Coffee Market Faces Tightening Supply Risks as ICE Volatility Intensifies (14 August 2026)
Arabica coffee futures on ICE Futures U.S. ended Friday's session with a mixed performance, as the nearby September and December contracts advanced while more distant positions remained under pressure. The market was heavily influenced by technical factors, the expiration of September options and the ongoing rollover of positions into later delivery months, resulting in another session of significant volatility. September Arabica gained 500 points, or 1.50%, to close at 338.10 cents per pound after trading between 329.05 and 340.70 cents, while December advanced 150 points to settle at 314.30 cents, after reaching a high of 319.00 cents and a low of 308.95 cents. Despite the gains on Friday, December finished the week slightly lower, illustrating the uncertainty that continues to characterize the forward market. Trading volume in New York reached approximately 49,069 lots, considerably above the previous session, while the September-December spread widened sharply to 23.80 cents per pound, compared with 20.30 cents previously. The September-March spread also increased to 34.80 cents, while December-March widened to 11.10 cents. These unusually large differentials reflect the combination of nearby supply concerns, declining liquidity in the September contract and continued position rollovers.
The price action during Friday's session also demonstrated how quickly sentiment can change. December futures opened around 312.00 cents per pound and initially attracted buying interest, climbing steadily to an intraday high of 319.00 cents. However, once prices reached that level, selling became increasingly consistent and the market reversed direction, eventually falling to 308.95 cents before recovering part of the decline into the close. The behavior of the September contract was similarly volatile, with prices moving through an 11.65-cent range before finishing substantially higher. With the September options expiring on Friday and the first notices for the contract approaching, technical positioning is expected to remain an important source of volatility during the coming sessions. December Arabica currently faces resistance around 319.22, 324.13 and 329.27 cents per pound, while support is located near 309.17, 304.03 and 299.12 cents. As trading activity gradually shifts toward December and later contracts, the market will increasingly look to these levels to determine whether the recent recovery can develop into a broader upward movement or whether prices will return to the lower end of the recent trading range.
Behind the technical volatility, however, the fundamental picture is becoming increasingly important. One of the strongest signals continues to come from ICE-certified Arabica inventories, which fell by another 4,985 bags on Friday to 231,445 bags. This marked the 37th consecutive trading day of declines and leaves certified stocks dramatically below the level seen one year ago, when they stood at approximately 726,661 bags. Inventories have fallen consistently throughout 2026, including substantial reductions in June and July, and the current level represents an extremely limited supply buffer for a market that is already dealing with uncertainty in several producing countries. The continued decline in certified stocks is particularly significant because these inventories represent coffee that can be made available against exchange delivery requirements. With stocks already at exceptionally low levels, any disruption affecting the physical flow of coffee has the potential to produce a much stronger reaction in futures prices.
The situation in Brazil is adding another layer of uncertainty. The country's physical Arabica market remains active, with buyers showing strong interest across different grades, but producers are generally reluctant to accept the price bases being offered. The sharp daily fluctuations in New York make it difficult for buyers and sellers to establish mutually acceptable prices, and many producers are choosing to sell only enough coffee to meet immediate financial commitments while waiting for a clearer picture of the market. The stronger U.S. dollar has improved returns in Brazilian reais, with the dollar closing Friday at approximately R$5.22, compared with R$5.08 a week earlier. September Arabica futures translated into roughly R$2,334.59 per 60-kg bag, up considerably from the previous week's equivalent value. Nevertheless, the improvement in local-currency prices has not yet resulted in a significant increase in producer selling, reinforcing the impression that farmers remain concerned about future availability and the possibility of further price appreciation.
Brazilian export figures provide additional evidence of the changing supply environment. According to Cecafé, Brazil exported approximately 14.97 million bags of Arabica during the first seven months of 2026, a decline of 16.70% compared with the same period of 2025. July was particularly weak, with Arabica shipments totaling 1.82 million bags, the lowest volume recorded for the month since 2018. Total coffee exports were more resilient because Robusta shipments increased sharply, but the decline in Arabica exports remains important for the global balance. August shipments have shown stronger activity than during the same period of July, indicating that Brazilian export flows remain active, but this improvement does not remove the concerns surrounding the size and quality of the current crop. The contrast between Arabica and Robusta exports is especially relevant because it shows that the overall Brazilian export numbers can remain relatively firm even while the availability of Arabica becomes increasingly restricted.
