The Strait of Hormuz is a narrow maritime passage connecting the Persian Gulf (west) with the Gulf of Oman (east), which then opens into the Arabian Sea and wider Indian Ocean. It is the only sea passage from the oil-rich Persian Gulf to the open ocean, making it the world's most critical energy chokepoint.
The name "Hormuz" derives from the historic Kingdom of Hormuz (13th–17th century), a powerful trading state that controlled maritime trade in the region. Some historians trace it to the Middle Persian "Ohrmazd" (from Ahura Mazda, the Zoroastrian deity).
| Parameter | Detail |
|---|---|
| North Coast | Iran |
| South Coast | Musandam Peninsula (Oman exclave) + UAE strip |
| Width — narrowest | ~33 km (21 nautical miles) |
| Total length | ~167 km (90 nautical miles) |
| Shipping lanes | Two unidirectional lanes, each ~3 km wide, separated by a 3 km buffer |
| Depth | Sufficient for the world's largest VLCC crude oil tankers |
| Connects | Persian Gulf → Gulf of Oman → Arabian Sea → Indian Ocean |
| IMO Traffic Scheme | Traffic Separation Scheme managed by the International Maritime Organization |
Countries that rely exclusively on the Strait of Hormuz for maritime oil/gas exports (no pipeline alternative):
Only Saudi Arabia and the UAE have operational crude oil pipelines that bypass Hormuz. All other Persian Gulf states — Iran, Iraq, Kuwait, Qatar, Bahrain — have NO meaningful alternative maritime route.
| Water Body | Position | Key Feature |
|---|---|---|
| Persian Gulf | West of Hormuz | ~990 km long; 2/3 of world's proven oil reserves |
| Strait of Hormuz | The chokepoint | 33 km wide; only outlet from Persian Gulf |
| Gulf of Oman | East of Hormuz | ~560 km long; links Hormuz to Arabian Sea |
| Arabian Sea | Further east | Part of Indian Ocean; connects to Indian ports |
| Indian Ocean | Widest body | Connects Gulf to global markets |
UPSC frequently asks: "Which water body does the Strait of Hormuz connect?" Answer: Persian Gulf ↔ Gulf of Oman. Do NOT say "Arabian Sea directly" — the Gulf of Oman sits between Hormuz and the Arabian Sea. The correct sequence is: Persian Gulf → Strait of Hormuz → Gulf of Oman → Arabian Sea.
The Strait of Hormuz had never been fully, sustainably closed before 2026, despite decades of Iranian threats (unlike the Suez Canal, which was closed 1967–1975). The 2026 Iran War Crisis is the first prolonged closure in the strait's modern history.
| Metric | Value | Notes |
|---|---|---|
| Daily oil flow | ~20 million barrels/day | EIA 2024; roughly flat in Q1 2025 |
| Share of global petroleum consumption | ~20% | EIA; also stated as 1/5th |
| Share of global seaborne oil trade | ~25–27% | EIA/IEA — more than 1/4 |
| LNG trade share | ~20% of global LNG | 2023–25; primarily from Qatar |
| Asian market destination | 84% of crude oil; 83% of LNG | EIA 2024 |
| Top 4 Asian destinations | China, India, Japan, South Korea | 69% of all Hormuz crude flows |
| Fertilizer trade | Up to 30% of internationally traded fertilizers | Urea, ammonia from Gulf states |
| Tankers per day (pre-2026) | ~100–140 major vessels/day | Post-2026 crisis: collapsed by 90%+ |
| Saudi Arabia share of crude flows | 38% (5.5 mb/d) | Largest single exporter via Hormuz |
| War-risk insurance (pre-2026) | 0.125% of ship value/transit | Rose to 0.2–0.4% before 2026 conflict |
| Country | Risk Score | Key Factor |
|---|---|---|
| Japan | 6.4 (Highest) | 87% of total energy from imported fossil fuels |
| South Korea | 5.3 | 81% of total energy from imported fossil fuels |
| India | 4.9 | 35% energy from fossil fuel imports; huge volume |
| China | 4.4 | Produces own gas; diversified via pipelines too; 90% oil imports via Hormuz |
| USA | Very low | Net oil/gas exporter; only ~7% of crude from Persian Gulf |
China sources approximately 90% of its energy imports via the Strait of Hormuz — its highest single-route dependency in the world. Trump leveraged this in 2026 to pressure China to help reopen the strait.
