The numbers at the pump are reflecting current global market conditions and geopolitical tensions. According to data from AAA, the national average of $4.300 is the highest level seen since late July 2022. For comparison, the average just one month ago was $3.990, and exactly one year ago, drivers were paying $3.183.
This surge corresponds with a rise in raw material costs and shifting availability. West Texas Intermediate (WTI) crude rose $6.95 in a single session to settle at $106.88 a barrel. As the cost of the underlying commodity increases, retail prices often reflect those changes in the broader market.
The supply-demand gap and WTI volatility
Looking at the fundamentals, the Energy Information Administration (EIA) reports a narrowing margin between how much gasoline Americans are using and how much is available. Last week, gasoline demand rose from 9.05 million barrels per day (b/d) to 9.10 million b/d. Simultaneously, the total domestic gasoline supply dropped from 228.4 million barrels to 222.3 million.
Production has also lagged, averaging 9.8 million barrels per day. This compression is further evidenced by crude oil inventories, which the EIA reports decreased by 6.2 million barrels from the previous week. While U.S. crude oil inventories sit at 459.5 million barrels—roughly 1% above the five-year average for this period—the rapid draw-down creates upward pressure on prices.
For the consumer, these macro shifts translate into immediate costs. In Chicago, drivers have seen prices climb $0.47 in the past week alone. The impact is most visible for those whose livelihoods depend on the road. David Adenekan, a veteran cab driver, noted that his fuel costs have doubled, stating, You have to work more, work more time to pay bills, pay the lease

The Strait of Hormuz and the Iranian blockade
The most volatile variable in the current pricing equation is the conflict involving Iran. Since the war began, the average price of gas has risen more than 47%. A central point of failure is the Strait of Hormuz; AAA reports there is currently no indication of when the Strait will reopen.
Adding to the supply anxiety is a U.S. Navy blockade of Iranian ports, which has been enforced since April 13. President Donald Trump has indicated he intends to maintain this pressure to prevent Iran from acquiring a nuclear weapon.

“Iran can’t let Iran have a nuclear weapon, and their economy is crashing. The power of the blockade is incredible. They’re not getting any money from oil, and hopefully it can be worked out very soon.” President Donald Trump
While the administration argues that the blockade is an effective tool, the markets are pricing in the risk of a long-term disruption. Officials have discussed the potential for prices to stabilize once the conflict concludes, though the ability of Iran to disrupt ship traffic through the Strait of Hormuz remains a significant concern for market stability.
The ongoing conflict continues to influence both diplomatic strategies and global energy markets. As the situation evolves, the intersection of military action and energy security remains a primary focus for policymakers and economic analysts monitoring the flow of oil.
Regional disparities and infrastructure shocks
Fuel costs are not distributed evenly across the U.S., with a stark divide between the West Coast and the South Central region. According to AAA, California is the most expensive market in the nation at $6.01 per gallon. Hawaii ($5.64) and Washington ($5.57) follow closely.
Conversely, Oklahoma offers the lowest prices in the country at $3.70 per gallon, followed by Kansas ($3.75) and Georgia ($3.75). This gap highlights the influence of regional refinery capacity and logistics.
Local infrastructure failures can exacerbate these trends. On the night of April 26, 2026, the BP Whiting refinery in Indiana experienced a brief loss of electric power. While BP stated that power was quickly restored and operations returned to normal, analysts suggest the incident added further pressure to prices in the Midwest. In Indiana and Illinois, prices saw a notable rise overnight following the event.

“We do not speculate on market pricing, nor do we set oil prices. On the night of April 26, 2026, some units within the Whiting Refinery experienced a brief loss of electric power. Power to those units was quickly restored and operations were returned to normal.” BP Whiting Refinery Statement
For some, the cost has reached a breaking point. Jackie Torres, an employee at Northwestern Hospital, reported that filling her SUV has climbed from $70 to closer to $100, noting that some premium fuel is reaching almost $7

The cost of switching to electric
As gasoline prices climb, the relative value of electric vehicles (EVs) has shifted, though electricity costs are not static. The national average for public EV charging rose by one cent this past week to 41 cents per kilowatt hour.
The regional disparity found in gasoline is mirrored in the electric market. West Virginia is the most expensive state for public charging at 53 cents per kilowatt hour, followed by Hawaii (51 cents) and Alaska (50 cents). The most affordable charging is found in Kansas (29 cents) and Missouri (31 cents).
Despite these incremental increases in electricity costs, the gap between the $4.300 national gas average and the cost of charging remains a primary driver for EV adoption. One driver noted that the switch has been very, very, very great as far as like saving on gas, for sure

What to watch
The immediate trajectory of fuel prices depends on two primary factors: the diplomatic resolution of the Iranian blockade and the upcoming Memorial Day travel surge. Because gasoline demand historically spikes in late May, any further reduction in domestic supply or continued closure of the Strait of Hormuz could lead to a meaningful increase in the national average.
Investors and drivers should monitor the next EIA report for changes in crude oil inventories and any formal updates regarding the reopening of shipping lanes in the Persian Gulf.
