Oil prices are dominating headlines because the world is experiencing one of the worst energy supply crises in decades. On May 18, 2026, gasoline averaged $3.72 per gallon—up 73.81% compared to a year ago—while crude oil trades near $107.72 per barrel, reflecting a 73.34% year-over-year surge. The shock extends beyond pump prices: the International Energy Agency and World Bank now forecast global energy prices could jump 24% in 2026, the largest spike since Russia’s invasion of Ukraine, creating ripple effects across inflation, consumer spending, and government budgets worldwide. The primary culprit is geopolitical conflict in the Middle East. Since the U.S.-Israeli war against Iran began on February 28, 2026, the Strait of Hormuz—the world’s most critical oil chokepoint—has been effectively shut down, disrupting nearly 20 million barrels per day of crude oil and refined product flows.
Six Gulf oil-producing nations (Iraq, Saudi Arabia, Kuwait, UAE, Qatar, and Bahrain) have collectively shut in 10.5 million barrels per day of production since April. This represents the largest oil supply shock on record and explains why crude oil prices have climbed more than 45% since the conflict began, with Brent crude peaking at $138 per barrel on April 7. Understanding why gas prices remain elevated despite recent market adjustments is essential for consumers, policymakers, and businesses making spending and investment decisions. The answers reveal how geopolitical events far from U.S. gas stations directly determine what Americans pay at the pump.

How Geopolitical Conflict Created the Largest Oil Supply Shock on Record
The closure of the Strait of Hormuz represents an unprecedented disruption to global oil markets. One of the world’s most critical waterways, the Strait normally allows approximately 20 million barrels per day of crude oil and refined products to flow from the Persian Gulf to global markets. When regional tensions escalated into active conflict, shipping companies stopped transiting the strait, effectively cutting off a pipeline that supplies oil to refineries across Europe, Asia, and beyond. For perspective, this single disruption is equivalent to removing nearly the entire daily crude oil production of the United States, Russia, and Saudi Arabia combined from the global market.
The supply shock was compounded by coordinated production cuts from Gulf oil states. In April 2026, Iraq, Saudi Arabia, Kuwait, UAE, Qatar, and Bahrain shut in 10.5 million barrels per day of crude oil production. Saudi Arabia, typically the world’s largest swing producer that can increase or decrease output to stabilize markets, was forced to curtail production rather than expand it—removing the traditional pressure valve from the global oil market. The World Bank calculated that this combined disruption triggered the largest oil supply shock in recorded history, exceeding even the Arab Oil Embargo of 1973. When production and transit both collapse simultaneously, prices spike rapidly and can remain elevated for months.
The Staggering Price Movements That Reveal Market Panic
Crude oil prices have moved with unprecedented volatility since the conflict began. Brent crude oil started 2026 at $61 per barrel, climbing to $118 by the end of the first quarter—the largest inflation-adjusted quarterly increase since 1988. Within weeks of the February 28 conflict onset, Brent crude reached $138 on April 7, before settling into the $106-$111 range by mid-May. This pattern of spike and partial correction is characteristic of energy markets during geopolitical crises: initial panic buying drives prices to unsustainable levels, then traders and governments begin planning for extended disruption, creating a slightly lower equilibrium price that remains far above pre-crisis levels. The severity of the price shock is visible in year-over-year comparisons. As of May 18, 2026, crude oil is up 73.34% compared to the same period in 2025.
Gasoline prices have climbed 73.81% year-over-year, from roughly $2.14 per gallon to $3.72 per gallon. Even more troubling, prices continue climbing in the short term: gasoline is up 19.42% in just the past month and crude has gained 23.22% over the same period. These rapid increases indicate that the market is not yet finding a stable equilibrium and suggests prices could move higher or lower suddenly based on developments in the Middle East. A critical limitation of price forecasting during geopolitical crises is that predictions depend entirely on conflict resolution timelines that are inherently unpredictable. The International Energy Agency warns that the oil market could remain severely undersupplied until October 2026 even if fighting ends next month—suggesting 5+ months of constrained supply ahead. This means consumers and businesses should plan for sustained high prices rather than a rapid return to pre-crisis levels.
