On July 16, 2026, Reuters reported the 3-2-1 crack spread closed at $69.66 per barrel, up over 2% to a record high. The spread is described by Reuters as "the most widely used benchmark for U.S. refiner profitability." The move tracks a broader rally in gasoline pricing. CME Group's "Fresh from the Trading Room" newsletter on July 14 reported the gasoline crack spread at $43 per barrel, with RBOB gasoline up 73% year-to-date. The RBOB Gasoline continuous contract (RB00) futures price stood at $3.3910 per gallon as of July 17, per MarketWatch.

The 3-2-1 crack spread reflects gasoline and distillate production revenues from the U.S. refining industry. Per CME Group, it combines ULSD and RBOB crack spreads in a proportion that more closely matches refined product output. The EIA defines the gasoline crack spread as the difference between the RBOB New York Harbor spot price and the Dated Brent Spot price. Three barrels of crude are notionally processed into two barrels of gasoline and one barrel of distillate.

What is moving these margins. According to EIA data published July 15, petroleum markets responded to disruptions in the Middle East in the second quarter of 2026. The quarterly average gasoline crack spread was up 60% year-over-year in Q2 2026. That disruption-driven repricing of light products relative to crude carried into Q3.

The EIA's July 2026 Short-Term Energy Outlook, published July 7, estimated the gasoline crack spread would increase about 10 cents per gallon on average in Q3 2026. That estimate preceded the July 16 record close in the 3-2-1 spread, which Reuters attributed to fuel shortage concerns.

Looking at what this means for refiner economics. The compression between flat crude prices and product cracks has widened materially. The 3-2-1 spread at $69.66 per barrel means the gross processing margin for a generic barrel, assuming three crude inputs and two gasoline plus one distillate output, is at a level not previously recorded in this benchmark. The $43 per barrel gasoline crack reported by CME on July 14 is a different but related metric, isolating gasoline specifically rather than the blended 3-2-1 product yield.

The 73% year-to-date move in RBOB gasoline, as reported by CME Group, runs well ahead of the Q2 60% year-over-year crack spread increase reported by the EIA. That divergence is consistent with product prices leading crude higher in a supply-shortage repricing. The EIA's Q3 estimate of a 10-cent per gallon crack spread increase, issued July 7, is lower than the magnitude of the July 16 move in the 3-2-1 benchmark, which rose over 2% in a single session to close at a record.

For market participants, the record 3-2-1 close confirms what the EIA's Q2 data and CME's YTD figures indicated: the refining margin complex has repriced sharply higher on Middle East supply disruption risk. What is known is the data as of July 16. What is priced in is further tightness. What remains uncertain is whether Q3 crack spreads settle at the EIA's July 7 estimate or continue tracking the upward trajectory the July 16 record close implies.

CME Group published RBOB Gasoline Futures settlement data for the trade date of July 15, 2026, consistent with the pricing and margin data cited above. The EIA's October 2025 definitional note on the gasoline crack spread remains the authoritative source for how the agency constructs the metric.
