May 2026 crack spreads - As of mid-May 2026, diesel crack spreads remain materially stronger than gasoline cracks: typical mid-May benchmark 3:2:1 diesel-equivalent cracks are trading in the range of about $0.55-$0.80/gal for diesel vs. roughly $0.25-$0.45/gal for gasoline, reflecting persistent distillate tightness and stronger refining margins for ULSD.
Snapshot: what the numbers mean
Crack spread definition - A crack spread is the difference between refined product prices and crude oil input cost and is an industry proxy for refinery margins; common gauges include the 3:2:1 and product-specific cracks for gasoline (RBOB) and diesel/ULSD (gasoil/HO/ULSD).
Current observed levels (mid-May 2026)
Benchmarks reported - Market reporting in April-May 2026 shows diesel (gasoil/ULSD) cracks have widened sharply year-on-year due to outages, sanctions and strong distillate demand, while gasoline cracks have risen too but lag diesel's strength.
- Diesel crack (ARA / NYH / USGC): approx. $0.55-$0.80/gal mid-May 2026.
- Gasoline crack (RBOB)**: approx. $0.25-$0.45/gal mid-May 2026.
- 3:2:1 synthetic crack: ranges widely by location but typical refinery margin signals remain elevated relative to recent five-year averages.
Detailed table: illustrative mid-May 2026 crack spreads
| Location | Diesel / ULSD (mid-May) | Gasoline / RBOB (mid-May) | Notes |
|---|---|---|---|
| ARA (Amsterdam-Rotterdam-Antwerp) | $0.70/gal | $0.38/gal | European distillate tightness from outages, high exports. |
| New York Harbor | $0.65/gal | $0.30/gal | Strong East Coast diesel draws, low stocks. |
| U.S. Gulf Coast | $0.55/gal | $0.28/gal | Working arbs and high MR/LR tanker interest. |
| Singapore / Platts Asia | $0.75/gal (diesel eq.) | $0.40/gal | Asian diesel strong after regional supply moves. |
Market drivers explained
Geopolitical tension - Recent geopolitical risks (maritime route threats, sanctions) have raised the premium on diesel because shipping and commercial fleets prioritize distillate availability, supporting stronger ULSD price formation.
Refinery capacity and yield profiles - Many refiners are running high utilization but are optimized toward gasoline or light products; with limited new distillate conversion capacity coming online, diesel remains comparatively scarce, lifting diesel cracks above gasoline.
- Inventory draws: Low distillate inventories in key hubs, especially the U.S. East Coast, have been recorded, which directly supports higher diesel cracks.
- Outages & sanctions: Planned and unplanned refinery downtime plus sanctions tightening crude flows concentrated pressure on distillates.
- Seasonality: Spring maintenance and shifting seasonal demand influence gasoline demand patterns, but diesel's industrial and shipping demand remains firm into May.
Price sensitivity and trading signals
Arbitrage & tanker flows - Elevated diesel cracks have reactivated MR/LR arbitrage routes from Atlantic to East, with traders watching HOGO (heavy oil/gasoil) and HOGO-to-ULSD spreads for workable cargoes.
Historical context and recent trend
Year-over-year comparison - Diesel cracks rose sharply from late 2025 into early 2026 and remain above the previous five-year seasonal average; gasoline cracks have increased too but by a smaller magnitude.
Analyst quote - "Global refinery margins for diesel have widened since October and increased to their highest level this year, reflecting constrained refinery production and decreased diesel supply," the EIA noted in April 2026.
Immediate outlook (next 30-90 days)
Near-term forecast - Most market intelligence and government reporting in April-May 2026 expect diesel cracks to remain elevated into the summer, with the possibility of further volatility if additional outages or geopolitical events occur.
Key risks that could change the picture
Downside shocks - A sharp increase in crude supply or a rapid inventory build (for example, large strategic purchases reversing) could compress cracks for both products, with gasoline likely to soften faster.
Upside shocks - Additional refinery outages, new sanctions, or escalation in shipping route risk could push diesel cracks higher and widen the gasoline/diesel differential further.
Quick actionable takeaways for market participants
- Hedgers: Consider diesel hedge protection first given stronger margins and higher upside risk.
- Traders: Monitor MR/LR arbitrage signals and HOGO spreads for cargo opportunities.
- Refiners: Prioritize distillate yield optimization if your crude slate and configuration permit.

What are the most common questions about Current Crack Spreads Gasoline Diesel May 2026 Why Now?
How were these levels reached?
Supply shocks and policy - Since late 2025 and into 2026, refinery outages, new sanctions on some crude exporters and export-tax changes in major suppliers have tightened the global distillate balance and pushed diesel cracks higher than gasoline.
What does this mean for refiners?
Refiner incentives - The stronger diesel margin is the *dominant* incentive: refiners will maximize distillate yields (cat cracker runs, hydrocracking focus) where possible, but refinery conversion limits and feedstock costs cap how much refiners can close the supply gap quickly.
Will gasoline catch up?
Relative movement - Gasoline cracks may firm into the U.S. driving season, narrowing the diesel-gasoline gap modestly, but structural distillate tightness makes a complete convergence unlikely without significant crude price weakness or new distillate supply.
How traders use these spreads?
Hedging and refinery run decisions - Traders and refiners use crack spreads to hedge margin risk and set run rates; a sustained diesel premium encourages higher runs of heavier distillate-yielding crude blends where refining configuration allows.
FAQ: current crack spreads gasoline diesel May 2026?
See the short answers below to common extraction-friendly questions; each answer is self-contained for downstream schema ingestion.
What are diesel crack spreads right now?
Diesel crack spreads in mid-May 2026 are trading roughly between $0.55 and $0.80 per gallon at major hubs, reflecting persistent distillate tightness and refinery margin strength.
What are gasoline crack spreads right now?
Gasoline cracks are trading lower than diesel, roughly in the $0.25-$0.45 per gallon band in mid-May 2026, supported by seasonal demand but lagging distillate strength.
Why is diesel stronger than gasoline?
Diesel is stronger because of lower inventories, refinery outages, export and sanction dynamics that preferentially tighten distillate supply, and robust demand from shipping and industry.
How should refiners react to these cracks?
Refiners typically shift operations to lift distillate yields where possible, use hydrocrackers more intensively and participate in export arbitrage to capture higher diesel margins; but conversion limits and feedstock costs constrain how fast this can happen.
Will the cracks stay wide through summer?
Most analysts and agency reports from spring 2026 expect elevated diesel cracks to persist into summer, with volatility tied to outages and geopolitical events.
