Gas prices are rising again nationwide, with the average currently at $3.63 per gallon, according to AAA. Experts attribute the unexpected increase in last month's inflation to rising gas prices and housing costs, which drove over half of the 3.5% year-over-year rise in the consumer price index. Summer gasoline and refinery maintenance are factors, while geopolitics also impact oil prices. Global market uncertainty stems from events like the Ukraine war and Mideast tensions.
