Gas Prices Today: May 17 National Fuel Update

As of May 10, 2026, the national average gas price stands at $4.55 per gallon for regular unleaded fuel, according to AAA data released on May 7.

As of May 10, 2026, the national average gas price stands at $4.55 per gallon for regular unleaded fuel, according to AAA data released on May 7. This represents a significant spike—prices have increased 25 cents for the second consecutive week, and consumers are paying $1.40 more per gallon than they were a year ago in May 2025. The May 17 update will likely show continued pressure at the pump, driven by ongoing Middle East disruptions that have roiled global oil markets since early March. The rapid weekly increases are not typical seasonal patterns.

A driver filling a 15-gallon tank today pays roughly $68, compared to $57 a year ago—a difference of $165 per fill-up over a month. These price movements directly impact household budgets, small business operating costs, and inflation readings that shape economic policy decisions across the Trump administration. The primary culprit is not domestic policy but international supply disruption. Since early March 2026, traffic through the Strait of Hormuz has been suspended following Middle East clashes, cutting off approximately 20 million barrels per day of oil and refined fuel imports. This blockage has pushed gasoline futures toward 4-year highs and continues to drive price volatility at the pump regardless of other market conditions.

Why Are Gas Prices Rising Today?

The two-week, 50-cent increase from April cannot be explained by normal supply-demand cycles. Refineries are operating near capacity, yet prices keep climbing because the market is pricing in scarcity. The Strait of Hormuz disruption is acute—it’s not a temporary issue or a geopolitical rumor, but an actual cessation of traffic through one of the world’s most critical choke points for oil and gasoline shipments. Global oil prices are responding to this supply shock, and U.S.

refineries pass these costs through almost immediately. A barrel of crude oil that refiners secured three weeks ago at $75 is now being replaced by crude at $82 or higher. Even if refinery output is stable, the input costs are rising. For consumers, this translates to the 25-cent weekly jump seen in the first week of May. The second consecutive 25-cent increase, reported as of May 7, signals that the market expected further escalation—likely driven by fresh Middle East clashes that are pushing long-term price expectations upward.

Regional Price Divides and State-by-State Reality

gas prices vary dramatically across the country, and understanding these regional differences reveals how policy, refinery access, and state taxes drive the pump price you actually pay. California leads the nation at $6.16 per gallon, followed by Washington at $5.76, Hawaii at $5.66, and Oregon at $5.34. These West Coast and Pacific states face unique supply constraints—fewer refineries in the region, stricter fuel blends required by state environmental regulations, and greater distance from major refinery hubs in the Midwest and Gulf Coast. In contrast, Oklahoma residents face the lowest pump prices in the nation at $3.98 per gallon, while Mississippi ($4.00), Louisiana ($4.02), and Arkansas ($4.02) round out the cheapest markets.

These southern states benefit from proximity to Gulf Coast refineries, lower state fuel taxes, and lighter environmental regulations that allow cheaper fuel blends. A driver in Oklahoma pays approximately $2.18 less per gallon than someone pumping gas in California—a $32 difference on a 15-gallon fill-up. The middle-tier states tell an important story about the 50-cent increase nationally. Moderate-price states like Texas ($4.09), Georgia ($4.09), and Alabama ($4.10) are seeing prices climb just as fast as California and Washington in percentage terms, but they started from a lower base. For lower-income households in these states, the psychological and financial impact of a 25-cent weekly jump is compounded because their gas budget is a larger share of discretionary income.

The Strait of Hormuz Chokepoint and Global Oil Disruption

The economic and geopolitical significance of the Strait of Hormuz disruption cannot be overstated. This narrow waterway between Iran and Oman handles approximately 20 million barrels per day of crude oil and refined products—roughly 20 percent of the world’s oil supply. When traffic suspended in early March 2026 following military clashes in the region, it created an immediate and ongoing shortage in global markets. Refined gasoline, diesel, and jet fuel that would normally flow from Middle Eastern and Gulf-adjacent refineries must now be sourced from alternative suppliers or diverted from other markets.

The U.S. Strategic Petroleum Reserve can help smooth short-term spikes, but it cannot replace 20 million barrels per day of lost global production indefinitely. The result is that futures prices for gasoline—the prices that refineries lock in today for fuel they will produce tomorrow—are at 4-year highs. This is not a Trump administration policy issue in the narrow sense of tariffs or domestic regulation, but it is directly relevant to government accountability because the administration’s response to the disruption will shape economic outcomes for the remainder of 2026. The administration has not publicly released specific details on strategic reserve drawdowns or diplomatic efforts to reopen the Strait, but the absence of significant price volatility relative to the supply shock suggests some degree of strategic planning is in place.

