How the Strait of Malacca affects the global economy
The Strait of Malacca affects the global economy mainly through oil and energy trade to East Asia. It is the shortest sea route between the Indian and Pacific Oceans and, after the Strait of Hormuz, the world's second-busiest oil transit chokepoint. The EIA estimates that crude oil and petroleum liquids flowing through Malacca averaged about 21.7 million barrels per day in the first quarter of 2025 and 22.8 million barrels per day in the second — a large share of seaborne oil bound for China, Japan, South Korea, and other Asian importers. Because there are few practical alternatives (the main detours, the Lombok and Sunda straits, add distance and cost), perceived disruption risk is associated with higher freight and energy costs for Asia. These are dated EIA quarterly snapshots, manually maintained and not real-time, and tracked alongside many factors rather than as a causal attribution.
- The world's second-busiest oil transit chokepoint after the Strait of Hormuz.
- EIA estimates ~21.7 million b/d (1Q2025) and ~22.8 million b/d (2Q2025) of oil transited (live/source-linked).
- The shortest route between the Indian and Pacific Oceans, vital for East Asian energy imports.
- Few practical alternatives — Lombok and Sunda straits add distance and cost.

At a glance
Source-linked indicators for this topic. Each card shows its source, as-of date, reviewed date, and confidence — manually maintained from cited public sources, not real-time.
Key economic channels
Crude & products supply to Asia
A large share of seaborne oil to China, Japan, and South Korea transits the strait, with limited bypass capacity.
Energy & freight costs
Perceived transit risk is tracked alongside Asian energy and shipping costs; detours add voyage time and fuel.
Trade concentration
Container and dry-bulk flows also concentrate here, linking the strait to broader Indo-Pacific trade.
Latest indicators

Source-linked facts
After the Strait of Hormuz, the Strait of Malacca is the world's busiest oil transit chokepoint by volume, carrying crude and petroleum products toward East Asian markets.
What changed recently
A dated change log for this page, not news.
- DataInitial canonical page with live/source-linked EIA STEO oil-transit estimates for the Strait of Malacca (1Q2025 ~21.7 and 2Q2025 ~22.8 million b/d).
Data confidence & limitations
The strait's strategic role is well established and rated high confidence. The EIA oil-transit volumes are source-linked quarterly snapshots (high confidence as EIA estimates, but ~a year old and recommended for review).
Limitations
- Coverage is partial: the live rows are EIA quarterly oil-transit estimates (1Q–2Q 2025).
- Not real-time; the figures are quarterly snapshots that may be revised by the EIA.
- Oil-transit volume is one metric among several (container and bulk flows are not captured here).
- Not a live vessel tracker; price/freight linkages are associative, not a causal attribution.

Frequently asked questions
- How important is the Strait of Malacca for oil?
- It is the world's second-busiest oil transit chokepoint after the Strait of Hormuz. The EIA estimates about 21.7 million b/d (1Q2025) and 22.8 million b/d (2Q2025) of crude and petroleum liquids transited, mostly bound for East Asia.
- Is this a live shipping tracker?
- No. The figures are dated EIA quarterly snapshots, not real-time, and oil-transit volume is only one of several ways to measure the strait.
