PRELIMS Geography Β· Maritime Chokepoints & India's Trade/Energy Security
The Strait of Hormuz β€” just 33–39 km wide between Iran and Oman's Musandam Peninsula β€” is the world's single most critical energy chokepoint, carrying ~20 million barrels per day (~25% of global seaborne oil) as of 2025. The Bab-el-Mandeb ("Gate of Tears"), connecting the Red Sea to the Gulf of Aden between Yemen and Djibouti/Eritrea, handles ~4.2 million barrels/day and ~14% of global maritime trade. India is among the world's most exposed nations β€” with 62% of crude oil imports historically transiting Hormuz, 90% of LPG imports passing through it, and India being the world's largest urea importer, with fertiliser also routing through these straits. As of June 2026, both straits face unprecedented disruption from the 2026 Iran–US–Israel conflict, triggering Operation Urja Suraksha and forcing India to reroute ~70% of crude away from Hormuz.

Core Concept & Definition β€” Maritime Chokepoints & UNCLOS Framework

What Is a Maritime Chokepoint?

A maritime chokepoint is a narrow, strategically vital sea passage through which a disproportionately large volume of global trade and energy must pass. Any disruption β€” geopolitical, military, or environmental β€” immediately ripples into global commodity prices, insurance costs, and supply chains. The word "chokepoint" derives from military strategy: a narrow passage where a small force can "choke off" a much larger flow.

Key Terminology β€” Maritime Chokepoints
TermMeaningRelevance
ChokepointNarrow sea passage with outsized global trade significanceBoth Hormuz & Bab-el-Mandeb qualify
StraitNatural narrow waterway connecting two larger bodies of waterHormuz: Persian Gulf ↔ Gulf of Oman; Bab-el-Mandeb: Red Sea ↔ Gulf of Aden
Innocent PassageRight of foreign ships to pass through territorial sea (≀12 nm) without stoppingUNCLOS Article 19 β€” can be suspended by coastal state in certain conditions
Transit PassageNon-suspendable right of passage through straits used for international navigationUNCLOS Articles 37–38 β€” applies to Hormuz & Bab-el-Mandeb; cannot be legally blocked
TSS (Traffic Separation Scheme)Designated inbound/outbound shipping lanes to prevent collisions in narrow straitsBoth Hormuz and Bab-el-Mandeb use TSS lanes managed under IMO rules
Freedom of Navigation (FON)Right of all nations' ships to traverse international waters and straitsUnderpins US/India naval operations when challenged
UNCLOS 1982UN Convention on Law of the Sea β€” foundational maritime law treatyIndia ratified; Iran is NOT a signatory β€” critical UPSC distinction
πŸ“Œ Micro-Fact

UNCLOS Part III (Articles 34–45) governs straits used for international navigation. Article 37 defines which straits it applies to; Article 38 grants right of transit passage. Iran, which is NOT a party to UNCLOS, claims it can restrict passage β€” a position rejected by the international community.

πŸ’‘ Exam Tip

UPSC frequently tests the distinction between Innocent Passage (suspendable, applies to territorial sea broadly) and Transit Passage (non-suspendable, applies specifically to international straits). Hormuz qualifies for Transit Passage β€” Iran cannot legally close it under UNCLOS.

Bottom Line: Both Hormuz and Bab-el-Mandeb are international straits subject to non-suspendable transit passage rights under UNCLOS Articles 37–38 β€” but Iran (not a UNCLOS party) disputes this, making the legal and strategic tension highly exam-relevant.

