Heating Oil COT Brief: Week Ending 2026-08-21

Executive summary

Speculative and intermediary buying intensified in the Heating Oil futures market this week, coinciding with a sharp price rally. Managed Money added to their net long position, primarily through new long contracts, while Swap Dealers significantly increased their already large net long exposure. This speculative buying was met by increased hedging from Producers/Merchants, who expanded their substantial net short position. Open interest rose, suggesting new capital entered the market, validating the bullish price action seen during the reporting period. The market structure shows a classic divergence, with commercials heavily net short and speculators/dealers holding the long side.

Positioning

• Managed Money: This speculative group increased their net long position to +15,883 contracts (39,534 long vs. 23,651 short). This is up from +13,574 contracts the prior week and marks a continued build in bullish sentiment over the past month, though it remains below the peak net long of over +24,000 contracts seen in February.
• Producer/Merchant (Commercials): Commercials deepened their net short position to -83,877 contracts (50,190 long vs. 134,067 short). This is a significant hedging position, though still shy of the -100,000+ levels seen earlier in the year.
• Swap Dealers: This group holds a very large net long position of +48,824 contracts (56,615 long vs. 7,791 short), up notably from the prior week. This position is approaching the highs seen in January and indicates they are a primary counterparty to commercial shorts.

Flows and week-over-week changes

The most significant flows for the week ending August 18th were: - Managed Money: The net long position grew by 2,309 contracts. This was driven by the addition of 3,242 new long contracts, offset partially by an increase of 933 short contracts. The preference for establishing fresh longs over closing shorts points to growing bullish conviction. - Producer/Merchant: Commercials added 2,296 contracts to their net short position, adding both longs (+3,176) and a larger number of shorts (+5,472), likely reflecting increased producer hedging into price strength. - Swap Dealers: This group had the most aggressive bullish flow, increasing their net long position by 4,645 contracts. This was achieved by adding a substantial 4,213 new longs while also covering 432 short positions.

Commercials vs speculators

The positioning landscape paints a clear picture of opposing views. Commercial entities, who produce or use physical heating oil, are heavily hedged against a price decline, holding a net short of -83,877 contracts. This risk is being absorbed primarily by two groups: 1. Swap Dealers, with a +48,824 contract net long, are the largest holders of long-side risk, likely acting as an intermediary for commercial hedging programs. 2. Managed Money, with a +15,883 contract net long, represents the classic speculative view that prices will rise further.

The remaining balance is held by Other Reportable and Non-Reportable (retail) traders. This dynamic is typical for a healthy futures market but highlights the tension between physical hedgers and financial players.

Open interest and participation

• Open Interest: Total open interest increased by 5,119 contracts to a total of 271,139. The rise in open interest alongside a price rally is a bullish signal, as it indicates that new money is entering the market to establish long positions, rather than the rally being fueled solely by short covering. Current OI is in the mid-range of levels seen this year.
• Concentration: The market shows a moderate level of concentration. The largest four reporting traders control 13.6% of the short side and 11.5% of the long side. For the largest eight traders, this expands to 20.6% of short positions and 17.4% of long positions. The slightly higher concentration on the short side is typical for a market with large-scale commercial producers.

Price context

The positioning changes in this report, which cover the week through Tuesday, August 18th, occurred during a period of significant price appreciation. The front-month Heating Oil contract closed at $4.2837 on Friday, August 14th, and rallied to close at $4.491 on Tuesday, August 18th. This price strength provided an incentive for producers to increase their hedges, and it clearly attracted fresh speculative buying from Managed Money and Swap Dealers, as reflected in their increased long exposure. In the days following the COT data capture (Aug 19-21), the price consolidated, closing the week at $4.4687.

Risks and watchpoints

• Speculative Length: While Managed Money has been adding to longs, their net position is not yet at a historical extreme. This suggests there is still capacity for further speculative buying if the bullish narrative holds.
• Commercial Hedging Pressure: The large and growing net short position from commercials could act as a headwind for prices. If the rally continues, expect further selling from this group, which could cap upside potential.
• Swap Dealer Unwind: The very large net long held by Swap Dealers is a key feature of the market. A sudden reversal or unwinding of this position, for any reason, would remove a major pillar of support for the market and could lead to a sharp price correction.
