The oil market’s buffer has thinned after months of disruption around the Strait of Hormuz. Saudi Aramco CEO Amin Nasser says nearly 3 billion barrels of gross supply have been lost and that rebuilding inventories could take up to two years. Vitol CEO Russell Hardy warns that steady Middle Eastern exports are needed to keep markets balanced as winter approaches. 1

Supply lost and stocks drawn are different measures
Nasser’s estimate of nearly 3 billion barrels refers to gross oil supply lost during the disruption—not the amount removed from storage. Separately, more than 1 billion barrels have been drawn from stockpiles to cushion the shortfall. The figures describe different parts of the squeeze and should not be added together as a single measure of inventory depletion. 1

The distinction matters because commercial inventory totals do not show how much oil can actually reach the market. Nasser said fewer than 6 billion barrels of commercial inventories remain, with most not practically accessible; he estimated that less than 10% of reported inventories is readily available. 1

Why Western inventories make Gulf exports critical
Hardy said Western inventories are largely drained and that roughly 10 million to 14 million barrels a day need to leave the Middle East by ship to help keep the market in balance through winter. A recent increase in Gulf exports can support supply, but the market remains exposed if those flows falter. 7

That leaves the market with less room to absorb another disruption. Reuters reported that executives see dwindling accessible stocks as making the market more fragile and putting upward pressure on prices. Hardy also warned that refined-product tightness, including diesel, could continue into winter. 17

The G7 release can ease pressure, but cannot refill the buffer
G7 countries agreed to release about 100 million barrels of crude and diesel from strategic reserves. Nasser described the release as temporary relief, not a solution to the underlying supply-and-demand imbalance. It puts barrels into the market now, but does not itself restore the disrupted flows or replenish the stockpile buffer. 3
Rebuilding inventories could take up to two years
Even if the Strait of Hormuz fully reopens, Nasser said restoring inventories while continuing to meet demand could take up to two years. The timing is therefore conditional: normalizing shipments would help, but it would not mean that depleted stocks are immediately rebuilt. 1

The practical implication is continued sensitivity to supply interruptions. With limited accessible inventory, reliance on Gulf exports and tight diesel markets heading into winter, emergency releases may soften near-term pressure while leaving the broader market exposed. 3