Geographical Profile β€” Physical Dimensions, Bordering Nations & Key Islands
πŸ›’ Strait of Hormuz
  • Connects: Persian Gulf ↔ Gulf of Oman
  • Width (min): ~33–39 km (21–24 miles)
  • Depth: 60–100 m; shipping lanes >25 m
  • Northern coast: Iran (+ contested islands)
  • Southern coast: Oman (Musandam Peninsula exclave) & UAE
  • TSS: Two 2-mile inbound/outbound lanes + 2-mile median β€” in Omani territorial waters
  • Key contested islands: Abu Musa, Greater & Lesser Tunb (Iran–UAE dispute)
  • Coordinates: ~26.5Β°N, 56.5Β°E
  • Adjacent seas: Arabian Sea (via Gulf of Oman)
βš“ Bab-el-Mandeb
  • Connects: Red Sea ↔ Gulf of Aden (β†’ Indian Ocean)
  • Width (overall): ~32 km (20 miles) at narrowest
  • Max length: ~50 km (31 miles)
  • Average depth: ~186 m (609 ft)
  • NE coast: Yemen (Arabian Peninsula)
  • SW coast: Djibouti & Eritrea (Horn of Africa)
  • Key island: Perim (Mayyun) β€” Yemeni volcanic island, divides strait into 2 channels
  • Western channel: 26 km wide, 198 m deep β€” used by all large vessels
  • Eastern channel: Only ~3 km wide β€” local traffic only
  • Other islands: Seven Brothers (near Djibouti)
  • Coordinates: ~12.6Β°N, 43.3Β°E
Bordering Countries β€” Quick Reference

DjiboutiSW (Africa)Host to French, US, Chinese, Japanese & Indian military bases β€” most militarised small nation on Earth
EritreaSW (Africa)Dahlak Archipelago lies to north; Assab port on Red Sea coast
πŸ“Œ Micro-Fact β€” The Musandam Puzzle

Oman's Musandam Peninsula is a dramatic fjord-carved exclave at the tip of the Arabian Peninsula β€” it is physically separated from mainland Oman by UAE territory. Inside the UAE, there is also a pocket of Omani territory called Madha (~75 kmΒ²) β€” an enclave within an exclave. The TSS shipping lanes of Hormuz run through Omani territorial waters, not Iranian.

⚠ Common Trap

Many students write that Saudi Arabia borders the Strait of Hormuz β€” this is WRONG. Saudi Arabia has no coastline on the Strait of Hormuz. The strait's southern coast is Oman (Musandam) and UAE only. Saudi Arabia's main ports are on the Red Sea (Jeddah, Yanbu) and the Persian Gulf (Dammam, Jubail) β€” but it does NOT touch the strait itself.

Exam-Ready Summary: Hormuz = Iran (N) + Oman/UAE (S) | Bab-el-Mandeb = Yemen (NE) + Djibouti + Eritrea (SW) | Perim Island divides Bab-el-Mandeb into west (deep, commercial) and east (shallow, local) channels | TSS of Hormuz is in Omani waters.

