Gas prices in Texas hit $4.09 per gallon for regular unleaded as of May 6, 2026, marking a 24-cent jump from the previous week and representing the sharpest climb Texas drivers have seen in months. This Monday fuel update shows Texas prices remain significantly below the national average of $4.536 per gallon—giving Texas residents a 45-cent advantage compared to drivers nationwide—but the rapid weekly increases are putting pressure on household budgets and transportation costs. A Houston driver filling a 15-gallon tank pays roughly $61 today, compared to just $53 the same week last year, a $8 difference that compounds across multiple fill-ups.
The price surge reflects a confluence of geopolitical pressures and global supply chain disruptions that have cascaded through Texas refineries and fuel distribution networks. Tensions between the U.S. and Iran, combined with ongoing shipping disruptions in the Strait of Hormuz—a critical chokepoint for global oil transport—have tightened crude oil supplies and pushed wholesale prices upward. While reports indicate U.S.-Iran negotiations on a 14-point deal to end hostilities are underway, no final agreement has been reached, leaving market uncertainty and price volatility in place for the foreseeable future.

What Are the Latest Gas Prices Across Texas?
Texas’s statewide average of $4.09 per gallon masks significant regional variation, with West Texas experiencing the steepest prices and major urban centers clustered around the $4 mark. Brewster County in the remote far west of the state has reached approximately $4.60 per gallon—the highest in Texas—reflecting both geographic isolation and limited refinery access. This creates a real-world consequence: a resident of Brewster County pays roughly 51 cents more per gallon than the state average, making a weekly fill-up 7-8 dollars more expensive than someone driving in more competitive markets.
San Antonio and the surrounding Hill Country region are averaging $4.13 per gallon as of May 5, 2026, with a week-over-week increase of 28 cents—jumping from $3.85 just seven days prior. The Dallas-Fort Worth metroplex, Texas’s second-largest metropolitan area, shows prices hovering just above $4 per gallon in Tarrant and Dallas counties, suggesting the metropolitan markets have more competitive supply chains and lower margins than rural or smaller urban areas. Drivers in these major cities should expect to see price variation from station to station; even within a single city, fuel prices can swing 5-15 cents depending on station brand, location, and recent inventory restocking.
Why Are Texas Gas Prices Surging So Quickly?
The primary driver of this rapid price increase is geopolitical instability in the Middle East, specifically escalating tensions between the U.S. and Iran that have disrupted global oil supplies. The Strait of Hormuz, through which roughly one-third of the world’s seaborne oil passes daily, has become a flashpoint for shipping disruptions. These disruptions don’t directly affect U.S. domestic oil production, but they affect global crude oil pricing, which in turn affects what U.S.
refineries pay for raw materials. When crude oil costs refineries more, those costs flow downstream to wholesale fuel distributors and ultimately to gas pumps across Texas. A critical limitation of the current situation is that market anticipation plays as large a role as actual supply losses. Traders and petroleum investors have bid up crude oil prices partly on the *fear* of future disruptions, not just current disruptions. This means prices could decline rapidly if negotiations succeed or geopolitical tensions ease—or conversely, they could spike further if events escalate. The U.S.-Iran negotiations on a 14-point deal represent a potential off-ramp, but given the complexity of international diplomacy and historical precedent of failed negotiations, there’s no guarantee of a timeline or outcome.
How Do Texas Prices Vary by Region?
Texas is large enough that geography creates meaningful price tiers. Houston and the Gulf Coast refineries, which process 13% of U.S. crude oil into finished fuel products, benefit from direct access to massive petroleum infrastructure and can supply fuel to a dense population efficiently. This competitive advantage shows up in slightly lower prices than inland areas.
Meanwhile, San Antonio, Austin, and Dallas residents are further from refineries and depend on fuel transported via pipeline or truck, adding distribution costs that get passed to consumers. A specific example: On the same day, a San Antonio driver paid $4.13 per gallon while a Houston-area driver in a competitive market might have paid $3.98—a 15-cent difference that represents supply chain efficiency. West Texas and rural areas like Brewster County face the harshest reality: limited refinery access, longer transport distances, and smaller market volumes mean fewer competitors and higher prices. For someone commuting between these regions—say, a rancher or long-haul driver—the price variation directly impacts operational costs and profit margins, sometimes determining whether a trip is economically viable.
How Do Texas Prices Compare to the National Average?
The U.S. national average of $4.536 per gallon places Texas in a relatively favorable position: Texas drivers enjoy a 45-cent-per-gallon advantage compared to the national median. This matters substantially at scale. A household that fills up 40 gallons per week saves $18 per week, or roughly $936 per year, simply by living in Texas rather than states like California, Hawaii, or the Northeast, where prices consistently exceed $5 per gallon.
