenues. With prices already sensitive to supply expectations, the combination of a weaker currency and position trimming pushed both Arabica and robusta lower.
Key takeaways
- Price move: September Arabica futures (KCU26) fell 3.45% and September robusta (RMU26) declined 2.27%.
- Catalyst: The Brazilian real weakened to a 2.5-week low against the dollar, prompting long liquidation in coffee futures.
- Arabica vs. robusta: Arabica inventories are near a multi-year low, but robusta inventories remain elevated, pressuring prices in robusta.
- Supply signals matter: Recent USDA expectations for a larger global crop have weighed on prices, even as weather and harvest pace raised short-term concerns.
What drove the move
According to trading and market commentary reflected in the report, the dominant near-term factor was FX-linked liquidation. As the Brazilian real (tracked via the U.S. dollar versus the Brazilian real) dropped to a 2.5-week low, the economic incentive for Brazilian coffee producers to export increased, which can translate into heavier available supply reaching the market.
That selling pressure arrived after a recent rebound. On Tuesday, coffee prices had rallied to two-week highs amid concerns that heavy rain in Brazil could disrupt the country’s coffee harvest and tighten global supplies. The same report cited Somar Meteorologia data showing 32.4 mm of rain—or 2700% of the historical average—in the week ended July 26 in Minas Gerais, Brazil’s largest coffee-growing state.
Still, investors were balancing those weather risks against broader production expectations. Earlier, coffee prices slid to three-week lows after the USDA forecast that global coffee output in the 2026–27 season would rise by 6.0% (to 10.8 million bags) to a record 189.7 million bags, driven largely by improved growing conditions in Brazil.
Market reaction across Arabica and robusta
The inventory picture helped explain why the market’s direction split between the two major coffee benchmarks.
Robusta: Rising robusta inventories have been a headwind. ICE robusta inventories climbed to a 4.25-month high of 4,254 lots last Wednesday, though they were noted to be modestly lower at 4,136 lots on the current day.
Arabica: Arabica faced less inventory pressure. The report said ICE arabica coffee inventories fell to a 2.5-year low of 289,759 bags on Tuesday, a factor that has supported arabica even as the market digested larger crop expectations at the global level.
Earlier in the month, weather risk and harvest pace had also supported prices. The report cited progress behind last year’s pace among Brazilian producers and co-ops, including Cooxupe harvest completion at 58.3% as of July 24 versus 67% a year earlier. Safras & Mercado similarly reported that Brazil’s 2026/27 harvest was 64% complete as of July 15, behind the 77% level at the same point last year and the five-year average of 70%.
What to watch next
Investors are likely to focus on whether near-term weather disruptions translate into sustained tighter supply, or whether improving agronomic conditions and forecasted production growth offset those risks.
Key items to monitor include ongoing updates on Brazil’s harvest pace, further inventory readings from ICE, and the evolution of expectations tied to El Niño. The report referenced concerns that El Niño could delay rains during Brazil’s September–October flowering window, potentially affecting the 2026/27 crop. It also pointed to U.S. Climate Prediction Center commentary that El Niño conditions may be among the strongest in more than 75 years, with potential downstream weather volatility across major coffee-producing regions.
On the demand and trade side—especially relevant for robusta—market participants will likely track Vietnam export trends and production outlook, given the report’s bearish notes on rising Vietnam exports and a projected increase in production.