Historical Evolution
3
Historical Evolution β€” Ancient Trade Routes to the 2026 Crisis
Ancient Times β€” c. 325 BCE
Earliest civilisations of Mesopotamia and the Indus Valley used Hormuz for trade in spices, pearls, and frankincense. Greek admiral Nearchus, under Alexander the Great, made the first recorded survey voyage through the strait (325 BCE) proving a navigable corridor between India and the Iranian heartland.
13th–17th Century CE
The Kingdom of Hormuz (Ormus) flourished as a powerful trading state; Hormuz Island was the region's premier commercial hub, controlling sea trade between India, Persia, and the Arab world. The name "Hormuz" derives from this kingdom.
1507 β€” Portuguese Control
Portuguese admiral Afonso de Albuquerque captured Hormuz Island, recognising it as the key to controlling all trade between India and the Mediterranean. Portugal maintained dominance for over a century. The British later acquired Perim Island (Bab-el-Mandeb) in 1799 during the Napoleonic Wars as a coal-refuelling station for steam ships.
1856 β€” British Occupation of Perim
Britain fully occupied Perim Island in Bab-el-Mandeb, fearing French influence through the Suez Canal then under construction. Perim was used as a refuelling station for the Royal Navy's route to India. Handed over to newly independent South Yemen in 1967.
1979 β€” Iranian Revolution
Iran's Islamic Revolution transformed Hormuz from a commercial passage into a geopolitical flashpoint. Iran began occupying Abu Musa and Tunb islands (claimed by UAE), establishing a permanent military presence that strengthens its de facto control over the strait.
1984–1988 β€” Iran–Iraq Tanker War
Iran and Iraq attacked each other's oil tankers in the Gulf and Hormuz. 411 vessels attacked, 239 petroleum tankers. The US launched Operation Earnest Will (1987) to escort Kuwaiti tankers through Hormuz. Iran mined the strait; the US military destroyed Iranian oil platforms in retaliation. First major modern proof that a single actor could massively disrupt global oil flows through Hormuz.
2019 β€” Indian Navy's Operation Sankalp
Following attacks on oil tankers near Hormuz (MV Front Altair, MV Kokuka Courageous), India launched Operation Sankalp on 19 June 2019 β€” deploying frigates and destroyers to escort Indian-flagged vessels through Hormuz and the Gulf of Oman.
November 2023 – October 2025 β€” Red Sea Crisis (Houthi Attacks)
Iran-backed Houthis in Yemen began attacking commercial ships in the Red Sea and near Bab-el-Mandeb (November 2023) in solidarity with Gaza. Container traffic through Suez Canal fell from 26,000 ships (2023) to ~13,000 (2024). Major shipping companies (Maersk, MSC, CMA CGM) rerouted around Cape of Good Hope. Suez Canal Authority lost ~$7 billion in revenue. Crisis eased following October 2025 Hamas–Israel ceasefire.
28 February 2026 β€” 2026 Hormuz Crisis (ONGOING)
US and Israeli airstrikes against Iran triggered the 2026 Iran–US–Israel war. Iran announced closure of Hormuz to "unfriendly nations"; IRGC boarded and attacked merchant ships; sea mines laid. By March 2026 only vessels from 5 permitted nations (China, Russia, India, Iraq, Pakistan) could transit. Brent crude surged from ~$72 (Feb 27) to $110 by end-April 2026. Over 18 vessels attacked. Houthis simultaneously threatened Bab-el-Mandeb. A Persian Gulf Strait Authority was formed under US pressure.
βœ… Key Historical Fact

The name "Bab-el-Mandeb" is Arabic for "Gate of Tears" β€” referring to the historically treacherous navigation conditions. An Arabic legend says it was named after an earthquake that separated Africa from Arabia, drowning many. In ancient texts it was called "Bab Iskender" (Alexander's Gate) for the eastern channel.

πŸ“Š Critical Data β€” IEA, 2025

In 2025, nearly 15 mb/d of crude oil (34% of global crude trade) passed through Hormuz. China and India combined received 44% of those exports. Asia as a whole imported 14.74 million barrels per day of Middle Eastern crude in 2025 β€” nearly 60% of the region's total purchases.

β˜… Important β€” Food Security Angle

A dual closure of Hormuz + Bab-el-Mandeb creates a near-complete sea blockade for grain imports to the Gulf and parts of Asia. One-third of global seaborne fertiliser trade transits Hormuz; 46% of global urea trade originates from the region. Urea prices rose 86% from January 2026 following the Hormuz closure β€” devastating for India (world's largest urea importer).

Data Anchor: Hormuz = 20 mb/d oil + 34% global crude + 20% LNG | Bab-el-Mandeb = 4.2 mb/d oil + 14% maritime trade + 20% global rice | Dual closure = $10 billion/day global trade risk

Bypass Routes & Alternatives β€” What Can and Cannot Circumvent These Straits
Bypass Routes for Strait of Hormuz β€” Key Facts
Route / InfrastructureCountryCapacityKey Details
Petroline (East-West Crude Pipeline / Abqaiq-Yanbu)Saudi ArabiaUp to 7 mb/d (upgraded 2025); ~2 mb/d in active use (early 2026)Connects Abqaiq (Eastern Province) to Yanbu (Red Sea). Oil then exits via Bab-el-Mandeb, NOT Hormuz. Spare capacity 3–5 mb/d.
ADCO/Habshan–Fujairah Pipeline (UAE)UAE~1.5 mb/dConnects Abu Dhabi oilfields to Fujairah port on Gulf of Oman β€” completely bypasses Hormuz
Goreh–Jask Pipeline (Iran)Iran~1 mb/dOpened 2021; allows Iran to export from Jask terminal on Gulf of Oman, bypassing Hormuz. Limited use so far.

