Gas prices in Texas have risen sharply in recent weeks, with the average price for a gallon of regular unleaded now at $3.26 statewide - a 39-cent increase from a week ago. In San Antonio, prices have jumped 26 cents to $3.17 per gallon, while premium fuel is now $4.01 per gallon. This is part of a broader trend across major Texas cities, with El Paso seeing the highest prices and Dallas experiencing the biggest week-over-week increase.

Why it matters

The rise in gas prices is being driven by the ongoing conflict in Iran, which is impacting global oil supplies and refining capacity. This is putting a strain on Texas drivers, especially those planning Spring Break road trips. The price hikes come at a time when many households are still recovering from the economic impacts of the pandemic.
