A Malacca-Singapore model for resolving Hormuz

1. At a Glance

• The Strait of Hormuz (Iran-Oman chokepoint) carried ~20 million barrels/day of oil in 2024, ~20% of global petroleum liquids consumption, and is currently under strain from regional conflict/siege-warfare conditions [1].
• The Straits of Malacca and Singapore (SOMS) — Indonesia, Malaysia, Singapore as littoral states — offer a working precedent of trilateral cooperative governance under UNCLOS that could inform de-escalation and safe-passage arrangements in Hormuz [3][4].
• UPSC relevance: tests comparative geopolitics of chokepoints, UNCLOS provisions (territorial sea, transit passage, straits used for international navigation), and India's stakes as a major oil-importing and shipping nation [2][4].

2. Why in the News

• Ongoing "siege warfare" in the Strait of Hormuz (2026) has disrupted regional shipping, prompting commentary (The Hindu Business Line, 22 Sept 2026, by M. Kalyanaraman) proposing the Malacca-Singapore cooperative model as a template for resolving the Hormuz impasse [5].
• India's MEA Fact Check Unit debunked social-media claims about Indian tankers paying Iran in Chinese currency to transit Hormuz, indicating active Indian government monitoring of the crisis (March 2026) [1].
• The Indian-flagged LPG tanker Green Asha crossed the Strait of Hormuz safely (April 2026) amid continuing tensions, alongside other LPG/oil carriers (BW Tyr, BW Elm, Pine Gas, Jag Vasant, Jag Ladki, Jag Prakash) delivering over 92,000 tonnes of LPG from UAE/Oman [1].

3. Background & Evolution

• Strait of Malacca: ~800 km long, runs between the Malay Peninsula and Sumatra (Indonesia), connecting the Andaman Sea to the Strait of Singapore [5].
• Strait of Singapore: ~105 km long, connects the Malacca Strait to the South China Sea [5].
• Historically these straits were treated as "international" — akin to high seas, with no territorial claim [5].
• 1957: Indonesia (under President Sukarno) unilaterally declared that waters "surrounding, between and connecting" its islands were Indonesian territorial waters, driven by post-colonial security anxiety and wariness of big-power interference [5].
• 1963: Malaysia-Indonesia armed conflict ("Konfrontasi") over Borneo — yet Malaysia later aligned with Jakarta's maritime stance [5].
• 1971: Indonesia, Malaysia and Singapore jointly asserted claims over the straits, challenging the "international waters" notion during UNCLOS negotiations, with Indonesia insisting on a 12-nautical-mile territorial sea limit [5].
• 1982: UNCLOS finalized, embedding the "Straits Used for International Navigation" regime with right of transit passage (Article 43 basis for strait cooperation) [4].
• 2007: Launch of the Cooperative Mechanism on Safety of Navigation and Environmental Protection in SOMS, institutionalising cooperation among the three littoral states, user states, and stakeholders under UNCLOS Article 43 [3].
• Since the 1970s, the littoral states progressively strengthened coordinated naval patrols and counter-piracy/traffic-management operations [3].

4. Core Static Facts

Feature	Strait of Malacca-Singapore	Strait of Hormuz
Length	Malacca ~800 km; Singapore ~105 km [5]	Narrower chokepoint between Iran and Oman
Littoral/coastal states	Indonesia, Malaysia, Singapore [5]	Iran, Oman (UAE nearby)
Legal regime	UNCLOS "Strait Used for International Navigation" — transit passage under UNCLOS Article 43 [4]	Also a strait used for international navigation; Iran is not a UNCLOS signatory
Cooperative body	Cooperative Mechanism (est. 2007); Co-operation Forum (17th session referenced) [3]	No equivalent standing trilateral mechanism
Traffic share	~25% of world's traded goods pass through SOMS [3]	~20 million b/d oil flow (~20% of global petroleum liquids consumption, 2024) [1]
Territorial sea claim origin	Indonesia's 1957 declaration; 12-nm claim during UNCLOS talks [5]	N/A — different legal posture

