Inventory buffers are nearing depletion, and upside oil price risks are building
Bernstein believes that continued Middle East supply disruptions and the gradual exhaustion of SPR and Chinese inventory buffers could support a 2026 average Brent price of about US$90/bbl, with a risk of breaking above US$100/bbl within the year if OECD commercial inventories continue to decline.
- Seaborne crude oil flows from the Middle East remain significantly disrupted, with Strait of Hormuz volumes falling from about 20MMbbls/d before the conflict to about 3.4MMbbls/d.
- Of the 400MMbbl emergency SPR release, about 290MMbbl, or 73%, has already been consumed and could be exhausted before the end of September at the current pace.
- China has reduced seaborne imports from about 14MMbbls/d to about 5MMbbls/d and has buffered the global balance through inventory drawdowns, but at the current pace reserves could fall to 60 days of coverage by year-end.
- The report expects OECD commercial inventories to decline by at least another 100MMbbl in 2H26; historically, every 100MMbbl decline roughly corresponds to an oil price increase of about US$10/bbl.
Report interpretation
Overview
This report discusses the impact of the prolonged Middle East conflict on global crude oil supply and demand, inventory buffers, and Asia Pacific oil and gas equities. The report argues that the market has previously absorbed Middle East export disruptions through SPR releases, China's reduced imports and inventory drawdowns, demand destruction, and some non-OPEC supply growth, but these buffers are not unlimited. As SPR and Chinese inventories approach constraints, more of the balancing pressure will shift to OECD commercial inventories and oil prices.
Core views
The core view is that oil price risks are skewed to the upside. Bernstein forecasts average Brent of about US$90/bbl in 2026, about US$78/bbl in 2027, and a long-term assumption of about US$75/bbl, all reflecting a tighter physical market, geopolitical risk premium, and higher marginal supply costs. If Middle East logistics fail to recover and OECD commercial inventories decline by another roughly 100MMbbl, the probability of Brent exceeding US$100/bbl before year-end rises. Within Asia Pacific oil and gas equities, the report continues to favor Santos, PetroChina, and CNOOC.
Analysis framework
The report uses a global crude oil supply-demand balance framework, decomposing Middle East seaborne export losses into offsetting items such as SPR releases, changes in OECD commercial inventories, changes in Chinese inventories, oil-on-water inventories, non-OECD inventories, and demand destruction, while tracking seaborne flows, inventories, and price assumptions using data from Kpler, IEA, EIA, Bloomberg, NBS, and PAJ.
Methodology notes
Attributes supply losses against inventory changes, demand destruction, and substitute supply.
The report estimates that Middle East seaborne export disruptions caused a net supply loss of about 11.3MMbbls/d. Observable SPR and Chinese inventories offset about 4MMbbls/d, with the remainder mainly absorbed by demand destruction and incompletely observable inventory adjustments.
Every 100MMbbl decline in OECD commercial inventories roughly corresponds to about a US$10/bbl increase in oil prices.
The report uses this empirical relationship to assess the asymmetric upside risk to oil prices once inventory buffers are exhausted.
Compares oil price assumptions, production, P/CF, free cash flow yield, payout ratio, and dividend yield.
The report presents long-term financial and valuation comparisons for companies including PetroChina, Sinopec, CNOOC, Woodside, Santos, Inpex, and PTTEP to support sector and stock preferences.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Brent crude oilCore pricing variable
- Strengths
- Falling inventories and Middle East supply disruptions provide price support, with a 2026 average price forecast of about US$90/bbl.
- Weaknesses
- Upside may be limited if Middle East flows recover, demand weakens further, or policymakers release more reserves.
- Comparison
- The report forecast is above the roughly US$83/bbl consensus and the roughly US$86/bbl forward curve.
- Risks
- De-escalation of the conflict could reduce the risk premium; weak global demand could reduce inventory drawdowns.

Key data

- OECD commercial inventoriesabout 2.7bn barrelsDown about 116MMbbls since the conflict began.
- China crude oil importsdown from about 14MMbbls/d to about 5MMbbls/dChina has become an important buffer to the global balance by reducing imports and drawing down inventories.
- Estimated total China oil inventoriesabout 1,391MMbblsThe report believes that at the current depletion pace, coverage could approach 60 days by year-end.
- Cumulative decline in Asian importsabout 884MMbblsReflects constrained crude availability and demand adjustment.
- Oil-on-water inventoriesabout 1.9bn barrelsHad largely recovered to pre-conflict levels by July, but could be drawn down again if disruptions persist.
Impact & implications
For investors, the depletion of inventory buffers means oil prices may become more sensitive to supply disruptions, benefiting upstream oil and gas companies and those with greater cash flow sensitivity to Brent. The report maintains a constructive stance on the Asia Pacific oil and gas sector, with particular preference for Santos, PetroChina, and CNOOC; at the same time, economies or companies with higher refining exposure and import dependence may face cost pressure.
Risks
- If the Middle East conflict eases quickly and Strait of Hormuz and regional seaborne flows recover, the oil price risk premium could decline.
- Policymakers may add further SPR releases or adopt other intervention measures to temporarily ease pressure on commercial inventories.
- High oil prices could trigger stronger demand destruction, causing price gains to undershoot what inventory models imply.
- There is estimation uncertainty around the true pace of China's inventory drawdowns and import adjustments.
- Non-OPEC supply growth or unobservable inventory changes could offset part of the supply shortfall.
What to watch
- Whether seaborne flows through the Strait of Hormuz, the Red Sea, and Fujairah continue to recover or deteriorate again.
- The pace of OECD and U.S. SPR releases, and whether new emergency release authorizations are added.
- Whether weekly U.S. commercial crude and product inventories continue to remain below the five-year range.
- Changes in China's crude imports, refinery run rates, and inventory coverage days.
- Whether OECD commercial inventories decline by another roughly 100MMbbls in 2H26.
- Whether Brent stabilizes around US$90/bbl and breaks toward US$100/bbl.