Bypass Routes for Bab-el-Mandeb
Route / InfrastructureOperatorCapacityDetails
SUMED Pipeline (Suez-Mediterranean)Egypt~2.3 mb/dConnects Ain Sukhna (Red Sea) to Sidi Kerir (Mediterranean) β€” bypasses Suez Canal but does NOT bypass Bab-el-Mandeb (oil still enters Red Sea through Bab)
Suez Canal itselfEgypt~4.9 mb/d (oil) + containersPaired with Bab-el-Mandeb β€” if Bab is blocked, Suez also effectively blocked for vessels coming from Indian Ocean
Cape of Good Hope RouteAll shippingUnlimited (but costly)Adds 10–14 days and US$1.2–1.8 million in extra fuel costs per round trip. In H1 2025, Cape traffic was 9.1 mb/d (up from 6.0 mb/d in 2023). War-risk insurance premiums rose 1,000%+ from pre-crisis levels (2026).
⚠ Critical Trap β€” The Hormuz Bypass Illusion

Even when Saudi Arabia uses the Petroline to bypass Hormuz, the oil still flows to Yanbu on the Red Sea β€” and then MUST exit through Bab-el-Mandeb to reach European and Asian markets. So: Petroline bypasses Hormuz but NOT Bab-el-Mandeb. A dual closure of both leaves no viable bypass for most Persian Gulf energy exports. The UAE–Fujairah pipeline is the ONLY route that bypasses Hormuz AND doesn't require Bab-el-Mandeb (Fujairah exports directly to Gulf of Oman).

βœ… Can Bypass Hormuz
  • Saudi Arabia via Petroline β†’ Yanbu
  • UAE via Habshan–Fujairah pipeline
  • Iran via Goreh–Jask (limited)
  • Iraq via Kirkuk–Ceyhan (disrupted)
❌ Cannot Bypass β€” Must Use Cape of Good Hope
  • Iraq, Kuwait, Qatar, Bahrain
  • Most Qatari LNG to Europe/Asia
  • All container ships through Gulf ports (Jebel Ali)
  • Saudi Petroline oil still exits via Bab-el-Mandeb
Key Rule: Hormuz has limited pipeline bypass options (Petroline, UAE Habshan). Bab-el-Mandeb has no meaningful bypass β€” Suez/SUMED are downstream of Bab, and the Cape of Good Hope is the only alternative, adding 10–14 days and ~$1.5M/round trip.

πŸ“Œ Micro-Fact β€” SPR vs IEA Standard

The IEA standard is 90 days of crude oil storage. India's SPR covers only 9.5 days at full capacity (Phase 1). Combined with commercial stocks, India has ~74 days total β€” still below the IEA norm. As of March 2026, SPRs were only 64% filled (~5 days effective coverage), raising acute concern during the Hormuz crisis.

β˜… Macro-Risk Chain β€” Every $10 Rise in Crude

Every $10/barrel rise in crude oil increases India's import bill by ~$12–15 billion/year, widens the Current Account Deficit, puts downward pressure on the Rupee, and feeds retail inflation through transport, fertiliser, and input cost channels. Brent crude rose from ~$72 (Feb 2026) to ~$110 (April 2026) β€” the Hormuz crisis effectively increased India's annual oil import bill by tens of billions of dollars.

India's Vulnerability Snapshot: 62% crude + 90% LPG + world's #1 urea importer all transit Hormuz. SPR = only 9.5 days (Phase 1, 5.33 MMT). Current 64% fill = ~5 days actual buffer. IEA norm = 90 days. Gap = structural energy insecurity.

India's Alternative Connectivity Corridors

πŸ›€ IMEC β€” India-Middle East-Europe Economic Corridor

Announced at G20 New Delhi 2023; endorsed by US President Trump in February 2025. Connects Indian ports β†’ Gulf states (UAE, Saudi Arabia, Jordan) β†’ Israel β†’ Europe. Explicit energy infrastructure pillar linking Indian ports to European markets via overland pipelines and rail, bypassing maritime chokepoints. Backed by India, Saudi Arabia, UAE, Jordan, Israel, EU.

