Record US Crude Output Meets Volatile Gulf Flows as IEA Projects 1.8 Million Bpd Deficit
The IEA's August report shows OPEC+ recovering but Gulf volumes stay erratic, sustaining a 1.8 million bpd deficit despite US record crude output.
Saudi Arabia's crude production climbed to 8.24 million barrels per day in July from 7.34 million bpd in June, according to the IEA's August Oil Market Report, pushing total OPEC+ output from 33 million bpd in June to 34.53 million bpd. ICE Brent crude front-month held at $90.93 a barrel as of Tuesday (2026-08-18), sitting within the $81-$100 range a majority of participants in a Bloomberg Intelligence survey expected to prevail over the next 12 months.7,1
Those headline numbers look large against May's historic lows. But global oil production remained roughly 9.4 million bpd below pre-war levels as of June, the IEA reported, even after the sharp monthly recovery that followed partial restoration of Strait of Hormuz shipments. The agency projects a global oil deficit of 1.8 million bpd for the current quarter.5,6
Gulf flows have proved unstable. IEA data show loadings reached 20 million barrels per day in early July (2026-07), matching pre-conflict levels, before sliding to 12 million bpd later that month. A swing of eight million barrels per day within a single month, on a corridor that previously handled nearly 20% of global oil supply and roughly a quarter of worldwide seaborne trade, underlines how fragile the recovery remains. In 2025, about 18.2 million bpd of crude and refined products moved through the Strait, a volume that has been severely disrupted by the conflict.6,2
American production has been the largest non-Gulf offset. The United States has hit nearly 14 million barrels per day, a production record, and the EIA projects output will reach 14.1 million bpd in 2027, adding to a global supply picture already being reshaped by the conflict's redirection of trade flows. The UAE, operating outside OPEC, has been exporting record volumes as it draws down storage accumulated during the conflict.3,1
None of that has resolved the deficit. The IEA slashed its 2026 global oil supply forecast, projecting output will fall 4.3 million bpd across the year, and attributes the shortfall directly to sustained Hormuz disruption.6
US inventory data released on Thursday (2026-08-13) added a bearish counterpoint. Reuters reported that US crude stocks rose 17.4 million barrels in the latest weekly reading, the largest single-week build since January 2023, pushing inventories above 400 million barrels for the first time since April 2025. The build cut against the IEA's deficit framing and kept selling pressure on crude prices.7
OPEC's own June rebound came from a severe trough. Reuters' monthly survey put the 11 OPEC members at 19.43 million bpd in June, up 3.3 million bpd from May, when output fell to its lowest level in the survey since at least 2000. OPEC+ subsequently ratified another quota increase for August (2026-08).3,4
Trader positioning reflects the pull in both directions. The Bloomberg Intelligence survey from May (2026-05-21) found most respondents expected global disruptions to average 3 million to 7 million bpd, well below the actual peak. About a quarter expected more hedging and risk-management activity; only 15% anticipated opportunistic risk-taking.1
Middle East loadings ended late July (2026-07) at 12 million bpd, eight million barrels per day short of the early-month peak. The IEA's 1.8 million bpd deficit estimate for this quarter rests on partial Hormuz recovery holding. In July, it did not hold for the full month.6,7