5. Multi-Dimensional Analysis

Geopolitical / Strategic

• SOMS model shows that even historically adversarial neighbours (Indonesia-Malaysia post-Konfrontasi) can institutionalise cooperative safety mechanisms once shared economic stakes are recognised [5][3].
• Hormuz lacks an analogous trilateral/multilateral cooperative body involving Iran, Oman, and user states (India, China, Gulf states) — a structural gap the SOMS precedent highlights [3].
• India has direct strategic exposure: continued LPG/crude tanker transits (Green Asha, Jag Ladki, Jag Prakash) show reliance on safe Hormuz passage for energy security [1].

Legal / Constitutional (International Law)

• UNCLOS (1982) transit-passage regime under Article 43 underpins SOMS cooperation — a possible legal scaffold for any future Hormuz arrangement [4].
• Indonesia's unilateral 12-nm territorial sea claim (pre-UNCLOS) demonstrates how littoral states can shape international law through practice before formal codification [5].

Economic

• SOMS carries ~25% of global trade goods; Hormuz carries ~20% of global oil consumption — both are irreplaceable chokepoints where disruption has outsized global economic impact [1][3].
• Indian LPG/oil trade (92,000+ tonnes delivered via multiple carriers) illustrates direct economic stakes tied to Hormuz stability [1].

Historical

• The Malacca-Singapore case is a rare example of former rivals (Indonesia-Malaysia, 1963 Borneo conflict) transitioning to sustained multilateral maritime cooperation — a comparative precedent for adversarial Gulf dynamics [5].

Administrative/Governance

• The Cooperative Mechanism's institutional design (info-sharing, coordinated patrols, stakeholder/user-state involvement) offers a replicable administrative template, though Hormuz's unresolved sovereignty/security disputes make direct transplantation difficult [3].

6. Recent Developments (last 12-18 months)

• March 2026: MEA Fact Check Unit rebutted disinformation about Indian tankers paying Iran in yuan to transit Hormuz [1].
• April 2026: Indian-flagged LPG tanker Green Asha crossed Hormuz safely despite tensions; other carriers (BW Tyr, BW Elm, Pine Gas, Jag Vasant, Jag Ladki, Jag Prakash) continued shipments from UAE/Oman [1].
• 2026 (ongoing): "Siege warfare" conditions in Hormuz reported, prompting the Malacca-Singapore comparative analysis (The Hindu Business Line, 22 Sept 2026) [5].
• 17th Co-operation Forum (Singapore): Indonesia, Malaysia, Singapore reaffirmed commitment to keep SOMS free, open and safe for international shipping under UNCLOS [3].

• Sukarno was the Indonesian President who pursued the assertive 1957 maritime claim [5].

8. Why Hormuz Cannot Simply Copy Malacca

• In Malacca, no coastal state ever wanted to shut the strait. In Hormuz, the threat of shutting it is the whole point.
• Indonesia, Malaysia and Singapore earn money from the traffic. Ports, pilotage, bunkering and trade all depend on ships moving [3].
• So all three had the same goal: keep the water open. Cooperation was the cheapest way to get it [3][4].

• Iran's leverage over the West works the other way. The power to stop traffic is the bargaining chip. A body whose job is to guarantee free passage would take that chip away.

• UNCLOS Article 43 asks states to cooperate 'by agreement' — it cannot force anyone to sit down.

• Article 43 says bordering states and user states should cooperate on navigation aids and pollution control [4].
• It creates no duty to join anything. SOMS worked because three governments chose to build the Cooperative Mechanism in 2007 [3].

• Iran signed UNCLOS but never ratified it. So it is not bound by the treaty's transit passage rules the way the SOMS states are.

• Malacca's threat was criminal; Hormuz's threat is military.

• Coordinated patrols work against pirates, who are small, armed groups avoiding warships [3].
• They do not work against a state navy, mines or missiles. The same toolkit does not transfer.

