Coffee markets are sending mixed signals as arabica prices test a 2.5-week high while robusta remains under pressure from improving supply prospects and currency-driven Brazilian export selling. December arabica futures are being supported by concerns over dry conditions in Brazil during the critical flowering stage for the 2026/27 crop, while November robusta continues to face heavier supply pressure.
The immediate weather outlook is becoming increasingly important for arabica. Rainfall prospects across Minas Gerais, Brazil’s largest arabica-producing region, are limited in the near term, raising concerns about flowering and the development of the next crop. At the same time, broader supply estimates remain bearish, with the International Coffee Organization and USDA both forecasting record global production.
The market is therefore balancing a potentially tighter near-term arabica supply outlook against evidence that global coffee availability is expanding. The direction of prices will depend increasingly on Brazilian flowering conditions, export flows, inventories and whether the expected record global crop materializes.

Current Coffee Price Action
December arabica futures are holding near a 2.5-week high after gaining 0.70 cents, while November robusta futures remain slightly lower.
The divergence reflects different fundamental conditions between the two markets. Arabica is receiving support from concerns about Brazil’s upcoming flowering period, while robusta is facing rising inventories and stronger supply expectations from Vietnam.
The Brazilian real is another important short-term factor. Its decline to a six-week low against the U.S. dollar encourages Brazilian producers to sell coffee into international markets because dollar-denominated revenues translate into more local currency.
That currency effect is limiting the upside generated by weather concerns.
Brazil Weather Becomes Critical for the 2026/27 Crop
Brazil’s flowering period is becoming the most important near-term supply variable for arabica.
Meteorological forecasts indicate limited rainfall in Minas Gerais over the coming week, while concerns surrounding the timing and distribution of rainfall could affect flowering and subsequent cherry development.
Recent rainfall has provided some support to crop conditions. Somar Meteorologia reported 29.7 mm of rain in Minas Gerais during the week ending September 27, equivalent to 112% of the historical average. The question now is whether rainfall remains adequate through the remainder of the flowering period.
A prolonged dry spell would increase the risk premium in arabica futures, while sustained beneficial rainfall would reinforce expectations for another large Brazilian crop.
Brazil Crop Estimates Remain Bearish
Despite near-term weather concerns, Brazil’s broader production outlook remains large.
Conab has raised its 2026 Brazilian coffee production estimate to 67.6 million bags from 66.7 million previously. Arabica production is projected at 48.21 million bags, representing an increase of 34.8% from the previous year, while robusta production is expected to decline 6.6% to 19.39 million bags.
The size of the expected arabica crop remains an important counterweight to weather-driven price strength.
If the 2026/27 flowering period develops normally, the market could increasingly focus on the prospect of abundant Brazilian supply rather than the current weather risk.
Global Coffee Supply Remains the Major Bearish Factor
The International Coffee Organization estimates that global coffee production for 2025/26 will rise 4.4% year-over-year to a record 183.6 million bags.
At the same time, consumption is projected to decline 0.9% to 180.6 million bags, leaving the global market with an estimated 3 million-bag surplus.
This represents a major shift in the fundamental balance after several years in which production constraints and tight inventories supported coffee prices.
The USDA’s latest outlook reinforces the supply story, with global coffee production for 2026/27 projected at a record 189.7 million bags, an increase of 6.0% year-over-year. Global ending stocks are also forecast to increase by 1.9 million bags to 26.3 million bags.
Brazil Exports Add Physical Supply
Brazil’s current harvest is moving into the export market, increasing the availability of physical coffee.
Cecafe reported August coffee exports of 4.155 million bags, an increase of 31% year-over-year and a record for the month. Arabica exports increased 26% to 2.87 million bags, while robusta exports surged 54% to 953,592 bags.
Higher export volumes provide a direct source of supply for the international market and can limit futures rallies when producer selling increases.
The weaker Brazilian real adds another incentive for exporters and producers to convert coffee into dollar revenue.
Vietnam Supply Weighs on Robusta
Vietnam remains an important bearish influence on robusta prices.
Vietnamese coffee exports from January through August increased 13.7% year-over-year to 1.33 million metric tons. Full-year 2025 exports also increased 17.5% to 1.58 million metric tons.
The 2025/26 Vietnamese crop is projected at approximately 1.76 million metric tons, or 29.4 million bags, representing a four-year high.
Recent rainfall has also improved soil moisture across Vietnam’s Central Highlands, supporting expectations for better cherry development in the country’s main robusta-growing region.
The combination of larger export availability and improved growing conditions is keeping pressure on robusta.
Inventories Create a Major Arabica-Robusta Divergence
Coffee inventories are producing an important split between arabica and robusta.
ICE arabica inventories remain historically low. Stocks reached a 27-year low of 217,646 bags on September 15 and have since recovered to 255,721 bags.
Even with the recent increase, the relatively low inventory level provides a cushion against aggressive selling and means unexpected supply disruptions could generate a stronger price response.
Robusta inventories tell a different story. ICE robusta stocks have risen to 5,398 lots, the highest level in 10 months.
The contrasting inventory positions help explain why arabica is showing greater resilience while robusta remains more exposed to supply-driven selling.
