The island city-state, its hub port and the Strait of Malacca chokepoint

Background

Singapore's Ministry of Foreign Affairs describes the country as "a sunny, tropical island in Southeast Asia, off the southern tip of the Malay Peninsula" and states that "the city-state is 710 square kilometres and inhabited by five million people from four major communities; Chinese (majority), Malay, Indian and Eurasian". It has had a parliamentary democracy "since its independence in 9 August 1965".
The Maritime and Port Authority of Singapore states that "since 1986, Singapore has been the busiest port in the world in terms of shipping tonnage, with an annual average of 140,000 vessel calls" and that it "is the focal point for some 200 shipping lines with links to more than 600 ports worldwide".
On container transhipment the Authority records "over 37.3 million TEU handled in 2022", and port facilities able "to handle over 2,000 containers per vessel, with a turnaround time of less than 12 hours".
The island sits on the Strait of Malacca, which "flows between Indonesia, Malaysia, and Singapore" and "connects the Indian Ocean with the Pacific Ocean through the South China Sea". It is "the shortest sea route between Persian Gulf suppliers and key Asian markets".
The US Energy Information Administration calls it "the second-largest oil trade chokepoint in the world after the Strait of Hormuz", with petroleum and other liquids transiting the Strait reaching 16 million barrels per day (b/d) in 2016.
"At its narrowest point in the Phillips Channel of the Singapore Strait, the Strait of Malacca is only about 1.7 miles wide, creating a natural bottleneck."
If the Strait were blocked, "nearly half of the world's shipping fleet would be required to reroute around the Indonesian archipelago", through the Lombok Strait or the Sunda Strait.

Area of the city-state: 710 square kilometres Date of independence: 9 August 1965 Annual average vessel calls at the port: an annual average of 140,000 vessel calls Shipping lines and ports connected: some 200 shipping lines with links to more than 600 ports worldwide Container transhipment handled: over 37.3 million TEU handled in 2022 Rank of the Strait of Malacca among oil trade chokepoints: the second-largest oil trade chokepoint in the world after the Strait of Hormuz Petroleum and other liquids transiting the Strait of Malacca: 16 million barrels per day (b/d) Width at the narrowest point: only about 1.7 miles wide

Why it matters for exams: The Strait of Malacca is a recurring chokepoint question, and candidates are expected to know both that Singapore commands its eastern end and that the island is a 710 square kilometre city-state with no hinterland of its own.
