Fuel markets remain unstable in 2026 because a confluence of geopolitical disruptions, regional supply shortages, and conflicting economic forecasts has created sustained volatility with no clear resolution in sight. The national average gas price stood at $4.56 per gallon on May 21, 2026—$1.38 higher than the same week in May 2025—and these elevated prices are expected to persist for months despite conflicting predictions from major financial institutions about whether they will climb further or finally decline. A California driver paying $6.15 per gallon faces gas costs that are nearly 56% higher than an Oklahoma driver paying $3.94, a gap that underscores how fragmented and unstable regional markets have become.
The instability stems from three fundamental problems: first, the closure of the Strait of Hormuz since February 28, 2026, has effectively removed approximately 20% of global oil supply from circulation; second, Middle Eastern producers collectively shut in 10.5 million barrels per day of crude oil production as of April 2026; and third, U.S. gasoline inventories fell for 14 consecutive weeks through mid-May, suggesting domestic supply is tightening even as global demand forecasts indicate only marginal increases ahead. These competing pressures—supply destruction on one side, weak demand growth on the other—have created a market caught between deflationary and inflationary forces, with consumers bearing the cost of this uncertainty.

What Geopolitical Disruptions Are Driving Current Fuel Market Volatility
The Strait of Hormuz closure represents the single most consequential supply shock affecting global oil markets today. This waterway previously transported approximately 20% of the world’s crude oil supply, making it one of the most critical chokepoints in the global energy infrastructure. When shipping through the strait became impossible in late February 2026, crude oil suppliers worldwide faced a sudden and unexpected redirection of shipments to alternative routes—a process that added shipping time, increased transportation costs, and created immediate uncertainty about long-term alternatives. The International Energy Agency has acknowledged that this closure is one of the primary reasons prices have remained volatile throughout spring 2026, despite widespread expectations that 2026 would bring price relief compared to 2025.
Beyond the Strait, the deliberate production cuts by Middle Eastern producers have compounded the supply shock. Iraq, Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, and Bahrain collectively shut in 10.5 million barrels per day of crude oil production in April 2026. These cuts appear to be coordinated responses to both the geopolitical tensions affecting the region and attempts to support crude oil prices amid the supply disruption. However, the impact differs dramatically across regions—California has absorbed much of the supply tightness, reflected in its $6.15-per-gallon average price, while states like Louisiana and Mississippi have remained relatively insulated, with prices near $4.00 per gallon. This regional imbalance reflects differences in refinery capacity, import dependencies, and existing inventory levels, creating a market that behaves very differently depending on geography.
Inventory Depletion and Domestic Supply Constraints
U.S. gasoline inventories have fallen for 14 consecutive weeks as of mid-May 2026, a trend that contradicts typical seasonal patterns where spring inventory builds should be occurring ahead of the summer driving season. This depletion suggests that domestic refineries are struggling to keep pace with consumption, even as demand growth has remained modest. The Energy Information Administration has identified this inventory decline as a significant constraint on price stability, noting that lower inventory buffers leave the market more vulnerable to sudden disruptions in supply or unexpected spikes in demand. If a hurricane disrupted Gulf Coast refining capacity or if Middle Eastern supply cuts accelerated, gasoline inventories would provide minimal cushion to absorb the shock—a limitation that policy planners in Washington have explicitly warned about.
The inventory problem is compounded by refinery utilization rates, which have remained elevated throughout the spring despite adequate global crude supplies on a theoretical basis. This mismatch suggests that refineries are converting crude into gasoline at maximum rates, but the output is being consumed faster than it can be replaced. For context, during the spring of 2025, inventories would typically be building, providing a comfortable buffer for the high-demand summer season. In 2026, however, refiners are fighting to maintain minimal safety stocks, leaving zero margin for error if production falters or demand spikes unexpectedly. The limitation here is significant: refinery infrastructure is essentially maxed out, meaning prices cannot be brought down through increased domestic production without first addressing the supply disruptions affecting crude oil availability.
Conflicting Price Forecasts and Market Expectations
Three major institutions have offered competing predictions for where crude oil and gasoline prices will move through the remainder of 2026, and their disagreement underscores the genuine uncertainty driving market instability. The Energy Information Administration forecasts that Brent crude will average around $106 per barrel in May and June 2026, then decline to $89 per barrel in the fourth quarter and $79 per barrel in 2027—a trajectory suggesting prices have peaked and will gradually normalize. The EIA simultaneously forecasts that retail gasoline prices will be 6% lower in 2026 compared to 2025, with a modest 1% increase in 2027, implying some relief is already expected in the back half of this year. J.P.
Morgan Global Research, by contrast, forecasts that Brent crude will average around $60 per barrel across 2026—a price point roughly $45 below the EIA’s May-June forecast and $29 below the EIA’s year-end Q4 forecast. This forecast suggests that crude prices are significantly overvalued at current levels and will experience a sharp correction, trickling down to gasoline pumps within weeks. The disagreement reflects fundamental uncertainty about whether the Strait of Hormuz closure and Middle Eastern production cuts are permanent features of the market or temporary disruptions that will resolve as geopolitical conditions normalize. For consumers and businesses planning fuel budgets, this uncertainty is itself destabilizing—your company cannot confidently forecast transportation costs when credible forecasters differ by more than $45 per barrel on Brent crude prices.