πŸ›€ INSTC β€” International North-South Transport Corridor

Connects India β†’ Iran β†’ Central Asia β†’ Russia. A multimodal (ship + rail + road) corridor. India invested in Chabahar Port (Iran, on Gulf of Oman) as a key node β€” this port is outside the Hormuz strait and gives India strategic access to Afghanistan and Central Asia without going through Pakistan.

πŸ›’ Supply Diversification (Post-2026)

India rerouted roughly 70% of crude imports away from Hormuz (up from 55%) by March 2026. Sources used: Russian crude (discounted, via US waivers), Latin America, West Africa, Saudi Yanbu port (via Red Sea/Cape of Good Hope), UAE Fujairah. India's first VLCC terminal at Mundra Port (launched January 2026) enhances capacity to receive non-Hormuz supplies.

πŸ“Œ Micro-Fact β€” India Permitted Through Hormuz (2026)

On 26 March 2026, Iranian FM Abbas Araghchi announced that vessels from 5 nations β€” China, Russia, India, Iraq, and Pakistan β€” would be permitted to transit the Strait of Hormuz. India's diplomatic relations with Iran (and non-alignment in the US-Israel-Iran conflict) directly secured this exemption β€” a unique geopolitical benefit of India's "strategic autonomy" doctrine.

πŸ’‘ Exam Tip

UPSC frequently asks about Operation Sankalp β€” its launch date (19 June 2019), the Sanskrit meaning ("Commitment"), the triggering incident (tanker attacks in Gulf of Oman), and its scope (Hormuz + Gulf of Aden). Also: Chabahar Port and INSTC are standard Prelims/Mains linkages for this topic.

India's Response Framework: Military (Op Sankalp 2019; Op Urja Suraksha 2026) + Diplomatic (Hormuz exemption via Iran ties) + Structural (IMEC, INSTC, Chabahar, SPR Phase 2, Mundra VLCC terminal, source diversification).

βœ… Key Distinction β€” Hormuz vs Malacca

Strait of Malacca handles the highest volume of maritime trade by value (~20%) and vessel count. However, Strait of Hormuz is uniquely critical for energy security β€” it is the ONLY maritime exit from the Persian Gulf, making it irreplaceable. Malacca has no such exclusive geographical position. Hormuz = no alternative. Malacca = Singapore Strait and Lombok/Sunda Straits as alternatives (albeit longer).

Djibouti (population ~1.1 million; area 23,200 kmΒ²) bordering Bab-el-Mandeb hosts military bases of: USA (Camp Lemonnier β€” only permanent US base in Africa), France (oldest foreign French base), China (China's first overseas military base, est. 2017), Japan, and Italy. This makes it the most strategically militarised small nation relative to size β€” its entire economy is structured around strategic hosting.

Ranking Memory Aid: By oil volume: Malacca (23.2) > Hormuz (20.9) > Danish Straits (4.9) β‰ˆ Suez (4.9) > Bab-el-Mandeb (4.2) | By replaceability: Hormuz is irreplaceable (only Gulf exit). By India's energy dependence: Hormuz > Bab-el-Mandeb > Malacca.

Current Affairs β€” Strait of Hormuz & Bab-el-Mandeb (Search Set A Β· Live Updates)
πŸ“Š Current Affairs β€” Wikipedia / Multiple Sources Β· February–June 2026

2026 Hormuz Crisis (28 Feb 2026 β€” Ongoing): Following US–Israeli airstrikes against Iran that began 28 February 2026, Iran announced closure of the Strait of Hormuz to "unfriendly nations." The IRGC issued VHF warnings, boarded and attacked merchant ships, and laid sea mines. Shipping traffic dropped to ~5% of pre-conflict levels. At least 18 vessels were attacked, 1 tugboat sunk, 2 merchant ships captured, 12 seafarers killed/missing. Brent crude rose from ~$72 (Feb 27) to ~$110 by end-April 2026. A Persian Gulf Strait Authority was formed under US pressure. US–Iran ceasefire is fragile as of June 2026.

πŸ“Š Current Affairs β€” ORF Middle East Β· April 23, 2026

Dual Chokepoint Risk Quantified: A combined Hormuz + Bab-el-Mandeb disruption places an estimated $10 billion per day of global trade at risk. Maersk, CMA CGM, and Hapag-Lloyd began rerouting around the Cape of Good Hope (March 2026), with war-risk insurance premiums soaring more than 1,000%. Cape of Good Hope routing adds US$1.2–1.8 million per round trip in fuel costs. Urea prices rose 86% from January 2026 β€” India (world's largest urea importer) and Brazil are most severely affected.

