Coffee futures rebounded sharply on Monday, with September Arabica settling higher and September ICE Robusta also gaining, as renewed concerns about Brazilian weather threatened tighter global supplies. The move came after a prior selloff tied to expectations of rising output, underscoring how quickly sentiment can swing between forecasts and near-term crop conditions.
Somar Meteorologia reported unusually heavy rainfall in Brazil’s key coffee-growing areas, while the pace of harvest progress remained behind last year. The market’s pricing of tighter Arabica supplies contrasted with pressure on Robusta from higher inventories and stronger export flows from Vietnam.
Key takeaways
- Arabica: September Arabica coffee futures closed up +10.75 (about +3.43%), supported by weather-driven supply concerns in Brazil.
- Robusta: September ICE Robusta coffee futures finished up +42 (about +1.12%), but gains were smaller as inventories remain elevated.
- Catalyst: Heavy rain in Minas Gerais and evidence of slower harvest progress added risk to Brazil’s crop timing and quality.
- Implication: Market direction is being shaped by competing signals—Brazil weather and Arabica inventory tightness versus Robusta inventory build and Vietnam exports.
What drove the move
Monday’s rally was anchored in Brazil weather and harvest pacing. According to Somar Meteorologia, 32.4 mm of rain—described as 2700% of the historical average—fell in the week ended July 26 in Minas Gerais, Brazil’s largest coffee-growing state. Such conditions raise the risk of disruptions during key stages of crop development and can translate into supply uncertainty for future harvests.
Beyond the weather, harvest progress remained slower than the prior year. Data cited from the Cooxupe coffee cooperative showed its members’ harvest was 47.3% complete as of July 17, versus 59% at the same point last year. A separate report referenced Safras & Mercado indicating Brazil’s 2026/27 harvest was 64% complete as of July 15, behind last year’s 77% and the five-year average of 70%.
How the prior selloff matters
Sentiment had turned negative into Friday’s trading, when coffee prices dropped to three-week lows following the USDA’s forecast for global production growth in the 2026–27 season. The USDA expected global coffee output to rise 6.0% to a record 189.7 million bags, driven largely by improved growing conditions in Brazil. The same outlook projected arabica production rising 12% year over year, while robusta production was expected to fall 0.7%.
The USDA also projected world ending stocks to climb by 1.9 million bags to 26.3 million bags. These estimates had weighed on prices—especially robusta—by signaling a path toward higher inventories.
Further context from USDA material cited in the report pointed to a record 2026/27 Brazil coffee crop of 71.9 million bags, up 14% year over year, based on a Foreign Agricultural Service forecast published on June 3.
Arabica vs. robusta: inventories and supply signals
Although both contracts rose on Monday, the drivers diverged across the two markets.
Robusta: The report said rising inventories continued to weigh on robusta, with ICE robusta inventories reaching a four-and-a-quarter-month high of 4,254 lots last Wednesday. Inventories eased slightly to 4,228 lots on Monday, but the overall inventory level remained a headwind for price strength.
Arabica: A bullish factor for arabica was tighter stocks. ICE arabica coffee inventories fell to a 2.5-year low of 292,810 bags on Monday, helping support prices even after the USDA’s broader output outlook pressured the market earlier in the week.
Weather risk and competing bearish flows
In addition to near-term rainfall, El Niño-related concerns provided an additional layer of support for coffee prices. Commercial cited the possibility that the El Niño pattern could delay rains in Brazil during September and October—months when tree flowering typically occurs—potentially affecting the 2026/27 crop.
According to the U.S. Climate Prediction Center, the El Niño conditions developing across the equatorial Pacific last month are expected to become one of the strongest in more than 75 years, raising the likelihood of later-year disruptions such as floods, droughts, and temperature swings that could affect production across parts of Asia and South America.
On the bearish side for robusta, the report highlighted strong export momentum from Vietnam, the world’s largest robusta producer. Vietnam’s National Statistics Office reported 2026 coffee exports (January–June) rose 7.3% year over year to 1.05 million metric tons, and 2025 exports jumped 17.5% to 1.58 million metric tons. The same reporting framework suggested 2025/26 Vietnam production is projected to rise 6% year over year to 1.76 million metric tons (about 29.4 million bags), reinforcing supply availability for robusta markets.
What to watch next
Traders will likely focus on whether rainfall in Brazil persists and how quickly harvest conditions change relative to the slower pace cited for Minas Gerais and nationwide. Ahead, investors will also be watching weather follow-through tied to El Niño and upcoming assessments of crop development, along with any additional updates to inventory levels at ICE that could further separate the outlook for arabica versus robusta.
