Chicago Gas Prices Surge Past $5: How the Iran War and Strait of Hormuz Closure Are Squeezing Illinois Drivers
The last time Chicago saw prices this high, Russia had just invaded Ukraine. Now, a conflict thousands of miles away is draining wallets across the Windy City.
Introduction: The $70 Fill-Up
Malik Allen pulled into the BP station at North Wells Street and West Chicago Avenue on Thursday morning with a half-empty tank and a sinking feeling in his stomach. The Moody Bible Institute student watched the numbers climb as fuel flowed into his sedan: $10… $25… $50… $70. When the pump finally clicked off, Allen had spent nearly three hours of minimum-wage work on a single tank of gas.
“There’s no escaping it,” he told WBEZ Chicago, standing beside his car at a station where regular gasoline was selling for $4.99 per gallon.
Allen’s experience has become increasingly common across Chicago and Illinois. As of Thursday, April 30, 2026, the average price for a gallon of regular gas in Chicago hit $5.01—a threshold not seen since August 2022. In some neighborhoods, like Avondale on the city’s Northwest Side, prices have soared even higher, with at least one BP station charging $5.39 per gallon.
The surge represents a stunning 33% increase from just one year ago, when Chicagoans were paying an average of $3.75 per gallon. But the most dramatic spike has come in recent weeks. Since February 28, when the United States and Israel launched a major attack on Iran, gas prices in the Chicago area have jumped by nearly 50%, according to data from AAA and GasBuddy.
This isn’t just an inconvenience for commuters. It’s an economic shockwave rippling through every corner of Illinois life, from the single mother calculating whether she can afford to drive to work, to the small business owner watching delivery costs eat into already thin margins, to the farmer wondering if planting season will be profitable.
And according to energy analysts, drivers shouldn’t expect relief anytime soon.
The Global Crisis Behind Local Pain
To understand why filling up in Chicago now costs more than a fast-food meal for two, you have to look 6,700 miles away to a narrow waterway in the Middle East.
The Strait of Hormuz: The World’s Oil Jugular
The Strait of Hormuz, a 21-mile-wide channel connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea, is arguably the most strategically important passage in the global economy. Approximately one-fifth of the world’s daily oil consumption—about 20 million barrels—passes through this narrow chokepoint.
When Iran closed the strait following the February 28 attack, it didn’t just disrupt regional shipping. It sent shockwaves through global energy markets that continue to reverberate in Chicago gas stations.
“There’s never been anything in the history of the oil market that really is at the same scale as this,” said Sam Ori, executive director of the University of Chicago’s Institute for Climate and Sustainable Growth. “You’re talking about a fifth of the world’s oil supplies being disrupted. There are some alternative routes, but in the best case, you’re still talking about a supply disruption of 10 to 15 million barrels a day.”
To put that in perspective, the world consumes roughly 100 million barrels of oil daily. Losing 10-15% of global supply overnight is unprecedented in modern energy history. Even the 1973 Arab oil embargo, which shocked American consumers and reshaped foreign policy for a generation, didn’t remove this much supply from the market this quickly.
Why Iran Controls This Critical Passage
Iran’s geographic position gives it enormous leverage over global energy markets. The country’s coastline includes both the Persian Gulf and the Gulf of Oman, putting Iranian military assets within striking distance of any vessel attempting to transit the strait.
While international law designates the Strait of Hormuz as an international waterway, Iran has long maintained that it can control passage through its territorial waters. Military analysts suggest that Iran could effectively block the strait using mines, anti-ship missiles, or swarms of fast attack boats—making any passage extremely risky for commercial shipping.
The February closure came after weeks of escalating tensions. The U.S.-Israeli attack on February 28 targeted Iranian nuclear facilities and military installations, prompting Tehran to retaliate by shutting down the strait and declaring that no vessels associated with countries supporting Israel would be permitted passage.
Stalled Negotiations, Uncertain Future
As of early May, negotiations to end the war between the United States and Iran have stalled. Diplomatic efforts led by European intermediaries have failed to produce a ceasefire agreement, and Iranian officials have indicated they will not reopen the strait until what they call “aggression against the Iranian nation” ceases.
This uncertainty is precisely what energy markets hate most. Oil prices are determined not just by current supply and demand, but by expectations about future availability. With no clear end to the crisis in sight, traders have bid up oil prices in anticipation of prolonged scarcity.
“It’s been a tremendous jump in Illinois, Indiana, Ohio and Michigan,” said Patrick De Haan, head of petroleum analysis at GasBuddy, a fuel price tracking service. “What we’re seeing is the market pricing in a significant risk premium because of the uncertainty around when—or if—the strait will reopen.”
