SMBS

What SMBS does

SMBS (Seoul Foreign Exchange Brokerage Co., Ltd. / 서울외국환중개 주식회사) is Korea's designated inter-dealer broker and official exchange-rate announcer, operating hybrid voice and electronic broking across foreign exchange, derivatives, money market, and bond products for Korean banks, securities firms, and asset managers. Founded in 2000 as a spin-out of the FX brokerage function of the Korea Financial Telecommunications and Settlement Bureau (금융결제원), which remains its 100% state-owned parent, SMBS was established through regulatory approval from the Ministry of Finance and Economy and has since operated under continuous designation by the Ministry of Economy and Finance as the calculator and announcer of Korea's Market Average Rate (MAR) for USD/KRW and CNH/KRW, plus adjusted standard rates for 55–57 currencies.

The company's core technology is the FXSeoul next-generation hybrid broking system, launched in October 2018, which combines voice-based and electronic broking with automated trade matching, confirmation management, and information distribution for FX, F/X swaps, cross-currency pairs, NDF, IRS, CRS, currency swaps, and currency options. In April 2024 SMBS extended its surface with WTS (Web Trading System), a browser-based KRW/USD spot and F/X swap platform that pushed trading hours to 2:00 AM the next day, and the firm has offered an API/SFTP data service since May 2020 for machine-to-machine distribution of standard rates, adjusted rates, and cross-currency rates.

SMBS makes money through two reinforcing streams: brokerage commissions on inter-dealer transactions across FX, derivatives, money market, and bonds, and subscription-based information services (standard rate feeds, mobile and institutional information services, and historical data) redistributed to financial institutions, data vendors such as Reuters and Bloomberg, research bodies, and corporate treasury users. With 2025 operating revenue of KRW 54,573 million, net income of KRW 7,526 million, total assets of KRW 139,387 million, and a 101–250 employee footprint spanning Seoul, Shanghai (since 2017), and London (since September 2025), SMBS combines a regulated domestic monopoly franchise with a measured international expansion, most recently validated by HKMA Approved Money Broker registration in June 2025.
