Global Coffee Markets Navigate Mixed Signals Between Brazil Weather Support and Vietnam Export Surge

Coffee prices are displaying conflicting momentum today, with arabica and robusta varieties moving in opposite directions. March arabica coffee (KCH26) is climbing +0.60 points (+0.17%), while March ICE robusta coffee (RMH26) has declined -100 points (-2.53%), reflecting divergent supply-demand dynamics across the world’s two dominant coffee varieties. Today’s price action illustrates how regional weather patterns, export volumes, and inventory levels continue to reshape the coffee commodity landscape.

Arabica Coffee Gains Ground Amid Brazil’s Rainfall Deficit and Currency Strength

Brazil’s largest arabica-growing region is experiencing below-average precipitation, providing structural support to arabica coffee prices. According to Somar Meteorologia, Minas Gerais received 47.9 millimeters of rain during the week ended January 2, representing only 67% of its historical average. This rainfall shortfall has implications for the 2025 harvest and reflects the type of weather conditions that can constrain future output.

Adding to this support, Brazil’s currency has appreciated significantly against the dollar. The Brazilian real recently climbed to a 3-week high, a development that typically discourages coffee producers from rushing their export sales. When the real strengthens, Brazilian exporters face reduced dollar-denominated revenues from their coffee sales, creating an incentive to hold supplies in anticipation of more favorable exchange rates. This currency dynamic reinforces the price floor under arabica coffee.

Vietnam’s Coffee Export Momentum Creates Headwinds for Robusta Variety

Vietnam, the world’s dominant robusta coffee producer, is flooding global markets with abundant export volumes. The country’s National Statistics Office reported today that Vietnam’s coffee exports in 2025 jumped +17.5% year-over-year, reaching 1.58 million metric tons. This surge in export activity from Vietnam is easing supply concerns that had previously supported prices, redirecting downward pressure toward robusta coffee in particular.

The expansion of Vietnamese supply stands in sharp contrast to the tightness seen in arabica markets. Vietnam’s role as the leading robusta supplier means that any acceleration in its export activity has outsized influence on the broader coffee complex. The +17.5% year-over-year export growth signals robust production and distribution capabilities, factors that weigh negatively on near-term robusta coffee valuations.

Storage Levels Paint a Complex Picture for Coffee Inventory Dynamics

The Intercontinental Exchange (ICE) inventory data reveals a mixed backdrop. Arabica stockpiles have been volatile in recent weeks, with levels falling to a 1.75-year low of 398,645 bags on November 20 before rebounding to a 2-month high of 456,477 bags by December 24. This inventory compression, while not currently at crisis levels, historically supports prices by signaling constrained availability.

Robusta coffee inventories tell a similar story of tightness followed by slight recovery. ICE robusta stocks hit a 1-year low of 4,012 lots on December 10 but subsequently recovered to a 4-week high of 4,278 lots by December 23 and 24. The overall inventory picture—characterized by recent lows followed by modest rebounds—suggests underlying supply constraints that could provide occasional support to coffee prices, although the direction remains uncertain.

US Coffee Imports and Trade Policy Create Secondary Market Effects

American importers significantly reduced their purchases of Brazilian coffee during the period when US tariffs were in effect. From August through October 2025, when President Trump’s tariffs were actively applied to Brazilian imports, US coffee purchases fell 52% year-over-year to 983,970 bags. Although those tariffs have subsequently been reduced, US coffee inventories remain relatively tight, constraining near-term import demand.

This trade policy dynamic illustrates how geopolitical factors can reshape coffee flows across major trading regions. The rebound in US tariff rates created a temporary but substantial disruption to historical trade patterns, effects that will likely persist as inventory levels gradually normalize.

Global Coffee Production Forecasts Signal Abundant Supplies on the Horizon

Looking ahead to the 2025/26 crop year, the outlook for coffee supplies appears ample. Brazil’s forecasting agency Conab raised its 2025 production estimate by 2.4% to 56.54 million bags in early December, signaling robust crop expectations despite earlier concerns about dryness in certain regions.

The USDA Foreign Agriculture Service (FAS) projected in mid-December that world coffee production will increase +2.0% year-over-year in 2025/26 to a record 178.848 million bags. However, this global growth masks divergent trends: arabica production is expected to decline -4.7% to 95.515 million bags, while robusta production is projected to surge +10.9% to 83.333 million bags. This expected robusta acceleration reflects Vietnam’s dominant position, as FAS forecasts Vietnam’s 2025/26 coffee output will rise 6.2% year-over-year to a 4-year high of 30.8 million bags.

Against this supply expansion, global ending stocks are forecast to decline -5.4% from 21.307 million bags in 2024/25 to 20.148 million bags in 2025/26, suggesting that production growth will be consumed by robust demand. Vietnam’s coffee sector continues to expand its capabilities, with the Vietnam Coffee and Cocoa Association indicating that 2025/26 output could reach 10% above the prior crop year if favorable weather conditions prevail.

Meanwhile, global coffee exports through October of the current marketing year fell -0.3% year-over-year to 138.658 million bags according to the International Coffee Organization, indicating that recent production expansions have not yet translated into explosive export growth.

Conclusion: Coffee Markets Caught Between Supply Growth and Structural Support

The coffee commodity complex remains in transition, with arabica finding support from Brazil’s weather patterns and currency strength, while Vietnam’s robusta exports continue to weigh on near-term prices. The expectation of record global coffee production in 2025/26 will likely maintain price pressure over coming months, although inventory constraints and weather volatility could provide periodic support to values. Traders monitoring coffee should track Brazil’s rainfall patterns closely alongside Vietnam’s export activity, as these two factors will likely continue directing price discovery in the quarters ahead.