Consumer Impact and Household Budget Realities

A 50-cent increase in two weeks sounds abstract until you calculate it against actual driving habits. The average American drives about 14,000 miles per year, which translates to roughly 620 gallons annually at 22.5 miles per gallon (a reasonable estimate for a mid-size sedan). A $1.40-per-gallon increase year-over-year costs households $868 more per year. For households already stretched on rent, childcare, and groceries, this is material. Small business owners face even starker tradeoffs.

A delivery business with 10 vehicles might spend $80,000 annually on fuel at $3 per gallon; at $4.55, that same business is spending $122,000—a $42,000 hit to operating costs. These businesses have limited ability to pass costs directly to customers without losing price-sensitive accounts. The result is margin compression, deferred hiring, or reduced service. For lower-income households, the impact on purchasing power is disproportionate. A family earning $35,000 annually spends about 5-6 percent of their income on gasoline when prices are at $3.00; at $4.55, that share rises to 7-8 percent. Policy options—gas tax holidays, subsidies, strategic reserve releases—all have fiscal implications that extend beyond the pump and into long-term budget debates.

Supply Chain Vulnerabilities and Refinery Constraints

One critical limitation to understand: even if the Strait of Hormuz reopened tomorrow, refined gasoline prices would not fall immediately back to $3 levels. Refinery capacity globally is constrained. Several major refineries worldwide have shut down in recent years due to age, environmental regulations, and transition to renewable fuels investment. The U.S. has seen little new refinery capacity added in decades.

When global supply contracts, the market doesn’t just see lower fuel flowing into pipelines—it sees refineries running flat-out to produce what they can, and the result is less-flexible pricing. Crude oil at $75 per barrel moving through an undersized refinery sector results in gasoline at $4.50 per gallon, not $3.00. Reopening the Strait would help, but the structural constraint—insufficient refining capacity—is a longer-term issue that won’t be solved by geopolitics alone. A further warning: if refinery outages occur (scheduled maintenance, accidents, winter weather impacts), prices could spike further. In May 2024, a refinery fire in Louisiana temporarily tightened market conditions and drove prices up an additional 15-20 cents in affected regions within days. The current environment, with limited spare capacity and a supply constraint that is genuinely binding, makes the market fragile.

Government Policy Response and Strategic Reserves

The Trump administration has several policy tools at its disposal, though each comes with tradeoffs. The Strategic Petroleum Reserve (SPR) can be drawn down to inject supply into the market and theoretically lower prices. During the 2021-2022 inflation crisis, the Biden administration authorized the largest SPR release in history, injecting up to one million barrels per day into the market.

This provided temporary relief but did not prevent prices from remaining elevated for extended periods. The administration could also coordinate internationally to increase production from allied nations (Saudi Arabia, UAE, Canada) or pursue diplomatic channels to reopen the Strait. Tariffs on imported fuel or price controls are theoretically possible but carry risks—price caps create shortages and long-term supply problems, as historical examples (1970s-era gasoline lines) demonstrate. Tax policy (temporary suspension of federal fuel taxes) would cost the federal budget $5-10 billion monthly but would provide immediate relief to consumers.

Looking Forward—Where Are Gas Prices Headed?

The trajectory of gas prices through May and June depends almost entirely on Middle East developments and whether the Strait of Hormuz remains disrupted. If the shipping lane reopens, prices could fall $0.50 to $1.00 per gallon within 2-3 weeks as market expectations adjust. If clashes escalate and the blockade hardens, prices could rise another $0.50 per gallon before summer driving season arrives.

Summer driving season (Memorial Day through Labor Day) typically sees prices rise 10-15 percent above spring levels due to increased demand and required summer fuel blends that cost more to produce. If the base price is already at $4.55 and supply remains constrained, summer prices could reach $5.00 nationally by June or July, with West Coast prices potentially exceeding $7.00 per gallon. These are not alarmist projections—they follow straightforward supply-demand logic given current constraints.

Conclusion

Gas prices today stand at $4.55 per gallon nationally as of May 7, 2026, with sharp 25-cent weekly increases driven by the Strait of Hormuz disruption that began in March. Consumers are paying $1.40 more per gallon than a year ago, with regional variation from $3.98 in Oklahoma to $6.16 in California. The primary driver is a geopolitical supply shock affecting 20 million barrels per day of global oil flow, not domestic policy failures or refinery underperformance.

For May 17 data and forward-looking guidance, monitor AAA’s daily fuel price tracker, the U.S. Energy Information Administration’s weekly reports, and news on Middle East developments that could affect Strait of Hormuz shipping. The administration’s response strategy—whether through strategic reserve management, diplomatic engagement, or alternative policy tools—will meaningfully shape household and business costs through the remainder of 2026.
