Gas Prices A Year Ago Today Vs LNG Now Shocking
One year ago today (May 30, 2025), the U.S. national average for regular gasoline was **$3.162 per gallon**, according to AAA fuel price data. This stands in stark contrast to the current average of $4.356 per gallon as of May 30, 2026-a year-over-year increase of **$1.194 (37.8%)**. The gas price surge coincided with a pivotal shift in global LNG markets, where record U.S. exports and inventory pressure drove natural gas futures toward $4.50/MMBtu by 2026.
Gas Price Comparison: Year Ago vs. Today
| Fuel Grade | May 30, 2025 | May 30, 2026 | Year-Over-Year Change |
|---|---|---|---|
| Regular | $3.162 | $4.356 | +$1.194 (+37.8%) |
| Mid-Grade | $3.651 | $4.864 | +$1.213 (+33.2%) |
| Premium | $4.008 | $5.237 | +$1.229 (+30.7%) |
| Diesel | $3.537 | $5.492 | +$1.955 (+55.3%) |
| E85 | $2.572 | $3.453 | +$0.881 (+34.3%) |
LNG Market Dynamics Driving the Price Shift
The natural gas market remained highly volatile throughout 2025, with converging domestic and global factors pushing prices upward. The EIA projected Henry Hub prices to average $4.20/MMBtu in 2025, rising toward $4.50/MMBtu by 2026 as demand exploded from AI data centers and LNG exports hit record levels.
Record U.S. LNG exports became a critical factor in the gas price surge, as increasingly tight global supply chains reduced domestic availability. Infrastructure and cost constraints further limited the ability to meet surging demand, creating sustained upward pressure on wholesale natural gas prices that ultimately flowed through to retail gasoline and diesel.
Key Market Indicators from May 2025
- Henry Hub natural gas futures: Averaged approximately $3.80-$4.20/MMBtu in May 2025
- U.S. LNG export volumes: Reached record highs, diverting supply from domestic markets
- Inventory levels: Entered pressure zones as demand outpaced supply growth
- Refinery operating costs: Increased due to higher natural gas input prices
- Retail gasoline trend: Started summer 2025 at $3.162/gallon, significantly below 2026 levels
Forward contract structuring and pricing mitigation strategies became critical for energy buyers as ERCOT projected peak shortfalls as early as 2026. The LNG market shift fundamentally altered the cost structure for transportation fuels across the United States.
Regional Natural Gas Price Variations (May 2025)
| Effective Date | Core Procurement Gas Price (cents/therm) | Market Context |
|---|---|---|
| May 1, 2025 | 28.265 | Spring low before summer demand spike |
| June 1, 2025 | 33.513 | Early summer demand increase |
| July 1, 2025 | 40.140 | Peak summer pricing period |
| August 1, 2025 | 40.874 | Sustained high demand |
The boardroom-grade market intelligence view confirms that May 2025 represented a inflection point where LNG export growth began materially impacting domestic fuel costs. Executives and procurement teams monitoring the global LNG value chain recognized this transition as a structural shift rather than temporary volatility.

Key concerns and solutions for Gas Prices A Year Ago Today Vs Lng Now Shocking
What caused gas prices to rise 37.8% year-over-year?
The primary drivers were record U.S. LNG exports, exploding demand from AI data centers, inventory pressure, and infrastructure constraints that limited supply response.
What was the diesel price a year ago today?
Diesel averaged $3.537 per gallon on May 30, 2025, compared to $5.492 today-a 55.3% increase, the largest among all fuel grades.
How do LNG prices relate to gasoline prices?
LNG and natural gas prices influence gasoline through crude oil linkage and refinery economics; higher natural gas costs increase refinery operating expenses and transportation fuel production costs.
Will gas prices continue rising in 2026?
Yes-EIA projections indicate Henry Hub prices will average $4.20/MMBtu in 2025 and rise toward $4.50/MMBtu by 2026 due to sustained LNG export growth and data center demand.
What companies shape the LNG market?
Leading companies include major LNG exporters, regasification technology providers, and infrastructure operators across the global LNG value chain that determine supply capacity and pricing dynamics.
