Refiners Favor Distillates as Gasoline Supply Lags Into Summer

By: Alex Hodes, Energy Analyst - KC Energy

As of mid-May 2026, U.S. fuel markets are entering demand season with an unusual imbalance between gasoline supply and refining output. Gasoline inventories are not rebuilding at the typical pace, even as consumption begins to rise, creating a disconnect in seasonal dynamics. At the same time, refiners are responding to stronger margins in alternative fuels, shifting production priorities away from gasoline. This divergence is increasing the risk of tighter supply conditions just as demand accelerates.

Alex Hodes, Director of Energy Market Strategy at StoneX, has extensive experience analyzing refining trends and fuel market dynamics across U.S. energy markets. His role tracking refinery economics and product-level supply shifts gives him direct insight into how margin signals influence output decisions during critical seasonal transitions.

Key Themes from the Discussion

  • Refiners prioritize diesel and jet fuel due to stronger crack spreads than gasoline.
  • Gasoline inventories started above seasonal averages but are now drawing down faster than expected.
  • Delayed gasoline replenishment increases the risk of tighter supply during peak summer demand.

Refining Margins Shift Output Toward Distillate Supply

Refining margins are driving a clear shift toward distillate production as U.S. refiners respond to stronger profitability signals. Alex Hodes notes that "refiners are still kind of taking advantage of the elevated refining margins on diesel and jet fuel", highlighting how margin incentives are shaping output decisions. As a result, gasoline production has taken a secondary role during the early part of the season, delaying the usual replenishment cycle. This shift is increasing the likelihood of tighter gasoline supply as demand will accelerate into the summer months.

Gasoline Supply Lags as Demand Approaches Seasonal Peak

Gasoline supply is lagging behind seasonal expectations as inventory drawdowns outpace replenishment heading into peak demand. Hodes explains that "we've seen this really aggressive drawdown rate", even though inventories began the season above historical norms. This dynamic suggests that refiners may need to adjust output quickly if demand rises as expected during the driving season. In turn, delayed supply responses could amplify price volatility and increase pressure on both consumers and policymakers.

Perspective: Morning Commentary for July 2

July 2 – All eyes are on the labor market to start the day, with the Friday holiday pushing June’s Non-Farm Payrolls report up to the same day, and release time, as weekly Jobless Claims. It was a very ugly headline print for Non-Farm Payrolls with only 57k jobs added in June, effectively only half of the expected 110k. To make matters worse, both April and May were revised lower by 31k and 43k, respectively, to now show a combined 277k jobs added instead of 351k. Despite this negativity, the unemployment rate dropped to 4.2% from the 4.3% seen from March through May, representing the lowest headline unemployment reading since June of last year. However, the drop was largely a function of a collapsing labor force participation rate, falling 0.3% month-over-month to sit at only 61.5% in June, a low not seen since March 2021 during the pandemic recovery. Average hourly earnings came in as expected, up 0.3% month-on-month and 3.5% year-on-year, as did the average workweek at 34.3 hours.
