Global oil inventories are 509 million barrels below prewar levels—why recovering exports haven’t eased prices
By the end of September 2026, observed global oil inventories were 509 million barrels below their end February level—even as supply and Gulf exports recovered. The key distinction is between oil flowing now and oil available in storage: a slower inventory draw is still a draw, not a rebuilt reserve.

Recovering Gulf exports have not erased the oil market’s accumulated losses. The International Energy Agency (IEA) reported that observed global inventories fell by 10 million barrels in September, leaving them 509 million barrels below their end-February level. With less readily available oil in storage, renewed supply or shipping disruptions can still put pressure on prices. 9

Why higher exports have not rebuilt the buffer
Oil supply is a flow; inventories are the stock left over after supply and demand are balanced. More oil leaving the Gulf can improve current availability, but it does not automatically replace the barrels already drawn from storage.
The IEA estimated that global oil supply rose by 2.5 million barrels per day in September, to 102.3 million barrels per day. Yet observed inventories still edged down that month. On-land stocks fell by a further 113 million barrels, according to the agency’s October report. 9
Regional export data also show a recovery: Gulf crude exports averaged 24.6 million barrels per day in the week to October 18, above the prewar average, according to Kpler data reported by Al Jazeera. That weekly regional figure is not directly comparable with the IEA’s monthly estimate of total global supply. Together, however, the figures show that recovering shipments and depleted stocks can coexist. 11
The usable inventory matters more than the headline total
Not every barrel counted in storage is available to meet an immediate shortfall. Some stocks are difficult to access or are not being offered to the market. Reuters reported industry executives warning that less than 6 billion barrels of commercial inventories remained, with most not practically available to the global market. That is an attributed industry assessment—not a claim that storage tanks worldwide are nearly empty. 17
Vitol chief executive Russell Hardy also described Western inventories as having been drained of available barrels, according to Bloomberg. His remarks underline the distinction between total stocks and the smaller portion that can readily respond to a supply shock. 18
Slower draws are not the same as restocking
A decline that is smaller than the previous week’s decline still means inventories are shrinking. The latest EIA figures in the supplied reporting show U.S. commercial crude stocks fell by 1.9 million barrels in the week ended October 23, to 410.6 million barrels—about 4% below the five-year average for that time of year. 55
That U.S. weekly reading is not a measure of global inventories, but it illustrates why a slower draw does not by itself signal recovery. Energy Intelligence’s market analysis similarly describes continued stock draws and modest supply increases as insufficient to bring the market back into balance. 27
Why prices can rise while demand weakens
Oil prices respond not only to how much is being consumed today, but also to the risk that the next shipment may not arrive on time. When storage buffers are thin, the market has less room to absorb a disrupted route, delayed tanker, or renewed production loss.
Shipping risk around the Strait of Hormuz has added to concerns even as Gulf flows recovered. Al Jazeera reported that market analysts linked rising prices to depleted stocks, transport costs and the possibility of renewed hostilities. Brent closed at $116.72 on October 24, according to the supplied market report. 11

The IEA’s October outlook, as summarized in reporting, also projected a decline in oil demand in 2026. Weaker consumption can ease pressure, but it does not guarantee that inventories will start rising: that depends on whether available supply exceeds demand enough to replenish stocks. 12

The International Monetary Fund warned that falling oil and gas inventories could test the world’s ability to weather further energy disruptions. That warning concerns the market’s vulnerability to shocks, not a specific forecast for oil prices. 48
What Russell Hardy’s 14-million-barrel figure means
Hardy’s approximately 14 million barrels per day referred to shipments leaving the Middle East in the preceding seven to ten days: about 12 million barrels per day of crude and 2 million barrels per day of refined products. It was an export-flow figure, not an estimate of supply lost to the conflict. 19
The distinction matters because exports can help keep current supply moving while inventories remain depleted. The reported figure does not, on its own, establish how much flow would be needed through winter or support a precise oil-price target. 19
What to watch next
The clearest signs of a sustained recovery would be more than high export volumes: inventories would need to stop falling and begin rebuilding, while shipping and supply routes remain reliable. Conversely, another interruption could matter more in a market with a thinner readily accessible buffer. The IEA’s inventory figures, reported Gulf flows and weekly U.S. stock data each measure different parts of that picture; none alone settles whether the global cushion has been restored. 9
