Gasoline RBOB COT Report for 2026-09-11

Executive summary

Speculators have extended their bullish stance in Gasoline RBOB futures, with Managed Money net-long positioning reaching its highest level in over a year. This aggressive buying occurred during a week of sharply rising prices, confirming speculative participation in the ongoing rally. Commercial hedgers, or Producer/Merchants, remain heavily net-short, providing the liquidity for the speculative bid and viewing current prices as an opportune level to hedge. The market saw a healthy increase in open interest, suggesting new capital flowed in to support the uptrend. However, the extreme level of speculative longs presents a significant risk of a sharp correction should the bullish sentiment falter.

Positioning

• Managed Money: This speculative cohort is now net long by a substantial +92,848 contracts, their most bullish position in the provided historical data. This is comprised of 106,371 long contracts versus only 13,523 short contracts.
• Producer/Merchants (Commercials): Commercial participants hold a large net short position of -102,029 contracts (94,208 longs vs. 196,237 shorts). While this is a significant hedge, it remains below the peak net-short level of over -114,000 contracts seen in February.
• Swap Dealers: This group holds a net long position of +14,603 contracts, acting as intermediaries in the market.

Flows and week-over-week changes

The reporting week saw a clear divergence in activity between speculator and hedging groups. - Managed Money increased their net long position by 3,633 contracts. This was a definitively bullish move, composed of adding 2,929 new long contracts while simultaneously covering 704 short positions. - Producer/Merchants modestly increased their net short position by 1,060 contracts. They were active on both sides, adding 8,459 long contracts but adding an even larger 9,519 short contracts, indicating increased hedging activity. - Swap Dealers shifted more bearish, reducing their net long exposure by 3,829 contracts. This was driven almost entirely by adding 3,579 new short positions.

Commercials vs speculators

The classic positioning dynamic is on full display and approaching an extreme. - Speculators (Managed Money) are positioned for further price increases, with their net long position at a multi-month high. Their long positions outnumber their shorts by a ratio of nearly 8-to-1. - Commercials are positioned oppositely, holding a large net short hedge. Their short positions outnumber their longs by more than 2-to-1. - This structure is typical of a trending market, with speculators driving the trend and commercials taking the other side. The stretched nature of the speculative positioning, however, suggests the trend may be mature.

Open interest and participation

• Open Interest: Total open interest grew by a healthy 11,152 contracts to a total of 365,028. This increase alongside rising prices is a constructive signal, suggesting new capital is entering the market and validating the recent price move.
• Participation: The market consists of 233 total reporting traders. Managed Money longs are held by 68 traders, while the much smaller short book is held by just 10.
• Concentration: The short side of the market is more concentrated. The largest four traders hold 15.8% of the total short interest, compared to just 9.5% on the long side. This often reflects the presence of a few large commercial hedgers.

Price context

The positioning changes occurred in a bullish price environment. - The front-month Gasoline RBOB contract rallied significantly during the reporting week, climbing from a close of $3.1998 on September 4th to $3.3305 on September 11th. - The move by Managed Money to add longs and cover shorts aligns perfectly with this price appreciation, indicating they were either chasing the rally or helping to fuel it. - This week's gains are an extension of a strong uptrend that has been in place since late July, a period during which speculative net length has consistently grown.

Risks and watchpoints

• Crowded Speculative Longs: The primary risk factor is the historically elevated net long position held by Managed Money. This one-sided positioning makes the market vulnerable to a sharp sell-off if the bullish narrative shifts, as a large number of participants would be heading for the exits simultaneously.
• Commercial Supply: The substantial net short position held by commercials represents a significant source of potential supply. These hedgers are likely to continue selling into strength, which could cap the rally's upside potential.
• Momentum Signal: The combination of rising prices and rising open interest is a sign of a healthy trend. A key watchpoint will be if open interest begins to decline even as prices attempt to push higher, which would be a warning sign of trend exhaustion.
