Regulations Governing Foreign Exchange Business of Securities Enterprises Article 23

A securities enterprise that has obtained the qualification to engage in proprietary trading of domestic bonds may also engage in proprietary trading of foreign securities without making an application. However if such trading is neither an investment of proprietary funds nor done to meet hedging purposes, the securities enterprise shall apply to the Bank for approval by submitting documents provided in Article 7 herein and photocopies of the latest CPA audited or certified financial statements, procedures for handling receipt/payment, process description and other documents required by the Bank.
