Brazilian Weather Damage, Falling ICE Stocks and Fund Short-Covering Support Coffee Prices (17 July 2026)

Coffee futures recovered on Friday, July 17, as weather-related damage in Brazil, declining ICE-certified inventories and continued short-covering by speculative funds provided support following the sharp losses recorded in the previous session.

The September Arabica contract in New York gained 7.70 cents, or 2.46%, to settle at 320.30 cents per pound after trading between 311.35 and 324.40 cents. The contract briefly moved above its first technical resistance at 321.57 cents before retreating from the session high. Despite Friday’s recovery, September ended the week 13.95 cents lower, recording its first weekly decline in six weeks.

Trading volume reached 27,871 contracts, the lowest level in ten sessions and 2,416 contracts below Thursday’s total. The reduced liquidity contributed to considerable intraday volatility, with prices moving sharply between gains and losses.

Robusta futures also recovered in London. The September contract rose by $80, or 2.1%, to settle at $3,877 per tonne after trading between $3,789 and $3,929. It finished the week $25 per tonne higher, equivalent to a gain of approximately 0.65%.

Although part of Friday’s advance reflected technical buying after the previous session’s decline, the market continues to receive fundamental support from concerns about Brazil’s harvest quality and the limited availability of immediately deliverable coffee.

Heavy rainfall, strong winds and hailstorms have caused significant losses in parts of São Paulo state, where the Arabica harvest remains underway. In Garça, growers report that large quantities of ripe coffee cherries have been knocked from the branches and onto wet soil.

Coffee collected from the ground generally suffers a reduction in quality and commercial value. Contact with damp soil can delay drying, increase the risk of fermentation and negatively affect the final beverage quality.

Producer José Carlos de Morais Filho, who manages approximately 370,000 coffee trees, estimates that around 40% of his production has already fallen to the ground. He expects affected coffee to be discounted by approximately R$400 per bag, potentially generating a total loss of around R$700,000.

Another producer, Ellaritta Crude, projects losses of approximately 40% across a 450-hectare rainfed farm. The estimated financial damage is around R$7,000 per affected hectare.

Farmers are operating harvesting machinery intensively to collect as much coffee as possible before additional weather systems arrive. Manual harvesting has also been introduced as an emergency measure. Although slower and more expensive, it has become one of the few viable options for saving ripe cherries that remain attached to the trees.

The losses reported in Garça are specific to individual farms and should not be treated as representative of Brazil’s entire crop. Nevertheless, they illustrate the uneven impact of the recent storms and reinforce concerns that the country may produce less high-quality Arabica than previously expected.

Cecafé President Márcio Ferreira said the rains occurred at an inappropriate stage of the season, during a period when harvesting normally accelerates under predominantly dry conditions. Weather before the harvest had been highly favourable, supporting expectations for a large crop with strong quality.

The rainfall is unlikely to eliminate the prospect of a good Brazilian harvest, but it may reduce the availability of cherry coffees and other higher-grade beans that compete with Colombian coffee and can meet New York exchange-delivery standards. Producers may also retain their best-quality coffee while evaluating the extent of the damage and future price developments.

Brazil’s National Supply Company, Conab, continues to forecast production of approximately 66.7 million 60-kilogram bags, which would represent a record crop. The national estimate remains an important bearish factor, but the market is increasingly distinguishing between total production and the availability of high-quality coffee suitable for premium consumption, export and exchange delivery.

Attention is also beginning to move toward the outlook for the 2026/27 crop. Reports citing the Brazilian Coffee Industry Association, ABIC, suggest that prolonged heat and irregular rainfall could reduce production by 15% to 20% compared with expectations if adverse weather persists. This remains a risk scenario rather than an established national forecast.

The most decisive period is likely to be the flowering season between September and October. Coffee trees require well-distributed rainfall after the dry season to produce concentrated and uniform flowering. Delayed or irregular precipitation, combined with excessive temperatures, could cause several separate flowering rounds.

Multiple flowerings can reduce fruit set, produce uneven bean development and create inconsistent ripening. This complicates harvesting and may affect both production and quality.

Brazil is better prepared for El Niño than during previous cycles. Producers have expanded irrigation, adopted more heat- and drought-resistant varieties and invested in modern plantation-management systems. These improvements reduce dependence on rainfall and allow farmers to respond more quickly to adverse conditions.

However, the level of exposure varies substantially between producing regions. In Espírito Santo, Brazil’s largest Conilon-producing state, growers are concerned about longer intervals between rainfall events and precipitation becoming concentrated into short periods of high intensity.

High temperatures may be particularly damaging to Conilon trees. According to industry representatives, plant metabolism begins to slow when temperatures exceed approximately 27°C and can almost cease around 35°C. In such conditions, heat stress can become more damaging than the direct effects of insufficient rainfall.

Rondônia appears better protected because much of its Robusta production is irrigated, while some farms also use water-based cooling systems. The Rondônia Coffee Association expects the state’s crop could reach approximately 3 million bags, above Conab’s projection of 2.77 million.

Alongside the weather concerns, the latest Commitments of Traders report showed that large speculative funds increased their net long position in Arabica futures by approximately 8.6% during the week ending July 14.

Funds held 26,499 net long contracts, compared with 24,398 one week earlier. However, the increase did not result from new bullish buying. Gross long positions declined by 1,602 contracts to 47,885, while gross short positions fell by a larger 3,703 contracts to 21,386.

Over the previous five weeks, fund short positions declined by approximately 52%, from 44,375 to 21,386 contracts. Total open interest also fell by 5.76%, from 242,253 to 228,276 contracts, confirming that the rise in net length was primarily driven by short-covering and position liquidation.

The reduction in exposure reflects the effects of extreme price volatility and a reported 168% increase in margin requirements, which forced some participants to close positions or leave the market.

Commercial firms moved in the opposite direction, increasing their net short position by approximately 7.2% to 27,983 contracts. They held 77,857 long positions and 105,840 short positions.

Open interest in the September Arabica contract declined by 5,889 lots during the week but remained at 65,253 contracts. December open interest reached 56,237 contracts, leaving it only 9,016 below September more than a month before the normal rollover period.

The early movement toward December may reflect a combination of concern about nearby availability and traders reducing September exposure ahead of the delivery period, options expiration and index-fund rollovers.

Physical tightness remains most visible in ICE-certified Arabica stocks. Inventories declined for the 17th consecutive trading session on Friday, falling by another 1,309 bags to 332,945 bags.

Certified stocks have decreased by approximately 44,520 bags, or 11.8%, since the beginning of July. No coffee had been awaiting certification for seven consecutive sessions, indicating that there was no immediate pipeline of newly graded beans available to offset withdrawals.

Inventories were only around 30,700 bags above the historical low recorded in March 1999. If the recent pace of withdrawals continues, certified stocks could fall below 300,000 bags within several trading sessions.

The tightening nearby supply is also reflected in the futures curve. The September contract ended Friday at a premium of 16.50 cents over December, up from 15.35 cents in the previous session. The September–March premium widened to 22.70 cents, while the December–March spread increased to 6.20 cents.

These inverted spreads indicate that the market continues to assign a substantial premium to coffee available for immediate delivery.

Brazilian exports were also running below expectations during the first half of July. According to Cecafé, shipments through July 17 reached 1,083,988 bags, representing an 11% decline based on the daily average.

The total included 771,521 bags of Arabica, 164,104 bags of Robusta and 148,363 bags of soluble coffee. Requests for certificates of origin totalled 1,508,691 bags, down 12.8%, while current shipment projections indicate that July exports could remain below 2.5 million bags.