The "20" cluster is UPSC gold: 20 mb/d of oil · ~20% of global petroleum consumption · ~20% of global LNG trade · 2-mile wide shipping lanes. The 84% Asian destination figure appears in recent MCQs. Don't confuse "seaborne oil trade share" (25%) with "global petroleum consumption" (20%).
| Island | Controller | Key Feature |
|---|---|---|
| Hormuz Island | Iran | Historically significant trading post; gave the strait its name; Portuguese fortress ruins visible |
| Qeshm Island | Iran | Largest island in the Persian Gulf; major economic free zone; strategic military significance |
| Hengam Island | Iran | Military significance; located near key shipping lanes |
| Greater Tunb | Iran (disputed) | Seized by Iran in 1971; claimed by UAE (Ras al-Khaimah). Controls navigation channel. |
| Lesser Tunb | Iran (disputed) | Seized by Iran in 1971; claimed by UAE (Ras al-Khaimah) |
| Abu Musa | Iran (disputed) | Joint administration disputed; claimed by Sharjah (UAE); oil revenues once shared |
| Larak Island | Iran | IRGC used this in 2026 as the northern route for "Tehran Toll Booth" traffic redirection |
The southern coast of the Strait is controlled by the Musandam Peninsula, which is an exclave of Oman — geographically separated from mainland Oman by UAE territory. A small southwestern strip of Musandam belongs to the UAE (Emirate of Ras al-Khaimah).
Musandam is governed as a separate governorate of Oman — the Musandam Governorate. Its main city is Khasab, which is also a major hub for cross-strait smuggling trade with Iran. The jagged coastline and fjords make it strategically important for naval observation.
| Element | Width | Detail |
|---|---|---|
| Inbound lane (to Persian Gulf) | ~3 km | Vessels run through Oman's territorial waters (southern side) |
| Buffer/separation zone | ~3 km | Keeps inbound/outbound traffic separated |
| Outbound lane (from Persian Gulf) | ~3 km | Also through Oman's waters — most ships use Omani side for navigation ease |
| Total navigable channel | ~9 km of the 33 km width used for shipping | Remaining width is shallow coastal areas |
The shipping lanes are each just 3 km wide — but students often say "2 miles" (which is approximately correct too, ~3.2 km). The strait's total width at narrowest is 33 km (21 nautical miles). The navigable shipping lane width ≠ total strait width. UPSC may test this distinction.
| Feature | Detail |
|---|---|
| Length of Persian Gulf | ~990 km long; 55–340 km wide |
| Average depth | ~50 metres (relatively shallow) |
| Proven oil reserves | ~2/3 of world's proven oil reserves |
| Natural gas reserves | ~1/3 of world's natural gas reserves |
| Bordering countries | Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, UAE |
| Gulf of Oman length | ~560 km; connects Persian Gulf (via Hormuz) to Arabian Sea |
| Arabian Sea | Part of Indian Ocean; separates Indian subcontinent from Arabian Peninsula |
All major islands in the Strait of Hormuz (Hormuz, Qeshm, Hengam) are controlled by Iran. Greater Tunb, Lesser Tunb, and Abu Musa are disputed between Iran and UAE — Iran controls them, UAE claims them. Qeshm is the largest island in the entire Persian Gulf — a frequently tested fact.
