IEA member countries slow emergency oil reserve releases in July as global inventories drop sharply

July wasn’t a quiet month for global oil markets—even if the headline numbers made it look that way. IEA member countries released just 26 million barrels of emergency oil stocks, less than a third of what they drew down in May. Crude availability had improved across parts of Asia Pacific, easing some of the pressure. Cumulative releases since March 11 now sit at 300 million barrels, out of a coordinated 400-million-barrel commitment. But here’s the catch: global oil inventories still dropped hard, falling below 7.9 billion barrels by month’s end.

Emergency withdrawals drop to their lowest monthly pace since the coordinated action began

July’s 26 million barrels represent a steep deceleration. Government stock draws averaged 750,000 barrels per day—down from 1.5 million b/d in June and 2.5 million b/d in May. A halving, then a halving again, in just two months.

The 300-million-barrel cumulative total puts the effort three-quarters through the announced plan—which also means more than 100 million barrels of committed supply still hasn’t reached the market. That’s not a small footnote. It’s a substantial volume still sitting on the sidelines, and its absence is being felt.

July’s decline partly reversed that—meaning some of what looked like a build in June was temporary, and its unwinding in July amplified the apparent drop.

Improved crude availability in Asia Pacific and US SPR cuts drive the slowdown

The biggest pullback came from Asia Oceania, where member countries released just 4 million barrels in July, down from 8 million in June and dramatically lower than the 44 million released in May. The IEA pointed directly to improved crude supply availability in Japan and Korea. When the underlying problem eases, the urgency to tap emergency stocks fades—that’s the logic working as intended.

The US also pulled back. Withdrawals from the Strategic Petroleum Reserve came in at 17 million barrels, roughly half of June’s volume. Since the SPR is the single largest contributor to the coordinated action, even a partial slowdown there moves the overall numbers significantly. A quieter Asia Oceania and a more restrained US together explain most of why July’s total landed so far below previous months.

Global oil inventories fall sharply as Strait of Hormuz shipping constraints tighten

Here’s where things get complicated. Even as emergency releases slowed, global inventories didn’t hold steady—they fell hard. Total observed inventories dropped by 69 million barrels in July, a draw rate of 2.2 million barrels per day.

The drop wasn’t about consumption outpacing production on land. Floating inventories—tankers in transit or holding cargo at sea—fell by 63 million barrels, accounting for more than 90% of the overall decline. Renewed shipping risks through the Strait of Hormuz and the Bab el-Mandeb disrupted normal transit patterns, pushing arrivals higher in some regions while suppressing exports from others. The result was a sharp contraction in oil in motion.

By the end of July, global observed inventories had dropped below 7.9 billion barrels—a level not seen since April 2025. Cumulative stock draws from late February through July reached 410 million barrels, averaging 2.7 million barrels per day over that stretch. That’s a sustained pace of decline that puts real pressure on the market.

Remaining reserves are mostly crude, limiting relief for tightening product markets

There’s an important caveat to that 100-plus million barrels still uncommitted: most of it is crude oil, not refined products. That distinction matters more than it might seem.

Crude needs to be processed before it can address shortages of gasoline, diesel, or jet fuel. If market tightness is concentrated in products—and the IEA’s own framing suggests it increasingly is—releasing more crude doesn’t solve the problem directly. Supply gets added to one part of the chain while the bottleneck sits further downstream.

June’s floating inventory surge adds another wrinkle. When a temporary US-Iran ceasefire allowed Gulf shipments to resume, floating inventories jumped by 3.7 million barrels per day that month. July’s decline partly reversed that—meaning some of what looked like a build in June was temporary, and its unwinding in July amplified the apparent drop. The IEA noted that the timing of remaining releases will depend on market developments and broader oil supply security considerations in the months ahead, a deliberately open-ended framing that reflects genuine uncertainty.

Two forces pulling in opposite directions

July’s data captures two forces pulling in opposite directions. Better crude availability in Asia Pacific and a more measured pace of US SPR draws let the emergency release program step back from its earlier intensity. Global inventories still fell sharply, driven almost entirely by disrupted shipping through the Strait of Hormuz, erasing much of the cushion those earlier releases had built.

More than 100 million barrels remain available under the coordinated action. Their composition—mostly crude—limits how much direct relief they can offer to product markets that are growing tighter. The IEA has left the timing open, signaling it’s watching conditions closely before deciding how to deploy what’s left.
