Overview
The National Stock Exchange of Australia, commonly known as the NSX, is an Australian securities exchange headquartered in Sydney, New South Wales. It provides a regulated market on which Australian and overseas companies can seek admission and trade their securities if they satisfy the exchange's listing rules. The exchange is operated by NSX Limited, a company whose shares were admitted to trading on the Australian Securities Exchange in January 2005. The institution traces its origins to the Newcastle Stock Exchange, which was formed in 1937 and formally recognised under legislation in 1939. In its earlier history, the Newcastle exchange served local and regional businesses and at various points listed as many as 300 companies. Some former issuers later became substantial Australian businesses, including Golden Circle and Ricegrowers, whose consumer brand is SunRice. Trading activity was suspended during the Second World War, resumed in 1947, and eventually ceased in 1985. The exchange was re-established in 2000. Its revival created a national alternative market for companies seeking a listing outside the dominant Australian exchange. In 2005, NSX Limited acquired the Bendigo Stock Exchange, adding the operation that later became known as the IR Plus Securities Exchange. The following year, the Newcastle Stock Exchange received approval to adopt the National Stock Exchange of Australia name. Although the legal and trading identity changed, the acronym NSX was retained. The NSX has also operated or acquired specialist markets. In cooperation with the Victorian Taxi Directorate, it established a publicly tradeable taxi-licence market in 2006, allowing taxi licences and temporary transfers to be traded. A related National Licence Exchange was intended to extend the model nationally, although the taxi-market operations ended in 2011. In 2007, NSX Limited acquired The Water Exchange, a platform for trading permanent and temporary Australian water entitlements. That business was sold to Envex Water Limited in 2010. Trading on the NSX is electronic and follows time-and-price priority. Its electronic market infrastructure uses NETS, based on the NASDAQ OMX X-stream trading platform. Securities settlement is generally electronic through the ASX Settlement and Transfer Corporation's CHESS system on a T+2 basis, while manual settlement may be available for securities that are not enrolled in CHESS. The exchange's business therefore combines listing services, secondary-market trading, market infrastructure and related specialist-market capabilities rather than functioning as a conventional consumer-facing product brand. The NSX relocated its office and operations to Sydney in 2016. Its positioning is that of an alternative Australian listing venue for companies and investors, with electronic execution and access to a regulated exchange framework. Public reference material does not establish a specific founding individual, current executive roster, ownership percentage, or a complete current issuer count, so those details are left unspecified here.
History
The National Stock Exchange of Australia developed from the Newcastle Stock Exchange, a regional Australian securities market established in 1937. The Newcastle exchange was formally recognised under legislation in 1939. Its early role was to provide a venue for local and regional companies to raise capital and trade their securities. Over time it listed a substantial number of businesses, reportedly reaching as many as 300 issuers. Companies associated with its historical listings included Golden Circle and Ricegrowers, the business behind the SunRice consumer brand. In 1940, J. J. Price, then chairman of the Newcastle Stock Exchange, suspended meetings until after the Second World War. Meetings resumed in 1947. The exchange continued operating for several decades, but its meetings ceased in 1985. It was subsequently re-established in 2000, creating the basis for the modern NSX and its attempt to operate as a national alternative to Australia's principal exchange. A major expansion occurred in 2005 when NSX Limited acquired the Bendigo Stock Exchange. The acquired market had facilitated trading in securities connected with Bendigo Bank's Community Bank branches through an uncertificated market. It was later renamed and repositioned, eventually becoming known as the IR Plus Securities Exchange. The transaction broadened NSX Limited's exchange operations beyond the original Newcastle-based market. On 20 December 2006, the Newcastle Stock Exchange received approval to change its name to the National Stock Exchange of Australia. The new name reflected the exchange's national ambitions, while the NSX abbreviation was retained. The exchange lists companies from Australia and other countries that meet its listing rules and operates an electronic market based on time-and-price priority. NSX Limited also pursued specialist-market opportunities. Working with the Victorian Taxi Directorate, it created the first publicly tradeable taxi-licence market, which began trading on 28 March 2006. The market supported trading in taxi licences and temporary transfers. A National Licence Exchange extended the concept on a national basis, but the taxi-market operations ceased in 2011. In October 2007, NSX Limited acquired The Water Exchange. That platform supported trading in permanent and temporary water entitlements within Australia, giving the group an exchange-related presence in an important natural-resource market. In December 2010, NSX Limited announced the sale of The Water Exchange to Envex Water Limited. The NSX's core market infrastructure is electronic. Its NETS system is based on the NASDAQ OMX X-stream trading platform, and settlement is generally available through the ASX Settlement and Transfer Corporation's CHESS system. The standard settlement cycle is T+2, with manual arrangements available for securities outside CHESS. In 2016, the exchange relocated its office and operations to Sydney. Public reference material identifies NSX Limited as the operator and records its Australian Securities Exchange listing in 2005, but does not provide a sufficiently complete current executive, ownership or financial profile for inclusion.