How Regional Price Variations Create Economic Inequity and Market Fragmentation
The spread between the cheapest and most expensive gas prices in America has become severe enough to warrant serious policy attention. California drivers at $6.15 per gallon are paying more than 56% above the national average, while Oklahoma drivers at $3.94 per gallon are enjoying prices nearly one-third lower than the national average. Hawaii at $5.64 and Washington at $5.77 face their own premium pricing due to geographic isolation and refined product import dependencies. For a household filling up 12 gallons per week—a conservative estimate for modern driving patterns—the difference between California and Oklahoma prices amounts to $27.24 per week, or roughly $1,420 per year on gas costs alone. This fragmentation creates real economic disadvantage for households and businesses in high-price states.
A transportation or delivery company operating in California absorbs these fuel premiums as a cost increase, which gets passed to consumers through higher prices for goods and services. Small businesses cannot easily relocate to lower-cost states to escape the penalty. Meanwhile, crude oil prices that would justify $4.50 per gallon in Oklahoma should theoretically justify lower prices everywhere, but infrastructure constraints and supply chain dependencies prevent that theoretical equality from materializing. The practical tradeoff is that some regions benefit from geographic advantages in oil refining and imports, while others pay a permanent tax on transportation. Without federal intervention to address these supply chain imbalances, the regional inequity will persist throughout 2026 and beyond.
Oil Infrastructure Damage and Long-Term Price Recovery Timeline
The oil infrastructure damage resulting from ongoing geopolitical conflict in the Middle East creates one of the most significant constraints on price normalization. According to analysis from NC State University economists citing Middle East production data, the infrastructure damage from conflict is creating a recovery timeline of three to five years before prices can be expected to normalize to historical ranges. This timeline is not a forecast but rather a structural constraint—it takes years to rebuild refineries, pipeline networks, and production facilities damaged by conflict. Even if geopolitical tensions resolve tomorrow, the physical damage to infrastructure means that production capacity simply cannot return to pre-conflict levels for years. This long-term constraint is often overlooked in short-term price forecasts.
While the EIA forecasts Brent crude at $79 per barrel in 2027, and J.P. Morgan forecasts $60 per barrel for 2026, both projections may prove optimistic if infrastructure recovery lags expectations. A single damaged refinery complex in Iraq or a damaged pipeline in Saudi Arabia could delay recovery by months or years, pushing normalized prices further into the future. For consumers hoping that 2027 will bring relief, the limitation is that even optimistic scenarios assume significant geopolitical stabilization and successful reconstruction, neither of which is guaranteed. The warning here is explicit: do not assume that fuel prices will return to 2024 levels in the near term, even if geopolitical tensions ease.
Global Demand Weakness and Its Contradictory Effect on Prices
Global oil demand is expected to increase by only 0.2 million barrels per day in 2026, down from a prior-month forecast of 0.6 million barrels per day growth. This downward revision in demand expectations should theoretically put downward pressure on prices, suggesting that the global economy is not growing as robustly as previously anticipated. Weak economic growth typically translates to weaker fuel demand, which should drag prices lower. However, the supply constraints from the Strait of Hormuz closure and Middle Eastern production cuts are powerful enough to overwhelm the demand-dampening effect, keeping prices elevated despite the weakness in growth expectations.
The contradiction is important to understand: prices are not high because the world desperately needs more oil for economic growth. Prices are high because available oil supply has been artificially constrained, and that constraint is binding. If global demand were surging, prices would be even higher. Conversely, if the supply constraints were removed, prices would likely fall significantly even with the modest demand growth currently expected. This highlights why geopolitical resolution is so central to the price outlook—demand is not the driver of elevated prices in 2026.
What 2026 Fiscal and Monetary Policy May Mean for Fuel Price Expectations
Federal policy responses to fuel prices typically take one of two forms: either attempts to increase supply (including potential emergency releases from the Strategic Petroleum Reserve) or attempts to address demand (through policy constraints on consumption or economic stimulus reductions). The Trump administration has the authority to release oil from the Strategic Petroleum Reserve, a tool that could add temporary supply to the market and potentially moderate prices, though such releases are politically contentious and typically reserved for genuine emergencies. The administration also has limited ability to influence Middle Eastern producers’ production decisions, though diplomatic pressure campaigns remain an option. Looking ahead, the trajectory of fuel prices through 2026 and into 2027 will depend almost entirely on how quickly the Strait of Hormuz reopens for shipping and how rapidly Middle Eastern infrastructure damage is repaired.
If both normalizations occur within the next six months, the EIA’s forecast of declining prices into 2027 becomes plausible. If normalization is delayed by a year or more, the J.P. Morgan forecast of elevated prices persisting well into 2026 and potentially into 2027 becomes more likely. The market remains unusually sensitive to headline geopolitical news, and that sensitivity is unlikely to fade until supply constraints demonstrably ease.
Conclusion
Fuel market instability in 2026 is the direct result of constrained global supply colliding with weak demand growth, creating an environment where prices remain elevated despite economic weakness that would normally drag them down. The national average of $4.56 per gallon represents a genuine hardship for consumers and businesses, particularly in high-cost regions like California and Hawaii, and relief appears unlikely before the end of 2026 even under optimistic scenarios. The Strait of Hormuz closure and Middle Eastern production cuts have created supply constraints that no amount of demand reduction or policy tinkering can quickly reverse.
Consumers and businesses should plan for fuel prices to remain in the $4.00-$5.50 range for gasoline through the remainder of 2026, with significant regional variation. Monitor developments in the Middle East, particularly regarding infrastructure repairs and political stabilization, as these factors will determine whether the back-half-of-2026 price declines that the EIA predicts will actually materialize. If infrastructure repair timelines slip beyond optimistic expectations, prices could remain elevated well into 2027, requiring longer-term adjustments to household and business budgets.