Global Oil Supply and Demand Imbalance Creates a Perfect Storm
Beyond production cuts and transit disruptions, the fundamental supply-and-demand imbalance has worsened. Global oil inventories are expected to fall by an average of 8.5 million barrels per day throughout the second quarter of 2026. When inventories fall, it signals that global consumption is outpacing production—a condition that typically sustains elevated prices. Energy markets require both production and inventory stability; when either is absent, prices rise as refineries and traders bid for limited barrels. The current situation has both factors working against consumers. The International Energy Agency estimates that crude oil prices will remain elevated through the spring and early summer, with Brent crude expected to average around $106 per barrel through May and June 2026.
This is substantially higher than the $61 per barrel level that prevailed in early 2026, reflecting the market’s expectation that Middle East disruption will persist for months. Some relief is projected: the IEA forecasts crude oil prices will decline to an average of $89 per barrel by the fourth quarter of 2026, assuming Middle East production rises and the Strait of Hormuz gradually reopens. However, this optimistic scenario faces significant downside risks. If the conflict expands or intensifies, additional producers could be drawn into the disruption, creating an even larger supply shock. If peace negotiations stall, the disruption could extend past October 2026, keeping prices elevated well into 2027. Conversely, a rapid conflict resolution and restoration of shipping through the Strait could create excess supply and drive prices lower faster than forecasted. The uncertainty itself contributes to elevated prices, as traders build risk premiums into contracts.
What History Teaches About Energy Crises and Price Recovery Timelines
Comparing the current crisis to previous oil shocks reveals both similarities and differences. The 1973 Arab Oil Embargo, which cut oil supplies by approximately 5% globally, drove crude prices from roughly $25 per barrel to over $100 in today’s dollars and created lasting economic damage. The current crisis involves a much larger percentage of global supply—approximately 10-11% of worldwide production is offline, compared to roughly 5% during the 1973 embargo. The disruption is therefore more severe than the embargo, yet the price response has been somewhat more muted, likely because the global economy is less oil-dependent than it was in the 1970s and strategic petroleum reserves exist to buffer short-term supply shocks. The 1990 Iraqi invasion of Kuwait disrupted about 4 million barrels per day of production and caused crude oil prices to spike from $15 to over $40 per barrel (in nominal terms). That disruption lasted approximately 7 months before Kuwait returned to meaningful production.
The current Middle East disruption is substantially larger—10.5 million barrels per day from production cuts alone, plus the 20 million barrels per day transiting the Strait of Hormuz. If historical patterns hold, and if the conflict follows a similar timeline, prices could remain elevated for 6-12 months, with gradual decline as production gradually restarts. One critical difference from past crises is the speed of recovery. Previous oil shocks involved infrastructure damage that took months to repair, but the current disruption is primarily geopolitical—when the conflict ends, production can resume relatively quickly. This suggests that prices could fall faster than they rose once a ceasefire is achieved, potentially creating a sharp correction in both oil and gasoline prices. Consumers and businesses should be prepared for volatility in both directions.
The Consumer Impact: Higher Prices at the Pump and Beyond
The $3.72 per gallon gasoline price represents a direct cost increase to American households. For a consumer with a 15-gallon gas tank, filling up now costs about $55.80 compared to roughly $32 a year ago—an additional $23 per fill-up or roughly $92 per month for typical driving. Multiplied across 130 million American households and vehicles, this represents roughly $12 billion in additional monthly consumer spending on gasoline alone, money that would otherwise be available for food, housing, healthcare, and savings. However, the impact extends far beyond individual gas pumps. Higher crude and refined product prices feed into transportation costs for trucks, ships, and aircraft, which increases prices across supply chains. Groceries cost more to transport; goods shipped internationally face higher logistics costs; heating oil prices rise alongside crude oil prices.
