The U.S. Strategic Petroleum Reserve saw its largest weekly drain in history during May 2026 to stabilize domestic oil supplies [1].
These record releases occur despite previous promises by President Donald Trump (R-US) to refill the emergency reserves. The accelerated drawdown highlights the tension between long-term energy security and the immediate need to mitigate price shocks caused by geopolitical instability.
According to data from mid-May, the reserve experienced a drawdown of 8.6 million barrels for the week ending May 8 [2]. This was followed by a record-breaking release of 9.92 million barrels for the week ending May 15 [1], [2]. Together, these two weeks resulted in a total drawdown of approximately 18.5 million barrels [2].
The administration has utilized these releases to address disruptions caused by the war in Iran [3]. This action falls under a declared national energy emergency intended to prevent severe shortages and price volatility in the U.S. market [3], [4].
The current pace of releases exceeds the rate of drawdown seen under the previous administration [1]. This acceleration comes at a time when the reserves were already depleted; as of early 2025, the SPR was reported to be less than 60% full [5].
These operations are centered at SPR facilities located in Texas and Louisiana [3], [4]. The government continues to manage these assets to balance immediate market needs with the goal of eventually restoring the reserve's capacity.
“The U.S. Strategic Petroleum Reserve saw its largest weekly drain in history during May 2026.”
The record-breaking depletion of the SPR indicates that the U.S. is prioritizing immediate price stability over strategic longevity. By drawing down reserves at a faster rate than the previous administration, the current government is utilizing its remaining emergency cushion to offset the impact of the conflict in Iran. However, with capacity already below 60% as of early 2025, the ability of the U.S. to respond to future energy shocks may be significantly diminished until a comprehensive refill strategy is implemented.
