What's Happening
The unthinkable has happened. The Strait of Hormuz — the narrow, 21-mile-wide chokepoint between Iran and Oman through which approximately 20% of the world's crude oil and liquefied natural gas flows daily — has been effectively blockaded, triggering the most severe energy supply disruption since Russia's 2022 invasion of Ukraine. The crisis, which escalated in mid-June 2026, has paralyzed tanker traffic through a waterway that handles an estimated 17 to 21 million barrels of crude oil per day, along with roughly one-fifth of global LNG shipments.
The immediate market reaction was swift and severe. WTI crude oil futures surged past $105 per barrel in the days following the disruption, up from approximately $78 per barrel in early June — a spike of more than 34% in under three weeks. Brent crude, the international benchmark, climbed above $108 per barrel. Energy traders, caught off guard by the speed and scale of the closure, scrambled to reprice risk across global petroleum markets.
For US drivers, the signal at the pump has already arrived. The national average gas price today has climbed sharply, with AAA reporting the national average crossing $3.89 per gallon as of late June 2026, up from $3.42 per gallon just four weeks earlier — a jump of 47 cents per gallon in less than a month. Premium grades in high-cost states are already brushing $5.00 per gallon or above.
The crisis has also accelerated a structural shift that energy analysts had long discussed but few expected to materialize this quickly: a frantic, multi-billion-dollar push to build alternative pipeline infrastructure across the Middle East, bypassing the Strait entirely. That pipeline boom is now underway — but it will take months, if not years, to meaningfully offset the lost throughput.
Data Snapshot
According to EIA data, the Strait of Hormuz handles between 17 and 21 million barrels of crude oil per day in normal conditions, representing approximately 20 to 21% of total global petroleum liquids consumption. The EIA's most recent Weekly Petroleum Status Report, released prior to the full blockade, showed US commercial crude oil inventories drawing down by 4.2 million barrels in a single week — a draw nearly double the five-year seasonal average of 2.1 million barrels for this time of year.
AAA reports the national average price per gallon of regular unleaded gasoline at $3.89 as of June 22, 2026, compared to $3.42 four weeks prior. WTI crude spot price has surged to approximately $105 per barrel, up from $78 per barrel in early June. Brent crude is trading near $108 per barrel. GasBuddy data shows the cheapest gas prices today concentrated in Gulf Coast states, where domestic refinery access provides a partial buffer, with some Texas stations still below $3.60 per gallon.
Why It Matters at the Pump
The rule of thumb that energy economists use — every $10 increase in crude oil prices translates to roughly 24 to 25 cents per gallon at the pump — helps illustrate the scale of what US drivers are now facing. With WTI up approximately $27 per barrel from its early June baseline, the math points to a potential 65-cent-per-gallon increase in retail gasoline prices once the full crude cost is absorbed through the refining and distribution chain. That process typically takes two to six weeks, meaning the worst of the price impact at the pump may not yet be fully reflected in the national average gas price.
Regional disparities are already pronounced. California, which operates under its own fuel blend requirements and carries the nation's highest state gasoline taxes, is seeing regular unleaded average above $4.85 per gallon, with premium grades at several Bay Area and Los Angeles stations exceeding $5.40. The West Coast is structurally most exposed to Middle East supply disruptions because West Coast refineries historically source a higher share of their crude from Persian Gulf producers.
The Midwest, which benefits from proximity to Cushing, Oklahoma — the primary US crude storage and pricing hub — and from Canadian pipeline imports, is showing more resilience. Chicago-area averages are running near $3.75 per gallon. The Gulf Coast, home to the largest concentration of US refining capacity, remains the most insulated region, with Houston-area prices near $3.55 per gallon. The Northeast, dependent on both imports and aging refinery infrastructure, is tracking closer to $4.10 per gallon on average.
What's Driving This
The Hormuz blockade is the proximate cause, but several compounding factors are amplifying its market impact. First, global crude inventories entered this crisis at below-average levels. The IEA's most recent Oil Market Report noted that OECD commercial inventories were running approximately 120 million barrels below the five-year average heading into June 2026 — leaving the market with minimal cushion to absorb a supply shock of this magnitude.
Second, OPEC+ had already implemented production cuts totaling approximately 3.66 million barrels per day relative to October 2022 baseline levels, with the alliance's most recent meeting in May 2026 extending those cuts through the end of the year. That means the cartel has limited spare capacity to rapidly compensate for Hormuz-related losses, though Saudi Arabia and the UAE have both signaled willingness to boost output if alternative export routes can be secured.
Third, the pipeline boom referenced by OilPrice.com reflects a real but slow-moving solution. The existing Abu Dhabi Crude Oil Pipeline — also known as the Habshan-Fujairah pipeline — has a capacity of approximately 1.5 million barrels per day and bypasses the Strait entirely, exporting through the UAE's east coast port of Fujairah. Saudi Arabia's East-West Pipeline (Petroline) can move up to 5 million barrels per day to Red Sea terminals. But combined, these alternative routes can handle only a fraction of the 17 to 21 million barrels per day that normally transits Hormuz. New pipeline capacity announcements are coming fast, but construction timelines measured in years mean near-term relief is limited.
