Gasoline prices in South Carolina have jumped sharply over the past week, with the state average climbing to $3.63 per gallon, up 24 cents from the previous week. This surge reflects a broader national trend, with the U.S. average rising to $3.92 per gallon, also up about 24 cents in the past week. Analysts say global supply concerns and seasonal demand are driving the increases.

Why it matters

The rise in gas prices in South Carolina and across the country is putting a strain on consumers' budgets, particularly as the summer driving season approaches. This could impact consumer spending and the broader economy if prices continue to climb.

The details

According to data from GasBuddy, the increase of 24 cents per gallon in the last week leaves prices in South Carolina more than $1 higher than a month ago and nearly 91 cents higher than this time last year. Prices across the state vary widely, with the cheapest gas reported at $3.11 per gallon and the most expensive reaching $4.49, a difference of $1.38. Diesel prices are also climbing, with the national average reaching $5.22 per gallon — the highest level since late 2022.

What they’re saying

“Gas prices continued to rise nationwide over the last week as seasonal factors, combined with ongoing supply concerns tied to the continued disruption in the Strait of Hormuz, pushed both gasoline and diesel prices sharply higher.”

— Patrick De Haan, Head of Petroleum Analysis

What’s next

Analysts warn prices could continue rising in the near term, with the national average potentially reaching $4 per gallon for the first time in years.

The takeaway

The surge in gas prices in South Carolina and across the country is putting a significant strain on consumers' budgets, and the situation could worsen if prices continue to climb. This highlights the need for policymakers and industry leaders to address the underlying factors driving these increases, such as global supply concerns and seasonal demand shifts.
