Arabica Tumbles as Technical Breakdown and Cecafé Data Disruption Unsettle the Market (27 August 2026)

Arabica coffee futures suffered another sharp decline on Thursday as a break below key chart levels intensified selling and an abrupt change in Brazilian export statistics added to an already volatile market.

The New York December contract lost 12.50 cents, or 3.88%, to settle at 309.65 cents per pound. Prices traded across a 10.60-cent range and touched 306.45 cents, their lowest point since early August. The September contract fell even more sharply, declining 15.70 cents, or 4.4%, to 341.90 cents.

Market participation increased substantially. New York volume reached 38,148 lots, up 12,565 lots from Wednesday, indicating that the decline was accompanied by aggressive liquidation rather than occurring in thin trading conditions.

Technical selling accelerates

December Arabica broke below support at 316.95 and 311.75 cents during the session, reinforcing the deterioration in short-term momentum. The contract has now lost 32 cents, or approximately 9.4%, over three trading days.

The scale of recent fluctuations illustrates how unstable the market has become. During the first four sessions of the week, December futures moved through a 39.50-cent range, from a high of 345.95 cents to Thursday’s low of 306.45 cents.

The average daily range reached 15.31 cents, marginally above the previous week’s 15.15 cents. Over the latest 10 sessions, daily volatility has averaged 15.23 cents. Such persistent price swings suggest that short-term positioning, stop-loss orders and rapidly changing headlines are exerting an unusually strong influence over price formation.

While the longer-term upward trend has not been completely overturned, the loss of technical support leaves the immediate outlook vulnerable. At the same time, the speed of the decline has pushed the market into deeply oversold territory, increasing the possibility of an abrupt corrective rebound.

Arabica spreads lose part of their premium

Calendar spreads also weakened as some of the market’s immediate scarcity premium was removed.

The December–March spread narrowed to 11.35 cents from 14.05 cents, while December–May declined to 14.75 cents from 18.50 cents. March–May eased to 3.40 cents from 4.45 cents.

Although the structure continues to reflect tight nearby availability, the compression indicates that pressure was concentrated in the front portion of the Arabica curve.

Certified inventories, however, remain exceptionally low. Exchange stocks decreased by another 606 bags to 224,011 bags. During the latest certification activity, 1,280 bags were rejected, 320 bags were approved and 640 bags remained pending.

For comparison, certified stocks stood at 717,113 bags at the same point last year. The continuing decline towards levels not seen in more than two decades remains an important source of underlying support, despite the present weakness in futures.

Robusta follows New York lower

London Robusta also declined, although less aggressively than Arabica. The November contract lost $59 per tonne, or 1.63%, to close at $3,555. Prices moved between $3,514 and $3,588, breaking below the first technical support level around $3,562.

London volume increased to 27,155 lots, 2,840 more than in the previous session.

Robusta spreads softened alongside the outright market. November–January narrowed to $14 per tonne from $16, November–March fell to $33 from $40, and January–March slipped to $23 from $24.

With New York underperforming London, the Arabica–Robusta price differential contracted to 148.40 cents per pound from 158.25 cents one session earlier.

Sudden export revision adds to selling pressure

The sell-off coincided with an abrupt change in the Brazilian export figures published through Cecafé’s system.

As of August 24, the platform showed monthly shipments of 1,707,729 bags, down 9.3%, with a daily average of 71,155 bags. The total included approximately 1.046 million bags of Arabica, 499,501 bags of Robusta and 162,280 bags of soluble coffee.

Certificate-of-origin requests stood at 1,826,378 bags, down 20.9%, and the available pace suggested that August exports would finish near 2.42 million bags.

No figures were released on August 25. When the information was updated on August 26, recorded shipments had jumped by more than 1.23 million bags to 2,940,606 bags. The implied monthly projection consequently increased to approximately 3.85 million bags.

By August 27, the system showed shipments of 3,197,635 bags, an increase of 27.8%, with the daily average rising to 118,430 bags. The reported composition included roughly 2.226 million bags of Arabica, 734,000 bags of Robusta and 233,000 bags of soluble coffee.

Requests for certificates of origin reached 3,334,659 bags, 15.7% above the comparable level. These included approximately 2.295 million bags of Arabica, 750,000 bags of Robusta and 292,000 bags of soluble coffee. Based on the updated pace, the projection for total August shipments moved above four million bags.

For a market already trading nervously, the apparent shift from a 2.42-million-bag projection to more than four million bags represented a major change in the perceived availability of Brazilian coffee. The adjustment may therefore have contributed to the activation of sell stops and the rapid deterioration in prices.

Cecafé explains system problem

Cecafé subsequently reported that an automatic update to software libraries used by its certificate-of-origin platform had temporarily disrupted certain functions of the web application and affected the connection with its database.

The problem was identified and corrected, according to the exporters’ council, which also introduced additional monitoring intended to prevent a recurrence.

The clarification does not necessarily mean that the latest cumulative export total is incorrect. However, it suggests that the dramatic increase between consecutive releases may have reflected delayed or incomplete data integration rather than a genuine one-day surge in physical shipments.

This distinction is important. The market may have interpreted the sudden arrival of previously missing information as a new acceleration in Brazilian exports, amplifying the bearish reaction at a time when technical conditions were already fragile.
