Yes, the national average gas price is expected to rise again this month. As of May 10, 2026, the national average stands at $4.522 per gallon, having just completed its second consecutive week of increases, jumping 25 cents to reach $4.55 per gallon as of May 7. Consumer advocates and policy analysts tracking fuel costs are warning that traders and market observers anticipate continued upward pressure throughout May 2026, driven primarily by disrupted global oil supply.
For a family driving a fuel-efficient sedan with a 14-gallon tank, the difference between current prices and last year translates to roughly $19.60 more per fill-up—a significant burden for households already grappling with inflation across food, housing, and utilities. The backdrop to this price surge is sobering: current prices have now reached their highest level since the 2022 peak of $5.01 per gallon, and they’re running $1.40 higher than this time last year. This sustained upward trajectory raises urgent questions about supply constraints, geopolitical risk, and whether government forecasts accurately anticipated the market dynamics we’re actually experiencing in May 2026.

What’s Driving Gas Prices Higher in May 2026?
The primary culprit behind the recent price increases is geopolitical disruption affecting global oil supplies. Since early March 2026, tensions have disrupted shipping traffic through the Strait of Hormuz, a critical chokepoint responsible for roughly 20 million barrels per day of oil and refined fuel products. When this vital passageway experiences interference, it creates immediate ripple effects through global commodity markets—refineries scramble to secure alternative supplies, traders bid up prices anticipating scarcity, and retail prices at the pump follow within days or weeks. This geopolitical instability is not a temporary blip; it represents sustained pressure that market analysts expect to persist through May and potentially beyond.
Domestically, U.S. gasoline inventories have fallen for 11 consecutive weeks as of May 9, 2026, tightening stockpiles ahead of peak summer driving season. Lower inventory levels mean refiners have less buffer to meet demand surges, making the market more vulnerable to any additional supply disruptions. The combination of squeezed global supplies (due to Middle East tensions) and tightening domestic stockpiles creates a two-pronged upward pressure on prices that experts warn will likely persist through the remainder of spring.
How Current Prices Compare to Recent History and Forecasts
Current prices have now climbed to levels not seen since the immediate aftermath of the 2022 energy crisis, when prices briefly hit $5.01 per gallon during the peak disruption period. The comparison is instructive: back then, the disruption was related to Russia’s invasion of Ukraine and subsequent sanctions affecting global oil supplies. Today, different geopolitical events are producing similar market consequences. The historical parallel suggests that when fundamental supply disruptions occur—whether in Eastern Europe or the Middle East—consumers should expect sustained elevated prices rather than quick relief.
More troubling for consumers is the gap between what government forecasters predicted and what has actually materialized. The U.S. Energy Information Administration (EIA) had forecast a peak near $4.30 in April 2026, but actual prices have significantly exceeded that estimate, reaching $4.55 and higher. This divergence raises important questions about whether government models adequately account for geopolitical risk factors, and whether consumers can rely on official forecasts when planning household budgets. When the gap between prediction and reality widens this dramatically, it undermines trust in the analytical frameworks policymakers and agencies use to guide economic decisions.
Inventory Declines and Summer Demand Pressure Ahead
The 11-consecutive-week decline in U.S. gasoline inventories is not an accidental phenomenon—it reflects the industry bracing for peak summer driving season. Typically, refiners build inventory in spring to prepare for increased demand in summer, when Americans take road trips, vacations, and general driving increases. That this year’s inventory building has fallen short suggests either that refiners lack confidence in their ability to source crude oil at the current prices, or that global supply constraints are so severe that normal seasonal patterns are being disrupted.
This inventory squeeze creates a structural vulnerability. If any additional supply disruption were to occur—a refinery outage, a hurricane in the Gulf of Mexico, or further middle east instability—the market would have minimal buffer stock to absorb the shock. Prices would likely spike sharply upward rather than being gradually absorbed by inventory drawdowns. For consumers, this means the risk of sudden, unexpected price jumps remains elevated through the summer months.
