Heating Oil (NY HARBOR ULSD) - Commitments of Traders Brief: Week Ending April 24, 2026

Executive Summary

This report covers a significant divergence in positioning amid a sharp price rally. Speculators (Managed Money) turned more bearish, aggressively adding to short positions and cutting their net long exposure as prices surged. This suggests profit-taking or a view that the rally was overextended. In stark contrast, Commercials (Producer/Merchant) remain at their least-hedged (least net short) level in the provided historical data, indicating they were not aggressively selling into the price strength. Total Open Interest, while still near historical lows for this period, saw a modest increase, signaling a potential return of market participation. The key tension to watch is whether the speculative selling presages a top or if the lightly-hedged Commercials will be forced to cover in a rising market.

Positioning

• Managed Money (Speculators): Net long position fell to +13,866 contracts. This is a significant reduction from the peak net long position above +24,000 contracts seen in late March and early February, and marks the fifth consecutive week of declining net length.
• Producer/Merchant (Commercials): Net short position is now -66,269 contracts. This is the least net short this category has been across all provided data going back to December 2025. Their peak net short position was over -112,000 contracts in late January. This signals a major reduction in hedging activity.
• Swap Dealers: Increased their net long position to +38,169 contracts, primarily by reducing short exposure. They continue to hold the largest net long position among all categories.

Flows and Week-over-Week Changes

The reporting week saw a notable bearish shift from the speculative camp, which contrasts with the actions of commercials. - Managed Money: The primary driver of the positioning change. While they added a modest 725 long contracts, they aggressively added 3,441 short contracts. This resulted in a net reduction of their long exposure by 2,716 contracts. - Producer/Merchant: Exhibited relatively balanced activity, adding 1,794 long contracts and 1,494 short contracts. This slightly reduced their net short stance by 300 contracts, continuing their multi-month trend of covering hedges. - Swap Dealers: Reduced exposure on both sides, cutting 764 long contracts and a more substantial 1,657 short contracts. The larger reduction in shorts increased their net long position by 893 contracts.

Commercials vs Speculators

A clear divergence in behavior defines the current market structure: - Speculators are selling into strength: Managed Money's decision to add shorts and reduce their net long position during a strong price rally is a classic contrarian signal, indicating a belief that the market has peaked for now. - Commercials are unhedged: The Producer/Merchant category's historically low net short position is significant. This implies that physical market participants either see less downside risk, have sold forward physical supply, or are waiting for even higher prices to lock in hedges. Their lack of aggressive selling into the rally provided underlying support. This sets up a classic conflict between paper and physical market participants.

Open Interest and Participation

• Total Open Interest (OI): Increased by 3,810 contracts to a total of 247,175. While this is a small uptick, it is notable as it breaks a long-term downtrend in participation. OI has fallen dramatically from its peak of over 381,000 contracts in late January and remains near the lowest levels in the provided dataset.
• Trader Count: The total number of reportable traders stands at 153, a decrease from the 200+ levels seen earlier in the year, consistent with the lower OI.
• Concentration: The largest 4 traders control 16.1% of net short positions, while the largest 8 control 26.1%. These concentration ratios are substantial but have not seen a dramatic shift in recent weeks, suggesting stable positioning among the largest participants.

Price Context

The price series provides critical context for these positioning changes. - The COT data as of Tuesday, April 24, captures a period of significant price strength. The front-month contract rallied from a close of $3.4376 on the previous report's final day (April 17) to $3.896 on April 24. - Managed Money's net selling occurred directly into this sharp rally. This is bearish behavior, suggesting they faded the move rather than chasing it higher. - The lack of significant new short-selling from Commercials during this price surge implies they were not compelled to hedge at these levels, which removed a key source of potential selling pressure.

Risks and Watchpoints

• Spec vs. Commercial Divergence: The primary risk factor is the conflict between speculators selling the rally and commercials remaining lightly hedged. A continuation of the price rally could force commercials to hedge, while a price reversal would validate the recent speculative short-selling.
• Waning Speculative Momentum: The five-week decline in the Managed Money net long position from its peak indicates that bullish conviction from this key group is fading. This could cap further rallies unless a new catalyst emerges.
• Low Open Interest: While OI ticked up slightly, its overall low level could lead to increased volatility. A sustained rise in OI alongside price would signal new, stronger conviction entering the market, whereas a price move on falling OI would be suspect.
• Potential for Short Covering: Commercials' historically low hedge level means there is significant "dry powder" for future short-selling (hedging) if prices rise further, which could act as a ceiling for the market. Conversely, if Managed Money's newly added shorts are challenged, they could be forced to cover, adding fuel to any further upside.
