Analyze the realistic throughput capacity of all known alternative supply routes and infrastructure if the Strait of Hormuz were…

Strait of Hormuz Baseline Flow

The Strait of Hormuz carried nearly 20 million barrels per day (mb/d) of crude oil and products in 2025, equivalent to 25% of global seaborne oil trade, with Saudi Arabia (5.43 mb/d crude), Iraq (3.32 mb/d), UAE (2.02 mb/d crude + 1.22 mb/d products), Kuwait, and others fully dependent on the route for exports to Asia (80% of flows).[1]
- Crude: 14.95 mb/d; products: 4.93 mb/d; total ~19.88 mb/d per IEA data.[1]
- A closure traps exports from Iraq, Kuwait, Qatar, Bahrain, and most of Iran/UAE/Saudi volumes, as no viable sea alternatives exist without the strait.
For competitors or new entrants in energy logistics, this highlights the irreplaceable nature of chokepoints—bypass infrastructure is country-specific and port-constrained, creating opportunities for non-Gulf suppliers (e.g., US, Brazil) but requiring years to scale terminals.

Saudi East-West Pipeline (Petroline) Realistic Capacity

Saudi Aramco's 1,200 km East-West Pipeline (Petroline) reroutes crude from Abqaiq processing (east) to Yanbu port (Red Sea), bypassing Hormuz entirely by leveraging parallel lines (upgraded post-2019 Abqaiq attacks); pipe capacity reaches 7 mb/d in emergencies, but Yanbu's two terminals limit sustainable exports to 4-4.5 mb/d due to loading bottlenecks (e.g., supertanker queuing, maintenance).[1][2]
- Design: 5 mb/d (two lines); expanded to 7 mb/d (March 2025); pre-crisis usage ~2 mb/d, spare 3-5 mb/d.[1]
- March 2026: Flows hit 5.9 mb/d (March 9), approaching pipe max but port-capped; Aramco CEO confirmed full activation imminent.[3]
This mechanism—pipe surge via NGL line conversion—offsets ~25% of Saudi's normal Hormuz exports (6 mb/d) but risks Red Sea attacks (Houthi precedent), implying non-obvious vulnerability to multi-front disruptions.
Entrants must prioritize port expansion over pipes; Yanbu's bottleneck shows terminal throughput dictates real capacity, favoring investments in VLCC-compatible buoys.

UAE Habshan-Fujairah (ADCOP/ADNOC) and Fujairah Terminal Capacity

UAE's 400 km Abu Dhabi Crude Oil Pipeline (ADCOP) pumps from Habshan fields to Fujairah (Gulf of Oman), avoiding Hormuz; 48-inch line handles 1.5 mb/d nameplate (1.8 mb/d max), with Fujairah terminal (70+ million barrel storage) exporting ~1.1-1.7 mb/d pre-crisis via onshore/offshore buoys, but realistic surge limited to 0.4-0.7 mb/d spare before queuing/logistics strain.[1][4]
- Pre-crisis: 1.1 mb/d exports; March 2026: 1.8 mb/d (full capacity, up from 1 mb/d).[3]
- Terminal: Handles UAE's Murban crude (50%+ exports); drone risks noted but resilient (42% storage growth 2018-2023).
Fujairah's buoy system enables quick VLCC loading but caps at pipeline flow—non-obvious implication: storage buffers short disruptions (days), not sustained ones, as blending/refining ties up space.
For market entry, emulate Fujairah's hub model: storage + bypass pipes create premium pricing power (~1.7% global demand), but security (drones) demands allied naval presence.

