Global Oil Reserves at Critical Low, Executives Warn

The world's accessible oil reserves are critically low, a situation exacerbated by significant draws from stockpiles to mitigate supply disruptions caused by conflicts in the Middle East and Ukraine. Industry executives convened in London this week to discuss the increasingly fragile state of the global oil market, warning that the dwindling buffer could lead to upward pressure on prices.

Amin Nasser, CEO of Saudi Aramco, stated that less than six billion barrels of commercial oil inventories remain, with a substantial portion being practically unavailable. "The system is already straining," he noted during the Energy Intelligence Forum. Over one billion barrels have been released from commercial inventories this year alone, a move described as the "last major tool in the box."

Executives cautioned that the market's resilience cushion has become dangerously thin. Chevron CEO Mike Wirth commented that the depletion of market buffers has increased oil's price floor. The International Energy Agency is preparing to release 100 million barrels of crude and diesel to address rising diesel prices, though it remains unclear if this includes any remaining volumes from a March release. Nasser indicated that only about 10% or less of inventories are readily available, complicating efforts to supply the requested 100 million barrels.

World oil demand is currently estimated at approximately 102 million barrels per day, according to the IEA. The ongoing geopolitical instability, particularly in the Middle East and Ukraine, has significantly impacted supply chains, leading to the substantial depletion of strategic reserves.

Adding to concerns, the US Strategic Petroleum Reserve (SPR) holds the lowest stock levels recorded since October 1982, according to data from the Department of Energy. The challenges extend beyond crude oil, with natural gas inventories also depleted, making prices susceptible to sharp increases. Petronas CEO Tengku Muhammad Taufik warned that a harsh winter could lead to a severe gas market crisis in early 2027 if storage levels fall too low.

Experts predict that oil market turmoil could persist beyond the coming year, as replenishing inventories to adequate levels, alongside meeting global demand, may take several years. Factors such as operational constraints within storage facilities and pipeline systems, as well as government regulations mandating minimum stock levels, limit the immediate usability of all stored oil. Companies like Kuwait Petroleum Corporation are actively working to expand their domestic and overseas storage capacities in response to the market conditions. The reliance on seaborne oil exports to maintain market balance through the winter is critical, especially given the reduced inventory levels in Western nations.
