Heating Oil Futures & Options (NY HARBOR ULSD) - COT Brief for May 15, 2026

Executive summary

This week's report reveals a significant surge in market participation, with Open Interest jumping by over 19,000 contracts after a multi-month decline. This influx of activity occurred alongside a strong price rally. However, the positioning changes show a major divergence: institutional speculators (Managed Money) reduced their net long exposure, effectively selling into strength, while smaller, non-reportable traders aggressively added to their bullish bets. Commercials remain heavily net short, as expected, but their hedging posture is still lighter than the highs seen earlier in the year. The primary tension is between the cautious stance of "smart money" and the renewed enthusiasm from retail participants, set against a backdrop of rising prices.

Positioning (net, extremes vs recent weeks)

• Managed Money Net Position: Currently stands at a net long of +9,770 contracts. This is a relatively modest bullish stance and marks a significant reduction from the +20,000 to +24,000 net long levels seen during February.
• Producer/Merchant Net Position: This core commercial group holds a net short position of -66,892 contracts. While a substantial short, it remains well below the extreme short levels of over -100,000 contracts registered from late January through mid-March. This suggests producer hedging is less aggressive than it was at its peak.
• Swap Dealers Net Position: Swap Dealers are net long +35,708 contracts, acting as the primary counterparty to commercial shorts. This position is also considerably smaller than the +60,000 to +70,000 contract net long they held for much of the first quarter.
• Nonreportable Net Position: Smaller traders are significantly bullish, with a net long of +28,176 contracts, the largest net long position among all speculative categories and near the highest level in the provided data.

Flows and week-over-week changes

This was a week of major activity, with nearly every category seeing significant gross position changes.

• Managed Money: Reduced their net long position by 2,009 contracts. This was driven by a notable liquidation of long positions (-2,458 contracts) that was only partially offset by a small reduction in shorts (-449 contracts). This represents a clear bearish tilt in flows from this cohort.
• Producer/Merchant: Increased gross exposure on both sides, adding 7,218 long contracts and 8,180 short contracts. This resulted in a minor increase to their net short position (-962 contracts) and points to active hedging by commercial participants.
• Nonreportable Positions: This was the most bullish flow. Small traders piled in, adding 6,985 long contracts versus only 2,657 short contracts, increasing their net long stance by a substantial 4,328 contracts.
• Swap Dealers: Slightly reduced their net long position by 685 contracts, trimming longs (-593) while adding a marginal number of shorts (+92).

Commercials vs speculators

The classic divergence between commercial hedgers and speculators is clearly visible, with a new layer of complexity between different types of speculators.

• Commercials (Producers/Merchants) are positioned for lower or stable prices, with a massive net short of -66,892 contracts. Their short positions (129,999 contracts) are more than double their long positions (63,107 contracts).
• Speculators (Managed Money + Nonreportables) are collectively net long +37,946 contracts. However, the conviction lies entirely with the smaller, non-reportable traders. Managed Money's net long of +9,770 is dwarfed by the Nonreportable net long of +28,176. This week, the institutional money de-risked while the retail money "bought the rally."

Open interest and participation

• Open Interest (OI) saw a dramatic reversal, surging by +19,031 contracts to a total of 261,758. This is a sharp break from the consistent decline seen since OI peaked above 380,000 in late January. Such a large increase signals significant new capital entering the market.
• Trader Count: The total number of reportable traders stands at 157, which is up from recent lows but still well below the 200+ traders active during the winter months.
• Concentration: The market shows moderate concentration on the short side. The largest 8 traders control 22.6% of the net short position, compared to 15.2% of the net long position. This highlights the influence of large commercial hedgers.

Price context

The price series provides crucial context for this week's positioning shifts.

• The reporting period covers the week ending Friday, May 15, 2026.
• During this week, the front-month Heating Oil contract rallied sharply, closing at $4.06 on May 15th, up from $3.8839 at the close of the prior week (May 8th).
• The fact that Managed Money liquidated over 2,400 long contracts into this strong rally is significant. It suggests profit-taking or a belief that the rally was over-extended. Conversely, the surge in Nonreportable longs indicates smaller traders were chasing the upward price momentum.

Risks and watchpoints

• Speculative Divergence: The opposing flows between Managed Money (selling) and Nonreportables (buying) is the key watchpoint. A continued price rally would vindicate the retail crowd, but a reversal could lead to a rapid unwind of these newly established small speculator longs.
• Light Commercial Hedging: While Commercials are net short, their position is far from historical extremes. A further, sustained price rally could force them to increase their short hedging activity, which could act as a headwind for prices.
• Open Interest Sustainability: The +19k contract jump in OI is a major bullish signal for participation. Monitoring whether this trend continues is critical. If OI begins to fall again alongside rising prices, it would suggest a lack of new buying and an increased risk of a "short squeeze" conclusion. If OI continues to build, it would validate the potential for a new leg higher.