πŸ“Š Current Affairs β€” Atlantic Council / Geopolitical Monitor Β· March–April 2026

India's Diplomatic Exemption (26 March 2026): Iranian FM Abbas Araghchi announced that vessels from China, Russia, India, Iraq, and Pakistan would be permitted to transit Hormuz β€” reflecting their non-hostile stance toward Iran. India rerouted roughly 70% of crude imports away from Hormuz (up from 55%), absorbing discounted Russian crude via US waivers. India's new VLCC terminal at Mundra Port launched January 2026 to handle non-Hormuz supply at scale.

ISPRL also exploring overseas storage in Oman. India's petroleum ministry confirmed in March 2026 that ~60% of LPG consumption is imported, and ~90% of those imports flow through Hormuz, creating acute domestic fuel security concern.

πŸ“Š Current Affairs β€” India TV News / Fortune / Time Β· June 2026

Bab-el-Mandeb Threat Escalates: As of June 2026, Iran has threatened to extend disruptions to Bab-el-Mandeb. Iranian adviser Ali Akbar Velayati warned the resistance axis "can shut down both Bab al-Mandab and Hormuz." Iran's Parliament Speaker Ghalibaf queried publicly on April 3: "What share of global oil, LNG, wheat, rice and fertiliser transits Bab-el-Mandeb?" β€” seen as signalling intent. The Houthis, who resume attacks as of March 28 (after US–Iranian war reignited), declared the Bab-el-Mandeb "completely closed to the Israeli enemy." Shipping through the Red Sea remains ~60% below 2023 levels (after October 2025 ceasefire only partially restored traffic).

πŸ“Š Current Affairs β€” IEA / Policy Circle Β· 2025–2026

Energy Data Highlights: In 2025, nearly 15 mb/d of crude (34% of global crude trade) passed through Hormuz; China and India combined received 44%. Qatar exported over 112 billion cubic metres of LNG in 2025 (world's top LNG exporter) β€” virtually all via Hormuz. The IEA estimated that 4.2 mb/d of crude oil and petroleum liquids transited Bab-el-Mandeb in H1 2025 (down from 9.3 mb/d in 2023 due to Houthi attacks). India spends USD 26.4 billion/year importing cooking gas (LPG) alone, most shipped through Hormuz. India's strategic reserves cover only about 25 days of crude oil and LPG combined (10 days for LNG) β€” far below the IEA 90-day standard.

πŸ’‘ Exam Tip β€” Why This Matters for Prelims 2026

The 2026 Hormuz crisis is the most significant real-world test of chokepoint theory in decades and is very high probability for UPSC Prelims 2026 current affairs questions. Expect questions on: (1) which nations Iran permitted to transit; (2) Operation Urja Suraksha launch date; (3) India's SPR capacity and locations; (4) the Petroline/Yanbu bypass; (5) Brent crude impact. The dual Hormuz + Bab-el-Mandeb scenario and its "no bypass" character is a top Mains angle.

Current Affairs Summary: Hormuz crisis since Feb 28, 2026 β†’ Iran closed to "unfriendly nations" β†’ India exempted (diplomacy) β†’ $10B/day dual chokepoint risk β†’ India rerouted 70% crude β†’ SPR at 64% fill β†’ Op Urja Suraksha (Mar 23, 2026) β†’ Bab-el-Mandeb under new threat from Houthis + Iran (June 2026).

