Heating Oil COT — Week of October 17, 2026

Heating Oil COT Report: Week Ended October 17, 2026

Executive summary

The Commitments of Traders (COT) report for Heating Oil (HO) as of October 17, 2026, reveals a substantial re-engagement across participants, evidenced by an open interest surge of 25,623 contracts (+10.55%) to 268,475. Managed money registered modest net buying (+647 contracts), lifting its net long stance to +12,074 contracts. However, the dominant feature of this reporting cycle was the sharp commercial repositioning: Producers and Merchants expanded gross short positions by 21,274 contracts alongside a 16,842-contract rise in gross longs, pushing their net short exposure to -85,275 contracts. This commercial hedging activity coincided with cash-settled front-month prices pushing back toward the upper end of their yearly range, closing at $4.8979/gal on October 16.

Positioning (net, extremes vs recent weeks)

Speculative and commercial positioning in HO sits well inside historical extremes established earlier in 2026:

  • Managed Money Net Position: Stood at +12,074 contracts (32,794 longs vs. 20,720 shorts). While net long, this remains well below the 2026 peak of +24,377 contracts set on February 6, and below the early autumn peak of +20,344 on September 4. It is, however, far above the net-short regime seen in mid-January 2026 (-5,460 contracts on January 16).
  • Producer/Merchant Net Position: Recorded at -85,275 contracts (60,668 longs vs. 145,943 shorts). This reflects moderate commercial net-short hedging relative to the deep net shorts observed during January and February 2026, which exceeded -110,000 contracts (e.g., -112,090 on January 30).
  • Swap Dealer Net Position: Net long +51,995 contracts (59,355 longs vs. 7,360 shorts), maintaining steady positive exposure after bottoming near +34,849 contracts in late May 2026.

Flows and week-over-week changes

The weekly net flows across major trader categories showed modest speculative adjustments but violent two-way commercial balance sheet expansions:

  • Managed Money:
    • Gross Longs: 32,794 (+1,145)
    • Gross Shorts: 20,720 (+498)
    • Spreading: 23,927 (+2,482)
    • Net Flow: +647 contracts to +12,074. Speculators displayed balanced additions, with an emphasis on inter-month spread structures.
  • Producer/Merchant:
    • Gross Longs: 60,668 (+16,842)
    • Gross Shorts: 145,943 (+21,274)
    • Net Flow: -4,432 contracts to -85,275. Gross short hedging increased markedly as producers capitalized on prices approaching $5.00/gal.
  • Swap Dealers:
    • Gross Longs: 59,355 (+1,709)
    • Gross Shorts: 7,360 (+801)
    • Spreading: 8,688 (-627)
    • Net Flow: +908 contracts to +51,995.
  • Other Reportables & Nonreportables:
    • Other Reportables moved from net short -432 contracts to net long +2,679 contracts (+3,111 net flow), driven by +2,076 longs and -1,035 shorts.
    • Nonreportables (retail/small traders) slipped net -234 contracts to +18,527 (51,537 longs vs. 33,010 shorts).

Commercials vs speculators

The divergence between commercial hedgers and speculative money managers remains structurally defined:

Category             Gross Long   Gross Short   Net Position   WoW Net Change
Producer/Merchant        60,668       145,943        -85,275           -4,432
Swap Dealers             59,355         7,360        +51,995             +908
Managed Money            32,794        20,720        +12,074             +647
Other Reportables         9,691         7,012         +2,679           +3,111
Nonreportable            51,537        33,010        +18,527             -234
  • Commercial entities (Producers/Merchants) account for 54.4% of total short open interest and 22.6% of long open interest. Their willingness to expand short exposure by 21,274 contracts highlights strong physical producer hedging resistance at elevated price levels.
  • Managed Money holds a modest 12.2% share of total open interest on the long side and 7.7% on the short side. Speculative participation has not aggressively chased the late-summer and early-autumn price advances to new gross-long peaks, preferring to maintain moderate net-long positions with sizable spreading positions (8.9% of OI).

Open interest and participation

Total market participation rebounded sharply during the week:

  • Aggregate Open Interest: Rose by 25,623 contracts to 268,475. This represents a solid rebound from the autumn trough of 238,533 on October 2, though it remains significantly below the winter highs above 380,000 contracts seen in January 2026.
  • Trader Counts: Total reporting traders stood at 167 (down from 169 in the previous week and well below the 200+ traders recorded early in the year). Managed money accounted for 34 long traders, 13 short traders, and 27 spreading traders.
  • Concentration: The 4 largest traders held 12.0% of net longs and 13.5% of net shorts; the 8 largest traders controlled 17.1% of net longs and 19.8% of net shorts. On a gross basis, the top 8 traders held 22.4% of longs and 29.4% of shorts, pointing to a relatively dispersed market structure without extreme concentration bottlenecks.

Price context (only using provided series)

The price series for the front contract displays an exceptional year-to-date bull market:

  • Long-Term Trend: From late January 2026, front-month Heating Oil traded at $2.1872/gal (January 26) before embarking on an extended multi-month advance, breaching $3.00 in late March ($3.0848 on March 23), $3.50 in mid-May ($3.5006 on May 12), and $4.00 in mid-August ($4.0227 on August 12).
  • Recent Highs: Prices peaked at $5.0003/gal on September 15, 2026, before consolidating down into the $4.50–$4.70 range during late September and early October.
  • Reporting Week Action: After closing at $4.6827 on October 9, prices rallied aggressively during the week of this report, touching $4.9645 on October 13 and $4.9215 on October 14 before finishing at $4.8979 on October 16. The +25,623 contract OI expansion occurring alongside a ~21-cent price gain confirms fresh capital inflows into the contract rather than short covering.

Risks and watchpoints

  • Producer Hedging Overhead: The injection of 21,274 fresh producer/merchant gross shorts indicates active supply-side hedging as prices approach $5.00/gal. A failure by managed money to absorb this commercial selling could cause upside momentum to stall.
  • Speculative Hesitancy: Managed money gross longs (32,794) remain subdued relative to early 2026 (when long holdings stood near 46,000–53,000 contracts). If fund managers interpret the rally toward $5.00 as overstretched, rapid long liquidation or short re-initiation could accelerate downside corrections.
  • Open Interest Follow-Through: If the recent surge in open interest stalls and contracts drop back toward early-October levels (~238,000), it would indicate that commercial liquidity needs have been satisfied, likely triggering consolidation or range-bound trading.