Chicago’s Perfect Storm: Why Illinois Pays More
While gas prices have risen nationwide, Chicago and Illinois have been hit particularly hard. The $5.01 average in Chicago is significantly higher than the national average of $4.30, and the gap has widened in recent weeks.
Higher Taxes, Higher Prices
Illinois has some of the highest gas taxes in the nation. The state imposes a motor fuel tax of $0.392 per gallon on gasoline, which increased from $0.38 in 2023 as part of automatic inflation adjustments. On top of that, the Regional Transportation Authority (RTA) adds another $0.06 per gallon to fund public transit in the Chicago area.
Cook County, where Chicago is located, layers on additional taxes, including a $0.06 per gallon county motor fuel tax. And the city of Chicago itself imposes yet another $0.08 per gallon city motor fuel tax.
Add federal taxes of $0.184 per gallon, and Chicago drivers pay approximately $0.78 per gallon in taxes alone—before accounting for the actual cost of the fuel, refining, and distribution.
The Reformulated Fuel Requirement
Chicago also faces unique environmental regulations that increase costs. During summer months, the city requires reformulated gasoline (RFG), a special blend designed to reduce smog-forming emissions. This specialized fuel is more expensive to produce and fewer refineries make it, reducing supply and driving up prices.
The switch from winter to summer blend, which typically happens in May, adds another seasonal price pressure that is colliding with the Iran crisis this year.
Geographic Vulnerability
Chicago’s location in the Midwest, far from the Gulf Coast refineries that process much of America’s gasoline, makes it dependent on pipelines and regional refineries. When national supply tightens, as it has with the Strait of Hormuz closure, inland markets feel the pinch more acutely than coastal cities with direct access to ports.
The BP Whiting refinery in northwest Indiana, which supplies much of the Chicago area, has reportedly been operating at reduced capacity due to maintenance issues—a problem that becomes critical when supply chains are already strained.
The Real Cost: How $5 Gas Changes Lives
Behind the statistics are millions of individual stories of adjustment, sacrifice, and stress. For many Illinois families, the jump from $3.75 to $5.01 per gallon isn’t an abstract economic indicator—it’s a daily calculation with real consequences.
The Commuting Crisis
The average Chicago driver travels approximately 12,000 miles per year. At 25 miles per gallon, that’s 480 gallons of gas annually. At $3.75 per gallon, annual fuel costs were $1,800. At $5.01, those same miles cost $2,405—a $605 annual increase.
For minimum-wage workers, that’s more than 80 hours of additional work just to pay for the same commute. For families already struggling with inflation in housing, groceries, and healthcare, it’s a burden that forces difficult choices.
Transit agencies have reported increased ridership as some commuters abandon their cars, but Chicago’s public transportation system, while extensive, doesn’t reach all job centers or suburbs. For workers in manufacturing, logistics, and other sectors concentrated in areas with limited transit access, driving remains essential.
The Gig Economy Squeeze
Rideshare drivers for Uber and Lyft, delivery workers for DoorDash and Instacart, and independent contractors of all types face a particularly acute crisis. These workers typically use their own vehicles and pay for their own fuel, meaning every price increase comes directly out of their earnings.
Industry forums have seen a surge in complaints from drivers considering leaving the platforms. Some have reported that after accounting for gas costs, vehicle depreciation, and maintenance, their effective hourly wage has dropped below minimum wage in recent weeks.
Uber and Lyft have implemented fuel surcharges in some markets, but drivers report these temporary fees don’t fully offset the cost increases—and they’re typically removed once prices stabilize, even if that stabilization happens at a higher level than before the spike.
Small Business Pressure
For small businesses, especially those dependent on delivery or service calls, the fuel price surge is another margin squeeze in an already challenging economic environment.
Plumbers, electricians, HVAC technicians, and other tradespeople who make house calls have few options to reduce fuel consumption. They can’t telecommute, and they can’t raise prices instantly without losing customers. Many are absorbing the costs themselves, hoping the crisis is temporary.
Restaurants that rely on delivery services are seeing their fees increase as drivers demand more compensation. Some have reduced their delivery radius or eliminated delivery entirely, cutting off a revenue stream that became critical during the pandemic.
The Rural Divide
While Chicago’s $5.01 average makes headlines, rural Illinois faces an even more severe burden. In areas with no public transit and greater distances between homes, jobs, and services, residents have fewer options to reduce driving.
Farmers, who need diesel for tractors and trucks, are watching their planting season costs soar. Diesel prices have risen even more sharply than gasoline, with implications for food prices that will be felt months from now when crops reach market.
Diesel: The Hidden Crisis
While consumers focus on gasoline prices at the pump, energy experts say the diesel situation may be more concerning for the broader economy.
