Gasoline RBOB Futures Positioning Brief: Week Ending 2026-08-28

Executive summary

Speculators aggressively increased their bullish bets on Gasoline RBOB futures this week, even as prices consolidated. Managed Money added significantly to their net long position, pushing it to a multi-month high. This buying was met with heavy selling and hedging from the commercial sector, whose net short position also expanded to a multi-month peak. The increase in open interest alongside the new speculative buying suggests fresh capital is entering the market on the long side. This positioning preceded a sharp price rally late in the week, indicating the speculative buying was well-timed. The market is now characterized by a classic standoff between bullish speculators and well-hedged commercial entities.

Positioning

• Managed Money Net Position: Speculators expanded their net long position to +79,652 contracts, a significant increase from +74,081 contracts the prior week and the highest level seen since late February.
• Producer/Merchant Net Position: Commercials deepened their net short position to -95,522 contracts, from -90,626 contracts previously. This represents a substantial increase in hedging activity and is the largest net short held by this group in several months.
• Swap Dealer Net Position: Swap Dealers reduced their net long position to +16,313 contracts, down from +20,137 last week, indicating a decrease in their exposure as intermediaries.

Flows and week-over-week changes

This report, which reflects positioning as of Tuesday, August 25th, was dominated by new speculative buying.

• Managed Money: This cohort was the primary driver of the week's activity, adding 6,107 new long contracts while adding only 536 short contracts. This resulted in a net buying of 5,571 contracts.
• Producer/Merchant: Commercials were active on both sides but leaned heavily short. They added 7,096 long positions but simultaneously added a more substantial 11,992 short positions, increasing their net short exposure by 4,896 contracts.
• Swap Dealers: This group shifted more bearishly, cutting 265 longs while adding 3,559 short contracts.
• Non-reportable (Retail): Small speculators were sellers, with changes resulting in a net short increase of 2,405 contracts.

Commercials vs speculators

The divergence between the market's largest participants grew wider this week, highlighting a clear difference in outlook.

• Speculators: The Managed Money net long position of +79,652 contracts signals strong conviction in higher prices ahead. They now hold 26.8% of all long positions in the market, compared to just 3.8% of the short side.
• Commercials: The Producer/Merchant net short of -95,522 contracts demonstrates significant producer hedging and/or end-user selling. This group holds 52.5% of the total short-side open interest, acting as the primary counterparty to the speculative length. This heavy commercial short position could provide a ceiling for prices if speculative buying wanes.

Open interest and participation

• Open Interest: Total open interest rose by 10,600 contracts to 346,134. A rise in open interest during a period of strong speculative buying is a bullish technical signal, suggesting that new money is fuelling the move rather than just short-covering.
• Concentration: Position concentration among the largest traders remains significant. The largest 8 traders now account for 21.9% of the net short positions (up from 21.0% last week), indicating that a small number of large commercial entities are driving the hedging activity.

Price context

The positioning data in this report is as of the close on Tuesday, August 25th. During the reporting week (from August 21st to August 25th), the front-month RB contract actually saw prices decline from approximately $3.32 to $3.22. The fact that Managed Money was aggressively adding new long positions during this price dip suggests they were "buying the dip" in anticipation of a move higher. Their conviction was rewarded in the days immediately following the reporting period, as prices surged to close the week at $3.4776 on Friday, August 28th.

Risks and watchpoints

• Crowded Trade Risk: The Managed Money net long position is now at a multi-month high. While this reflects strong bullish momentum, it also elevates the risk of a sharp correction if the fundamental or technical picture deteriorates, as it would trigger a cascade of long liquidation.
• Commercial Hedging Pressure: The substantial and growing net short position held by commercial entities represents a significant wall of supply. These hedgers are likely to continue selling into any further price rallies, which could absorb buying pressure and cap the market's upside potential.
• Follow-Through Buying: The key watchpoint for next week's report will be to see if speculators continued to add to their longs during the strong price rally from Wednesday to Friday. Continued buying on rising open interest would confirm the strength of the trend, whereas a decline in open interest could suggest the rally is becoming exhausted.
