December arabica coffee (KCZ26) closed down -4.30 (-1.45%) on Tuesday, and November ICE robusta coffee (RMX26) closed up +53 (+1.56%).

Coffee prices settled mixed on Tuesday, with arabica falling to a 2-month low.  Ramped-up coffee exports from Brazil weighed on arabica prices Tuesday after Brazil’s Trade Ministry reported Brazil’s Aug coffee exports rose +44.6% y/y to 206,618 MMT, the most in 8 months.   

Robusta coffee rose Tuesday as forecasts for heavy rains in Vietnam’s Central Highlands, the country’s largest coffee-producing region, may flood farms and damage the country’s coffee crop. 

Last Thursday, robusta fell to a 3-month low on signs of bigger coffee supplies from Vietnam, the world’s largest producer of robusta coffee.  Vietnam’s National Statistics Office reported last Wednesday that Vietnam’s 2026 coffee exports (Jan-Aug) rose by +13.7% y/y to 1.33 MMT. 

Above-normal rainfall in Brazil may benefit flowering for next year’s coffee harvest, a bearish factor for prices.  Somar Meteorologia reported last Monday that 8.9 mm of rain, or 127% of the historical average, fell in the week ended August 30 in Brazil’s Minas Gerais, the country’s main arabica-coffee growing region.

Falling inventories are bullish for arabica coffee prices, as ICE arabica coffee inventories fell to a 27-year low of 218,838 bags on Tuesday.  By contrast, rising inventories are bearish for robusta coffee as ICE robusta inventories climbed to a 9.25-month high of 5,004 lots last Wednesday.

Late last month, arabica coffee rallied to an 8-month high due to the slow pace of Brazil’s coffee harvest. Coffee prices also have support from the devastating earthquake last month in Colombia, the world’s second-largest producer of arabica beans.  Among the areas hit by the 7.4 magnitude quake were the coffee-growing provinces of Caldas and Risaralda, which account for about a quarter of Colombia’s production. 

Concerns that an El Niño weather pattern could hurt Brazil’s coffee crop next year are bullish for prices. Coffee trader Commercial said the El Niño weather pattern may delay rains in Brazil this September and October, when tree flowering normally occurs, hurting Brazil’s 2026/27 coffee crop. On July 8, the US Climate Prediction Center said the El Niño weather pattern that emerged across the equatorial Pacific last month will likely be one of the strongest in more than 75 years. This sets the stage for months of possible floods, droughts, and temperature fluctuations later this year that could hinder coffee production in Asia and South America. 

Soaring coffee exports from Vietnam, the world’s largest robusta producer, are bearish for robusta prices.  Vietnam’s 2025 coffee exports jumped by +17.5% y/y to 1.58 MMT.  Also, Vietnam’s 2025/26 coffee production is projected to climb +6% y/y to a 4-year high of 1.76 MMT (29.4 million bags).

The latest USDA biannual forecast was bearish for coffee prices.  On July 22, the USDA forecast that global coffee output in the 2026-27 season will rise by +6.0% (10.8 million bags) to a record 189.7 million bags, mainly due to improved growing conditions in Brazil.  The USDA expects global arabica production to rise +12% y/y, although robusta production is expected to fall by -0.7% y/y.  World ending stocks are expected to rise +1.9 million bags to 26.3 million bags.  On June 3, the USDA’s Foreign Agricultural Service (FAS) forecast a record 2026/27 Brazil coffee crop of 71.9 million bags, up +14% y/y.
