Overview

Koscom, formally known as the Korea Securities Computing Corporation, is a South Korean financial technology and financial-market infrastructure company. It was established in 1977 by the then Ministry of Finance and the Korea Exchange to computerize and operate information systems supporting Korea’s securities and futures markets. Rather than functioning primarily as a consumer-facing financial brand, Koscom operates as a technology and systems provider for exchanges, securities firms, financial institutions, public agencies, and professional market participants. The company’s role developed alongside the modernization of South Korea’s capital markets. In its early years, Koscom worked on computer implementation and operating systems for the Korea Exchange and introduced electronic tools for disseminating stock quotations. As trading volumes and the complexity of the Korean market increased, it developed automated trading systems intended to make securities transactions faster, more standardized, and less dependent on manual processing. Its automated stock trading system, introduced in 1988, became an important step in the transition toward electronic market infrastructure. Koscom’s capabilities expanded from exchange operations into a broader set of securities-industry services. These include order routing and matching support, transaction reporting, settlement-related processing, market surveillance and information systems, electronic financial services, digital certificates, security-management infrastructure, and market-data distribution. Its systems support trading in equities, bonds, derivatives, and other financial instruments. It has also provided technology for markets outside South Korea, including trading, clearing, settlement, and bond-market projects associated with exchanges in Malaysia, Laos, and Cambodia. For financial institutions, Koscom has supplied both centralized infrastructure and user-facing tools. Its services have included home-trading systems for securities companies and professional terminals such as CHECKExpert, which provides market news, price quotations, financial information, and real-time market data. The company has also developed broader platforms and services including STOCK-NET, CRS2000, SignKorea, ISAC, and PowerBase. SignKorea reflects Koscom’s role in electronic authentication and digital-certificate services, while PowerBase was positioned as an integrated solution for securities firms. Koscom’s institutional importance is connected to the structure of Korean financial markets. Korea Exchange is its largest shareholder, while a group of securities companies also holds shares. After South Korea opened its financial markets more widely to foreign investors in 1992, Koscom continued developing integrated systems designed to help market participants monitor, analyze, and process capital-market activity. Its platforms have supported listed securities traded through Korea Exchange as well as systems for certain unlisted and over-the-counter instruments. The company’s business is therefore best understood as financial-market infrastructure rather than conventional fintech software sold directly to individual consumers. Its customers and users include exchanges, brokerage firms, institutional investors, government bodies, banks, insurers, and professional traders. Koscom’s positioning centers on reliability, market connectivity, transaction processing, information delivery, security, and compliance-oriented technology. The available reference material does not provide a current revenue figure, detailed present-day corporate structure, or named executive roster, so those fields are left unreported.

History

Koscom was established in September 1977 by South Korea’s Ministry of Finance and the Korea Exchange. Its original purpose was to provide computing and operating capability for the country’s developing securities markets. In April 1978, it began computer implementation and operation work for the Korea Exchange, followed by the introduction of a stock-quotation bulletin-board system in July 1979. During the 1980s, rapid growth in the Korean stock market created demand for an integrated electronic financial system capable of supporting the capital market as a whole. Koscom responded by developing and operating automated systems for securities firms, insurance companies, banks, government agencies, and other financial institutions. Its automated stock-trading system, launched in March 1988, helped move market activity toward electronic order processing and execution. Koscom subsequently broadened its systems to address regulatory and informational requirements. In 1991 it launched STOCK-NET. Following South Korea’s opening of its financial market to foreign investors in 1992, the company developed a foreign-investment-limit management system, introduced in 1994. It also expanded professional market-information services, launching the CHECKExpert terminal in December 1995. CHECKExpert provided brokers and professional investors with market news, quotations, financial databases, securities-company information, and real-time market-data movements. In the late 1990s and early 2000s, Koscom added online trading, authentication, and security capabilities. It launched CRS2000 in 1999 and a home-trading service for securities companies in 1998. The company was authorized as a certificate authority in February 2000 and launched SignKorea digital-certificate services in April of the same year. In January 2001 it opened a Consolidated Security Management Center, supporting its role as a provider of secure financial technology. Koscom also recorded quality and capability milestones, including ISO 9001 and TickIT-related recognition in 1998 and CMMI Level 4 achievement in 2005. From the late 2000s, the company combined domestic financial infrastructure with overseas exchange-technology projects. It launched PowerBase in February 2007 as a total solution for securities firms and received an Asia PKI Best Practice Award that year. In 2008 it built a bond-trading system for Malaysia’s exchange environment and operated a pork-futures trading system. Its international work continued with a trading platform for the Lao Securities Exchange in 2011, a derivatives clearing and settlement system for Bursa Malaysia in 2012, and a trading platform for the Cambodia Securities Exchange in 2012. Koscom’s domestic infrastructure supports trading and related processing for instruments listed on the Korea Exchange, including securities traded in the stock, KOSDAQ, and futures and options markets. Its systems cover functions such as order handling, matching, reporting, and settlement. It has also implemented and operated electronic systems associated with unlisted securities and over-the-counter bond trading. The company’s ownership structure reflects its institutional role: Korea Exchange is the largest shareholder, while several securities firms collectively hold part of the remaining equity. The available reference material does not identify a current chief executive roster, detailed recent corporate strategy, or current financial results. Koscom is therefore documented primarily through its historical market-infrastructure role, named services, and exchange-technology projects.
