Gasoline RBOB Futures COT Brief: Week Ending 2026-08-21

Executive summary

Speculative sentiment in Gasoline RBOB (RB) futures grew increasingly bullish during the week ending August 21, 2026. Managed Money extended its net long position to a substantial 74,081 contracts, adding new longs as prices rallied. This was met by increased hedging from Commercials, who expanded their net short position to -90,626 contracts. The market saw a healthy influx of new positions, with Open Interest rising by 10,340 contracts, suggesting strong conviction behind the recent moves. While the speculative long position is significant, it remains below the highs seen earlier in the year, but the one-sided nature of the trade presents a key risk.

Positioning

• Managed Money: Funds hold a significant net long position of +74,081 contracts (86,610 long vs. 12,529 short). This is a strong bullish stance, approaching the highs seen in late February (+88,820 contracts). The ratio of long to short traders in this category is heavily skewed at 67 to 12.
• Producer/Merchants (Commercials): This group remains the largest net short, with a position of -90,626 contracts (79,174 long vs. 169,800 short). This reflects significant producer hedging against higher prices.
• Swap Dealers: Swap Dealers hold a net long position of +20,137 contracts (50,171 long vs. 30,034 short), taking the other side of commercial and speculative flows.

Flows and week-over-week changes

• Managed Money was the primary driver of the week's activity, increasing their net long position by 4,230 contracts. This was achieved by adding 4,378 new long contracts while adding a minimal 148 short contracts, indicating outright bullish buying.
• Producer/Merchants increased their net short position by a modest 914 contracts. They added significantly to both sides of the book, with 7,586 new longs and 8,500 new shorts, pointing to broad-based hedging activity.
• Swap Dealers became more bearish, increasing their net short exposure by 2,933 contracts. This was driven by a large addition of 4,807 short positions, far outpacing the 1,874 new longs.

Commercials vs speculators

The classic dynamic is on full display in the RBOB market. Speculators (Managed Money) are firmly positioned for higher prices, while Commercials (Producer/Merchants) are positioned for a decline or are hedging future sales. - Speculators: The net long position of +74,081 contracts represents a strong consensus view among funds. The addition of new longs this week shows they were buying into the price rally. - Commercials: The large net short position of -90,626 contracts underscores the scale of hedging by refiners and other physical market participants. Their willingness to add to short positions suggests they see current price levels as attractive for locking in future revenue.

Open interest and participation

• Total Open Interest (OI) rose by 10,340 contracts to stand at 335,534. A rising OI during a period of rising prices and increasing speculative net length is typically seen as a confirmation of the bullish trend, as it signals new money entering the market to support the move.
• Participation remains robust, with a total of 236 traders reported.
• Market concentration is moderate. The four largest traders control 13.1% of the net short positions, while the eight largest control 21.0%. This indicates that while a few large players are present, the market is not dominated by them.

Price context

The positioning changes occurred during a week of strong positive price momentum for RB futures. - The front-month contract closed at $3.1788 on Friday, August 14. - By Tuesday, August 18 (the effective date for this COT report), the price had rallied to close at $3.3072. - The rally continued through the end of the week, with the price closing at $3.3282 on Friday, August 21. - The +4,230 contract increase in the Managed Money net long position is consistent with speculators buying into this price strength.

Risks and watchpoints

• Crowded Long Trade: The Managed Money net long position is substantial. While not at a record extreme, its size makes the market vulnerable to a sharp reversal if sentiment shifts. A sell-off could be exacerbated by these funds rushing to liquidate their profitable long positions.
• Commercial Selling Pressure: The large commercial net short position could act as a headwind for prices. If the rally continues, expect commercials to increase their hedging (selling) activity, which could absorb buying pressure and cap the upside.
• Open Interest as a Guide: Monitor Open Interest in the coming weeks. If prices begin to stall or fall while OI also declines, it would signal that the bullish speculators are closing their positions and the trend may be reversing.