Historical Context
The Strait of Hormuz has been threatened before, but never fully closed in the modern era of global petroleum markets. During the Iran-Iraq Tanker War of the 1980s, attacks on shipping in the Persian Gulf disrupted but did not halt oil flows. Iran has repeatedly threatened to close the strait during periods of geopolitical tension — most recently during the 2019-2020 escalation following the US killing of General Qasem Soleimani — but those threats never materialized into an actual blockade.
The closest historical analog for a supply disruption of this scale is the 1973 Arab Oil Embargo, which removed approximately 4.3 million barrels per day from global markets and caused US retail gasoline prices to roughly double within months. The 2022 Russian invasion of Ukraine removed approximately 2 to 3 million barrels per day of Russian crude from accessible markets and pushed WTI above $130 per barrel in March 2022 — the highest level since 2008. The current Hormuz disruption, if sustained, represents a potentially larger supply shock than either of those events in terms of raw volume affected.
For context, the US national average gas price peaked at $5.016 per gallon in June 2022 during the post-Ukraine price spike, according to AAA historical data. Analysts are now watching that $5.00 threshold closely as a potential ceiling — or floor — depending on how long the blockade persists.
Regional Breakdown
California remains the nation's most exposed state, with the California Energy Commission tracking statewide averages above $4.85 per gallon for regular unleaded. Los Angeles and San Francisco metro areas are running higher. Oregon and Washington State are tracking close behind, with averages near $4.55 to $4.70 per gallon, reflecting the West Coast's structural dependence on Pacific Rim and Middle East crude imports.
In the Midwest, Illinois is averaging near $3.78 per gallon, while Missouri and Indiana — states with lower fuel taxes and good pipeline access — are holding closer to $3.60. Michigan, which has seen refinery capacity constraints in recent years, is running slightly higher at approximately $3.82 per gallon.
The Gulf Coast corridor from Texas through Louisiana remains the nation's price floor. Texas statewide average is near $3.52 per gallon, benefiting from proximity to domestic production and the nation's largest refining complex. Florida, which imports significant volumes by sea, is tracking higher at approximately $3.88 per gallon.
The Northeast is under pressure. New York State is averaging near $4.15 per gallon, with New York City metro stations running above $4.30. Connecticut and Massachusetts are near $4.05 to $4.10 per gallon.
What Experts Are Saying
The EIA, in its most recent Short-Term Energy Outlook, had projected US regular gasoline retail prices averaging $3.30 per gallon for summer 2026 — a forecast that is now dramatically outdated given the Hormuz disruption. The agency is expected to release a revised outlook that could push summer average projections above $4.00 per gallon.
Goldman Sachs energy analysts have reportedly revised their Brent crude price forecast upward to a range of $110 to $125 per barrel if the blockade extends beyond 30 days, according to market reports. JPMorgan analysts have warned of potential $130-per-barrel Brent in a prolonged disruption scenario.
AAA spokesperson commentary has emphasized that US drivers should expect continued price volatility through at least July 2026, noting that the Strategic Petroleum Reserve — which the Biden administration drew down significantly in 2022 — has only partially been replenished, limiting the current administration's ability to deploy a comparable release to cushion prices.
The IEA has called an emergency meeting of member nations to coordinate a potential strategic reserve release, which could provide some near-term price relief if member countries agree to act collectively.
What Drivers Should Expect
The price trajectory for US drivers over the next four to eight weeks depends heavily on two variables: how long the Hormuz blockade persists, and whether the IEA coordinates a meaningful strategic petroleum reserve release. In a best-case scenario — blockade resolved within two to three weeks, SPR release announced — analysts suggest the national average price per gallon could stabilize in the $3.80 to $4.00 range before gradually retreating. In a prolonged disruption scenario extending beyond 60 days, the $5.00 national average threshold seen in June 2022 comes back into play.
For drivers making decisions right now, the calculus favors filling up sooner rather than later. Crude price increases typically take two to four weeks to fully pass through to retail pump prices, meaning today's $3.89 national average likely does not yet reflect the full $105-per-barrel crude cost. Prices at the pump could climb another 20 to 40 cents per gallon in the coming weeks before the market stabilizes.
Practical steps: Use GasBuddy or the AAA TripTik app to find the lowest prices per gallon within a reasonable driving radius. Wholesale club stations — Costco, Sam's Club, BJ's — are typically 15 to 25 cents per gallon below surrounding market prices and are worth the detour. Drivers with flexible schedules should note that Tuesday and Wednesday mornings historically show the lowest intra-week retail prices. Avoid premium grade unless your vehicle specifically requires it — the spread between regular and premium has widened to over 60 cents per gallon in many markets.
