Korea's 5 major CEX regimes compared — Upbit / Bithumb / Coinone / Korbit / GOPAX

Overview of Korea’s regime

Under the amended Act on Reporting and Using Specified Financial Transaction Information, Korean virtual-asset service providers file reports with the Korea Financial Intelligence Unit (KoFIU) under the Financial Services Commission (FSC). ISMS certification is one filing condition, and an exchange offering won-denominated trading needs a bank-issued real-name deposit and withdrawal account. A coin-to-coin operator without such an account is not automatically “unregistered.” The banking relationships below are a snapshot of operator and bank disclosures reviewed on 2026-07-29.

Profiles of five won-market operators

The table uses KoFIU / KISA materials and official disclosures by exchanges and banks to identify operating entities and real-name-account partners. It excludes fixed market shares, rankings, and IPO plans. ^[Sources: https://www.kofiu.go.kr/eng/main.do; https://isms.kisa.or.kr/; https://www.kbanknow.com/; https://www.kbstar.com/; https://www.kakaobank.com/; https://www.shinhan.com/; https://www.jbbank.co.kr/.]

For company-specific evidence and updates on operating entities and bank contracts, see the Korean operator pages for Upbit and Bithumb.

Real-name account bank contracts (실명확인 입출금 계정)

A VASP offering won-denominated exchange services must include a bank real-name deposit and withdrawal account in its filing materials. The bank partner is not set by a formal “five major banks” rule; it can change when contracts are made or renewed. Read the table as a dated snapshot.

ISMS-CASP certification

KISA operates the information-security management-system certification used as a VASP filing condition. ISMS-P is a separate integrated privacy certification; this entry does not claim it is mandatory above a KRW 10 billion trading-volume threshold. Certificate validity and KoFIU report acceptance must be checked separately.

International comparison

The table compares only high-level responsible bodies and registration frameworks. It does not reduce Korea to a “single regulator” or Japan to simple “dual supervision.” ^[Sources: https://www.fsc.go.kr/eng/index; https://www.kofiu.go.kr/eng/main.do; https://www.fsa.go.jp/policy/virtual_currency/index.html; https://www.fincen.gov/msb-state-selector.]

Korea’s real-name-account requirement is an important condition for entering the won market, but this entry does not attribute a five-company market structure to legislation alone. Check KoFIU’s latest list for operator counts and filing status.
