Harvest Delays and Tight Supplies Keep Bulls in Control
Coffee futures extended their advance on Wednesday as concerns over near-term supply continued to outweigh expectations of a larger Brazilian crop later in the season. Both Arabica and Robusta markets finished firmly higher, supported by a slower-than-expected harvest in Brazil, persistently tight certified inventories, and ongoing uncertainty over the timing of fresh supply reaching export channels.
Arabica futures on ICE US settled higher across the curve, with the September contract briefly reclaiming the psychologically important 280.00 c/lb level before ending the session just below it. Although intraday volatility remained elevated, buyers consistently emerged on price dips, highlighting the market's willingness to maintain a supply risk premium.
The primary catalyst remains the Brazilian harvest. Fieldwork continues to lag historical averages after repeated rainfall across key producing regions slowed mechanical harvesting and post-harvest drying operations. Initial harvest progress reported by Cooxupé, the world's largest coffee cooperative, was the weakest for the period since 2022, while the latest update showed harvesting reaching just over one-fifth of the cooperative's producing area. Although progress is accelerating, it remains behind the pace normally expected for late June.
The delayed harvest has postponed the arrival of new crop coffee into commercial channels, limiting immediate export availability and reinforcing concerns over nearby supply. Market participants continue to note that even once harvesting accelerates, additional processing and preparation will be required before meaningful export volumes become available.
Supply tightness is also reflected in exchange inventories. ICE certified Arabica stocks declined again, falling below 390,000 bags after another daily withdrawal. Inventories remain historically constrained, leaving the market vulnerable to any further disruption in physical deliveries while roasters continue rebuilding coverage.
Brazilian export data reinforce the tightening supply picture. Coffee shipments during the current crop year remain significantly below last season, reflecting lower production, historically depleted carryover inventories, and producer reluctance to sell remaining stocks after benefiting from exceptionally strong prices. Despite the reduction in export volumes, export revenues have remained broadly stable because elevated prices continue to offset lower shipments.
Meanwhile, activity in Brazil's domestic physical market remained subdued. Producers continue to market coffee cautiously, showing limited urgency to increase sales despite higher futures prices, while domestic cash values remain firm.
Weather remains a critical variable. Recent rainfall across central and southern Brazilian producing regions has delayed harvesting, while unusually cool temperatures continue to attract attention, although no widespread frost threat has yet materialized. Forecasts indicate a transition toward drier conditions over the coming days, which could improve harvesting efficiency and gradually increase new crop availability. Market participants will closely monitor whether this improvement is sufficient to ease current supply concerns.
Outside Brazil, weather conditions remain challenging in parts of Vietnam. Central producing regions continue experiencing hot, dry conditions associated with persistent low humidity and localized heat, maintaining concerns over Robusta crop development despite seasonal expectations.
Robusta futures in London outperformed Arabica, with the September contract rising more than 3%, recovering above the important US$3,600 per tonne threshold. The market continues to receive support from limited nearby availability because Asian new crop supplies have yet to reach export markets in meaningful volumes, while Brazilian Conilon production remains heavily absorbed by domestic demand. Traders increasingly believe roasters will need to secure additional physical coverage during the coming months, maintaining firm demand for nearby contracts.
From a technical perspective, momentum remains constructive. Arabica has rallied approximately 15% over the past ten trading sessions, demonstrating strong speculative participation and renewed investor confidence after successfully defending recent support levels. While profit taking remains possible following the rapid advance, the market continues to trade within a fundamentally supportive environment characterized by delayed harvest progress, historically tight inventories, restrained producer selling, and continued uncertainty surrounding the timing of new crop availability.