For commercial fleets and delivery services, this advantage compounds into thousands of dollars in annual fuel cost savings. However, this comparison comes with an important caveat: Texas’s relatively low prices reflect its status as a refinery hub and oil-producing state, not a permanent guarantee. If refinery capacity were disrupted by weather, mechanical failure, or accident, or if geopolitical disruptions worsened, Texas could quickly fall in line with national price trends or even exceed them. The 45-cent advantage is real today, but it’s contingent on infrastructure stability and global market conditions that can shift rapidly.
What Role Do Geopolitical Tensions Play in Daily Prices?
The current tensions with Iran represent a direct threat to a significant portion of global crude oil supply. The Strait of Hormuz—a 21-mile-wide waterway between Iran and Oman—is navigated by roughly 21,000 oil tankers annually. Any disruption, whether from military action, accidents, or blockade attempts, immediately signals to global markets that oil supply will be constrained. Traders respond by bidding up the price of crude oil futures, which flows through to refinery costs within hours.
The ongoing U.S.-Iran negotiations on a 14-point deal provide some hope for de-escalation, but these talks remain fragile and unresolved. A final agreement could bring crude oil prices down by $10-20 per barrel, which would translate to roughly 25-50 cents per gallon at the pump. Conversely, if negotiations collapse or tensions escalate, prices could rise another 30-75 cents per gallon. This uncertainty creates a warning for consumers: locking in fuel or making major travel plans should factor in that prices could move significantly in either direction over the coming weeks.
How Does This Compare to Historical Gas Price Cycles?
Texas hasn’t seen prices this high since summer 2022, when geopolitical disruptions following Russia’s invasion of Ukraine drove crude oil to $120+ per barrel. The $4.09 current price is lower than summer 2022’s peaks (which reached $4.50+) but in the same ballpark. Year-over-year, the comparison is starker: May 2025 prices averaged $2.77 per gallon, meaning the current price is $1.32 higher—a 47% increase in just twelve months.
This historical pattern suggests that when geopolitical disruptions ease, prices fall with surprising speed. In summer 2022, prices dropped from peaks to $3.20 within 12 weeks as supply chain fears eased. If the Iran negotiations succeed, Texas drivers could see similar relief, potentially dropping to the $3.50-3.75 range. However, if disruptions worsen, historical precedent suggests prices could test $4.50-5.00 per gallon—territory not seen in Texas for three years.
What’s the Outlook for Texas Gas Prices in the Coming Weeks?
The trajectory of Texas gas prices over the next month hinges almost entirely on two variables: the outcome of U.S.-Iran negotiations and any actual disruptions to shipping in the Strait of Hormuz. If negotiations produce a deal or substantive progress is announced, crude oil prices typically fall within days, cascading to pump prices within 1-2 weeks. If negotiations stall or tensions escalate, prices will likely continue climbing, potentially reaching $4.30-4.50 per gallon by late May.
Summer seasonal factors will also play a role. Refineries typically produce more expensive summer-blend gasoline starting in May, which can add 10-25 cents per gallon. Combined with geopolitical uncertainty, this suggests Texas drivers should prepare for the possibility of $4.20-4.40 per gallon prices through June, with potential relief in July if geopolitical tensions ease. Monitoring news about Iran negotiations and oil tanker movements in the Strait of Hormuz provides the best early indicator of which direction prices will move.
Conclusion
Texas gas prices stand at $4.09 per gallon as of May 6, 2026, reflecting a 24-cent weekly increase and marking the highest prices since summer 2022. While Texas maintains a significant 45-cent advantage over the national average, the rapid weekly increases underscore the direct impact of geopolitical tensions between the U.S. and Iran, combined with shipping disruptions affecting global crude oil supplies. Regional variation across Texas—from Brewster County’s $4.60 to Dallas-Fort Worth’s $4.00—demonstrates how geographic isolation and refinery access create meaningful price disparities that affect household budgets and business operations differently across the state. The coming weeks will determine whether Texas prices stabilize, decline, or continue climbing.
Success in U.S.-Iran negotiations on a 14-point deal could bring swift relief, potentially dropping prices toward $3.50-3.75 per gallon. Conversely, escalation or failed negotiations could push prices toward $4.50 per gallon by summer. Texas drivers should monitor official data sources—AAA’s real-time gas price tracking, the U.S. Energy Information Administration (EIA), and GasBuddy—and adjust travel plans and fuel purchases based on the week’s geopolitical developments. For households and businesses dependent on transportation, planning ahead for potential price volatility represents the most practical response to current market uncertainty.