Statement-Based T/F β€” UPSC Prelims Style
StatementT/FReason / Correction
The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman.βœ… TRUEIt is the sole maritime exit from the Persian Gulf to the open ocean (β†’ Arabian Sea)
Saudi Arabia lies on the southern coast of the Strait of Hormuz.❌ FALSESouthern coast = Oman (Musandam exclave) + UAE. Saudi Arabia has NO coastline on the strait.
The Bab-el-Mandeb Strait connects the Red Sea to the Gulf of Aden.βœ… TRUELocated between Yemen (NE) and Djibouti + Eritrea (SW). "Gate of Tears" in Arabic.
Perim Island in Bab-el-Mandeb belongs to Djibouti.❌ FALSEPerim (Mayyun) Island belongs to Yemen. It lies off Yemen's southwestern coast and divides the strait into two channels.
The Traffic Separation Scheme (TSS) in the Strait of Hormuz lies in Iranian territorial waters.❌ FALSEThe TSS lanes lie in Omani territorial waters, north of the Musandam Peninsula.
Under UNCLOS, the right of transit passage through international straits can be suspended by the coastal state.❌ FALSETransit passage (Articles 37–38) is non-suspendable. This is precisely why Iran's 2026 closure was legally contested.
Iran is a signatory to UNCLOS.❌ FALSEIran has NOT ratified UNCLOS β€” this is why it disputes transit passage rights in Hormuz.
Operation Sankalp was launched in 2019 to protect Indian merchant vessels in the Strait of Malacca.❌ FALSEOperation Sankalp targets the Strait of Hormuz, Gulf of Oman, and Persian Gulf β€” not Malacca. Launched 19 June 2019.
Musandam Peninsula of Oman is contiguous with mainland Oman.❌ FALSEMusandam is an exclave of Oman β€” it is physically separated from mainland Oman by UAE territory.
Qatar can completely bypass the Strait of Hormuz to export its LNG.❌ FALSEQatar has no pipeline bypass. All Qatari LNG exits via Hormuz. Qatar's Ras Laffan LNG terminal is entirely dependent on Hormuz passage.
⚠ Trap 1 β€” Saudi Arabia vs Hormuz

The single most common error: writing Saudi Arabia as a bordering country of Hormuz. Saudi Arabia does NOT border the Strait of Hormuz. The southern coast = Oman (Musandam) + UAE. Saudi Arabia's Red Sea and Persian Gulf coast are entirely separate from the strait.

⚠ Trap 2 β€” Bab-el-Mandeb vs Hormuz Mix-up

Frequently confused in pair-matching questions. Memory trick: Hormuz = Half-Moon (Persian Gulf shaped like a half-moon) connects to Gulf of Oman. Bab-el-Mandeb = Bottom of Red Sea (it's at the southern end of the Red Sea) connects to Gulf of Aden.

⚠ Trap 3 β€” Western vs Eastern Channel of Bab-el-Mandeb

The western channel (26 km wide, deep) is used by large commercial vessels. The eastern channel (only ~3 km wide) is shallow and used only for local traffic. UPSC sometimes reverses this. The island that separates them is Perim (Mayyun) β€” a Yemeni volcanic island.

⚠ Trap 4 β€” Djibouti's Military Bases

Questions ask which countries have military bases in Djibouti. The correct list includes: USA, France, China, Japan, Italy (and India has logistics access). China's base (opened 2017) was its FIRST overseas military base. This is a classic Prelims trap where students undercount or miscredit the nations present.

⚠ Trap 5 β€” "Bypassing Hormuz" via Petroline

Students often state that Saudi Arabia's Petroline allows it to "bypass" all chokepoints. This is partially wrong. Petroline takes oil to Yanbu on the Red Sea β€” but oil still has to exit via Bab-el-Mandeb to reach global markets. Only the UAE's Habshan–Fujairah pipeline truly bypasses Hormuz AND exits directly to the Gulf of Oman, avoiding Bab-el-Mandeb entirely.

πŸ’‘ Exam Tip β€” Pair-Matching Format

UPSC loves pair-matching questions: "Strait β€” Waters it connects." Always memorise: Hormuz = Persian Gulf ↔ Gulf of Oman | Bab-el-Mandeb = Red Sea ↔ Gulf of Aden | Malacca = Andaman Sea (Indian Ocean) ↔ South China Sea | Gibraltar = Atlantic ↔ Mediterranean | Palk Strait = Bay of Bengal ↔ Gulf of Mannar.