Iran IPSA/Goreh-Jask Pipeline Realistic Capacity

Iran's 1,000 km Goreh-Jask pipeline (often mislabeled IPSA; true IPSA is defunct Iraq-Saudi line) feeds Jask terminal (Gulf of Oman) with 1 mb/d nameplate, designed to diversify from Kharg Island (90% exports); however, it remains effectively non-operational in early 2026—single test cargo (late 2024), zero sustained throughput due to sanctions, technical issues, and self-blockade.[1][5]
- Capacity: 1 mb/d theoretical; effective: ~0.3 mb/d (2024 peak), halted post-Sept 2024; no 2026 flows amid war.
- Closure self-impacts Iran (1.69 mb/d crude Hormuz exports), netting zero offset.
Mechanism failure (sanctions block tankers) underscores political risk—bypasses exist but activate only in peacetime.
Competitors note: Iran's unreliability boosts rivals; non-Gulf producers gain as "sanction-proof" alternatives.

IEA and US SPR Inventories and Release Rates

IEA's 32 members hold 1.2 billion barrels public emergency stocks (+600 million mandated industry), enabling a record 400 million barrel release (March 11, 2026; US: 172 million over 120 days at ~1.4 mb/d); max collective drawdown unstated but past peaks ~1-1.2 mb/d (2022: 1 mb/d), with US SPR theoretical 4.4 mb/d but sustainable 1-1.2 mb/d (pipeline/infrastructure limits).[6]
- US SPR: 415-416 million barrels (March 2026); post-release: ~243 million (lowest in 44 years).[7]
- IEA plan: 72% crude/28% products; buys ~20 days at 20 mb/d loss but ramps slowly (13 days to market).
SPR mechanism—salt cavern drawdown + swaps—cushions prices short-term (e.g., 2022 offset 5% demand) but depletes buffers, exposing reliance on production ramps.
For entrants, SPR signals demand for flexible supply; post-release refills create buying opportunities at lows.

Net Supply Gap Calculation

Total Hormuz flow: 20 mb/d. Realistic offsets: 4.5 mb/d (Saudi ~4 mb/d port-limited + UAE 1.8 mb/d, minus pre-crisis ~3 mb/d usage = ~2.8 mb/d net new; Iran IPSA 0 mb/d; IEA aggregate 3.5-5.5 mb/d spare aligns). Gap: 20 - 4.5 = 15.5 mb/d (excludes SPR, as temporary).[1][3]
- Vs. global demand (~104 mb/d 2026 forecast): 15% shortfall.[8]
- With max SPR (~1.2 mb/d sustainable): Effective gap 14.3 mb/d (14%); lasts ~90 days at full draw.
Cause-effect: Port bottlenecks (not pipes) cap offsets at 20-25%; implies $100+/bbl prices until military reopening or production cuts (8 mb/d already curtailed March 2026).[8]
Entrants face high-barrier reality: Gap favors non-Mideast oil (US shale ramps 1+ mb/d possible), but sustained closure demands diversified imports/reserves; confidence high on data (IEA/EIA primary), though port flows need weekly tracking.

Recent Findings Supplement (March 2026)

Strait of Hormuz Baseline Flow and Closure Impact

The Strait of Hormuz carried ~20 million barrels per day (mb/d) of crude oil and products in 2025, equivalent to ~25% of global seaborne oil trade; its effective closure since late February 2026—due to Iran war mining, attacks, and insurance halts—has reduced flows to <10% of normal (~a trickle), forcing Gulf producers to curtail ~10 mb/d total liquids output (8 mb/d crude + 2 mb/d NGL/condensates) as storage fills, creating the largest supply disruption in oil market history per IEA's March 2026 report.[[1]](https://www.iea.org/reports/oil-market-report-march-2026)[[2]](https://iea.blob.core.windows.net/assets/a25ddf53-cd6c-4910-ac90-16bfd28399e7/-12MAR2026_OilMarketReport.pdf)
- Pre-closure: 15 mb/d crude + 5 mb/d products; Saudi ~5.6 mb/d, Iraq 3.3 mb/d, UAE 2.1 mb/d.[[3]](https://www.iea.org/about/oil-security-and-emergency-response/strait-of-hormuz)
- March 2026: Global supply plunges 8 mb/d to 98.8 mb/d; Gulf refining >3 mb/d shut-in.[2]
For competitors entering Gulf logistics, port bottlenecks (not just pipes) cap offsets at ~25% of Hormuz volume, requiring $10B+ terminal expansions for scalability.