| Country | Primary Export | Bypass Alternative? | Notes |
|---|---|---|---|
| Saudi Arabia | Crude oil (largest volume) | ✅ Petroline (partial) | 38% of all Hormuz crude flows; 5.5 mb/d |
| Iraq | Crude oil | ✅ Kirkuk-Ceyhan (limited) | Southern Basra fields have NO alternative; heavily reliant |
| UAE | Crude oil + refined products | ✅ ADCOP (partial) | ADCOP bypasses for crude; refined products still need tanker routes |
| Kuwait | Crude oil | ❌ None | 100% dependent on Hormuz maritime route |
| Iran | Crude oil | ✅ Goreh-Jask pipeline (1 mb/d) | Jask terminal on Gulf of Oman bypasses Hormuz; limited capacity |
| Qatar | LNG (world's top exporter) | ❌ None for LNG | 100% of Qatari LNG must transit Hormuz; cannot move by pipeline |
| Bahrain | Petroleum products | ❌ None | Fully dependent on Hormuz route |
LNG (Liquefied Natural Gas) cannot be transported via pipeline once liquefied — it must travel by ship. Qatar's Ras Laffan terminal is one of the world's largest LNG export facilities. Qatar alone exports over 112 billion cubic metres of LNG annually, making it the world's top LNG exporter. ALL of this must transit the Strait of Hormuz.
A Hormuz closure would cause global LNG supply to drop by over 300 million cubic metres per day (mcm/d) — double the average gas that flowed through Nord Stream pipeline in 2021. Bangladesh and Pakistan get ~65% of LNG imports via Hormuz; India gets ~60% of LNG via Hormuz.
The Persian Gulf is a leading global hub for nitrogen fertilizer production. Countries like Iran, Qatar, Saudi Arabia, and Oman together account for roughly 30–35% of global urea exports and 20–30% of ammonia exports. Up to 30% of internationally traded fertilizers normally transit Hormuz — a disruption directly threatens global food security and planting seasons.
| Country | Role | Key Vulnerability |
|---|---|---|
| China | Largest single destination | ~90% of energy imports via Hormuz; 1st in absolute volume |
| India | 3rd largest oil consumer | ~40–50% of crude; ~60% of LNG; ~80–85% of LPG via Hormuz |
| Japan | Energy import dependent | 87% of total energy from imported fossil fuels; highest risk score |
| South Korea | Energy import dependent | 81% of total energy from imported fossil fuels; 2nd highest risk |
| Europe | Marginal but growing | ~10% of Hormuz oil destined for Europe (2025); LNG from Qatar ~7% |
UPSC often tests India's commodity-specific vulnerability: Crude oil ~40–50% via Hormuz (manageable with diversification); LNG ~60% (moderate risk); LPG 80–85% (most vulnerable — India holds no large strategic LPG reserves). The LPG angle is the most exam-tested.
Approximately 20 million barrels per day (mb/d) normally transit Hormuz. All existing bypass pipeline capacity combined — even at theoretical maximum — covers less than half of this volume. Moreover, every pipeline alternative has been shown to be vulnerable to Iranian drone/missile strikes, as demonstrated in 2026.
| Pipeline | Country | Route | Capacity | Notes |
|---|---|---|---|---|
| East-West Pipeline (Petroline) | Saudi Arabia | Abqaiq (Gulf coast) → Yanbu (Red Sea) | 7 mb/d (upgraded 2019) | 1,200 km; built during 1980s Tanker War; struck by Iranian drone in April 2026, back to full capacity in 3 days |
| ADCOP (Abu Dhabi Crude Oil Pipeline / Habshan-Fujairah) | UAE | Habshan → Fujairah (Gulf of Oman) | 1.5–1.8 mb/d | 380 km; operational 2012; exits directly into Indian Ocean bypassing Hormuz; Fujairah attacked by Iranian drones March 2026 |
| Goreh-Jask Pipeline | Iran | Goreh (Khuzestan) → Jask (Gulf of Oman) | ~1 mb/d | Iran's own bypass; allows export directly into Gulf of Oman; operational 2021 |
| Kirkuk-Ceyhan (Iraq-Turkey) | Iraq/Turkey | Kirkuk (Iraq) → Ceyhan (Mediterranean) | ~1.6 mb/d (operates at ~170–250 kb/d currently) | Via Kurdistan; restarted Sept 2023 after 2.5-year shutdown; only covers northern Iraqi fields, not Basra |
| Abqaiq-Yanbu NGL Pipeline | Saudi Arabia | Parallel to Petroline | 300 kb/d | Already fully utilised; no spare capacity |
Building pipeline infrastructure to fully replace Hormuz throughput would cost hundreds of billions of dollars and a decade of construction — and the finished pipelines would still be targetable by Iranian missiles and drones, as demonstrated in 2026.
