Coordinates: 4°N 100°E / 4°N 100°E The Strait of Malacca (Malay: Selat Melaka, Indonesian: Selat Malaka; Jawi: سلت ملاک) or Straits of Malacca is a narrow, 550 mi (890 km) stretch of water between the Malay Peninsula (Peninsular Malaysia) and the Indonesian island of Sumatra. It is named after the Malacca sultanate that ruled over the archipelago between 1400 and 1511.
The International Hydrographic Organization defines the limits of the Strait of Malacca as follows:
From an economic and strategic perspective, the Strait of Malacca is one of the most important shipping lanes in the world.
The strait is the main shipping channel between the Indian Ocean and the Pacific Ocean, linking major Asian economies such as India, Indonesia, Malaysia, Singapore, China, Japan, Taiwan, and South Korea. Over 94,000 vessels pass through the strait each year (2008) making it the busiest strait in the world, carrying about 25% of the world's traded goods, including oil, Chinese manufactured products, coal, palm oil and Indonesian coffee. About a quarter of all oil carried by sea passes through the Strait, mainly from Persian Gulf suppliers to Asian markets. In 2007, an estimated 13.7 million barrels per day were transported through the strait, increasing to an estimated 15.2 million barrels per day in 2011. In addition, it is also one of the world's most congested shipping choke points because it narrows to only 2.8 km (1.5 nautical miles) wide at the Phillips Channel (close to the south of Singapore).
