Heating Oil (NY HARBOR ULSD) COT Brief: Week Ending 2026-06-12

Executive summary

This week's report reveals a significant divergence between speculators and commercial participants in the Heating Oil market. Managed Money aggressively added to short positions, flipping their activity to a bearish stance, which aligned with the price decline seen during the reporting week. In sharp contrast, Producer/Merchant participants were strong buyers, significantly adding to long positions and reducing their net-short exposure to one of the lowest levels seen in over six months. This tug-of-war occurred amid a rise in open interest, indicating that new capital is entering the market on both sides of the trade, potentially setting the stage for increased volatility.

Positioning

• Managed Money (Speculators): The net long position for this group shrank considerably to +9,507 contracts, down from +11,997 in the prior week. This is a significant step back from the +24,377 net long peak seen in early February and marks a clear bearish turn in sentiment.
• Producer/Merchant (Commercials): This cohort's net short position contracted significantly to -63,726 contracts, compared to -67,843 last week. This is one of the least net-short positions for commercials in the provided data, which dates back to December 2025, and is substantially smaller than the peak hedge of -112,090 contracts in late January.
• Swap Dealers: This group remains the primary counterparty to commercial shorts, holding a substantial net long of +37,385 contracts, a slight increase from the prior week.

Flows and week-over-week changes

The story this week is in the flows, which highlight the market's conflicting views: - Managed Money was a net seller of 2,490 contracts. This move was decisively bearish, driven by the addition of 2,345 new short contracts, while long positions were trimmed by a minor 145 contracts. - Producer/Merchants were net buyers of 4,117 contracts. Their activity was driven by a substantial increase in long positions (+7,133 contracts), which far outpaced the addition of new short hedges (+3,016 contracts). - Non-reportable (Retail) positions also showed a bearish tilt, with a net change that saw short positions increase more than longs.

Commercials vs speculators

The current positioning highlights a classic battle between hedgers and speculators: - Speculators (Managed Money) are interpreting recent market action bearishly, adding fresh shorts as prices weakened during the reporting period. - Commercials (Producers) are acting as strong buyers on the dip. Their significant reduction in net-short exposure suggests either a belief that prices are at a value level or a decreased need to hedge forward sales, both of which are constructive signals for the physical market. This divergence is a key feature of the current landscape.

Open interest and participation

• Open Interest: Total open interest rose by 5,185 contracts to a total of 254,634. The increase in open interest alongside a price decline confirms that the move was driven by new selling (primarily from Managed Money) rather than long liquidation. It also confirms that the Producer buying was from new capital, not just short-covering.
• Participation: The market consists of 162 total reporting traders, a slight decrease from 164 last week. The number of Managed Money short traders held steady at 11, while Producer long participants decreased from 49 to 46, indicating the increase in their long position was driven by existing players adding size.
• Concentration: Position concentration among the largest traders remains moderate and stable. The largest four traders account for 13.1% of the net short position, and the largest eight account for 22.8%.

Price context

The positioning changes occurred during a week of price weakness. The front-month contract closed at 3.6055 on Friday, June 5th, and fell to 3.5496 by the close of business on Tuesday, June 9th, the effective date of this report. The aggressive short-selling from Managed Money was in line with this price decline, while Producers took the other side, using the lower prices as a buying opportunity.

Risks and watchpoints

• Speculator vs. Commercial Divergence: The primary watchpoint is the stark disagreement between speculators and commercials. If commercial buying persists, the newly established Managed Money short positions (+2,345 contracts) are vulnerable to a squeeze.
• Producer Hedging: Producers are now at one of their least-hedged levels in months. While this is currently supportive of price, a sudden need to re-establish short hedges could introduce significant selling pressure into the market.
• Open Interest Trend: The influx of new positions is a healthy sign of market engagement. A continuation of rising open interest will add "fuel" to the next directional move, amplifying its potential magnitude. The key question is whether new money will follow the speculative sellers or the commercial buyers.