UPSC may ask which countries have bypass pipelines. Answer: Only Saudi Arabia (Petroline, Red Sea) and UAE (ADCOP, Fujairah). Iran has the Goreh-Jask pipeline for its own exports. Iraq's Kirkuk-Ceyhan is for northern fields only. Kuwait, Bahrain, Qatar, and Iraq's southern (Basra) fields have no pipeline bypass.
| Legal Framework | Source | Key Rule | Iran's Position |
|---|---|---|---|
| Transit Passage | UNCLOS Articles 37–44 (1982) | All ships & aircraft have right of transit passage "which shall not be impeded" — NO suspension allowed, even in wartime | Iran signed but never ratified UNCLOS; claims it is not bound |
| Innocent Passage | 1958 Convention on Territorial Sea; Iran's 1993 Maritime Law | Iran claims only "innocent passage" applies — which can be suspended on security grounds; warships need prior authorization | Iran's preferred regime — gives it broader control powers |
| UN Charter Self-Defence | Article 51, UN Charter | Allows Iran to argue closure is self-defence against US-Israel attacks — but scale of third-party harm makes this contestable | Iran's argument during 2026 crisis |
| Article | Provision |
|---|---|
| Art. 37 | Applies to straits between one part of high seas/EEZ and another — Hormuz qualifies as an "international strait" |
| Art. 38 | All ships and aircraft enjoy right of transit passage — this right shall not be impeded |
| Art. 44 | States bordering straits shall not hamper transit passage and shall not suspend it — unqualified obligation |
| Art. 42 | Coastal states may regulate safety, pollution, customs — but tolls are explicitly absent from this list; Iran's "Tehran Toll Booth" (2026) is unlawful under Art. 42 |
Court: International Court of Justice (ICJ) · Year: 1949 · Parties: UK vs. Albania
Facts: Albania mined the Corfu Channel and UK warships were damaged passing through.
Holding: When a strait between two parts of high seas is used for international navigation, ships enjoy unrestricted passage during peacetime, so long as transit does not threaten a coastal state's security. Coastal states may prevent passage only in exceptional circumstances.
Significance for Hormuz: Laid the foundation for the UNCLOS transit passage framework. Widely cited to show that Iran's closure violates both treaty law and customary international law — even for states not party to UNCLOS.
| State | UNCLOS Status | Position on Hormuz |
|---|---|---|
| Iran | Signed 1982; never ratified | Claims not bound by transit passage; insists on "innocent passage" only; warships need prior permission |
| USA | Not a party | Argues transit passage is customary international law binding on all; conducts freedom of navigation operations |
| Oman | Ratified UNCLOS | But made declarations claiming sovereignty over territorial sea; requires warships' "prior permission" (UNCLOS bars such reservations) |
| India | Ratified UNCLOS (1995) | Supports freedom of navigation; conducts Operation Sankalp to escort vessels |
| Most EU states | Ratified UNCLOS | Support transit passage rights; declined US request to send warships (prefer diplomatic de-escalation) |
In April 2026, Iran began charging transit fees of up to $2 million per vessel to pass through Hormuz. This is illegal under UNCLOS Art. 42 (tolls not listed as permissible coastal state regulation), the 1958 Convention on Territorial Sea (pre-UNCLOS customary prohibition on tolling), and IMO rules. However, since Iran hasn't ratified UNCLOS, its legal vulnerability is contested — though the mainstream scholarly and institutional view holds the prohibition is binding via customary international law.
