How foreign investors can buy Korean stocks

How can a foreign investor buy Korean stocks? Two routes are opening an investment account with a Korean securities firm or using an overseas broker that offers Korean stock trading through an omnibus account.

Foreign investors do not need to register with the Financial Supervisory Service (FSS) before investing in Korean listed securities. The Financial Services Commission’s account-opening rules allow individuals to use passport numbers and corporate investors to use legal entity identifiers, or LEIs.

Choose the account route

To open an account in your own name in Korea, contact a Korean securities firm for its foreign-investor account-opening procedure. For an overseas account, first check whether the broker offers Korean shares to investors in your country of residence. Then ask about account eligibility, required documents, custody and settlement.

An overseas securities firm holds an omnibus account in its own name at a Korean securities firm to trade on behalf of its clients. The FSC’s explanation of this route confirms that clients can trade through a participating overseas broker without opening separate Korean securities accounts themselves. Availability depends on the overseas broker’s arrangements.

To establish the service under the FSC’s omnibus-account guidelines, the overseas broker signs an agreement with a Korean securities firm, opens a custodial account with a domestic standing proxy and then opens the omnibus account. A standing proxy is a representative handling local procedures.

The agreement covers customer due diligence on actual securities holders, transaction records and controls against unfair trading. Using an omnibus account does not remove identification checks on the underlying investor.

Prepare identification and supporting documents

For an individual opening a Korean account, the passport number replaces the need to obtain a new investment registration certificate, or IRC. A foreign company uses an LEI. If your existing account uses an IRC-based identifier, ask the firm whether it needs updating under the authorities’ transition toward LEI-based identification.

Identification numbers and supporting paperwork serve different purposes. A passport number or LEI does not, by itself, complete the firm’s document checks.

For a company with an LEI validated at Level 1, a Korea Securities Depository-issued LEI certificate can serve as its real-name identification document. The official implementation update confirms that this option is in place. Ask the firm about the certificate’s validity and any additional customer due diligence documents.

For corporate applicants whose home-country rules do not require corporate registration, the FSC’s alternative documentation guidance allows an applicant with LEI Level 2 or 3 to submit home-country tax-authority documents instead of the unavailable corporate registration document.

If a representative opens the account, ask whether the firm can verify the power of attorney without notarisation and whether an apostille is required. The market-access roadmap provides conditional relief from notarisation, and the implementation update confirms its introduction. This is separate from the earlier relaxation allowing certain corporate applicants to submit a notarised power of attorney without an apostille. Check which requirements apply to the company, representative and account type.

Arrange funding and currency conversion

Get funding instructions from the firm handling the account route you choose. Before transferring money, check the receiving account, accepted currency, conversion process, charges and payment deadline. Also ask how to withdraw sale proceeds or remit them abroad.

Place the order and complete settlement

Orders reach the Korea Exchange (KRX) through member securities firms. A nonmember intermediary must submit customer orders through a designated member. For background on the markets, see our guide to KOSPI and KOSDAQ.

Under the KRX’s trading procedures, stock trades settle on T+2, the second trading day after execution. Exchange holidays do not count. Each member firm sets its customer settlement deadline. Once a buy order is executed, you must pay for the shares by the deadline set by your broker. For a sale, the settlement obligation is to deliver the securities.

Before placing an order, check with the intermediary whether the security is subject to a foreign ownership restriction. KRX procedures include checks on foreign shareholding caps for certain securities.
