Arabica sell-off approaches 20% as Brazilian supply pressure builds, while flowering weather remains a risk (22 September 2026)

Key takeaways

• ICE New York December Arabica settled at 272.30 cents/lb, down 4.10 cents on the session and 63.20 cents, or 18.8%, below its August 25 close. The contract traded as low as 271.30 cents, its weakest level in almost three months.
• London November Robusta fell to $3,260/t, while nearby calendar spreads compressed sharply. Both outright price action and the flattening front of the curve indicate that the market is removing some of the scarcity premium previously embedded in nearby supply.
• Brazilian export availability remains substantial. Cecafé recorded 2.304 million bags dispatched by September 22, while certificates of origin had already reached 2.974 million bags, leaving a sizeable pipeline of coffee potentially moving toward export channels.
• Brazil's domestic market is recovering as retail coffee prices ease. Consumption reached 13.69 million bags during January-August, up 2.29% year on year, reversing part of the contraction recorded during the high-price environment of 2025.
• Weather remains the principal counterweight to the increasingly comfortable supply narrative. A potentially very strong El Niño, elevated temperatures and uneven rainfall around flowering could affect the next Brazilian crop, although official forecasts do not currently indicate a generalized drought across Minas Gerais.

Arabica extends the correction

The decline in Arabica accelerated again on Tuesday. December settled at 272.30 cents/lb, down 1.48%, after trading between 271.30 and 278.50 cents. From the August 25 close of 335.50 cents, the contract has now lost 63.20 cents, equivalent to approximately 18.8% in 19 trading sessions.

The scale and persistence of the decline are increasingly significant. Prices have moved from above 335 cents to the low 270s without establishing a durable recovery structure, while attempts to stabilize around 280 cents have so far failed. Tuesday's settlement below 275 cents therefore represents another deterioration in short-term technical structure.

The Arabica curve is weakening, but tightness has not disappeared

The December/March spread narrowed to +7.60 cents, from +7.95 cents previously, while December/May eased to +10.25 cents from +10.45 cents. March/May moved in the opposite direction, widening slightly to +2.65 cents.

The important point is that Arabica remains in backwardation. Nearby coffee continues to command a substantial premium over deferred delivery, which is inconsistent with the idea that the physical market has suddenly become oversupplied.

Certified stocks are beginning to rebuild

ICE Arabica certified stocks increased to 256,678 bags, while another 20,157 bags were awaiting certification. Of the coffee processed in the latest certification flow, 4,771 bags were approved while 5,212 bags of Brazilian coffee were rejected.

The direction is important. Certified stocks remain exceptionally low by historical standards, but the market is no longer dealing only with declining exchange inventories. Reuters reported earlier in September that major trading houses were moving significant quantities of Brazilian Arabica toward exchange warehouses, with potential deliveries large enough to materially rebuild certified inventories if the coffee successfully passes grading. At the time, certified stocks were around 220,000 bags, described as their lowest level in roughly 26 years.

That creates an asymmetric situation. Additional successful certifications would weaken one of the strongest bullish arguments that supported Arabica during the previous tight-supply phase. At the same time, the rejection of some Brazilian coffee demonstrates why pending certification should not automatically be treated as future certified stock.

Robusta is showing an even clearer erosion of nearby tightness

London November Robusta declined by $77/t to $3,260/t, a fall of approximately 2.3%. The contract reached $3,245/t during the session as the broader decline across coffee markets continued.

The more important development occurred in the spreads. November/January compressed from $25/t to $11/t, November/March from $33/t to $16/t, and January/March from $8/t to $5/t.

This represents a meaningful reduction in the premium attached to nearby Robusta availability. Backwardation has not disappeared, but the speed at which it is compressing indicates a market becoming considerably less concerned about immediate supply.

The Arabica-Robusta price differential also narrowed slightly to approximately 124.4 cents/lb. The premium remains historically substantial, but the latest movement shows that both markets are participating in the broader repricing of coffee supply rather than the weakness being confined to one variety.

Brazilian exports provide increasingly visible supply

Brazilian coffee flows are becoming one of the strongest fundamental arguments behind the sell-off.

According to Cecafé, cumulative September dispatches through September 22 reached 2.304 million 60-kg bags, consisting of approximately 1.687 million bags of Arabica, 452,000 bags of Conilon and 164,000 bags of soluble coffee. The comparable figure shown for the previous month was 1.657 million bags, meaning the current dispatch pace was approximately 39% higher.