Key fact: Neither Iran nor the USA has ratified UNCLOS — yet both invoke it selectively. Iran claims it's not bound by transit passage; the US argues transit passage is customary law. The Corfu Channel case (1949) is the pre-UNCLOS precedent supporting freedom of navigation in international straits.
| Parameter | Detail |
|---|---|
| Launched | June 2019 (in response to tanker attacks and Stena Impero seizure) |
| Objective | Protect Indian-flagged merchant vessels in the Gulf of Oman & Persian Gulf |
| Force structure | Two task forces with Indian Navy warships deployed near Strait of Hormuz |
| Coverage area | Gulf of Oman, Persian Gulf, Strait of Hormuz corridor |
| Coordination agencies | Ministry of Defence, Ministry of External Affairs, Ministry of Shipping, Ministry of Petroleum & Natural Gas, DG Shipping |
| 2026 achievement | Between 14–24 March 2026, 5 Indian-flagged LPG carriers were evacuated from Hormuz in 3 separate operations, escorted by Indian Navy through Gulf of Oman |
| Diplomatic result | On 26 March 2026, Iran announced Indian ships are among those allowed to transit Hormuz (alongside Chinese, Russian, Iraqi, Pakistani vessels) |
| Location | State | Capacity |
|---|---|---|
| Visakhapatnam | Andhra Pradesh | Part of 5.33 MMT total |
| Mangaluru | Karnataka | Part of 5.33 MMT total (also hosts 3 MMT ADNOC commercial storage) |
| Padur | Karnataka | Part of 5.33 MMT total |
Total SPR capacity: 5.33 MMT (million metric tonnes) = ~21.4 million barrels · Provides ~9.5 days of net import cover. Commercial stocks by OMCs (IOCL, HPCL, BPCL) add ~60–65 days more. Total buffer: ~74–75 days. IEA recommends 90 days — India falls short. Phase-II expansion approved: additional 6.5 MMT → will cover 22 days of crude requirement once complete.
India signed an MoU with the UAE for strategic petroleum reserves storage at Fujairah (outside Hormuz, on Gulf of Oman). ADNOC stores commercial crude at India's Mangaluru facility, with 50% reserved for ISPRL use. This enables India to access Fujairah crude with zero Hormuz exposure.
| Feature | Detail |
|---|---|
| Location | Gulf of Oman, Iran — just outside the Strait of Hormuz entrance; avoids Hormuz chokepoint |
| India's investment | Over US$120 million invested; India operates Shahid Beheshti terminal |
| Primary strategic purpose | Trade corridor to Afghanistan and Central Asia bypassing Pakistan; INSTC (International North-South Transport Corridor) gateway |
| Hormuz angle | Located outside the strait on Gulf of Oman side — offers India connectivity to Iran and Central Asia without dependence on Hormuz passage |
| Link to INSTC | India is pushing to integrate Chabahar as the eastern extension of INSTC — connecting Indian Ocean to Central Asia and Russia via Iran |
| US sanctions | US granted India limited waivers for Chabahar investment — viewing it as a counter to China's Gwadar Port (Pakistan) |
The EIA identifies six major world oil transit chokepoints: Strait of Hormuz, Strait of Malacca, Suez Canal, Bab-el-Mandeb, Bosphorus, and Panama Canal.
| Chokepoint | Location | Oil Flow | Governing Law/Body | Bypass Option? |
|---|---|---|---|---|
| Strait of Hormuz | Iran / Oman-UAE | ~20 mb/d (20% global consumption) | UNCLOS (disputed); IMO Traffic Scheme | Partial only (Petroline, ADCOP) |
| Strait of Malacca | Malaysia / Indonesia / Singapore | ~23.7 mb/d (2023; more volume than Hormuz) | UNCLOS; IMO; trilateral patrols | Lombok/Makassar Straits (longer route) |
| Suez Canal | Egypt | ~4.2 mb/d + 10% global trade | Suez Canal Authority; 1888 Constantinople Convention | Cape of Good Hope (adds 10+ days) |
| Bab-el-Mandeb | Yemen-Djibouti-Eritrea | ~8–9 mb/d (3rd busiest) | International waters; no specific treaty | Cape of Good Hope |
| Bosphorus | Turkey | ~3.1 mb/d | 1936 Montreux Convention (Turkey has special rights) | Partial pipeline alternatives |
| Panama Canal | Panama | ~800 kb/d oil + 6% global trade | Panama Canal Authority |

By total oil volume, the Strait of Malacca (~23.7 mb/d) actually handles more oil than Hormuz (~20 mb/d). However, Hormuz is the "#1 chokepoint" because it has virtually no practical bypass — a full Hormuz closure strands the oil entirely, while Malacca has alternative routes (Lombok, Makassar). UPSC may test this nuance.
