US Strategic Petroleum Reserve Nears 3-Year Low as Iran War Strains Supply
The US Strategic Petroleum Reserve has dropped to levels not seen since mid-2023, as ongoing conflict in Iran tightens global oil supply and raises vulnerability of the Strait of Hormuz.

The US Strategic Petroleum Reserve (SPR) has fallen to its lowest level in three years, as the ongoing war with Iran depletes emergency crude stockpiles. The reserve, which was already drawn down significantly during the Russia-Ukraine conflict, now stands at levels last seen in mid-2023, according to Bloomberg.
The shrinking SPR underscores the growing fragility of global oil supply chains. With the Strait of Hormuz—a critical chokepoint for about 20% of the world's oil—remaining effectively closed due to hostilities, the buffer provided by strategic reserves becomes increasingly vital. For traders, this tightness in supply fundamentals supports crude prices, though the actual price impact will depend on how quickly alternative supply routes or production increases can materialize.

Looking ahead, market participants will focus on weekly US inventory reports and any diplomatic developments regarding the Strait of Hormuz. A prolonged closure could force further SPR draws, while a ceasefire might ease supply fears. The Biden administration's decision to release SPR barrels earlier has left limited room for additional emergency measures, making the next moves in the Iran conflict critical for oil markets.
