Strait of Malacca
A vital maritime chokepoint linking the Indian and Pacific Oceans.
The Strait of Malacca is a narrow stretch of water, 900 kilometres long and from 65 to 250 km wide, between the Malay Peninsula to the northeast and the Indonesian island of Sumatra to the southwest. It connects the Andaman Sea (Indian Ocean) and the South China Sea (Pacific Ocean) and is one of the most important shipping lanes in the world, carrying approximately 25% of the world's traded goods and over 35% of oil transported by sea as of 2024.

Lore & Background
The name 'Malacca' is traditionally associated with the Malacca tree (Phyllanthus emblica), also known as the Indian gooseberry tree, and is believed to derive from the local Malay word 'Melaka'. According to historical traditions, Parameswara, a Sumatran prince and founder of the Malacca Sultanate, selected the site for his new kingdom where the city of Malacca now stands, naming it after the tree under which he had rested. Over time, the name came to refer to the strategically significant waterway.
The strait has historically been a contested area. In the 7th century, the Srivijaya empire conquered the region to control the spice trade. Subsequent prosperous states controlling the strait include the Malacca Sultanate, the Johor Sultanate, the British Straits Settlements, and the city-state of Singapore. Early traders from Arabia, Africa, India and Persia reached Kedah before arriving at Guangzhou, using monsoon winds. After the tenth century, ships from China began to trade at eastern ports, and shipping began to use the Strait of Malacca itself as a trade route.
Reader's Guide
The Strait of Malacca is one of the most important shipping lanes in the world, serving as the main shipping channel between the Indian Ocean and the Pacific Ocean. It links major Asian economies including India, Thailand, Indonesia, Malaysia, Philippines, Singapore, Vietnam, China, Japan, Taiwan, and South Korea. Over 94,000 vessels pass through each year (2008), carrying about 25% of the world's traded goods, including oil, Chinese manufactured products, coal, palm oil, and Indonesian coffee. As of 2024, over 35% of oil transported by sea and 20% of gas flows through the strait.
The strait narrows to only 2.8 km wide at the Phillip Channel near southern Singapore, making it one of the world's most congested shipping choke points. The maximum vessel size that can pass is referred to as Malaccamax. The strategic significance has led to security concerns, particularly for China, with Chinese president Hu Jintao coining the term 'Malacca dilemma' in 2003 to describe China's vulnerability to potential disruptions in energy supplies. Modern piracy and smuggling are concerns, and the United Nations Convention on the Law of the Sea has at times heightened tensions due to territorial waters issues.

Frequently Asked Questions
Who is Strait of Malacca?
The Strait of Malacca is a narrow waterway roughly 900 kilometres long, wedged between the Malay Peninsula to the northeast and Indonesia's island of Sumatra to the southwest. It acts as the natural sea bridge joining the Andaman Sea (Indian Ocean) with the South China Sea (Pacific Ocean).
What is Strait of Malacca's role in the world?
It is one of the most heavily used shipping corridors on the planet, routing about 25% of all globally traded goods and more than 35% of seaborne oil as of 2024. In 2008, over 94,000 vessels passed through in a single year, making it a linchpin of international commerce.
How big is Strait of Malacca, and can any ship fit through it?
The channel ranges from 65 to 250 km in width, but its minimum depth is only 25 metres (about 82 feet). That shallow floor restricts the draft of the largest container ships and tankers, so not every vessel in the world can legally transit the strait.
Why do fans call Strait of Malacca a 'chokepoint'?
Because it is the shortest practical sea link between the Indian and Pacific Oceans, trade between East Asia, the Middle East, and Europe has almost no efficient alternative route. Its limited width and depth mean any closure—political, environmental, or military—would send shockwaves through global supply chains almost immediately.
What share of the world's energy actually flows through Strait of Malacca?
As of 2024, the strait carries over 35% of all oil transported by sea and roughly 20% of the world's liquefied natural gas. In fan-encyclopedia terms, it is the single most critical artery for global energy security.
