Why U.S. Gas Prices Could Spike This Summer Despite a Recent Drop
Brussels, Tuesday, 16 June 2026.
Europe’s gasoline exports to the U.S. plunged to their lowest May levels since 2020, just as American inventories hit a 12-year June low. With refineries stretched thin and geopolitical tensions disrupting supply, experts warn the summer fuel crunch could push prices back above $4 per gallon—despite a brief dip following the U.S.-Iran peace deal.
Europe’s Shrinking Gasoline Lifeline to the U.S.
Europe’s gasoline exports to the United States averaged 1.63 million barrels per day (bpd) in May 2026, marking a sharp decline from 1.9 million bpd in May 2025. This represents the lowest May export level since 2020, according to data from Kpler [1]. The drop is particularly significant given that approximately 88% of these exports are destined for East Coast ports, which have historically relied on European imports to meet summer demand [1]. The second quarter of 2026 is projected to see European gasoline exports to the U.S. fall to 252,000 bpd, the lowest for that quarter since 2020 [1]. This reduction arrives as U.S. gasoline inventories sit at their lowest June levels since 2014, with just 215 million barrels available as of June 5, 2026 [2].
Refinery Constraints and Shifting Production Priorities
The decline in European exports is not occurring in isolation. U.S. refiners are operating near maximum capacity, limiting their ability to produce additional fuel [2]. This constraint is compounded by a strategic shift in production priorities. U.S. refiners have focused on maximizing diesel and jet fuel output, particularly as flows from the Middle East and Gulf (MEG) regions have been disrupted by ongoing geopolitical tensions [3]. European refineries, which are structurally configured for gasoline production, initially stepped in to fill the gap. In May 2026, European refiners exported 471,000 bpd of gasoline to the U.S., up from an average of 266,000 bpd in 2025 [3]. However, this surge in exports appears to have been a temporary measure, as European domestic demand has since risen, tightening the regional market [1].
Geopolitical Tensions and Supply Chain Disruptions
The reduction in transatlantic fuel shipments is occurring against a backdrop of persistent geopolitical risks. The closure of the Strait of Hormuz on February 28, 2026, following a U.S.-Israel attack on Iran, triggered the largest energy supply shock in history. The blockade disrupted the flow of 15 million barrels per day of crude oil and 5 million barrels per day of oil products, equivalent to 20% of global supply [4]. While a U.S.-Iran peace deal was announced on June 14, 2026, the impact of the disruption is expected to linger. Even with the Strait’s reopening, analysts warn that normalizing oil supply could take months, as restarting production and logistics pipelines is a complex and time-consuming process [1][4].
Price Volatility and Inflationary Pressures
The tightening fuel market has already begun to impact prices. On June 14, 2026, the U.S. average retail gasoline price dipped below $4 per gallon for the first time since mid-April 2026, following the announcement of the U.S.-Iran peace deal [1][2]. However, this price relief may be short-lived. Analysts project a global gasoline supply-demand deficit of 1 million bpd for May 2026 and 1.13 million bpd for June 2026, significantly exceeding the five-year averages of 489,000 bpd and 352,000 bpd, respectively [2]. Neil Crosby, an analyst at Sparta Commodities, cautioned, “Even if the politics goes perfectly, we are months away from normal supply-demand and now-oversold prices will eventually reflect that” [1][2]. Janiv Shah of Rystad Energy added, “The market is not structurally short, but the balance looks increasingly vulnerable heading into peak summer demand” [2].
Broader Economic Implications
The potential spike in gasoline prices carries significant economic implications. Higher fuel costs could reignite inflationary pressures, which have been a persistent concern for central banks in both the U.S. and Europe [1][2]. The Federal Reserve and the European Central Bank have been closely monitoring energy prices as part of their inflation-targeting frameworks. A sustained increase in gasoline prices could complicate monetary policy decisions, particularly if core inflation measures remain elevated [GPT]. Additionally, the disruption in gasoline supply is occurring alongside broader challenges in the oil market. The International Energy Agency (IEA) reported that global oil supply remains 12.8 million bpd below pre-war levels, with cumulative losses exceeding 1 billion barrels since the Strait of Hormuz closure [4].
Fertilizer Market Spillover Effects
The oil supply crisis is also reverberating through the global fertilizer market, further exacerbating inflationary pressures. The Strait of Hormuz disruption has impacted approximately one-third of global fertilizer suppliers, according to Kona Haque of the Economist Intelligence Unit (EIU) [5]. Haque cited UN Food and Agriculture Organization (FAO) data indicating that 1.07 billion people rely on food produced from imported nitrogen fertilizers [5]. The closure of the Strait has led to a spike in fertilizer prices, raising concerns about food security as many countries enter the planting season [5]. A joint statement from the World Trade Organization (WTO), International Monetary Fund (IMF), IEA, and World Bank on May 29, 2026, warned that the conflict’s effects are disproportionately affecting vulnerable countries through higher fuel and fertilizer prices, increased uncertainty, and risks to jobs and livelihoods [5].
Looking Ahead: A Fragile Market Balance
Industry experts warn that the gasoline market’s fragility could persist through the third quarter of 2026. The combination of reduced European exports, constrained refinery capacity, and heightened summer demand creates a precarious balance. While the U.S.-Iran peace deal has provided temporary relief, the underlying supply-demand dynamics suggest that prices could rebound sharply in the coming weeks [1][2]. Europe’s energy independence challenges are also coming into sharper focus. The continent’s reliance on oil, which accounted for 38% of its energy mix in 2024, has left it vulnerable to supply disruptions [4]. Emergency oil stocks in the Amsterdam-Rotterdam-Antwerp (ARA) region have fallen below 70% of the five-year average for jet fuel, though diesel and crude stocks remain stable [6]. The European Union’s requirement to maintain emergency oil stocks equivalent to at least 90 days of net imports or 60 days of consumption provides a buffer, but analysts caution that further untargeted fuel subsidies could exacerbate demand spikes during periods of scarcity [6].