All points below are from verified sources with dates. This panel covers only Search Set A — live current affairs updates. This is the highest-salience Geography topic for UPSC Prelims 2026 given the ongoing crisis.
Following US airstrikes on three Iranian nuclear facilities (Natanz, Isfahan, Fordow) under "Operation Midnight Hammer" on 21–22 June 2025, Iran's parliament voted to authorize potential closure of the Strait of Hormuz. Oil prices spiked ~15% intraday; Brent crude approached $70/barrel. Global powers called for restraint; prices corrected. EU's top diplomat called any Iranian closure "extremely dangerous." The final decision was left to Iran's Supreme National Security Council — and no full closure occurred in June 2025.
On 28 February 2026, the US and Israel launched coordinated "Operation Epic Fury" airstrikes on Iranian military, nuclear sites, and leadership — resulting in the death of Supreme Leader Ali Khamenei. Iran's IRGC immediately began issuing VHF warnings forbidding ships from transiting Hormuz. By 2 March, IRGC officially declared the strait closed to "unfriendly nations." Sea mines were laid. At least 17 merchant ships were damaged; 7 abandoned; 12 seafarers killed or missing. Tanker traffic collapsed by 90%+, removing ~10 million barrels/day of supply. Global crude prices surged to Brent ~$100–$120/barrel. The 2026 Hormuz crisis became the largest energy disruption since the 1973 oil embargo.
India's response (March 2026): India's Ministry of Petroleum established a 24/7 control room. Refineries operated at 100%+ capacity. India diversified crude sourcing — 70% of imports now routed outside Hormuz (up from 55% baseline). Imports secured from 40+ countries. India secured ~30 million barrels of Russian crude under a US 30-day waiver. Domestic LPG production increased 25–36% by redirecting propane/butane streams. The Indian Crude Basket price reached US$113.57/barrel on 11 March 2026 — a sharp jump from the $62–70/barrel range seen earlier in FY2025–26.
Operation Sankalp escorted 5 Indian-flagged LPG carriers out of Hormuz in three missions (14–24 March 2026). On 26 March 2026, Iran's FM Araghchi announced Indian ships — alongside Chinese, Russian, Iraqi, and Pakistani vessels — were among nations allowed to transit the Strait. From 13 April 2026, the US imposed a naval blockade of Iranian ports, creating a "dual blockade" — Iran blocking commercial shipping, US blocking Iranian ports. China and Russia vetoed a UN Security Council resolution aimed at reopening the strait to commercial shipping (7 April 2026).
Iran began implementing the "Tehran Toll Booth" system in April 2026 — charging up to $2 million per vessel for passage, rerouting ships north of the traditional shipping corridor around Iran's Larak Islands. Secretary of State Marco Rubio called it "illegal, unacceptable, and dangerous." IMO Secretary General confirmed no international agreement authorizes tolls on international straits. Chatham House's international law analysis noted that Iran's closure is legally impermissible under customary international law even for a state not party to UNCLOS, since the prohibition on blocking international straits predates the convention.
India and UAE signed an MoU for strategic petroleum reserves cooperation (May 2026), enabling India to access Fujairah-origin crude bypassing Hormuz entirely. India held 21.4 million barrels in SPR as of March 2025 (EIA data). IEA member countries coordinated an emergency release of strategic oil stocks in March 2026. India is exploring leasing 5 million barrels of storage in Oman for SPR expansion. India's Phase-II SPR expansion (6.5 MMT additional) approved — will bring total coverage to 22 days of crude requirement once complete.
