U.S. Strategic Petroleum Reserve strained by aging infrastructure and repeated drawdowns

The United States’ Strategic Petroleum Reserve (SPR) is experiencing significant strain due to repeated oil drawdowns, aging infrastructure, and years of underinvestment. Equipment failures and deterioration of Gulf Coast salt caverns have reduced the reserve’s ability to withdraw and replenish oil, cutting the maximum withdrawal rate from 4.4 million barrels per day to about 2.7 million and the refill capacity from 785,000 to roughly 440,000 barrels per day.

Federal officials note that parts of the SPR are held together with temporary fixes, and repair projects face delays and cost overruns. While the SPR has been used by both the Biden and Trump administrations to release a combined 352 million barrels to stabilize soaring energy prices, experts warn that without substantial long‑term investment, its effectiveness in future energy emergencies could be compromised. The reserve remains a key tool for global oil‑market stability, especially amid ongoing U.S.–Iran tensions that threaten shipping through the Strait of Hormuz, and it continues to be coordinated with International Energy Agency members to limit price spikes.
