Gasoline RBOB COT Brief: Week Ending July 31, 2026

Executive summary

This report covers positioning in the NYMEX RBOB Gasoline futures market for the week ending July 31, 2026. Speculators, led by Managed Money, remain substantially net long, but this conviction was tested during the week as prices fell. The most significant development was a broad reduction in market participation, with open interest falling by 9,232 contracts. This decline was driven by liquidation from all major categories, including long liquidation from both speculators and commercial hedgers. While Managed Money's net position barely changed, this masks a reduction in both long and short positions, suggesting a de-risking move in a falling market rather than fresh conviction. Commercials remain heavily net short, consistent with producer hedging, but also reduced their gross exposure on both sides.

Positioning

• Managed Money (Funds): The speculative net long position stands at +73,877 contracts (86,809 longs vs. 12,932 shorts). This remains a historically elevated bullish stance but is off the peak of over +88,800 contracts seen in late February 2026. The number of shorts is extremely low, nearing the lows for the provided historical period.
• Producer/Merchant (Commercials): Commercials hold a deep net short position of -96,118 contracts (66,659 longs vs. 162,777 shorts). This is their most bearish net position in over a month and reflects significant producer hedging.
• Swap Dealers: This category holds a net long position of +23,339 contracts (47,399 longs vs. 24,060 shorts), a notable increase from the prior week.

Flows and week-over-week changes

• Managed Money: Funds registered a marginal net purchase of just 170 contracts. However, this was the result of significant gross position changes: long liquidation of 1,792 contracts was slightly outpaced by aggressive short-covering of 1,962 contracts. This indicates a reduction in overall exposure, not new bullish bets.
• Producer/Merchant: Commercials were significant sellers on a net basis, increasing their net short position by 1,959 contracts. This came from a very large reduction in long hedges (-10,847 contracts) that was larger than their reduction in short hedges (-8,888 contracts).
• Swap Dealers: Increased their net long position by 1,985 contracts, primarily achieved by reducing short positions (-1,544 contracts) while adding a smaller number of longs (+441 contracts).

Commercials vs speculators

The classic positioning dynamic is in full effect. Commercial participants (Producers/Merchants) are the market's largest net sellers, using futures to hedge physical product. Their net short position of -96,118 contracts provides the sell-side liquidity absorbed by speculators. On the other side, Managed Money provides the bulk of the speculative length (+73,877 contracts), betting on higher prices. Swap Dealers are also positioned net long, adding to the speculative imbalance against commercial shorts.

Open interest and participation

• Open Interest: Total open interest fell sharply by 9,232 contracts to a total of 321,258. This is the lowest level of market participation since early May 2026. A decline in open interest during a period of falling prices often signals that long-holders are liquidating positions, confirming the downtrend's strength.
• Concentration: The largest traders continue to dominate the short side more than the long side. The top 8 traders by net position account for 20.7% of the total short interest, compared to 15.3% of the long interest. This indicates a relatively concentrated group of large commercial hedgers.

Price context

The positioning changes occurred in a bearish price environment. The front-month RBOB contract closed at $3.2180/gallon on the report's "as of" date of July 31. This was a significant drop from the prior week's close of $3.4214 (July 24). The price decline appears to have been the catalyst for the broad-based long liquidation seen across both speculative and commercial categories. The fact that Managed Money covered shorts but also sold longs into the decline suggests a lack of appetite to "buy the dip."

Risks and watchpoints

• Vulnerable Speculative Length: The large net long position held by Managed Money remains a key vulnerability. With prices falling, these positions are under pressure, and further long liquidation could accelerate a move lower.
• Lack of Shorts: Managed Money's outright short position is minimal at just 12,932 contracts. This removes a key source of potential buying power, as there is little fuel for a powerful short-covering rally. The primary risk is an unwind of the crowded long side.
• Falling Open Interest: The sharp drop in open interest is a bearish signal. A continuation of this trend would confirm that capital is leaving the market. A reversal, where open interest begins to rise again alongside price, would be needed to signal a potential bottoming process.
