Coffee Rebounds as Weather Risk Returns to the Price Equation (28 September 2026)

• December Arabica gained 10.15 cents, or 3.64%, to settle at 288.75 cents per pound after briefly trading above 290 cents.
• November Robusta rose $45 to $3,412 per metric ton, with the nearby spread retaining a $25 premium over January.
• ICE-certified Arabica stocks declined by 1,101 bags to 253,203 bags, keeping inventory availability firmly in focus.
• Hail in southern Minas Gerais, heat in Brazil and the prospect of an exceptionally strong El Niño have increased uncertainty around the 2027 crop, although confirmed damage remains localized.
• Brazil's active export flow and expectations for a constructive Vietnamese harvest continue to provide a counterweight to the weather premium.

Coffee futures opened the week with their strongest recovery attempt in several sessions, as renewed speculative buying combined with growing concern about crop weather in several producing regions. The move restored a more constructive short-term tone in New York, but it did not settle the larger debate over whether the recent sell-off has ended or merely paused.

December Arabica advanced 10.15 cents, or 3.64%, to settle at 288.75 cents per pound. The contract traded across a wide 14.45-cent range, from 277.05 to 291.50 cents, and briefly moved above the psychologically important 290-cent level before giving back part of the gain. March rose 9.65 cents to 280.90 cents, leaving December at a premium of 7.85 cents. Total New York volume reached 33,348 contracts.

Robusta also strengthened in London. November gained $45 to close at $3,412 per metric ton, while January added the same amount to $3,387. November ranged between $3,331 and $3,438, and its premium over January stood at $25. Total London volume reached 25,509 contracts.

A technical rebound, with weather as the catalyst

The scale and speed of Monday's Arabica rally suggest that the move involved both fresh buying and the covering of bearish positions established during the recent decline. Repeated buying interest in the broader 268 to 277-cent area helped stabilize the market, while the close above 280 cents improved the near-term chart structure.

The recovery is not yet a confirmed trend reversal. December closed below its session high and failed to hold above 290 cents, showing that selling interest remains active at higher levels. The first important resistance is near 294.48 cents, followed by 300.22 and 308.93 cents. On the downside, 280.03 is the first level to monitor, followed by 271.32 and 265.58 cents. Holding above 280 and securing a close beyond 294.50 would strengthen the case for a broader recovery. A return below 280 would leave the market vulnerable to another test of the recent lows.

Weather supplied the immediate fundamental justification for the rally. Traders are increasingly evaluating the condition of flowering and early fruit development in Brazil, the potential consequences of El Niño in Colombia and the production outlook ahead of Vietnam's new harvest. This combination has made it harder for the market to treat current supply availability as a complete guide to prices several months from now.

Brazil's hail reports raise concern, but losses are still unclear

Hail was reported on Monday in coffee-growing areas of southern Minas Gerais, including Poço Fundo, São João da Mata, the Paiolinho district and rural parts of Campestre. The timing is sensitive because coffee trees in parts of the region are flowering, when physical damage to blossoms and branches can reduce the number of cherries available for the next crop.

Initial accounts, however, are mixed. Some producers reported damage to coffee plants, while municipal officials in São João da Mata said no losses had been confirmed there. There is not yet a reliable estimate of the affected area or the potential production impact. The market therefore faces a localized weather event with uncertain consequences, not evidence of a broad regional crop failure.

Heat is a wider concern. High temperatures across south-central Brazil can accelerate moisture loss and interfere with fruit set if flowering is not followed by adequate and well-distributed rain. The next rounds of precipitation will be more important than the initial flowering itself. Good follow-up rain would help trees retain newly formed fruit, while a renewed dry spell could convert current concern into a more measurable production risk.

For prices, the bullish factor is presently uncertainty rather than a verified reduction in supply. Damage surveys and the distribution of rain during the next several weeks will determine whether the weather premium expands or fades.

Extreme El Niño risk shifts attention toward 2027

The climate outlook has also become more important. NOAA's September assessment described El Niño as strengthening and assigned a 75% probability that the Relative Oceanic Niño Index would exceed 2.5 degrees Celsius during October through December. If that forecast is realized, the event would rank as the strongest in the agency's record beginning in 1950.

