In a notable shift in consumer behavior, drivers across the United States are increasingly turning to Costco and Walmart for discounted fuel, often making special trips to these locations for the first time. This trend is being largely driven by a significant rise in gas prices exacerbated by the ongoing conflict in Iran, which has started to affect global oil supplies.
Costco has reported record-breaking fuel sales, particularly between April and mid-May, according to CEO Ron Vachris. To accommodate the surge in demand, many Costco gas stations have required multiple daily deliveries of gasoline. Consumers are not only seeking cheaper gas but are also adjusting their refueling habits by filling up more frequently but with smaller amounts. Gary Millerchip, Costco’s finance chief, noted that members are now filling up in between their usual gas tank cycles, motivated by uncertainty over future fuel prices.
Similarly, Walmart has observed a change in customer behavior, with many drivers now refueling with less than ten gallons per visit— a trend not seen since last year. John David Rainey, Walmart’s Chief Financial Officer, remarked on the contrasting spending patterns between high-income customers, who continue to spend confidently, and lower-income consumers, who are increasingly budget-conscious amid rising fuel costs.
The discount gas chain Murphy USA has also reported an uptick in first-time customers and a return of previous shoppers. CEO Mindy West stated that consumers are changing their shopping behaviors to become more value-oriented, indicating a broader trend of seeking financial savings amidst rising fuel prices. The average price of regular gas in the U.S. reached $4.39 per gallon, reflecting an increase of $1.22 compared to the same time last year. This surge has caused many Americans to allocate a larger portion of their income to fuel.
Federal data shows a substantial 21% increase in gas station spending in April compared to the previous year, underscoring the growing financial strain on consumers. With oil supplies dwindling, analysts are warning that gas prices could rise even further in the coming weeks. The blockage of oil tankers in the Strait of Hormuz, a critical route for global fuel shipments, is a primary factor contributing to these anticipated price hikes.
Concerns voiced at an investment conference by an ExxonMobil executive suggested that gasoline prices could see dramatic increases shortly, as oil reserves reach critically low levels. Executives from both Walmart and Costco pointed out that elevated fuel prices are likely to contribute to higher costs on grocery store shelves. Increased transportation expenses for manufacturers and retailers, along with rising fertilizer costs—also affected by the situation in the Strait of Hormuz—could exacerbate the financial burdens on consumers.
As the situation develops, the changing dynamics of gas purchasing behavior and the implications for household finances remain a focal point of concern for many across the nation.