Realistic Bypass Pipeline and Terminal Capacities

Saudi's Petroline (East-West) pipe hit 7 mb/d surge capacity in March 2026 via NGL line conversions, but Yanbu terminals limit sustainable exports to 4-4.5 mb/d (nominal) or ~4 mb/d tested, with 2 mb/d diverted to domestic refineries—mechanism: wartime shipping/logistics strain exceeds 2019 Abqaiq-attack tests, revealing original short-disruption design.[4]
- Aramco CEO: Full pipe capacity reached March 11; Yanbu averaged 2.2 mb/d early March (330% pre-war surge), peaking 5.9 mb/d March 9.[2]
- UAE Habshan-Fujairah (ADCOP): 1.5 mb/d nameplate (max 1.8 mb/d); March 1-10 average 1.8 mb/d pipe, but Fujairah loadings 2.4 mb/d early March, now disrupted by drone attacks (71% utilization pre-attacks, ~0.44 mb/d spare); 2025 exports >1.7 mb/d crude/fuels.[5][4]
New entrants face ~$2.8B/mb/d pipe cost + terminal hardening; IPSA dormant (1.65 mb/d potential, no 2026 reactivation).[6]
IEA total bypass: 3.5-5.5 mb/d (Saudi 3-5 mb/d spare, UAE ~0.7 mb/d extra).[3]

IEA and US SPR Inventories and Release Rates (Early 2026)

IEA members (32 countries) hold 1.25 billion barrels government emergency stocks + 600 million barrels obligated industry stocks (Jan 2026); unprecedented 400 million barrel release announced March 11 (33% of public stocks), via draws/other measures at national discretion—max historical rate ~1.3 mb/d (2022 Ukraine), potentially ~2 mb/d here, but stop-gap for ~20 days Hormuz loss.[1]
- US SPR: 416 million barrels (March 18, 2026; 155 sweet/261 sour; capacity 714 mb); max nominal drawdown 4.4 mb/d (13 days to market), but realistic ~1-1.4 mb/d (2022 precedent); plans 172 mb release over 120 days (~1.43 mb/d) as 43% of IEA total.[7]
Post-release SPR ~244 mb (42% drop). New policy: Swap mechanism sells high-price oil, repurchases 200 mb in 2027 at discounts. Entrants must navigate IEA coordination; US infrastructure limits beat paper rates.

Net Supply Gap Calculation

Hormuz ~20 mb/d minus realistic offsets 3.5-5.5 mb/d (IEA) = 14.5-16.5 mb/d gap; Gulf shut-ins already hit 10 mb/d, with March global supply -8 mb/d (refining -3 mb/d). Against IEA 2026 demand ~104.8 mb/d (growth slashed to 0.64 mb/d yoy amid crisis), gap = 14-16% global demand—SPR releases (~3 mb/d combined max) cover ~20% short-term, but storage exhaustion forces further cuts without Hormuz reopening.[2]
- Gap mechanics: No viable Iraq/Kuwait/Qatar bypass; Iran ~1 mb/d shadow exports persist.[3]
Implication: Non-Gulf producers (US LTO +0.38 mb/d potential) can't close >10 mb/d void long-term. Competitors: Gap favors non-Mideast producers, but logistics premiums erode margins.

Recent Policy and Infrastructure Updates (Post-Sep 2025)

Aramco activated Petroline full surge March 10-11 (CEO Nasser); ADNOC ramped ADCOP to 1.8 mb/d early March, but Fujairah/Yanbu drone hits expose vulnerabilities—no IPSA revival despite speculation. IEA March 12 report revises 2026 supply +1.1 mb/d (non-OPEC+ only), demand -0.21 mb/d on crisis; US SPR swap policy announced March 16. No new studies, but ENR/CNBC analyses confirm terminal moats.[4]
For market entry, 2026 activations prove pipes work but ports fail under attack—prioritize hardened Red Sea/Oman terminals over pipes. Confidence high on data (IEA/DOE primary); gap widens if closure >1 month.
