The Strait of Malacca shipping route carried 102,525 vessel transits in 2025, a record, and roughly a quarter of the world’s seaborne trade by value moves through a waterway that narrows to 2.8 kilometres at its tightest point. It is the busiest commercial chokepoint on earth by vessel count, ahead of both Suez and Panama.
This guide covers the verified traffic figures and where they come from, what is actually moving, the physical limits that constrain the corridor, the alternatives and why they go unused, and a distinction that matters commercially: passing traffic is not port access, and the two are routinely confused.

How Much the Strait of Malacca Shipping Route Carries
Traffic counts for this corridor circulate widely and inconsistently, so the source matters more than the number.
The authoritative count comes from the Malaysian Marine Department, drawn from STRAITREP vessel reporting at One Fathom Bank in the north, Iyu Kecil in the south, and the western entrance to the Singapore Strait. On those figures, transits by vessels over 300 gross tonnes reached 102,525 in 2025, the first year above 100,000.
| Year | Transits (over 300 gt) | Change |
|---|---|---|
| 2004 | 63,636 | baseline |
| 2024 | 94,301 | +5.5% |
| 2025 | 102,525 | +8.72% |
That works out to roughly 281 vessels per day, or one every five minutes through the corridor. Traffic on the Strait of Malacca shipping route has risen 61% since 2004, and the growth has been steady rather than cyclical.
On value, estimates vary by methodology. The Center for Strategic and International Studies puts the share of global maritime trade near 22%, while other assessments place global seaborne trade by value at around 23.7%, worth over USD 2.8 trillion annually. Figures in the 25 to 30% range also appear. Anyone citing a single precise percentage for the Strait of Malacca shipping route is being more confident than the underlying data supports.
What Is Actually Moving
The traffic is not uniform, and its composition explains why the corridor matters strategically rather than only commercially. AIS-based analysis of transit patterns breaks the mix into tankers at 29.4%, container ships at 24.1%, bulk carriers at 19.7%, and the remaining 26.8% across general cargo and other types.
Tankers dominating the count is the reason the US Energy Information Administration classes this as the world’s largest oil transit chokepoint. Estimates put crude and petroleum product movement in the range of 15 to 17 million barrels per day, alongside a large share of global LNG traffic, most of it bound for China, Japan and South Korea.
The dependency runs one way. East Asia’s energy security is tied to this corridor to a degree that has shaped naval planning across the region for two decades, which is why the Strait of Malacca shipping route appears in strategic assessments far more often than its commercial statistics alone would justify.
The Chokepoints: Width, Depth and Malaccamax
The Strait of Malacca shipping route runs roughly 890 kilometres between the Malay Peninsula and Sumatra. Its constraints are physical and unforgiving.
- Width. At the Phillips Channel near Singapore, the navigable corridor narrows to about 2.8 kilometres. Roughly 281 vessels a day pass through that gap under vessel traffic services run by Malaysia and Singapore.
- Depth. Charted depths along the main channel run from about 25 metres to 100 metres. Twenty-five metres is adequate for fully laden Very Large Crude Carriers but binding at the top of the fleet.
- Malaccamax. That depth limit produced a named ship class. The Malaccamax design is 330 m length, 60 m beam and 20.5 m draft, and it exists because the strait sets the ceiling. Vessels above it route elsewhere or sail part-loaded. This is the same relationship between depth and vessel economics set out in this guide to what a deep sea port actually is, applied to a waterway rather than a berth.
Congestion is the constraint that grows. Width and depth on the Strait of Malacca shipping route are fixed, while the traffic passing through them is not, and the gap between those two facts is the corridor’s long-term problem.
The Alternatives and Why Nobody Uses Them
Two other passages connect the Indian Ocean to the Pacific through the Indonesian archipelago: the Sunda Strait and the Lombok Strait.
Both are used, and both are marginal. Rerouting adds roughly one to three days of transit, and the Sunda Strait in particular is poorly suited to deep-draft tankers. For a vessel on a fixed schedule, days translate directly into charter cost and missed berth windows.
A Kra Canal across southern Thailand has been proposed repeatedly for over a century and remains unbuilt. The practical position is that the Strait of Malacca shipping route has no substitute at current volumes. That is precisely what makes it a chokepoint rather than merely a busy lane, and why disruption anywhere along it prices into freight and insurance markets within hours.
