What Drives Gas Price Volatility and How itI Impacts US Households

Geopolitical tensions and disruptions to global energy supply often lead to higher gas prices at the pump. Amid the current conflict in Iran, oil prices have surged to above $100 per barrel for the first time since 2022. Although the US is a net exporter of oil, Americans are not immune to rising global oil prices that push gasoline costs higher.

Oil is a global market, so when prices rise, they increase across the board, including in countries like the US that export more oil than they import. However, despite global market pressures, US drivers actually pay among the lowest gas prices at the pump. The reason has less to do with domestic oil production and more to do with fuel taxes.


Europe has higher fuel taxes as governments prioritize energy conservation, which leads to higher electric vehicle market share and reduced overall auto ownership. By contrast, the US federal gasoline tax hasn’t increased since 1993. At the bottom end of the price spectrum are some of the Organization of the Petroleum Exporting Countries, where gasoline is sometimes priced below the input cost of crude. On the domestic front, gas prices can vary widely by state with differences driven by state‑level taxes.

Impact of gas prices on American consumers

There have been significant shifts in how reliant American consumers are on gasoline. For instance, gas prices currently account for only 1.7% of a typical household budget, an all-time low and less than half of its share three decades ago. This reflects improvements in fuel economy: A typical new light-duty vehicle gets 30 miles to the gallon, up from 20 miles per gallon three decades ago.
