The demand cut did not loosen the balance

In its August Oil Market Report the IEA now expects world oil demand to fall 1.6 million barrels a day this year, 510,000 barrels a day more than it forecast in July. The agency points to the closed Strait of Hormuz and to fuel prices that have stayed high. It also reads the delivery data as a floor: May's year-on-year decline of 5.8 million barrels a day was the worst point, June came in at 4.8 million barrels a day, and the IEA expects demand to return to growth by November.[1]

The supply side moved further than that. Global supply rose 2.4 million barrels a day in July to 101.5 million barrels a day, yet stayed 6.3 million barrels a day below a year earlier, with 8.3 million barrels a day still shut in around the Gulf. Renewed hostilities took another 1.7 million barrels a day off the third-quarter supply path, and the third-quarter deficit widened to 1.8 million barrels a day from about 800,000 barrels a day in the July report. Weaker consumption is doing the rationing here, and it is still not covering the hole.[1]

Where does the buffer sit?

The gap has been covered out of storage. Globally observed crude oil inventories are now slightly below 7.9 billion barrels, a fall of 410 million barrels since the war began. Onshore crude stocks dropped only 6 million barrels in July, because the IEA's emergency stock releases slowed and Chinese inventories kept declining. The agency's own framing is blunt: reopening the strait has become more urgent precisely because the inventory buffers that used to be available are draining fast.[1]

Put next to the weekly American picture, that draw is a map problem as much as a volume problem. EIA data show commercial crude stocks outside the Strategic Petroleum Reserve rising 17.4 million barrels in the week to 7 August, to 424.4 million barrels, still about 2 per cent under the five-year average for the date. Barrels are piling up where refineries are already supplied and thinning where the shut-in production and the closed route are. A single global inventory number carries that difference inside it.[1], [2]

The next signal

Two days ago this column read the August Short-Term Energy Outlook as turning the Hormuz outage into a dated supply balance rather than a price event, arguing that the EIA gave the missing barrels a duration while Brent's daily swing gave them only a mood. The IEA report keeps that frame and pushes the date the wrong way: the third-quarter deficit it now expects is larger than the one it published a month ago. Timing and depth changed; the mechanism held.[3], [1]

Watch the onshore crude stack rather than the headline demand line. It fell just 6 million barrels in July while the observed global total kept sliding. If the strait stays closed through the third quarter and emergency releases do not accelerate, the IEA's next monthly report should show onshore crude drawing faster than 6 million barrels and the observed global total falling further below 7.9 billion barrels. A month of flat onshore stocks would say the shortage is still mostly offshore and in transit, and would weaken the case that the buffer is close to binding.[1]
