Summary
The article analyzes the depleted state of the U.S. Strategic Petroleum Reserve (SPR), which is at its lowest level since 1982, following major drawdowns in response to the Russia-Ukraine war. It discusses a hypothetical scenario of U.S./Israeli strikes on Iran leading to a closure of the Strait of Hormuz, highlighting how the diminished reserve limits Washington's ability to respond to such a major supply shock. The piece explains that refilling the SPR is a slow and complex process, further constraining its role as a market stabilizer.
Strategic Implication
A depleted US SPR reduces Washington's capacity to cushion global oil markets from major supply shocks originating in the MENA region, increasing price volatility risk for Gulf producers and global consumers.
