US crude oil reserves have fallen sharply as refinery activity rises and disruptions in Middle Eastern oil flows increase pressure on global energy markets. Analysts warn that declining stockpiles could reduce Washington’s ability to respond to future supply shocks.
US Crude Stocks Drop as Refineries Increase Output
Commercial crude oil inventories in the United States fell by 7.2 million barrels last week, according to government data. The Strategic Petroleum Reserve (SPR) also declined by 3.8 million barrels, as refineries used more crude to produce fuels such as gasoline, diesel and jet fuel.
US refineries are currently operating at around 97% of capacity, with some facilities in the Midwest reaching full capacity. The increase in refinery activity comes as energy companies seek to supply markets facing uncertainty after renewed hostilities involving Iran disrupted oil flows from the Middle East.
Middle East Supply Disruptions Put Pressure on Markets
Oil shipments through the Strait of Hormuz, one of the world’s most important energy routes, have been affected by the escalation of tensions between the US and Iran. The disruption has raised concerns among countries in Asia and Europe that rely heavily on Middle Eastern energy supplies.
Analysts said the decline in US inventories was larger than expected and could reduce the country’s ability to act as a backup supplier during future disruptions. Matt Smith, an analyst at Kpler, said US crude inventories, including commercial reserves and the Strategic Petroleum Reserve, have fallen by almost 20% since early April.
He noted that the US has played a major role in stabilising global oil markets through additional exports and releases from emergency reserves.
Strategic Petroleum Reserve Reaches Lowest Level in More Than 40 Years
The Strategic Petroleum Reserve has fallen to 307.7 million barrels, its lowest level in more than four decades. Industry analysts estimate that the reserve’s operational minimum is between 180 million and 200 million barrels. Falling below that range could create technical difficulties linked to infrastructure and pipeline operations.
Rory Johnston, founder of Commodity Context, described current crude and gasoline inventories as being at “precariously low” levels.
Lower Reserves Increase Exposure to Future Supply Shocks
The decline in US oil reserves has increased concerns about how quickly the country could respond to another major disruption. The Strategic Petroleum Reserve was designed to provide a buffer during emergencies, but continued withdrawals have reduced the available supply.
Analysts warn that if reserves continue falling towards operational limits, future disruptions could place stronger pressure on oil prices. The situation highlights the challenges facing global energy markets as geopolitical tensions, supply routes and national reserves continue to influence fuel costs.