Security Along the Strait of Malacca Shipping Route
Piracy along this corridor peaked in the early 2000s. In the first half of 2004 alone the strait saw 20 attacks on ships, 30 crew taken hostage and four killed.
International pressure pushed Indonesia, Malaysia and Singapore into coordinated patrols, and the Regional Cooperation Agreement on Combating Piracy and Armed Robbery Against Ships in Asia, known as ReCAAP, was established. Incident rates fell substantially, and the corridor today is a materially safer waterway than it was two decades ago.
Risk has shifted rather than disappeared. Contemporary concern along the Strait of Malacca shipping route centres less on armed robbery than on geopolitical disruption and the concentration exposure of routing a quarter of world trade through a 2.8 kilometre gap. A closure lasting days would reprice freight and insurance globally, and there is no alternative capable of absorbing the volume.
Passing Traffic Is Not Port Access
This is the part most commonly misread, and it is the one with commercial consequences. A vessel transiting the strait is not doing business with the coastline it passes. Of those 102,525 transits, the overwhelming majority call at Singapore, Port Klang, or nowhere at all before continuing. Sumatra faces the strait along more than a thousand kilometres of coast and captures a small fraction of the value moving past it.
Singapore is the demonstration of the difference. Its position on the Strait of Malacca shipping route is geographically ordinary. What converts that position into economic value is depth, terminal capacity, bunkering, customs efficiency, and connectivity, none of which follow automatically from being nearby.
For an industrial operator, the practical translation is straightforward. Traffic volume tells you the corridor is important. It tells you nothing about whether a site on that corridor can actually receive a ship, at what draft, with what handling, and connected to what inland network. Those are separate questions, and the answers are what determine landed cost. In North Sumatra the connectivity half of that equation is examined in this analysis of multimodal transport in the province.
Proximity to a shipping lane is a precondition. It is not an advantage on its own, and any project presenting it as one is skipping the part that matters.
Frequently Asked Questions
How many ships use the Strait of Malacca shipping route each year?
Malaysian Marine Department figures recorded 102,525 transits by vessels over 300 gross tonnes in 2025, the first year above 100,000 and up 8.72% on 2024. That averages roughly 281 vessels daily, making it the busiest commercial chokepoint by vessel count.
What percentage of world trade passes through the strait?
Estimates range from about 22% to 30% depending on methodology and whether measured by value or volume. The Center for Strategic and International Studies puts it near 22% of global maritime trade. Precise single figures should be treated with caution.
What is the narrowest point of the Strait of Malacca?
The Phillips Channel near Singapore, where the navigable corridor narrows to approximately 2.8 kilometres, or 1.7 miles. Vessel traffic services operated by Malaysia and Singapore manage transits through this section, which handles the full daily traffic volume.
What is a Malaccamax vessel?
Malaccamax is the largest vessel size the strait can accommodate, defined by its depth limit: approximately 330 metres length, 60 metres beam and 20.5 metres draft. Vessels exceeding these dimensions must route via the Lombok or Sunda straits instead.
Are there alternatives to the Strait of Malacca shipping route?
The Sunda and Lombok straits both connect the Indian and Pacific Oceans through Indonesia, but rerouting adds roughly one to three days of transit and the Sunda Strait suits deep-draft tankers poorly. A Kra Canal through Thailand has been proposed for over a century without being built.
SIIPE and the Strait
SIIPE (Sumalacca Integrated Industrial and Port Estate) is a planned integrated industrial estate and bulk port development in Medan Belawan, North Sumatra, fronting the Strait of Malacca and situated 4.7 km from Belawan Port. Its own port component is at the planning stage and is not operational.
Consistent with the point above, the estate’s case does not rest on transit volume. Being on the corridor is a starting condition shared with a thousand kilometres of Sumatran coastline. What distinguishes a site is whether it converts that position into usable access: berth depth, plot-to-quay distance, handling capability, and inland connectivity. Belawan’s own specifications and limits are covered in this profile of the port.
Operators assessing northern Sumatra against a specific cargo profile can review industrial land available at SIIPE, or reach the team at info@siipe-port.com or on WhatsApp at +62 811 860 980.