What Rising Gas Prices Mean for Consumer Households and Businesses
For the average household, the impact is direct and measurable. At $4.55 per gallon versus $3.15 last May, every fill-up costs substantially more. A household spending $150 monthly on gasoline last May now spends approximately $217—a $67 monthly increase that strains budgets already stressed by higher food and housing costs. For delivery drivers, long-haul truckers, and service-based businesses, fuel costs are a line item that directly affects profitability.
Smaller businesses operating on thin margins cannot always pass these costs to customers, making fuel price increases a direct hit to the bottom line. The comparison to 2022 is particularly sobering. Americans have become accustomed to prices in the $3-$4 range over the past couple of years. That means the generational experience of $4.50+ prices—last seen in 2022—feels like a shock to the system even though it’s not unprecedented. However, it does represent a meaningful erosion in purchasing power, particularly for working families with fixed incomes who have no ability to adjust their transportation budgets.
Why Government Forecasts Missed the Mark
The EIA’s April forecast of a $4.30 peak turned out to be significantly underestimated. Understanding why matters for both consumers and policymakers. The EIA models incorporate historical data, seasonal patterns, and known supply constraints, but they may give insufficient weight to sudden geopolitical disruptions or to how financial markets price in tail-risk scenarios. When traders react to Strait of Hormuz tensions, they don’t just adjust for current supply loss—they adjust for the possibility of future, more severe disruptions.
This forward-looking risk premium gets embedded in crude oil prices, which translates to higher retail gas prices. A critical limitation of government forecasts is that they’re updated periodically but markets move daily. By the time the EIA publishes a revised forecast reflecting new geopolitical information, prices have often already moved beyond that estimate. This creates a persistent gap where official guidance lags market reality. For consumers attempting to plan household finances or businesses attempting to forecast operating costs, this gap means relying on government forecasts alone could leave you unprepared for actual price levels.
Geopolitical Risk and Global Energy Markets
The Strait of Hormuz disruption affecting 20 million barrels per day represents approximately 20% of global crude oil supply. This is not a minor logistical issue—it’s a fundamental constraint on available global energy. When one-fifth of the world’s crude oil supply faces transit uncertainty, commodity markets respond with sustained price elevation. This isn’t speculation; it’s a reflection of legitimate supply risk.
The distinction matters for policy and consumer understanding. Gas prices aren’t rising because of wild speculation divorced from reality; they’re rising because actual, measurable supply constraints exist. That means price relief requires either resolution of the geopolitical tensions (reducing supply uncertainty) or discovery of new supply sources to replace disrupted flows. Until one of those conditions materializes, sustained elevated prices remain the most likely scenario.
What to Expect for Gas Prices Through Summer 2026
Based on current inventory levels, geopolitical outlooks, and seasonal demand patterns, traders and energy analysts anticipate higher gas prices could continue through May and into summer. The inventory draw-down is likely to accelerate as warmer weather drives increased driving. If geopolitical tensions in the Middle East remain unresolved, or if any new disruptions occur, the market will lack the inventory buffer that normally provides price stability.
The forward-looking risk is that current prices in the high $4 range could edge toward $4.75-$5.00 range if supply constraints tighten further. Conversely, if geopolitical tensions ease unexpectedly, prices could decline. The uncertainty itself is costly for businesses and households trying to plan budgets, which is one reason many observers are urging policy solutions—whether through strategic petroleum reserve releases, refinery investment initiatives, or diplomatic efforts to stabilize Middle East shipping routes.
Conclusion
Gas prices will likely continue their upward trajectory through May 2026 and potentially beyond, driven by geopolitical disruption of global oil supplies and tightening domestic inventory levels. Current prices at $4.55 per gallon have already exceeded government forecasts, highlighting the gap between official projections and market reality. For households and businesses, this means the cost burden of transportation continues to escalate in ways that government analysts failed to anticipate.
Moving forward, consumers should prepare for sustained elevated fuel prices rather than expecting quick relief. Monitor official forecasts from the EIA, but also track real-time price data from AAA and understand the underlying drivers—geopolitical tensions and inventory constraints. This knowledge helps explain why prices remain elevated and prepares you for potential further increases if supply disruptions continue or worsen. For policy advocates and consumer protection organizations, current price levels underscore the importance of energy independence strategies and transparent communication about actual supply constraints facing the market.
