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.

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.
