Root Cause

The Korea Exchange (KRX) mandates that all foreign investors must register a Foreign Investment Registration Number (FIRN) and use a real-name securities account with a local bank to settle trades; without this, order placement is blocked by the Korea Securities Depository (KSD).

中文

韩国交易所（KRX）强制要求所有外国投资者注册外国投资登记号（FIRN）并使用本地银行的实名证券账户进行交易结算；否则，韩国证券预托院（KSD）将阻止订单下达。

Workarounds

  1. 88% success Register FIRN via a KRX-designated bank (e.g., KB Kookmin) by submitting passport, visa, and proof of overseas address; then open a real-name securities account. Example command for API-based registration: curl -X POST https://api.krx.co.kr/foreign/register -H 'Content-Type: application/json' -d '{"passport":"P12345678","visa":"E-2","address":"123 Main St, Seoul"}'

Dead Ends

Common approaches that don't work:

  1. Attempting to trade via a global broker without FIRN registration 95% fail

    KRX settlement requires KSD registration; global brokers reject orders for KOSPI without FIRN

  2. Using a friend's local Korean bank account as proxy 90% fail

    KSD cross-references investor identity with FIRN; proxy accounts trigger fraud flags and account freeze

  3. Opening a non-resident foreign currency account and trading directly 85% fail

    Non-resident accounts lack securities settlement capability; KRX mandates dedicated investment accounts