The 2026 Hormuz Crisis is the highest-salience current affairs event in Geography for UPSC Prelims 2026. Expect 1–3 questions on: (a) which countries have no bypass alternative, (b) India's crude diversification response, (c) UNCLOS legal framework, (d) Operation Sankalp, (e) SPR locations, (f) comparison with Malacca/Bab-el-Mandeb. Multiple UPSC coaching institutes (Vajiram, Drishti, Legacy IAS) have flagged this as the #1 Geography current affairs topic for 2026.
| Statement | T/F | Reason |
|---|---|---|
| The Strait of Hormuz connects the Persian Gulf to the Arabian Sea directly. | ❌ False | It connects Persian Gulf to the Gulf of Oman; Arabian Sea is further east. The sequence is: Persian Gulf → Hormuz → Gulf of Oman → Arabian Sea. |
| Qeshm is the largest island in the Persian Gulf and is controlled by Iran. | ✅ True | Qeshm is indeed the largest Persian Gulf island; controlled by Iran. |
| The narrowest point of the Strait of Hormuz is about 33 km (21 nautical miles) wide. | ✅ True | Correct — though some sources say 21 miles (not 21 nautical miles). 21 nm = 39 km; 33 km is the commonly cited figure. Both appear in sources. UPSC usually uses 33 km or 21 nautical miles. |
| Iran has ratified UNCLOS and is legally bound by its transit passage provisions. | ❌ False | Iran signed UNCLOS in 1982 but has never ratified it. Iran claims it is not bound by UNCLOS transit passage rules. |
| The Strait of Malacca carries more oil by volume than the Strait of Hormuz. | ✅ True | Malacca ~23.7 mb/d (2023) vs Hormuz ~20 mb/d. However, Hormuz is called the "world's #1 oil chokepoint" because it has virtually no practical bypass. |
| Saudi Arabia and the UAE are the only Gulf states with oil pipeline bypass routes around Hormuz. | ✅ True | Petroline (Saudi Arabia) and ADCOP (UAE) are the only operational crude bypass pipelines. Iran has Goreh-Jask for its own exports. Kuwait, Qatar, Bahrain, Iraq (south) have no bypass. |
| Operation Sankalp was launched by India in 2019 to protect Indian ships in the Red Sea. | ❌ False | Operation Sankalp was launched for the Gulf of Oman and Persian Gulf / Strait of Hormuz corridor — not the Red Sea. India launched separate anti-piracy operations in the Red Sea. |
| India's ISPRL operates strategic petroleum reserves at three locations: Visakhapatnam, Mangaluru, and Padur. | ✅ True | Correct — all three locations are in Karnataka and Andhra Pradesh. |
| All LNG exported through the Strait of Hormuz primarily originates from the UAE. | ❌ False | Primary LNG exporter via Hormuz is Qatar (world's top LNG exporter, ~112 bcm/year). UAE also exports LNG, but Qatar is the dominant source. |
| The Corfu Channel case (1949) established that innocent passage in international straits cannot be suspended during peacetime. | ✅ True | The ICJ ruling in the Corfu Channel case established exactly this — providing the basis for UNCLOS transit passage framework. |
The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman — NOT the Arabian Sea directly. The Gulf of Oman is an intermediate water body. Memorise the chain: Persian Gulf → Hormuz → Gulf of Oman → Arabian Sea → Indian Ocean.
The Strait of Malacca (~23.7 mb/d) handles more oil by volume than Hormuz (~20 mb/d). Hormuz is called the "#1 chokepoint" due to its lack of practical bypass — not total volume. UPSC may test this distinction.
Iran signed UNCLOS in 1982 but has never ratified it. The USA has also never ratified UNCLOS (despite being its biggest enforcer via freedom of navigation operations). Do not confuse signing with ratification.
Operation Sankalp was launched for the Gulf of Oman and Persian Gulf (specifically near Hormuz) in June 2019. India has separate anti-piracy missions (Operation Cactus, Operation Samudra Setu, etc.) in other areas. Do not confuse with Red Sea operations.
Qatar's LNG cannot be rerouted — there are zero pipeline bypass options for LNG. LNG must be shipped as liquid; it cannot travel by land pipeline. A full Hormuz closure strands ALL Qatari LNG. Global LNG supply would drop by 300+ mcm/d.
Bahrain is a country/archipelago in the Persian Gulf — but the largest island in the Persian Gulf is Qeshm (Iran), not Bahrain. This is a frequently tested fact in geography questions.
India's SPR covers only ~9.5 days of net import cover. Combined with commercial stocks, total buffer is ~74–75 days — below the IEA-recommended 90 days. Do not say "India meets IEA standards."
