Gasoline RBOB Futures (COT) for the week ending May 15, 2026

Executive summary

Speculators took profits in a rising market this week, as a sharp price rally was met with net selling from the Managed Money category. Despite a 5.2% price increase, hedge funds reduced their net long position, suggesting the recent move was not driven by fresh speculative buying. Open interest rose significantly, indicating new capital entered the market, which was absorbed by Swap Dealers and Commercials. Producer/Merchant net short hedging remains substantial but is well below the extremes seen earlier in the year. The divergence between strong price action and speculative profit-taking is the key feature of this week's report.

Positioning

• Managed Money (Speculators): The net long position fell slightly to +62,935 contracts (68,169 long vs. 5,234 short). This level is now far from the recent peak net long of +88,820 contracts seen on February 27 and is more in line with positioning from late December 2025. The gross short position remains exceptionally low at only 5,234 contracts, indicating a strong one-sided bullish consensus among this group.
• Producer/Merchant (Commercials): Commercials hold a net short position of -79,647 contracts (111,320 long vs. 190,967 short). This is a historically significant short position, reflecting aggressive hedging by producers and merchants against a potential price decline. However, it is considerably less extreme than the -118,381 contract net short seen in late February.
• Swap Dealers: This category increased its net long position to +9,231 contracts (38,123 long vs. 28,892 short), stepping in to absorb some of the selling pressure from other participants.

Flows and week-over-week changes

• Managed Money: This group was a net seller of 2,768 contracts. The move was composed of a reduction in long positions (-3,833 contracts) and a minor covering of short positions (-1,065 contracts). This activity is characteristic of profit-taking into strength.
• Producer/Merchant: Commercials were active on both sides of the market, adding significant gross positions. They increased longs by 10,112 contracts and shorts by 9,742 contracts, resulting in a marginal increase to their net short position of just 370 contracts.
• Swap Dealers: Were notable net buyers, increasing their net long position by 2,596 contracts. This was driven almost entirely by new long positions (+2,662 contracts).
• Non-reportable (Retail): Small speculators added to their bullish view, increasing their net long position by 1,402 contracts.

Commercials vs speculators

The classic market structure persists: speculators are heavily net long while commercial hedgers are heavily net short. The primary tension this week comes from the diverging actions between these two groups amid a strong price rally. While speculators lightened their bullish exposure, commercials largely maintained their hedging posture, indicating they see current price levels as attractive for locking in forward sales. This dynamic suggests a battle between momentum-driven speculative profit-taking and fundamental hedging interests.

Open interest and participation

• Open Interest: Total open interest saw a robust increase of 15,592 contracts, rising to 327,707. This influx of new positions during a price rally is a bullish sign, confirming that new capital is entering the market and validating the upward price trend.
• Participation Context: Despite the weekly increase, overall market participation is significantly lower than the peaks observed earlier in the year (e.g., 469,165 contracts on February 6). This suggests the market is less crowded than it was, potentially leaving more room for trends to develop.
• Concentration: The market shows moderate concentration on the short side. The largest 4 traders hold 13.7% of net short positions, and the largest 8 hold 21.6%.

Price context

The positioning data corresponds to a period of significant price strength. For the reporting week running from the close of May 8 to May 15, the front-month RBOB futures contract rallied from 3.521 to 3.705, an increase of approximately 5.2%. The fact that Managed Money was a net seller during this strong upward move is a notable divergence. It implies that the rally was not fueled by new speculative longs but rather by commercial activity, swap dealer buying, and potentially physical market tightness.

Risks and watchpoints

• Speculative Divergence: The primary watchpoint is the continued divergence between rising prices and net selling from Managed Money. If prices continue to climb without renewed speculative buying, it may point to a more durable, fundamentally-driven rally. A reversal in spec flows back to buying could accelerate the uptrend.
• Risk of Long Liquidation: With Managed Money gross shorts at near-historical lows (5,234 contracts), there is very little "fuel" for a short-squeeze. The dominant risk is a long liquidation event, where a break in the bullish narrative could trigger a cascade of selling from the large speculative long base.
• Open Interest Trend: A continued increase in open interest alongside rising prices would be a strong confirmation of the bullish trend. Conversely, if prices begin to fall on rising open interest, it would signal that new short positions are entering the market and building conviction.