That distinction matters. A record-strength event is a forecast, not an already observed outcome, and the severity of the Pacific temperature anomaly does not guarantee equally severe effects in every coffee-producing region. Even so, the probability of an extreme event increases the market's sensitivity to rainfall, heat and water availability across Brazil, Colombia, Vietnam and other origins.

Colombia is already preparing for drier and warmer conditions. The National Federation of Coffee Growers has framed El Niño as an active challenge across the country's 23 coffee-producing departments. Its response includes a 40 billion Colombian peso fertilization program financed through the Coffee Price Stabilization Fund, intended to improve plant nutrition before the driest part of the cycle.

The federation has also raised the reference price for lower-quality pasilla coffee from COP 10,000 to COP 12,000 per kilogram and widened the allowance for borer-damaged beans recognized within the excelso grading framework. These measures are designed to protect producer income if dryness reduces bean quality or increases pest pressure. Continued monitoring for coffee berry borer will be particularly important, since hot and dry conditions can favor its spread.

For Colombia, the immediate risk is not necessarily a sudden collapse in national production. The more plausible early effects are weaker cherry filling, smaller or shriveled beans, pressure on the secondary crop and higher quality-management costs. The FNC's Purchase Guarantee and technical extension network should provide a degree of commercial and agronomic support, but they cannot eliminate the underlying weather exposure.

Current supply still restrains the bullish case

Weather risk is rising at the same time that fresh coffee is moving through the physical market. Cecafé reported Brazilian shipments of 2.807 million bags through September 25, including 2.018 million bags of Arabica, 576,930 bags of Robusta and 213,001 bags of soluble coffee. The total was 4.5% lower year over year, but the volume remains large enough to remind traders that near-term availability has not disappeared.

Brazil's domestic Arabica market remained quiet, with producers reluctant to accept lower bids after the decline in futures. Quality coffee in southern Minas Gerais was indicated near R$1,780 per 60-kilogram bag, but limited seller participation kept transaction volume subdued. A stronger US dollar against the Brazilian real can improve local export returns and encourage hedging, which may restrict gains in New York if futures continue to rise.

Certified inventories tell a more supportive story. ICE Arabica stocks fell by 1,101 bags to 253,203 bags, showing that the replenishment anticipated after Brazil's harvest has yet to become decisive. Further stock withdrawals would strengthen the market's nearby supply concern, while a sustained inflow of newly certified coffee would reduce it.

Vietnam presents another counterweight to the bullish weather narrative. Recent rainfall in the country's main Robusta areas has not been reported to have materially damaged yield prospects, and harvesting is expected to begin within weeks. Expectations for solid productivity and quality could bring additional coffee into commercial channels and help rebuild inventories. The key question is whether those supplies arrive smoothly and in sufficient volume before El Niño begins to alter conditions later in the crop cycle.

Starbucks restructuring

Away from futures and origin markets, Starbucks plans to close about 250 underperforming stores in North America as part of its broader turnaround. The closures represent roughly 1% of its regional network and are expected to contribute to approximately $300 million in restructuring costs. The company is simultaneously investing in retained locations and still expects net global store growth.

The decision should therefore be read primarily as a portfolio and profitability measure, not as direct evidence of a collapse in coffee consumption. It does, however, illustrate the pressure on large retailers to improve store economics while labor, property and commodity costs remain elevated and competition intensifies.

What the market will watch next

Monday's rally changed the short-term tone, but the next move will depend on confirmation from both charts and fundamentals. A sustained break above 294.50 cents would put 300 cents back into view for December Arabica. Failure to hold the 280-cent area would suggest that the rebound was mainly corrective.

Beyond price levels, traders will focus on follow-up rainfall after Brazil's flowering, verified hail damage in southern Minas Gerais, NOAA's El Niño updates, the pace of ICE stock changes, Brazilian producer selling and the opening of Vietnam's harvest. Colombia's rainfall pattern and pest pressure will also become more relevant as the dry season develops.

The central tension is clear. Brazil and Vietnam can provide meaningful near-term supply, but the market is increasingly reluctant to discount risks to the crops that will determine availability in 2027. Monday's advance tilted the immediate balance toward buyers. It did not resolve the contest between current supply and future weather risk.
