Arabica coffee futures fell on Monday, with December delivery settling lower after consolidating above a recent 3-week trough. December arabica coffee ended down 1.35 cents (down 0.43%) and closed at KCZ26, while November ICE robusta did not trade because UK markets were closed for a holiday.
Key takeaways
- Price move: December arabica coffee fell 0.43% on Monday after holding above last Thursday’s 3-week low.
- Catalyst: Traders weighed improving signals on Brazil harvest progress against ongoing supply-risk factors, including Colombia’s earthquake impact and record-low arabica inventories.
- Implication: The market is likely to remain sensitive to weekly inventory updates and further weather developments tied to El Niño.
- Robusta watch: Robusta has separate bearish and bullish drivers, including inventory trends and Vietnam’s export surge.
What drove the move
Arabica prices eased as investors took stock after last week’s pullback. Earlier, the market sold off toward last Thursday’s 3-week low, reflecting concerns that Brazil’s coffee harvest could add supply.
Harvest progress in Brazil has been mixed but generally points to continued movement in crop availability. Cooxupe reported that 87.5% of the 2026/27 harvest was complete as of Aug. 21, up 6 percentage points from the prior week but slightly behind a year earlier. Safras & Mercado reported that the 2026/27 crop was 97% finished as of Aug. 26, compared with 100% at the same point last year and a 5-year average of 98%. For arabica specifically, Brazil’s harvest was reported at 96% complete, versus 99% a year ago.
Despite these supply-linked signals, arabica remains supported by inventory conditions. Data cited from ICE showed arabica inventories fell to a 27-year low of 223,976 bags last Friday. That helps counterbalance near-term harvest worries by keeping the market’s immediate supply cushion tight.
Colombia’s earthquake earlier this month also continues to underpin sentiment for arabica. The 7.4 magnitude quake hit major coffee-growing areas including Caldas and Risaralda, which account for roughly a quarter of Colombia’s production. Export activity has partially resumed through Buenaventura, which handles most Colombian coffee exports, but traffic has remained intermittent and limited, according to a Bloomberg report citing Asoexport’s head.
Weather expectations added another layer to the trading backdrop. A potential El Niño pattern has been viewed as a risk to Brazil’s next crop cycle, with Commercial saying El Niño could delay rains in Brazil during September and October—when tree flowering typically occurs. The US Climate Prediction Center previously said the emerging El Niño is likely to be among the strongest in more than 75 years, raising the possibility of disruptions later in the year across parts of Asia and South America.
At the same time, there are countervailing bearish elements. Somar Meteorologia reported that Minas Gerais—Brazil’s main arabica-growing region—received 8.9 mm of rain in the week ended Aug. 30, or 127% of the historical average. Above-normal rainfall can support flowering conditions for the following season, pressuring prices when traders are weighing El Niño risk versus current moisture.
Market reaction: inventory vs. harvest
Monday’s decline in December arabica suggests the market is consolidating rather than breaking sharply higher after last week’s drop. Investors appear to be balancing two competing forces: Brazil’s harvest trajectory, which may keep supply expectations anchored higher, and the tight state of ICE arabica stocks, which can limit downside if consumption demand persists or supply shocks emerge.
For robusta, the inventory picture is currently less supportive. ICE robusta inventories rose to a 9-month high of 4,943 lots last Tuesday, which can weigh on prices by signaling a roomier near-term supply position. While robusta did not trade on Monday due to the holiday, the underlying inventory trend remains a key reference point for when trading resumes.
What to watch next for coffee traders
Next, market participants will likely focus on confirmation of Brazil’s crop pace and storage logistics, plus any updates that clarify the longer-term impact of Colombia’s earthquake on export flow. Weather forecasts—especially those tied to El Niño development and regional rainfall patterns—remain a central driver for both arabica and robusta.
Also in focus are broader fundamentals reflected in USDA outlooks. The USDA’s latest biannual forecast was described as bearish for coffee prices, projecting higher global output and rising world ending stocks, with improved growing conditions in Brazil offsetting some production risks.
