Coffee Market Under Pressure as Brazilian Harvest Accelerates, but Tight Physical Supply Continues to Support Nearby Contracts (18 May 2026)
Coffee futures extended their decline on Monday, May 18, as both Arabica and Robusta posted notable losses amid accelerating harvest activity in Brazil, renewed speculative selling, and expectations of improved global supply. Although the market tone was clearly bearish, several structural indicators, including widening nearby spreads and very low certified inventories, continue to signal that physical coffee availability remains tighter than outright futures prices suggest.
On ICE Futures US, the July 2026 Arabica contract settled at 264.20 cents per pound, down 2.70 cents on the day after briefly trading above the key psychological threshold of 270.00 cents per pound. The contract reached an intraday high of 270.15 cents before attracting substantial selling, reversing sharply and touching a low of 263.45 cents. September 2026 closed at 256.75 cents per pound, down 3.35 cents, while December 2026 fell 3.65 cents to 249.80 cents per pound. In London, July 2026 Robusta futures settled at $3,306 per metric ton, down $59, with September and November contracts falling to $3,175 and $3,100 per ton, respectively. July Robusta briefly traded below $3,300, extending a decline of roughly $300 per ton over the past three sessions.
The principal bearish factor remains the rapid progress of the Brazilian harvest. As fresh crop supplies begin moving into warehouses and export channels, market participants anticipate a larger flow of physical coffee reaching the global market over the coming weeks. This expectation has prompted increased selling by speculative funds, particularly after Arabica failed to sustain prices above 270 cents per pound. Several private crop forecasts have also been revised upward, reinforcing the perception that Brazil may produce a larger crop than previously anticipated. While some traders question the methodology behind these estimates, the market is treating the possibility of greater supply as a legitimate reason to reduce long exposure.
Adding to the bearish sentiment, Rabobank projected Brazil’s 2026/27 coffee crop at 73.3 million 60-kilogram bags, according to a Reuters report released on May 18. The estimate points to one of the largest Brazilian coffee crops on record and strengthens expectations that global coffee supplies will improve substantially over the coming season. The forecast contributed to increased selling pressure as market participants reassessed the balance between currently tight inventories and the prospect of abundant new production.
Weather conditions in Brazil remain a critical variable and continue to be closely monitored. Forecasts indicate that a cold front will move across parts of southeastern Brazil, bringing localized rainfall and increased cloud cover. At this stage, temperatures are expected to remain within seasonal norms, and the probability of damaging frost is considered low. Nevertheless, because the market is entering Brazil’s winter period, any unexpected drop in temperatures could quickly shift sentiment and trigger a sharp recovery in prices. For now, weather is acting as a background risk factor rather than an immediate bullish catalyst.
Despite the decline in futures prices, exchange-certified inventories remain exceptionally tight. Arabica certified stocks fell by 3,628 bags to 462,777 bags, with an additional 3,390 bags awaiting grading. Robusta certified stocks declined to 3,631 lots, the lowest level in approximately two years. These low inventory levels suggest that the physical market continues to operate with limited deliverable supplies, even as futures prices react negatively to the prospect of larger upcoming harvests.
Commitments of Traders data show that investment funds still maintain a sizable net long position in Arabica coffee. Gross long positions stand at 44,974 contracts, while gross shorts increased to 19,946 contracts, reducing the net long to 25,028 contracts. The increase in short positions indicates that some funds are becoming more defensive and are positioning for further downside. In Robusta, funds expanded their net long position to 13,789 lots, although heavy selling by producing origins during recent rallies has limited bullish momentum.
One of the most important developments on Monday was the widening of nearby calendar spreads despite the drop in flat prices. In Arabica, the July/September spread widened to 7.45 cents and the July/December spread to 14.40 cents. In Robusta, the July/September spread widened to $131 per ton and the July/November spread to $206 per ton. This spread behavior suggests that near-term supplies remain tight and that commercial participants continue to value prompt coffee deliveries, even as the broader market prices in increased supply later in the season.
Attention is also turning to July Arabica options, which expire on June 12. Open interest is concentrated around the 270-cent and 250-cent put strikes, with thousands of contracts outstanding. This concentration may influence price action as expiration approaches, as market participants adjust hedges and speculative positions around these levels.
From a technical perspective, the inability of July Arabica to hold above 270 cents per pound reinforces the current downward trend. Immediate support is located at 262.30 cents, followed by 257.70 and 249.85 cents. Resistance levels are seen at 274.75, 282.60, and 287.20 cents. A decisive break below 255 cents would increase the probability of a deeper correction toward the 233 to 235 cent region. Conversely, if prices stabilize above current support, a short-covering rebound toward 280 cents remains possible.
Brazilian export performance remains robust. According to the Brazilian Coffee Exporters Council (Cecafé), shipments through May 14 totaled 1.001 million bags, including 723,665 bags of Arabica, 194,213 bags of Robusta, and 83,570 bags of soluble coffee. The pace is broadly stable compared with the same period last year, indicating that Brazil continues to supply the international market at a strong rate.
Currency movements offered little support to prices. The U.S. dollar weakened against the Brazilian real, briefly testing the BRL 5.00 level. A stronger real typically reduces the incentive for Brazilian producers to sell aggressively, but this supportive effect was outweighed by harvest pressure and speculative liquidation.
