Coffee COT Report: 2026-09-11

Executive summary

A significant divergence has emerged in the Coffee futures market, with speculative and commercial participants holding diametrically opposed views. Managed Money speculators aggressively liquidated their net long position, pushing it to the lowest level seen in the provided historical data. This move signals a strong bearish sentiment among funds. In stark contrast, Producer/Merchant commercials (hedgers) drastically reduced their net short position to its least-short level in recent months, a historically bullish signal. This suggests that physical market participants see less need to hedge against falling prices. This classic battle is occurring as overall market participation, measured by open interest, falls to a multi-month low.

Positioning

• Managed Money: Speculators hold a net long position of +22,109 contracts, down sharply from +26,729 in the prior week. This is the smallest net long stance for this group in the entire historical dataset provided, which stretches back to late 2025.
• Producer/Merchant: Commercials are net short by -22,668 contracts. This is the least-short (most bullish) they have been in recent months, a significant reduction from their -35,000 contract net short position just a few weeks prior.
• Swap Dealers: This group maintains a net long position of +3,028 contracts, a slight increase from the prior week and near the upper end of their recent range.

Flows and week-over-week changes

The reporting week saw a clear rotation out of speculative longs and into commercial hands. - Managed Money: The shift in this category was decidedly bearish. Funds sold 2,950 long contracts while simultaneously adding 1,670 new short positions, for a total net selling of 4,620 contracts. - Producer/Merchant: Commercials exhibited strong buying activity. They added 2,524 long contracts and covered 3,569 short hedges, resulting in a net position change of +6,093 contracts. - Swap Dealers: This group also tilted slightly more bullish, driven by covering 1,179 short contracts against a smaller liquidation of 617 longs. - Open Interest: The total number of outstanding contracts fell by 3,139 to 152,136.

Commercials vs speculators

The current positioning reveals a classic standoff between hedgers and speculators in the KC market. - Speculators have turned decisively bearish. The multi-month trend of a large net long position (often above +30,000 contracts) has reversed sharply. The liquidation of longs and addition of new shorts suggests funds are betting on further price declines. - Commercials are sending the opposite signal. By aggressively buying back short hedges, they indicate that they perceive current price levels as less risky or potentially undervalued. This reduction in hedging is a strong vote of confidence from those closest to the physical coffee trade. This divergence is often a precursor to a market turning point, with commercials historically being better positioned at extremes.

Open interest and participation

Total open interest of 152,136 contracts is now at the lowest level in the provided data, marking a significant decline from the peak of over 213,000 contracts seen in June. This trend of falling open interest alongside speculative selling suggests that capital is leaving the market rather than aggressively repositioning for a new downtrend. Such an environment can sometimes signal that a move is becoming exhausted. - Concentration: The market concentration is relatively balanced. The largest four traders on the short side control 15.1% of the net position, while the top four on the long side control 13.3%. This does not suggest an overly crowded trade dominated by a few large players.

Price context

Price series data was not available for this reporting period. Therefore, we cannot directly correlate these positioning changes with recent price action. However, a significant liquidation of speculative longs coupled with aggressive short-covering from commercials typically occurs during a period of price weakness. The commercial activity would suggest they view falling prices as a buying opportunity, while speculators may be capitulating on formerly profitable long positions.

Risks and watchpoints

• Positioning Divergence: The primary factor to watch is the stark disagreement between speculators and commercials. A resolution of this divergence, where one group begins to adopt the other's positioning, will be key for determining the market's next major direction.
• Speculative Exhaustion: The managed money net long position is at a multi-month low. If this selling pressure abates, the market could be vulnerable to a sharp reversal or short squeeze, especially given the reduced level of commercial hedging.
• Open Interest: A stabilization and subsequent rise in open interest would be a critical signal that new capital is entering the market and a more sustainable trend is beginning. The current low-participation environment could lead to heightened volatility on any news catalyst.
