Processing bottleneck
Abqaiq showed crude stabilization capacity, not wellheads, is the binding constraint: half of Saudi output transited one ~7 mb/d plant in 2019. The pattern repeated in September 2026, when the East-West Pipeline was shut by damage to three pumping stations, not wells.
Evidence: EIA Today in Energy, Sep 2019 — 5.7 mb/d knocked out; ~7 mb/d capacity at Abqaiq ≈7% of global crude capacity; Reuters, Sep 17, 2026 — satellite analysis showing three East-West pumping stations damaged
Spare-capacity evaporation
Saudi Arabia is the supplier of last resort, and most OPEC spare capacity sits inside the Gulf — damage there removes the market's buffer, repricing the whole forward curve.
Evidence: IEA World Energy Outlook 2024 via Safety4Sea — a Hormuz closure would strand “the vast majority of OPEC spare capacity”, most of it inside the Gulf
Caveat: Pre-war spare-capacity levels are stale — the 2026 conflict has already stranded and consumed much of the buffer; treat IEA figures as an upper bound
Hormuz → LNG and Asian crude
Qatar was 18.7% of global LNG exports in 2025 and ~20% of global LNG trade transits Hormuz; ~84% of Hormuz crude went to Asian buyers. The East-West Pipeline — the main bypass — is itself hit, so rerouting options are thinner than in 2019.
Evidence: IGU World LNG Report 2026 — Qatar 81.5 Mt, 18.7% of global exports; EIA chokepoints — ~20% of LNG trade via Hormuz; EIA data via SpeedCommerce (secondary) — ~84% of Hormuz crude to Asia
Caveat: Hormuz is already largely shut in 2026 — this models NEW physical damage, not first-time closure; the 84% Asian-crude share is secondary-sourced
Inventory drawdown bridge
Abqaiq's price spike decayed in days because Saudi inventories bridged exports during the ~11-day repair — duration, not size, sets the tail. In 2026 the bridge is already partly spent after months of conflict.
Evidence: Saudi officials via Reuters, Sep 2019 — customer supplies maintained from inventories; Reuters, Sep 30, 2019 — full capacity restored Sep 25; PVM Oil Associates via Reuters, Aug 2026 — “supply risk will persist and oil inventories will continue to deplete”
Product pass-through
Crude does not stay in the Gulf: EIA's longstanding guideline is that each $1/bbl of sustained crude change ≈ 2.4¢/gallon of US gasoline — a measure of pump-level exposure, not a price prediction.
Evidence: EIA Today in Energy — $1/bbl ≈ 2.4¢/gallon of gasoline (1/42 of $1, one barrel = 42 gallons)
