Coffee futures settled mixed on Tuesday, with September arabica coffee gaining sharply to close higher, while July ICE robusta eased. Prices tracked shifting supply expectations tied to Brazil weather disruptions for arabica, alongside relief on shipping and steady robusta supply signals.
Key takeaways
- Arabica surged: September arabica coffee for the KCU26 contract closed up +8.95 (about +3.35%) after rallying to a 6-week high.
- Robusta slipped: July ICE robusta coffee for the RMN26 contract closed down -9 (about -0.25%), falling to a 1-week low.
- Catalyst for arabica: Renewed rains in Brazil and a cold front supported arabica by delaying parts of the harvest and raising quality-crop concerns.
- Catalyst for robusta: The reopening of the Strait of Hormuz was viewed as easing shipping-related cost pressures, weighing on robusta.
- Implication for traders: Weather risk in Brazil remains the near-term driver for arabica, while logistics relief and inventory swings are keeping robusta price gains capped.
What drove arabica higher
September arabica closed at its strongest level in roughly six weeks as market participants focused on Brazil’s near-term production calendar. Renewed rainfall in Brazil is delaying the country’s coffee harvest, which tends to tighten short-term supply availability and can increase the probability of quality issues.
According to meteorologist Climatempo, a new cold front supporting rains over southern Brazil is affecting field activities and could influence crop quality. That combination—slower harvest progress and potential quality deterioration—was a key reason arabica attracted fresh buying into Tuesday’s close.
Why robusta weakened
Robusta fell to a one-week low as the market responded to improving logistics conditions. The reopening of the Strait of Hormuz was cited as reducing supply disruptions, a development that traders generally treat as bearish for coffee prices because it can lower shipping rates and associated costs.
The easing logistics outlook was linked to reduced pressure across areas that raise costs for importers and roasters, including shipping, insurance, fertilizer, and fuel. While coffee-specific demand has not been cited as the driver, the market reaction suggests traders weighed macro-style cost relief more heavily for robusta than for arabica on Tuesday.
Inventories and broader weather risk
Inventory trends provided additional nuance. ICE coffee inventories have edged lower over the past three months, a pattern that typically supports prices. On Tuesday, ICE arabica inventories fell to a 2.25-year low of 392,901 bags, reinforcing the tighter supply signal for arabica.
Robusta inventory dynamics were more mixed. ICE robusta inventories fell to a 2-year low of 3,631 lots on May 15 but later increased to a 2.25-month high of 4,032 lots last Thursday. That volatility in robusta stocks helped limit the impact of any supportive inventory trend.
Looking ahead, El Niño concerns continue to underpin the forward curve. Coffee trader Commercial said the El Niño weather pattern could delay rains in Brazil in September and October, which coincide with normal tree flowering—raising the risk of damage to Brazil’s 2026/27 crop.
NOAA estimated a 67% probability of a “Super El Niño” this year, which it described as potentially the strongest on record. Separately, the Japan Meteorological Agency confirmed an El Niño pattern formed across the equatorial Pacific on June 10, setting the stage for later-season weather variability that could affect coffee production in parts of Asia and South America.
Context from recent fundamentals
Arabica’s rebound came after earlier weakness tied to expectations of a larger Brazilian crop. On June 9, arabica fell to a 19-month nearest-futures low, and robusta slid to a 2-month low, following forecasts pointing to a bumper harvest in Brazil this year.
According to prior USDA Foreign Agricultural Service (FAS) reporting cited in the market recap, FAS forecast a record 2026/27 Brazil coffee crop of 71.9 million bags, up 14% year over year. Rabobank also raised its estimate for the 2026/27 global arabica surplus to 9.5 million bags from 7.0 million bags, while Cecafe reported Brazil’s May green coffee exports rose +4.2% year over year to 2.73 million bags.
For robusta, supply signals from Vietnam have been a recurring headwind. Vietnam’s National Statistics Office reported that Vietnam’s 2026 coffee exports (Jan–May) rose +7.9% year over year to 922,000 metric tons, and Vietnam’s 2025 exports increased +17.5% year over year to 1.58 million metric tons. The same reporting indicated 2025/26 production is projected to climb 6% year over year to a four-year high of 1.76 million metric tons (or 29.4 million bags).
Broader export data has also been mixed. The International Coffee Organization (ICO), in an update referenced in Tuesday’s recap, reported that global coffee exports for the current marketing year (Oct–Sep) fell -0.3% year over year to 138.658 million bags.
In the USDA FAS bi-annual report cited in the recap, world coffee production for 2025/26 was projected to rise +2.0% year over year to a record 178.848 million bags, with arabica production decreasing -4.7% to 95.515 million bags and robusta increasing +10.9% to 83.333 million bags. The report also projected 2025/26 ending stocks to fall -5.4% to 20.148 million bags.
What to watch next
Traders are likely to keep monitoring Brazil’s rainfall trajectory and harvest progress, given its direct linkage to near-term arabica supply and potential quality outcomes. On the robusta side, attention will likely remain on shipping and logistics developments, alongside ongoing inventory data. Weather forecasts tied to El Niño evolution will be central to the next moves in both contracts, as markets look for clarity on whether rainfall delays or dryness risk will dominate the coming months.