Even more significant is the certification pipeline. Certificates of origin had reached 2.974 million bags, approximately 669,000 bags above recorded dispatches and 68% above the comparable previous-month figure shown by Cecafé. Certificates should not be interpreted as completed exports, but the difference indicates that additional coffee has already progressed through an important part of the export process.

This distinction matters. September exports are not merely reflecting beans already shipped earlier in the month. The certification data suggest that Brazil continues to have material coffee available for shipment, which could maintain export pressure into the remainder of September and beyond.

Brazilian demand is recovering, but supply remains the dominant story

Brazil's domestic coffee market is also improving. Reuters reported ABIC data showing retail consumption of 13.69 million bags between January and August 2026, up 2.29% from the corresponding period of 2025. During the second four-month period of the year, consumption increased 4.65% year on year to roughly 7 million bags.

The rebound follows a 5.4% contraction during the first eight months of 2025, when exceptionally high retail prices damaged consumer demand. ABIC now reports that raw-material availability has normalized and average retail prices have fallen across coffee categories. Traditional/Extra Strong coffee prices were 21.22% lower year on year in August, while soluble coffee prices declined 19.31%.

This is fundamentally constructive for consumption, but its market impact should not be overstated. Stronger Brazilian demand absorbs part of the country's increased availability, yet current export flows, the large 2026 crop and improving exchange-stock pipeline indicate that additional production is still finding its way into international channels.

Weather is the main challenge to the bearish supply narrative

The market should not interpret the current supply improvement as evidence that weather risk has disappeared.

Brazilian authorities currently see a greater than 90% probability that the September-November period will experience a very strong El Niño. INMET's latest spring outlook also expects temperatures above historical averages across large parts of Brazil during October-December.

For coffee, the issue is particularly relevant because the weather transition coincides with flowering and initial fruit setting for the next crop. High temperatures increase evapotranspiration and plant water requirements. Rainfall that triggers flowering but is followed by renewed dry conditions can reduce fruit set, while repeated isolated rain events can generate multiple flowerings and greater crop heterogeneity.

However, the regional distinction is critical. Some private forecasts have highlighted high temperatures and potentially insufficient rainfall in northern and central areas of Minas Gerais, including temperatures above 33°C in some locations. Yet the official INMET-INPE-Funceme spring forecast expects above-normal rainfall across center-south Minas Gerais during October-December, alongside above-normal temperatures.

The correct interpretation is therefore not that Minas Gerais is entering a generalized drought. The risk is rainfall distribution plus temperature. Northern and central areas could experience greater moisture stress, while important southern producing regions may receive adequate or above-average total precipitation but still face problems if rainfall arrives irregularly or is followed by periods of excessive heat.

Market perspective

The fundamental balance has shifted considerably from the environment that supported coffee prices earlier in the cycle.

Brazilian availability is high, export flows are accelerating, domestic raw-material supply has normalized and ICE Arabica stocks have begun moving away from extreme lows. At the same time, both Arabica and Robusta calendar spreads are losing part of their nearby scarcity premium. These developments provide a fundamental explanation for why the current decline has been more persistent than a conventional technical correction.

Nevertheless, the market has not transitioned into an obviously oversupplied structure. Arabica remains in backwardation, certified stocks remain extremely low in absolute historical terms, and Brazilian flowering weather introduces uncertainty over the next production cycle. The current market is therefore better characterized as a repricing from extreme scarcity toward improving availability, rather than as evidence that supply risk has disappeared.

Near-term price direction will depend on whether additional Brazilian coffee continues reaching export and exchange channels faster than weather concerns develop. Successful certification of substantial additional Arabica volumes would reinforce the bearish adjustment. Persistent heat combined with poorly distributed rainfall during flowering and fruit setting could eventually challenge it.

For December Arabica, 271-268 cents is now the immediate downside area to monitor. A decisive break would extend the correction beyond 20% from the August 25 reference close, although that percentage threshold has no predictive significance by itself. Conversely, a recovery above 275 cents followed by sustained trade through the 280-283 cent region would represent the first meaningful evidence that downside momentum is beginning to stabilize.

Until that occurs, the prevailing structure remains defensive: supply indicators are improving faster than the market is receiving evidence of damage to the next Brazilian crop. Weather remains a potentially important bullish risk, but at present it is a risk to the bearish narrative rather than proof that the narrative is wrong.
