Are gas prices making your household finances worse off than a year ago?
CNN's election-night map showed gas price increases of 63 to 73 percent in multiple Kansas counties since February. The national average price for a gallon of gas is above $4, up about a dollar from a year ago.
Why it matters
Fuel costs are a direct household expense, and the rise in Kansas comes as voters head to the polls in a midterm election. The increases trace back to the U.S. and Israeli strikes on Iran and Iran's response of effectively blocking the Strait of Hormuz.
The figures come from CNN's county-level map displayed on election night, showing increases of 63 to 73 percent in multiple Kansas counties since February 2026, compared with a national average above $4 per gallon that is up about a dollar from a year ago. Whether these county increases will reverse remains unresolved, as no timeline has been set for the Iran conflict.

The details
Iran effectively blocked the Strait of Hormuz after the U.S. and Israel launched strikes on the country, choking off the world's oil supply. CNN's election-night map displayed the county-level gas price changes alongside live vote tallies, including the Kansas Senate race where Democrat Adam Hamilton led Republican incumbent Roger Marshall 57.8 percent to 40.2 percent.
Timeline

Oil Market Context
The current spike follows the pattern of supply-driven fuel price surges seen after Russia's 2022 invasion of Ukraine, when global supply disruptions pushed pump prices sharply higher. The Strait of Hormuz closure now places a similar strain on global oil flows, with Kansas counties showing some of the steepest local increases.
Kansas drivers facing steep pump prices may want to compare fuel costs across stations and track county-level changes as the Iran conflict develops. Households should budget for elevated fuel costs while the Strait of Hormuz remains constrained.
The takeaway
Fuel costs in Kansas are tied directly to events thousands of miles away, so tracking global supply disruptions can help explain price changes at the local pump. Planning for sustained higher gas prices is a practical step while the Iran situation is unresolved.
