Cushing oil hub sinks toward critical low as wartime demand drains US reserves, industry warns of price shock
Crude inventories at the Cushing hub in Oklahoma have slumped to 21.6 million barrels, only marginally above the 20-million-barrel operational minimum, as record demand driven by the Iran war empties US storage faster than producers can refill it. Two senior industry figures say a sudden price surge could hit within weeks.
Storage tanks at Cushing, Oklahoma — the delivery point for West Texas Intermediate crude and a linchpin of the US oil network — are draining at a pace that has put the global market on edge. According to the US Energy Information Administration (EIA), current stocks stand at 21.6 million barrels. The hub normally holds about 40 million barrels and has a nameplate capacity of 75 million. Once reserves fall below 20 million, the tanks contain mostly unusable sludge, making it impossible to maintain pipeline pressure or keep refiners supplied.
War-driven demand empties the tanks
The United States has become the back-up supplier for regions that typically rely on Middle Eastern crude, a role that deepened during the war with Iran. US oil is flowing out of Cushing faster than domestic producers can replenish it. David Oxley, chief commodities economist at Capital Economics, said that inventories across the richest countries are shrinking by 6.3 million barrels a day and total just 2.6 billion barrels — about 100 million barrels above the operational stress level.
That is just 100 million barrels above the operational stress level.
The danger zone
Analysts warn the global market could enter a danger zone within a month. At current draw rates, even a minor disruption — a pipeline leak, a refinery fire, or adverse weather — could trigger panic and make prices extraordinarily volatile. The physical limit of the system means that oil cannot be consumed down to the last drop; below a certain threshold, pipelines lose pressure and refineries cannot deliver product to customers.

History repeating
The pattern is familiar. Every time Cushing inventories approached operational minimums — in 2008, 2022, and 2023 — fuel prices hit record highs. CNN noted that the same sequence could play out again in a matter of weeks. Mike Sommers, president of the American Petroleum Institute, made the urgency plain.
Right now we are sounding the alarm.
Neil Chapman, vice president of ExxonMobil, speaking at a conference in New York at the end of May, described the inventory levels as “unprecedented” and said they are reaching a critical point.
When you reach that point, prices will spike.
Where prices could go
Oxley cautioned that crude could easily break above $90 a barrel today and move toward $140–160 in the coming months, while gas could surpass $5 if the Strait of Hormuz is not fully reopened. The combination of constrained supply and fragile logistics is amplifying fears that a price shock is not a distant risk but an imminent one.
