WEX^® (NYSE: WEX), a global leader in intelligent payment solutions, today announced the launch of the WEX Index^®: The fleet and mobility spend report. Pairing WEX proprietary transaction data with the company’s expertise, the analysis shows how commercial fleets managed the 2026 fuel price surge, including where and what type of fuel they bought. The report covers January through September 2026.

The new WEX Index®, built from real transaction data across WEX’s 600,000+ mobility customers, benchmarks fleet fuel spend, fraud risk, and EV readiness to show fleets where they stand and where they may be leaving money on the table.

WEX data revealed the average U.S. fuel price rose approximately 43% in the third quarter of 2026 compared to a year earlier, increasing from $3.38 to $4.85 per gallon, while gallons pumped stayed essentially flat. The WEX Index shows that fleets absorbed those costs and kept moving anyway. The report examines purchasing decisions leaders can review, including where drivers fuel and which grade they buy, establishing a baseline for fleets to adapt to the challenges of higher fuel prices.

Key findings from The WEX Index include:

• Gallons pumped held steady as prices soared. Average U.S. fuel prices rose while gallons purchased remained essentially flat.
• Some fill-ups cost more than they should. 38.1% of North American commercial fleets paid more than the local WEX Fuel Price Index (FPI) benchmark.
• Premium fuel is a hidden cost. Analysis shows premium fuel accounts for 7.6% of transactions, at an average cost gap of $0.78 per gallon, representing up to $86.9 million in potential savings for vehicles that don’t require that grade.
• External threats are growing too. Industry numbers show phishing attacks increased 1,265% since Q4 2022, when generative AI tools became widely available. Additionally, 81.4% of fleets with five or more drivers had at least one driver spending more on fuel than their fleet average, which is a reason for fleets to closely review transactions.
• EV decisions are best made vehicle by vehicle. In an analysis of 8,798 vehicles, 27% were recommended for EV replacement. As a modeled average, each replacement would save $16,595, or 15% in costs, over the vehicle’s service life.

“Fleets can’t control the price of fuel, but they can control how they respond to it,” said Melissa Smith, chief executive officer and president of WEX. “The WEX Index gives the mobility sector a fixed point of reference built from real transactions by real fleets. With that baseline, fleet managers can see how they compare to their peers, spot risk earlier, and make smarter decisions about everything from fueling habits to building a mixed-energy fleet.”

The WEX Index outlines five practices fleets can use to put the data to work: Set a baseline, compare fueling against the local benchmark, focus on the numbers that matter, assess mixed-energy options, and revisit the baseline as conditions change. It is intended as the first in a series, with future editions comparing against this baseline so fleets can track their own progress against industry figures.

To bring the Index’s findings to a broader business audience, WEX published an article with Bloomberg Media Studios. The piece looks at how fleets are managing a historic fuel price shock with little room to cut consumption, and how choices about where drivers fuel and which grade they buy can uncover savings.
