The story

Under the 1912 Straits Settlements Port Ordinance, the Singapore Harbour Board was formed on 1 July 1913. On 1 April 1964, the Port of Singapore Authority came into being under the 1963 Port of Singapore Authority Ordinance to replace the Singapore Harbour Board and several organisations that have been operating in the port.

In the 1970s, PSA started building a container port in Singapore, and in 1972, handled their first container ship. A decade later, they reached the milestone of one-million-TEU of number of containers processed. They later reached the 5 million TEU mark by 1990, making Singapore the world's largest container port at the time. The company became a global operator after it first started its global expansion in 1996 through port interests in Dalian, China.

A parliamentary bill was passed on 25 August 1997, to turn the Port of Singapore Authority, a state organisation into an independent commercial company. PSA Corporation Limited was thus corporatised on 1 October 1997. The company kept the initials "PSA" as its brand name but it is no longer an acronym. The regulatory functions of the former authority were transferred to Singapore's new maritime regulator, the Maritime and Port Authority of Singapore (MPA).

In order to focus on its core port business, PSA Corporation set up The HarbourFront Limited (present day Mapletree) on 7 December 2000, to spearhead development of its properties.

Following a restructuring exercise in December 2003, PSA International Pte Ltd. became the holding company for the PSA Group of companies.

In March 2022, it was announced by PSA International and Halifax Port Authority that PSA has acquired the Fairview Cove Container Terminal (Ceres Halifax Inc.) from Nippon Yusen Kabushiki Kaisha.
