Plummeting US Fuel Prices Could Trigger a Host of New Problems

The decline in fuel prices in the United States is beginning to give drivers a breather after months of supply disruptions. However, experts warn that the sharp drop could potentially bring a series of new problems for national economic stability. According to the latest estimates from AAA on Monday (30/6/2026), the national average petrol price has fallen to US$3.86 per gallon. While still far higher than before the conflict with Iran erupted on 28 February, this is a significant decrease from the four-year high of US$4.56 reached in May due to Tehran’s blockade of the Strait of Hormuz. Although tensions flared again last weekend with mutual attacks between the US and Iran, oil flows through the Strait of Hormuz have continued, putting downward pressure on global prices. Brent crude is now around US$73 per barrel, returning to pre-war levels after surpassing US$120 in late April. The Trump administration continues to push for further progress in the sector, as surveys show significant public dissatisfaction with household budget pressures and inflation handling. The US Department of Justice has even launched an investigation into alleged price gouging by major oil companies. The American Petroleum Institute (API) has denied the accusations. ‘Petrol prices do not move in lockstep with crude oil, especially during major global disruptions that still affect supply, refining, and inventories,’ said API spokesperson Bethany Williams. Beyond the good news for consumers, economists see hidden risks. Torsten Sløk, Chief Economist at Apollo Global Management, stated that cheaper petrol could trigger pent-up demand, thereby hampering progress in curbing inflation. ‘The market narrative is shifting from low oil prices mean low inflation to low oil prices mean more demand in an already hot economy and therefore higher inflation,’ Sløk wrote. He predicts this could force the Federal Reserve to raise interest rates again soon. Additionally, Abhi Gupta from Yale University’s Budget Lab highlighted the dual impact of the US being both a producer and consumer of oil. While lower prices help consumers, they can deter investment by fracking companies, especially in oil-producing states like Texas, New Mexico, and Oklahoma. Another issue is the potential slowdown of the transition to electric vehicles (EVs). When fuel prices surged, EV interest soared, reaching 26.1% of total car sales in May, according to a Goldman Sachs report. James Stock, a professor of political economy at Harvard University, warned that rapidly falling fuel prices could kill that momentum, leading consumers back to internal combustion engine vehicles and risking US automakers falling behind in the future global EV market.