“Gasoline prices are what you and I are going to complain about,” said GasBuddy’s Patrick De Haan, “but at the end of the day, it’s the price of diesel that is far more impactful to the broader U.S. economy. Everything in this economy moves with diesel.”
Seventy percent of the oil consumed daily in the U.S. goes to the transportation sector, according to Sam Ori at the University of Chicago. Diesel powers the trucks that deliver groceries to supermarkets, the trains that carry coal to power plants, the ships that bring imports to American ports, and the farm equipment that produces the nation’s food.
When diesel prices spike, those costs are passed along the entire supply chain. Grocery stores pay more for delivery and raise prices. Manufacturers pay more for raw materials and components. Ultimately, virtually every product and service in the economy becomes more expensive.
Diesel prices have risen even more dramatically than gasoline, with some regions seeing prices above $6 per gallon. The reasons are similar to gasoline—reduced supply from the Strait of Hormuz closure, increased demand as the economy recovers—but diesel markets are tighter to begin with, with less spare refining capacity.
The result is a double squeeze: consumers pay more directly at the pump, and then pay more indirectly through higher prices for everything they buy.
Historical Context: We’ve Been Here Before
For Chicagoans old enough to remember, today’s prices may trigger memories of earlier energy crises. Understanding these historical precedents helps frame the current situation—and offers clues about what might come next.
1973: The Arab Oil Embargo
The first modern energy crisis began in October 1973, when Arab members of OPEC imposed an embargo on oil exports to the United States and other countries supporting Israel in the Yom Kippur War. Gas prices quadrupled, and Americans faced long lines at stations that often ran out of fuel entirely.
The crisis fundamentally reshaped American energy policy, leading to the creation of the Strategic Petroleum Reserve, fuel efficiency standards for vehicles, and a broader awareness of energy security issues.
1979: The Iranian Revolution
The second oil shock came in 1979, when the Iranian Revolution disrupted production in one of the world’s major oil-exporting nations. Prices doubled again, and the United States experienced another wave of inflation and economic disruption.
2008: The Great Recession Spike
Oil prices hit record highs in July 2008, with crude oil reaching $147 per barrel. Unlike the earlier crises, this spike wasn’t caused by supply disruption but by surging demand from developing economies, particularly China and India. The high prices contributed to the economic stresses that preceded the Great Recession.
2022: Russia Invades Ukraine
The most recent precedent came in February 2022, when Russia’s invasion of Ukraine disrupted global energy markets. Prices spiked above $5 per gallon in Chicago and many other cities before gradually declining as alternative supplies were arranged.
That crisis, however, primarily affected natural gas and European markets, with the U.S. able to increase domestic production and exports to partially offset disruptions. The current Strait of Hormuz crisis is different—affecting global oil supplies at their source.
What History Teaches Us
Each of these crises eventually resolved, but they all had lasting impacts. The 1970s shocks permanently altered American energy policy and vehicle preferences. The 2008 spike accelerated the shift toward electric vehicles and renewable energy. The 2022 crisis highlighted Europe’s dependence on Russian gas and prompted a rapid shift toward alternative sources.
The current crisis may similarly accelerate trends already underway. Electric vehicle sales, which had slowed somewhat after initial early adopter enthusiasm, could see renewed interest as consumers seek to escape volatile gas prices. Investment in renewable energy and domestic oil production may increase. And policymakers may finally take serious action on long-discussed ideas like expanded public transit and vehicle efficiency standards.
Looking Ahead: Will Prices Keep Rising?
Energy analysts are divided on where prices go from here, but most agree that relief is unlikely in the immediate future.
The Bull Case: Prices Could Go Higher
If the Strait of Hormuz remains closed through the summer driving season, when American demand typically peaks, prices could rise significantly higher than current levels. Some analysts have suggested $6 per gallon is possible in Chicago if the crisis persists into July and August.
Other factors could push prices higher:
- Hurricane season, which can disrupt Gulf Coast refineries
- Continued economic recovery increasing demand
- Further deterioration in Middle East stability
- Refinery capacity constraints as facilities struggle to meet specialized summer blend requirements
The Bear Case: Relief Could Come
On the other hand, several factors could bring prices down:
- Successful diplomatic resolution of the Iran crisis and reopening of the strait
- Release of strategic petroleum reserves by the U.S. and other countries
- Economic slowdown reducing demand
- Increased production from non-Middle East sources
- Completion of refinery maintenance and restoration of full capacity
The Biden administration has reportedly considered releasing oil from the Strategic Petroleum Reserve, a move that could temporarily lower prices but would deplete reserves intended for genuine emergencies.
The Most Likely Scenario
Most analysts expect prices to remain elevated through the summer, even if diplomatic progress is made. Once supply disruptions occur, it takes time for markets to stabilize. Refineries need to adjust operations, distributors need to rebuild inventories, and consumers need to modify behavior.