9. Who Pays to Keep a Strait Safe, and Who Rides Free

• The Malacca model runs on donations, not on dues.
• Lights, buoys and wreck removal in SOMS are funded through an Aids to Navigation Fund [4].
• The money is voluntary. Main givers include China, Japan, Greece, Republic of Korea, Saudi Arabia, the UAE, the Nippon Foundation and Middle East Navigation Aids Services [4].

• Everyone else uses the strait for free. About 25% of world traded goods pass through it [3], but only a handful of user states pay.

• This is the weak joint in any Hormuz copy.

• If safe passage is a free good, no user state has a reason to pay for it. Each waits for the others.

• In Malacca the three littoral states absorbed that cost because their own economies gained. Iran and Oman have no such trade upside from tanker transit to pay against.

• India is a large user of both straits but is not among the named SOMS donors [4].

• Joining the Aids to Navigation Fund would be cheap and would give India a seat at the Co-operation Forum table [3].
• It would also make India's case stronger if it ever asks for a similar arrangement in the Gulf.

10. Malacca's Own Record Is Getting Worse, Not Better

• The 'model' strait is seeing more attacks, not fewer.
• In the first three months of 2025, reported piracy and armed robbery at sea rose by 47.5% over the same months of 2024 [8].
• Asia's incidents nearly doubled, and the Straits of Malacca and Singapore were a main site of that rise [8].

• So SOMS has not solved sea crime. It has managed it, with the numbers moving up and down.

• What is fair in the other direction: even with this rise, ships kept moving and no state closed the strait. That is the real achievement, and it is the part Hormuz lacks [3].

• Exam takeaway: write SOMS as a traffic-management and funding success, not a security success. Claiming it ended piracy is factually wrong [8].

11. What India Changed After Hormuz, and What It Still Has Not

• Crude oil: real movement.
• Before the crisis, roughly 45-50% of India's crude came through Hormuz. Now about 70% of crude arrives on routes that avoid the strait, against about 55% earlier [6].
• Russia now supplies about 40% of India's crude, and India buys from around 40 countries [6].

• Venezuela rose to among India's top suppliers in August 2026 as West Asian supply was hit [6].

• LPG: almost no movement.

• India imports about 60% of the LPG it uses, and about 90% of that comes through Hormuz [7].
• LPG is cooking gas. A cut here hits PMUY households directly, not just refinery margins.

• India began buying LPG from the United States to fill the gap [9].

• Why LPG is harder than crude

• Crude can be bought from any producer and shipped to the same refinery.

• LPG needs pressurised or refrigerated ships and matching import terminals. You cannot switch supplier without the port equipment to receive it [9].

• What the government should do next

• Ministry of Petroleum and Natural Gas should extend the strategic reserve idea from crude to LPG. India stores crude underground at Visakhapatnam, Mangaluru and Padur; there is no equal cushion for cooking gas [7].
• Build west-coast LPG receiving capacity for non-Gulf cargoes, the same way US LPG purchases were arranged after the crisis [9].

15. Common Errors / Trap Areas

• Confusing Strait of Malacca (800 km, Sumatra-Malay Peninsula) with the Strait of Singapore (105 km, separate but connected waterway) — they are often treated as one but are legally/geographically distinct [5].
• Assuming SOMS littoral states number two (Indonesia-Malaysia); the correct count is three — Indonesia, Malaysia, and Singapore [5].
• Mixing up the 1957 Indonesian declaration (unilateral territorial claim) with the 1971 joint claim by all three states — these are sequential, distinct events [5].
• Assuming Iran is a UNCLOS signatory like Indonesia/Malaysia/Singapore — Iran has signed but not ratified UNCLOS, altering the legal comparability of any Hormuz mechanism.
• Attributing MEA's Hormuz fact-check purely to routine diplomacy rather than recognising it as part of a broader disinformation-management function during active regional conflict [1].
