Coffee futures surged on Monday, extending a sharp rally across both benchmark arabica and robusta contracts. December arabica coffee closed up 19.00 cents per pound (+5.89%), reaching a 7.5-month high, while September ICE robusta coffee finished higher by 192 points (+5.34%), posting a 1.5-week high as traders focused on tight near-term supply signals.
Key takeaways
- Price move: December arabica coffee rose 19.00 (+5.89%) and September robusta coffee gained 192 (+5.34%).
- Catalyst: Expectations for tighter supply from Brazil’s slower harvest pace, along with falling arabica inventories, outweighed bearish inventory and production forecasts.
- Arabica vs. robusta: Inventories fell for arabica but rose for robusta, helping explain the different underlying price drivers across grades.
- Implication: Weather and crop progression in Brazil and Colombia remain central to the market, even as USDA outlooks point to higher global output in the coming season.
What drove the move
Brazil’s harvest progress was a core factor behind Monday’s jump in coffee prices. According to reporting cited in the market coverage, Cooxupe said 81.1% of Brazil’s harvest was complete as of Aug. 14, up 7 percentage points from the prior week but slightly behind the 86.1% pace from a year earlier. Safras & Mercado also reported that the 2026/27 Brazil coffee harvest reached 90% completion as of Aug. 12, compared with 97% last year and a 5-year average of 94%. For arabica specifically, Brazil’s arabica harvest was noted at 86% completion versus 95% a year earlier.
Those delays matter because they can tighten supplies during a period when roasters rely on steady availability. In addition, the market drew support from inventory dynamics at ICE. Data cited in the coverage showed ICE arabica inventories fell to a 2.75-year low of 226,242 bags on Monday, a bullish signal for near-term availability. By contrast, ICE robusta inventories increased to an 8.75-month high of 4,831 lots, which typically weighs on robusta prices by signaling more stock on hand.
Colombia-related disruption also provided a further lift. The coffee market received support after an earlier-month earthquake in Colombia—a key arabica origin—hit production regions including Caldas and Risaralda, areas collectively accounting for about a quarter of Colombia’s output. While exporters reported that the quake did not cause significant damage to coffee processing and milling facilities, the event still heightened attention on export continuity and regional supply flow.
Market reaction and grade-specific signals
The rally’s split character—strong gains in both grades, but with clearly different underlying inventory trends—helped investors frame the move. Falling inventories are generally supportive for arabica, while rising inventories tend to be a headwind for robusta. Consistent with that, the coverage highlighted that arabica inventory declines coincided with robusta inventory builds.
On the export front, the market also looked to Colombia’s ability to ship. According to a Bloomberg report cited in the coverage, Colombia has partially resumed coffee exports through the Buenaventura port, which handles most Colombian shipments. However, the report also said port traffic remains intermittent and limited, leaving uncertainty around the near-term pace of export deliveries even as the country works through post-quake disruptions.
Weather risk further contributed to trader positioning. The coverage pointed to concerns that an El Niño pattern could disrupt Brazil’s crop timing next year, particularly by delaying rains during the September-to-October window when tree flowering typically occurs. A report cited in the coverage referenced the US Climate Prediction Center saying El Niño conditions are likely to be among the strongest in more than 75 years, raising the possibility of later-season fluctuations in temperature and rainfall that could affect coffee production across parts of Asia and South America.
Not all weather signals were uniformly bullish, though. The same coverage noted that below-average rainfall in Brazil could speed up the harvest pace—bearish for prices if it leads to quicker arrivals of beans into the market. Somar Meteorologia data cited in the report estimated that 0.6 mm of rain, or 11% of the historical average, fell in the week ended Aug. 16 in Minas Gerais, Brazil’s main arabica-producing region.
What countered the rally
Despite Monday’s strong price action, several factors cited in the coverage pointed to supply improvement risks later. For robusta, Vietnam export strength was presented as a bearish pressure. According to Vietnam’s National Statistics Office data cited in the coverage, Vietnam’s 2026 coffee exports (Jan–Jul) rose 21.1% year over year to 1.31 million metric tons, and 2025 exports increased 17.5% year over year to 1.58 million metric tons. The report also cited expectations for Vietnam’s 2025/26 production to increase 6% year over year to a four-year high of 1.76 million metric tons (29.4 million bags).
Broader production expectations also tempered the bullish narrative. The coverage referenced the latest USDA biannual forecast from July 22, which projected global coffee output in the 2026–27 season rising 6.0% to a record 189.7 million bags, driven mainly by improved growing conditions in Brazil. It also cited USDA expectations that global arabica production would increase 12% year over year, while robusta production would decline 0.7% year over year. In addition, USDA was cited as projecting world ending stocks rising 1.9 million bags to 26.3 million bags. Earlier USDA Foreign Agricultural Service estimates referenced in the coverage also pointed to a record 2026/27 Brazil crop of 71.9 million bags, up 14% year over year.
Bigger picture: supply tightness vs. forward output
Monday’s rally underscored the market’s near-term focus: tighter arabica inventory readings and slower harvest progress in Brazil outweighed longer-horizon expectations for higher global production. Traders will likely continue to weigh headline developments—harvest pace, export flows after disruptions, and evolving weather models—against USDA-style outlooks that suggest stock buildups may eventually limit upside.
What to watch next: Investors are likely to monitor Brazil harvest pace updates, inventory trends at ICE for both arabica and robusta, and weather forecasts tied to El Niño conditions. Additional market catalysts to watch include further USDA adjustments and follow-on reporting on harvest completion rates and export throughput from major producing origins.
