Heating Oil Futures (NY Harbor ULSD) - COT Brief: April 17, 2026

Executive summary

This week's report reveals a significant divergence between commercial and speculative traders amid a sharp price decline. Managed Money turned more cautious, adding fresh shorts as prices fell, slightly reducing their net long stance. In stark contrast, Commercials (Producers/Merchants) aggressively reduced their net short position to the lowest level in the provided dataset, using the price weakness to buy back hedges. This opposing flow occurred as overall market participation (Open Interest) increased notably but remains well below levels seen earlier in the year. The price action confirms this dynamic, with a steep sell-off during the reporting week creating the opportunity for this positioning shift.

Positioning

• Managed Money (Speculators): Net position decreased slightly to +16,582 contracts net long (27,170 long vs. 10,588 short). This is down from +17,766 contracts the prior week and is a considerable reduction from the +24,000 level seen in February.
• Producer/Merchant (Commercials): Net position became significantly less short, moving to -66,569 contracts (55,542 long vs. 122,111 short). This is the smallest net short position for this category in the provided historical data, indicating a substantial reduction in hedging or producer selling at current price levels.
• Swap Dealers: This group remains heavily net long at +37,276 contracts, though this is a reduction from the +42,037 net long position held the prior week. They continue to act as the primary counterparty to the commercial short position.

Flows and week-over-week changes

The market saw a significant reshuffling, driven by opposing views on the recent price drop. - Managed Money: The net long position was reduced by 1,184 contracts. This was not due to long liquidation but rather a notable increase in fresh short positions (+1,751 contracts) alongside a minor addition of longs (+567 contracts). This signals a growing bearish conviction among some funds. - Producer/Merchant: This category saw the most dramatic weekly change, with their net position increasing by 5,699 contracts. The move was driven by a substantial addition of new long positions (+10,335 contracts), which far outpaced the increase in shorts (+4,636 contracts). This is a strong signal of commercial buying into weakness. - Swap Dealers: Reduced their net long exposure, primarily by liquidating 4,974 long contracts while only trimming 213 shorts.

Commercials vs speculators

The classic divergence between commercials and speculators was on full display this week. - Speculators behaved as trend-followers, adding short exposure as the price of Heating Oil fell sharply during the reporting period. While their overall position remains net long, the addition of new shorts suggests they are either protecting profits on existing longs or initiating new bearish bets. - Commercials, often considered the "smart money" with deep fundamental insight, took the opposite view. They used the price decline as a major opportunity to buy back short hedges. Their net short position is now at its most benign level in months, suggesting they see less downside risk or find current prices attractive for securing future needs.

Open interest and participation

• Total Open Interest (OI) saw a healthy increase of 14,486 contracts, rising to 243,365. An increase in OI alongside a price decline typically confirms the downtrend, suggesting new money is entering to fund short positions.
• Despite the weekly increase, overall market participation remains very low. Current OI is approximately 36% below the peak of over 381,000 contracts seen in late January. This lower liquidity environment could exacerbate price swings.
• Position concentration among the largest traders remains moderate. The top 4 largest short traders hold 15.5% of the net short position, which is in line with recent historical levels.

Price context

The positioning changes align perfectly with the price action during the reporting week (from the close of April 7th to April 14th). - The front-month contract experienced a significant sell-off, falling from a close of approximately $4.38 on April 7th to $3.6467 on April 14th, the final day of the COT reporting period. - Managed Money's addition of shorts occurred directly into this sharp price decline. - Commercials' aggressive buying and short-covering was a clear reaction to prices becoming more attractive. - Notably, after the reporting period concluded, prices rebounded slightly before falling sharply again to $3.423 on Friday, April 17th, suggesting the selling pressure observed in the report may have continued.

Risks and watchpoints

• Commercial vs. Speculator Divergence: The primary watchpoint is the stark disagreement between commercials buying and speculators selling. The resolution of this tension will likely dictate the market's next major move. While commercial buying can provide a floor, persistent speculative selling could overwhelm it in the short term.
• Weak Speculative Longs: Although the Managed Money net position is long, the increase in gross shorts indicates that the bullish conviction is cracking. These remaining long positions could be vulnerable to further liquidation if prices continue to fall.
• Commercial Floor: The fact that the commercial net short is at a multi-month low is a powerful underlying signal. Continued reduction of this short base would be a strongly bullish long-term indicator, suggesting physical market participants see value at these levels.
• Low Liquidity: The depressed level of Open Interest relative to earlier in the year remains a key risk. Thin markets can be prone to gaps and sharp, volatile moves on any surprising news flow.