“Even if the strait reopened tomorrow, which seems unlikely, we’d still be looking at elevated prices for several months,” said De Haan. “The market is pricing in uncertainty, and uncertainty doesn’t resolve instantly.”
How Illinois Drivers Can Cope
While individual drivers can’t solve the Strait of Hormuz crisis, there are strategies to minimize the financial impact of high gas prices.
Driving Techniques That Save Fuel
The U.S. Department of Energy recommends several practices that can improve fuel economy by 10-40%:
- Aggressive driving (rapid acceleration and braking) can lower gas mileage by 15-30% at highway speeds
- Observe speed limits—gas mileage usually decreases rapidly at speeds above 50 mph
- Avoid excessive idling—turn off your engine when parked
- Use cruise control on highways to maintain constant speed
- Remove excess weight from your vehicle
- Avoid rooftop cargo boxes that increase wind resistance
Vehicle Maintenance Matters
Proper maintenance can significantly improve fuel economy:
- Keep tires properly inflated (under-inflated tires can reduce mileage by 0.2% for every 1 PSI drop)
- Use the manufacturer’s recommended motor oil
- Replace dirty air filters
- Address check engine lights promptly
- Consider a tune-up if your vehicle is due
Alternative Transportation
When possible, alternatives to driving can provide significant savings:
- Public transit, where available
- Carpooling with coworkers or neighbors
- Biking for short trips
- Walking for errands under a mile
- Combining trips to reduce total miles driven
Strategic Fuel Purchasing
Several apps and services can help find the cheapest gas in your area:
- GasBuddy shows prices at nearby stations
- Waze includes gas price information
- Some grocery store loyalty programs offer fuel discounts
- Warehouse clubs like Costco often sell gas at lower prices
The Political Response
High gas prices inevitably become political, and Illinois politicians are already responding to constituent concerns.
State-Level Actions
Governor J.B. Pritzker has called for federal action to address the crisis, including pressure on Iran to reopen the Strait of Hormuz and consideration of strategic petroleum reserve releases. However, state officials have limited direct tools to affect global oil markets.
Some state legislators have proposed temporarily suspending Illinois’ motor fuel tax, similar to measures taken by some other states during previous price spikes. However, such a suspension would cost the state hundreds of millions in transportation funding at a time when infrastructure needs remain significant.
Federal Responses
The Biden administration faces a difficult balancing act. Releasing strategic reserves could lower prices temporarily but would deplete emergency stocks. Negotiating with Iran carries foreign policy risks and could be seen as rewarding aggression. And pressuring domestic oil companies to increase production conflicts with climate goals.
Republicans have criticized the administration’s energy policies, arguing that restrictions on domestic drilling and pipeline construction have made the U.S. more vulnerable to global supply disruptions. Democrats counter that the crisis proves the need to accelerate the transition away from fossil fuels entirely.
Long-Term Policy Debates
The current crisis is likely to reignite long-standing debates about American energy policy:
- Should the U.S. maintain or increase domestic oil production to reduce import dependence?
- Should fuel taxes be adjusted during price spikes, or does that encourage consumption?
- Should more funding go to public transit and alternative transportation?
- Should vehicle efficiency standards be strengthened or relaxed?
- Should the government subsidize electric vehicle adoption to accelerate the transition?
These questions have no easy answers, and the political divide on energy policy remains wide. But the pain at the pump may create pressure for at least temporary cooperation on measures to provide immediate relief.
Conclusion: A New Normal?
As Malik Allen drove away from that BP station, $70 lighter but with a full tank, he joined millions of Illinois residents adapting to a new reality. The era of cheap, abundant gasoline that shaped American life for decades may be drawing to a close, replaced by a more volatile and uncertain energy future.
The Strait of Hormuz crisis won’t last forever. Eventually, diplomatic pressure, economic necessity, or military action will reopen the waterway, and oil markets will stabilize. But the vulnerabilities it has exposed—the world’s dependence on a single chokepoint, the limited spare capacity in global oil markets, the speed with which localized conflicts become global economic shocks—will remain.
For Chicago and Illinois, this crisis is a wake-up call. The region’s economy, built on manufacturing, logistics, and transportation, is uniquely exposed to fuel price volatility. The daily commutes, suburban lifestyles, and car-dependent development patterns that define modern American life assume affordable energy.
Whether that assumption holds true in the decades ahead may determine not just how much Chicagoans pay at the pump, but how they live, work, and move around their city.
In the meantime, drivers like Malik Allen will keep filling up, keep paying more, and keep hoping that relief comes soon. Because as he said, standing beside his sedan on a Thursday morning in Chicago: “There’s no escaping it.”