El Niño Adds Longer-Term Weather Risk
Weather uncertainty extends beyond the immediate Brazilian rainfall outlook.
An emerging El Niño pattern could alter rainfall patterns across major coffee-producing regions. Concerns that El Niño could delay Brazilian rains during September and October create an additional risk for flowering.
The potential impact extends beyond Brazil. Changes in rainfall and temperatures can affect coffee production across both South America and Asia.
However, the effect on prices will depend on actual weather developments rather than the existence of the climate pattern alone. Traders will therefore continue to monitor rainfall forecasts and soil conditions across Brazil and Vietnam.
Bullish Sentiment
- Brazilian flowering faces weather uncertainty: Limited near-term rainfall in Minas Gerais could threaten the development of the 2026/27 arabica crop.
- Arabica inventories remain historically low: ICE stocks remain close to multi-decade lows, leaving the market sensitive to supply disruptions.
- El Niño creates additional weather risk: Potential changes in Brazilian rainfall during the flowering period could increase production uncertainty.
- Arabica production carries greater weather sensitivity: The large expected Brazilian crop still depends on successful flowering and subsequent growing conditions.
- Coffee prices are already reacting to weather risk: Arabica futures reaching a 2.5-week high indicates that weather concerns can temporarily outweigh the broader surplus narrative.
Bearish Sentiment
- Global production is expected to reach record levels: Both the ICO and USDA project exceptionally large global coffee supplies.
- Brazil’s 2026 crop estimate has increased: Conab now expects 67.6 million bags, with arabica production projected to rise sharply.
- Brazilian exports are accelerating: August exports reached a record monthly level, increasing physical availability.
- Vietnamese supply is improving: Higher exports and better soil moisture are strengthening the robusta supply outlook.
- Global inventories are expected to increase: The USDA forecasts world ending stocks rising to 26.3 million bags in 2026/27.
Price Forecast: What Traders Are Watching
The immediate direction of arabica futures will depend heavily on Brazilian flowering conditions.
A continuation of dry weather across Minas Gerais would increase concern over the 2026/27 crop and could keep a weather premium embedded in arabica prices. A return to consistent rainfall, however, would shift attention back toward the much larger production estimates from Brazil and the USDA.
For robusta, the supply picture remains more clearly negative. Rising ICE inventories, stronger Vietnamese exports and improving crop conditions provide fewer reasons for a sustained price recovery unless a new supply disruption emerges.
The key market question is therefore whether weather risk can remain significant enough to offset the record global production outlook.
Supply Outlook
Global coffee supply is expected to expand substantially into the 2026/27 season.
The USDA’s 189.7 million-bag global production forecast represents a record level, while Brazil is expected to deliver a major increase in arabica production. Vietnam is also providing additional robusta supply.
The primary uncertainty is weather. A significant deterioration in Brazilian flowering conditions could reduce expected production and force the market to reassess the current surplus outlook.
Demand Outlook
Demand is currently less supportive than the supply side of the market.
The ICO expects global consumption to decline 0.9% in the 2025/26 season, contributing to an estimated 3 million-bag surplus.
For prices to sustain a stronger recovery, demand would need to improve enough to absorb the anticipated increase in production. Otherwise, rising availability and inventories could continue to cap rallies.
Market Outlook for the Coming Sessions
Coffee prices are entering a period in which weather and supply estimates are likely to compete for market attention.
Arabica has the stronger immediate fundamental support because Brazil’s flowering stage creates a genuine production risk and ICE inventories remain historically low. However, the longer-term supply outlook remains bearish, with Brazil, Vietnam and global production forecasts all pointing toward increased availability.
Robusta faces a heavier supply burden as Vietnamese exports improve and ICE inventories reach a 10-month high.
The next major signal for arabica will be Brazilian rainfall. Traders will be watching whether Minas Gerais receives enough moisture to protect flowering and support the large crop currently expected for 2026/27. At the same time, producer selling, the Brazilian real and physical export flows will remain important variables.
Currency Hedger View
Coffee is particularly sensitive to currency movements because Brazil and Vietnam are major exporters whose producers receive revenues linked to the U.S. dollar while operating with significant local-currency costs.
A weaker Brazilian real can encourage producers to increase export sales because dollar-denominated coffee revenues translate into more reais. This can increase physical supply and place additional pressure on futures prices even when weather concerns are supportive.
For coffee buyers, roasters and international traders, the combination of coffee prices and USD/BRL movements can therefore have a direct impact on landed costs and margins.

Analysis Louis Roche – Today Markets
Coffee markets are caught between two very different forces. Near-term Brazilian weather risk is supporting arabica as the 2026/27 crop enters its critical flowering period, while the broader global production outlook remains heavily bearish.
The record global production forecasts from the ICO and USDA, combined with higher Brazilian exports and improving Vietnamese supply, point toward substantially greater availability. Yet the historically low level of ICE arabica inventories means that the market remains sensitive to any deterioration in Brazilian growing conditions.
The next phase of the market will therefore depend on whether weather risk becomes a genuine production threat or whether favourable conditions allow the large crop estimates to be realised. Arabica currently has more weather-driven support than robusta, but both markets remain exposed to the broader global supply outlook.