Trap Countdown: Saudi Arabia β‰  Hormuz coast | Perim Island = Yemen (not Djibouti) | TSS = Omani waters (not Iranian) | UNCLOS transit passage = non-suspendable | Op Sankalp = Hormuz (not Malacca) | Petroline bypasses Hormuz but NOT Bab-el-Mandeb

MCQ Practice β€” 5 UPSC-Style Questions
1Consider the following pairs (Strait β€” Water Bodies It Connects):
1. Strait of Hormuz β€” Persian Gulf and Gulf of Aden
2. Bab-el-Mandeb β€” Red Sea and Gulf of Aden
3. Strait of Malacca β€” Indian Ocean and South China Sea
4. Palk Strait β€” Bay of Bengal and Gulf of Mannar
How many of the above pairs are correctly matched?
Correct: (b) Only three

Pair 1 is WRONG: Strait of Hormuz connects the Persian Gulf and Gulf of Oman (NOT Gulf of Aden). Gulf of Aden is at the other end, connected via Bab-el-Mandeb. Pairs 2, 3 and 4 are all correct. Classic UPSC trap: swapping Gulf of Oman with Gulf of Aden for Hormuz.
2Consider the following statements about the Strait of Hormuz:
1. The Traffic Separation Scheme (TSS) in the Strait of Hormuz lies in Omani territorial waters.
2. Saudi Arabia lies on the southern coast of the Strait.
3. Iran has not ratified the United Nations Convention on the Law of the Sea (UNCLOS).
4. The Musandam Peninsula of Oman is an exclave separated from mainland Oman by UAE territory.
Which of the statements given above are correct?
Correct: (c) 1, 3 and 4 only

Statement 1 βœ… β€” TSS lies in Omani territorial waters.
Statement 2 ❌ β€” Saudi Arabia does NOT border Hormuz. Southern coast = Oman (Musandam) + UAE.
Statement 3 βœ… β€” Iran has NOT ratified UNCLOS.
Statement 4 βœ… β€” Musandam IS an Omani exclave, separated from mainland Oman by UAE territory.
3Which of the following countries has an interest in Perim Island (Mayyun Island) located in the Bab-el-Mandeb Strait?
Correct: (c) Yemen

Perim (Mayyun) Island belongs to Yemen. It is a Yemeni volcanic island off Yemen's southwestern coast that divides the Bab-el-Mandeb into two channels β€” the wider western channel (26 km, used by large ships) and the narrow eastern channel (~3 km). Djibouti and Eritrea are on the African side of the strait. Somalia has no direct border with Bab-el-Mandeb.
4Consider the following statements about India's Strategic Petroleum Reserve (SPR):
1. The total Phase-1 SPR capacity is 5.33 MMT stored in underground rock caverns.
2. One of the three Phase-1 locations is in Visakhapatnam, Andhra Pradesh.
3. India's SPR at full Phase-1 capacity can cover approximately 90 days of crude oil imports β€” matching the IEA standard.
4. Indian Strategic Petroleum Reserves Ltd (ISPRL) is under the Ministry of Petroleum and Natural Gas.
Which of the statements given above are correct?
Correct: (a)/(c) Statements 1, 2 and 4 β€” Statement 3 is WRONG

Statement 1 βœ… β€” Phase-1 capacity is 5.33 MMT (Vizag 1.33 + Mangaluru 1.50 + Padur 2.50).
Statement 2 βœ… β€” Visakhapatnam (Andhra Pradesh) is one of the three Phase-1 locations.
Statement 3 ❌ β€” At full capacity, SPR covers only ~9.5 days β€” far below IEA's 90-day standard.
Statement 4 βœ… β€” ISPRL operates under Ministry of Petroleum and Natural Gas.
5Operation Sankalp, frequently seen in news, is associated with which of the following?
Correct: (b)

Operation Sankalp was launched on 19 June 2019 by the Indian Navy (not Coast Guard, not multilateral) following attacks on merchant tankers in the Gulf of Oman. It focuses on the Strait of Hormuz, Gulf of Oman, and Persian Gulf. "Sankalp" is Sanskrit for "Commitment." The operation was expanded to the Gulf of Aden in 2023–24 due to Houthi attacks. A separate Operation Urja Suraksha was launched on 23 March 2026 specifically for the 2026 Hormuz crisis.