Attention is now turning toward the magnitude of the losses in Brazil's current production and the potential consequences for the next crop. Market estimates suggest that the 2026 harvest could be between 10% and 20% smaller than previously expected. Based on production estimates of around 68 million bags, this would imply a potential shortfall of approximately 6.8 million to 13.6 million bags. While the exact size of the loss remains uncertain, market participants increasingly agree that production has been affected significantly by unfavorable weather and reduced productivity. The focus is therefore shifting from determining whether there has been a crop loss to estimating how large that loss will ultimately be. This distinction could become increasingly important over the next several months, as a clearer assessment of production will influence both futures pricing and the willingness of producers and exporters to release coffee into the international market.
Weather is also becoming an increasingly important factor for the next production cycle. Brazil has experienced unusually warm conditions for the middle of winter, with some coffee-growing areas potentially reaching temperatures above 35°C. While the immediate impact of these temperatures remains difficult to quantify, the market is already looking ahead to the flowering period expected from September onward. The possibility of a strong El Niño developing during the September-October period is adding another element of uncertainty because changes in rainfall and temperature patterns could affect flowering, fruit development and ultimately the productivity of the following crop. Consequently, traders are not only assessing the damage already suffered by the current harvest but are also beginning to consider the possibility that adverse weather could reduce production again in the next cycle.
The supply situation has become even more complicated following the powerful earthquake in Colombia's main coffee-growing region. The magnitude 7.4 earthquake caused deaths, landslides and significant damage to roads, warehouses and processing infrastructure across the so-called Coffee Axis. The disruption is particularly important because Colombia is one of the world's major Arabica suppliers and an important source of coffee for the United States. According to market participants, the normalization of coffee logistics could take approximately two weeks, although damaged processing facilities may require considerably more time to return to full operation. Buenaventura port has gradually resumed some activities, but transporting coffee from producing areas to the port remains difficult, while several warehouses and processing facilities have suffered structural damage. The temporary reduction in Colombian shipments comes at an especially sensitive moment because global buyers are already facing extremely low ICE-certified Arabica stocks. As a result, even a temporary logistical disruption can have a disproportionate impact on market sentiment and nearby availability.
The Robusta market is also facing supply concerns, particularly in Vietnam. Data cited from Vietnamese authorities indicate that the country exported approximately 26.34 million bags during the first ten months of the 2025/26 crop year. Based on estimates of beginning stocks, production, exports and domestic consumption, available coffee before the arrival of the new crop may have fallen to around 500,000 bags. Vietnam's new harvest is expected to begin in October, but meaningful volumes are not expected to reach the international market until November. Weather conditions are adding further uncertainty, with reports of drought in some parts of the Central Highlands and excessive rainfall in others. Some farmers in major producing provinces are already anticipating significant production declines for the next season. Although these developments primarily affect Robusta, they remain relevant to the broader coffee market because a reduction in Robusta availability could encourage greater substitution toward Arabica, potentially increasing demand for an Arabica market that is already dealing with tight certified inventories.
Despite these fundamental concerns, London Robusta futures ended Friday under pressure. The September contract fell approximately $45 per ton to around $3,621, while November also declined, resulting in a significant weekly loss. Certified Robusta stocks, however, have been moving in the opposite direction from New York Arabica, with inventories reaching their highest level in several months at more than 4,350 lots. This divergence illustrates the different supply conditions facing the two markets. While Robusta currently has a more comfortable exchange-stock position, Arabica inventories in New York remain exceptionally tight, making the latter more vulnerable to any disruption in physical supply.
Speculative positioning is providing another bullish element to the market. The latest CFTC report, based on positions held as of August 11, showed that large funds increased their net long exposure to approximately 27,206 contracts, compared with 26,014 contracts in the previous report. Their positions consisted of 45,768 longs against 18,482 shorts, while commercial participants increased their net short position to approximately 29,359 contracts. Total open interest also increased during the period. Although positioning alone cannot determine the direction of prices, the increase in speculative long exposure suggests that funds are becoming more willing to maintain bullish exposure despite the market's substantial volatility. This positioning becomes particularly relevant when combined with the continuing decline in certified stocks and the growing number of supply-related uncertainties.
The physical market therefore remains caught between strong buyer interest and limited willingness from producers to sell aggressively. In Brazil, growers are holding back coffee because of uncertainty over future prices, while buyers are attempting to secure supplies in an environment where New York futures can move several cents in a single session. Colombia is facing temporary logistical restrictions, Vietnam is approaching the end of its available stocks before the new crop, and Brazil is dealing with concerns over both the size and quality of its production. At the same time, the global market has very little room for unexpected supply disruptions because ICE-certified Arabica stocks have already fallen to exceptionally low levels.
