Global Shipping Chokepoints: Hormuz, Bab-el-Mandeb, Malacca
Maritime chokepoints are naturally narrow passages that channel global trade and energy flows. Disruption at any single point cascades into global inflation, energy crises, and supply-chain breakdowns. For India — the world's 3rd largest oil importer (85% import dependence), 5th largest LNG importer, and a net security provider in the Indian Ocean — these chokepoints are strategic lifelines.
[TOPIC CLASSIFICATION]
Topic type: World Geography + Maritime Security + International Relations
PYQ frequency: High (Prelims 2023, 2021, 2019; Mains 2022, 2020)
Geography: "Gate of Tears" — separates Yemen (north) from Djibouti/Eritrea (south). Connects Red Sea to Gulf of Aden/Arabian Sea.
Traffic: 6.2 mbpd oil (2023); 20,000+ ships/year via Suez. Critical for Europe-Asia trade.
Threats: Houthi attacks (since Nov 2023 — anti-ship ballistic missiles, drones, USVs) on commercial shipping linked to Israel; piracy (2008-12 peak, resurgent 2024); Yemen civil war spillover.
India's exposure: 50% of India's Europe-bound exports transit Suez; 8,000+ Indian seafarers on Red Sea routes; diaspora in Gulf (9 million) evacuation contingency.
India's response: Operation Sankalp extended to Red Sea (INS Kolkata, Kochi, Chennai deployed); multilateral coordination (CMF CTF-153, EU Aspides, US Prosperity Guardian); consular advisories; insurance premium surge monitoring.
Strait of Malacca: The East Asia Artery
Geography: 800 km long, funnel-shaped. Narrowest at Phillips Channel (2.8 km) near Singapore. Separates Sumatra (Indonesia) from Malay Peninsula (Malaysia/Singapore).
Traffic: 94,000 ships/year (2023); 16 mbpd oil (China 80%, Japan 90%, Korea 95% dependence); 30% of India's merchandise trade.
Threats: Piracy (Straits of Malacca and Singapore SOMS — 2023: 18 incidents, down from 2020 peak); congestion (400+ ships/day); haze/smog; territorial disputes (Indonesia-Malaysia EEZ); potential blockade in Taiwan contingency.
India's response: Andaman & Nicobar Command (ANC) — India's only tri-service command; Malacca Straits Patrol (MSP) — Indonesia, Malaysia, Singapore, Thailand coordinated patrols; IFC-IOR (Gurugram) — maritime domain awareness; SAGAR vision — net security provider.
Alternative Routes: Sunda and Lombok Straits
Feature
Sunda Strait
Lombok Strait
Depth
20-50 m (shallow, tidal)
250+ m (deep, VLCC capable)
Width
24 km
35 km
Traffic
15,000 ships/year
10,000 ships/year
Risk
Krakatoa volcanic activity, piracy
Less congestion, longer route (+3 days to NE Asia)
India relevance
ANC monitoring; strategic bypass option
Preferred for Indian VLCCs from Middle East to East Asia
India's Maritime Architecture for Chokepoint Security
Asset
Role
Andaman & Nicobar Command (ANC)
Tri-service command at chokepoint junction (Malacca, Sunda, Lombok); radar chain (COCO Islands), airfields (Campbell Bay, Car Nicobar), submarine berthing
IFC-IOR
Information Fusion Centre - Indian Ocean Region (Gurugram); 50+ partner nations; white shipping agreements (36 countries); real-time MDA
Mission-based Deployments
Continuous IN presence in Gulf of Aden (since 2008), Persian Gulf (Operation Sankalp 2019), East Africa, Malacca Strait
White Shipping Agreements
36 countries + 3 multilateral (IORA, IONS, BIMSTEC) — AIS data sharing for merchant vessel tracking
Coastal Radar Chain
46 stations (mainland + islands) + 6 in partner countries (Mauritius, Seychelles, Sri Lanka, Maldives, Myanmar, Bangladesh)
UPSC Question Themes (Illustrative)
Treat these as original practice prompts unless a linked official UPSC paper is provided; they are not represented as verbatim PYQs.
| Type | Stage | Question |
|------|-------|----------|
| Practice | Prelims | "Which of the following straits connects the Red Sea to the Gulf of Aden? (a) Strait of Hormuz (b) Bab-el-Mandeb (c) Strait of Malacca (d) Suez Canal" |
| Practice | Mains | "The security of India's energy imports is critically dependent on the safety of maritime chokepoints. Discuss the vulnerabilities and India's mitigation strategies." (15 marks) |
| Practice | Prelims | "Strait of Malacca separates: (a) Andaman Sea from South China Sea (b) Java Sea from Indian Ocean (c) Persian Gulf from Gulf of Oman (d) Red Sea from Mediterranean" |
| Practice | Mains | "India's Act East Policy and SAGAR vision converge in the Indo-Pacific. Examine with reference to maritime chokepoints." |
| Practice | Prelims | "Which of the following is NOT a major oil chokepoint? (a) Strait of Hormuz (b) Bab-el-Mandeb (c) Panama Canal (d) Strait of Malacca" |
Statement Elimination Guide
Correct: "Bab-el-Mandeb connects the Red Sea to the Gulf of Aden."
False: "Bab-el-Mandeb is located near the Persian Gulf." (It is 1,500 km southwest of Hormuz)
Trap: "Suez Canal is a natural strait." (False — artificial sea-level canal, 193 km long, opened 1869)
Correct: "Malacca Strait is the shortest route between Persian Gulf and East Asia."
False: "India's crude oil imports mostly transit the Suez Canal." (False — Hormuz to Indian ports direct; Suez is for Europe-bound cargo)
Correct: "Sunda and Lombok Straits are alternative routes to Malacca within Indonesian archipelago."
False: "Panama Canal handles more oil tankers than Malacca Strait." (False — Malacca: 16 mbpd; Panama: limited by draft, ~1 mbpd)
Common Mistakes
Locating Bab-el-Mandeb at Hormuz: They are distinct — Hormuz = Persian Gulf outlet; Bab-el-Mandeb = Red Sea outlet.
Confusing Suez Canal with a strait: Canal is artificial, toll-charged, controlled by Egypt (SCA); straits are natural, governed by UNCLOS transit passage.
Ignoring Sunda/Lombok as alternatives: In Malacca blockade scenario, these are critical bypasses — India's ANC monitors both.
Overlooking the "traffic separation scheme" (TSS): Malacca and Singapore Straits have mandatory TSS under IMO — testable in Prelims map questions.
Missing the India-seafarer angle: 10% of global seafarers are Indian; chokepoint crises = humanitarian + diplomatic crisis.
Current Affairs Hook (2023-24)
Nov 2023 onward: Houthi attacks on Red Sea shipping — 50+ incidents, 4 vessels sunk/seized, Suez traffic down 42% (Jan 2024), freight rates +300%.
Jan 2024: India deployed INS Kolkata, Kochi, Chennai to Red Sea under Operation Sankalp; rescued crew of MV Lila Norfolk (hijack attempt).
2024: IFC-IOR tracked 18,000+ vessels/month; 36 white shipping agreements operational.
2023: Chabahar Port 10-year agreement (Iran) — India's alternative access to Afghanistan/Central Asia bypassing Pakistan; but Hormuz transit still required.
Global: IMO 2024 — new guidelines for Maritime Autonomous Surface Ships (MASS) in chokepoints; UNCLOS transit passage vs innocent passage debates.
