Heating Oil COT Brief: Week Ending 2026-09-18

Executive summary

Speculative interest in Heating Oil futures waned significantly during the reporting week, despite a strong rally in prices. Managed Money funds reduced their net long position for the third consecutive week, cutting longs and adding new shorts into rising prices. This divergence suggests a lack of conviction in the rally's sustainability. Concurrently, Commercial producers and merchants aggressively ramped up their hedging activity, adding substantially to both long and short positions, ultimately deepening their already large net short stance. The increase in total open interest was driven by this commercial activity, not new speculative buying, signaling that producers are actively using higher prices to lock in future sales.

Positioning

• Managed Money: The net long position fell by 2,659 contracts to +12,700 contracts. This is the smallest net long held by this group in over a month and marks a significant reduction from the +20,344 contract net long held just two weeks prior.
• Producers/Merchants: The commercial net short position deepened by 1,896 contracts to -84,085 contracts. This group remains the largest net short in the market, reflecting significant producer hedging.
• Swap Dealers: This cohort increased their already substantial net long position, which now stands at +49,826 contracts. They continue to absorb the significant selling pressure from commercial hedgers.

Flows and week-over-week changes

The reporting week saw a notable increase in market participation, with total Open Interest rising by 11,950 contracts.

• Managed Money was the primary seller, liquidating 1,415 long contracts while simultaneously establishing 1,244 new short positions. This two-sided bearish flow underscores their fading bullish sentiment.
• Producers/Merchants showed a massive surge in gross positioning. They added 10,453 long contracts and an even larger 12,349 short contracts. This indicates a major increase in hedging activity on both sides of the market.
• Non-reportable (small retail) traders turned more bullish, adding 2,759 long contracts and covering 828 shorts.

Commercials vs speculators

The classic positioning dynamic is in full display, with a clear divergence in views. * Commercials (Producers/Merchants) are heavily net short at -84,085 contracts. Their willingness to add over 12,000 new short hedges during the week suggests they view current price levels as attractive for selling forward. Their short positions (146,578 contracts) outweigh their long positions (62,493 contracts) by more than two-to-one. * Speculators (Managed Money) are retreating from their bullish stance. At a net long of just +12,700 contracts, their positioning is becoming more neutral. The fact they were net sellers into a strong price rally is a potential red flag for the sustainability of the uptrend.

Open interest and participation

• Open Interest: Total open interest rose to 277,030 contracts. The increase of 11,950 contracts this week is significant because it occurred alongside a reduction in the speculative net long. This suggests the new participation was primarily driven by hedgers, not new money chasing the trend higher.
• Concentration: The market shows moderate concentration. The four largest traders hold 14.7% of the net short position, while the eight largest hold 21.0%. This is slightly less concentrated than the prior week, indicating the new commercial hedging was distributed across a number of participants rather than just a few large players.

Price context

The positioning changes occurred during a week of strong upward price momentum for the front-month HO contract. * The price rallied from a close of $4.9936 on September 11th to $5.2535 on September 15th, the as-of date for this report's positions. * The fact that Managed Money traders were net sellers during this sharp rally is a significant bearish divergence. It indicates profit-taking and a potential belief that the market was becoming overbought. * Commercials behaved as expected, using the price strength to increase their short hedges at more favorable levels.

Risks and watchpoints

• Speculative Exhaustion: The key watchpoint is the divergence between rising prices and declining speculative long interest. If Managed Money continues to liquidate longs or flips to a net short position, it could remove a key pillar of support for the market and signal a price top is forming.
• Commercial Selling Pressure: The producer net short position of -84,085 contracts represents a significant wall of selling that could cap further rallies. These participants are likely to continue selling into any further price strength.
• Rising Open Interest: The increase in open interest driven by commercial hedging rather than speculative buying is a bearish signal. It indicates that "smart money" hedgers are more active than trend-following funds at these price levels.