The World Bank projects energy prices will surge 24% across the entire economy in 2026—the highest increase since Russia’s invasion of Ukraine—suggesting that consumers will encounter higher prices not just at the pump but throughout their household budgets. A warning for consumers and policymakers: the 73% year-over-year increase in gasoline prices has already begun to appear in inflation measurements. The Federal Reserve and Biden administration face pressure to explain sustained inflation to American voters, yet they have limited policy tools to address a geopolitical supply shock originating in the Middle East. Strategies like releasing strategic petroleum reserves provide only temporary relief; interest rate policy cannot address a supply shortage; trade policy cannot change global oil market dynamics. This political pressure may drive policymakers toward escalatory actions in the Middle East, potentially worsening the very conflict causing the supply disruption. Consumers should monitor policy developments carefully, as geopolitical actions taken in response to oil prices could inadvertently extend the crisis.
Comparing Transportation Costs and Economic Competitiveness
High fuel prices create uneven impacts across industries. Industries that depend on transportation—trucking, agriculture, logistics, air travel—face margin compression as fuel costs rise. A trucking company with a fleet of 100 long-haul trucks might see fuel costs jump from $400,000 per month to $700,000 per month, forcing either service cuts, price increases, or reduced profitability. Conversely, industries that consume minimal fuel—technology services, financial services, telecommunications—see little direct impact from oil price increases. This creates competitive distortions where fuel-dependent industries lose pricing power relative to service-based competitors.
Agricultural producers provide a concrete example of this pressure. Farming requires fuel for tractors, irrigation pumps, transportation to market, and fertilizer production (which relies on energy). A 73% increase in energy prices compounds into higher feed costs for livestock, higher grain prices, and higher transportation costs for agricultural products. A corn farmer purchasing fuel at $3.72 per gallon versus $2.14 per gallon faces significantly reduced margins, while a food technology company experiences minimal direct impact. These differences can shift competitive advantages across economic sectors in ways that persist long after energy prices stabilize.
Recovery Timeline and What to Expect Through 2026
The International Energy Agency’s forecast provides the most detailed guidance on when prices might stabilize. According to current projections, oil markets will remain severely undersupplied through October 2026, suggesting prices will remain elevated—though potentially with some moderation—through the summer and fall. The IEA expects average crude oil prices of approximately $89 per barrel in the fourth quarter of 2026, assuming the Middle East conflict resolves and production restarts. At that price level, gasoline would likely trade in the range of $2.80-$3.00 per gallon—still elevated compared to early 2026 but significantly lower than current levels.
Looking beyond 2026, the sustainability of lower prices depends entirely on geopolitical developments. If Middle East producers restore production to pre-conflict levels and the Strait of Hormuz reopens fully, crude oil could drift toward $70-$80 per barrel levels, which would bring gasoline prices to approximately $2.40-$2.60 per gallon. This would represent meaningful relief for consumers but would still be above the $2.14 per gallon level seen in May 2025, reflecting the lasting impact of the supply shock. However, if the conflict persists, expands to other producers, or creates lasting infrastructure damage, prices could remain elevated well into 2027 and beyond. The range of possible outcomes is wide, making energy price planning unusually uncertain for both consumers and businesses.
Conclusion
Gas prices continue dominating headlines because they reflect a fundamental disruption to global oil supplies triggered by the Middle East conflict and the closure of the Strait of Hormuz. The 73% year-over-year increase in gasoline prices to $3.72 per gallon, and the 73% surge in crude oil to $107.72 per barrel, represent not merely market volatility but a genuine supply crisis—the largest oil supply shock on record affecting approximately 10-11% of global production. The disruption is expected to persist through at least October 2026, suggesting consumers, businesses, and policymakers should prepare for sustained elevated energy prices through the remainder of the year.
Forward-looking, the key question is not whether prices will eventually decline—they will, as Middle East conflict eventually resolves—but rather how rapidly that decline occurs and whether prices will return to pre-crisis levels. Current IEA forecasts suggest crude could reach $89 per barrel in Q4 2026, translating to gasoline near $2.80-$3.00 per gallon, but substantial uncertainty remains. Consumers should monitor developments in the Middle East carefully, as progress toward conflict resolution or escalation will be the primary driver of price movements in coming months. Policymakers should be wary of energy-driven inflation becoming entrenched in expectations, which could extend price pressures even after supply disruptions ease.
