1.4.7. Comments on the model of the Korean Stock Exchange

Each country with its conditions, policies and socio-economic development characteristics will have different market structures. In Korea, with the unified Stock Exchange model to organize and manage the CKPS trading market, only one place organizes and manages the trading of all types of securities, demonstrating professionalism, correctness and rationality, suitable for the level of development and scale of the stock market.

However, regarding the clearing model, on the basis of the Korea Stock Exchange (KRX) taking on this function by establishing a clearing agency (KSD) directly managing the settlement of all transactions on the stock market, the structure of the Korea Stock Exchange (KRX) has become massive, not showing independence and difficult to demonstrate autonomy. Establishing a clearing agency independent of the transaction organization will enhance specialization, standardize the supporting operations completed on the stock market and enhance the ability to control risks related to each operation of different nature.

1.4.8. Lessons learned for Vietnam

1.4.8.1. Transaction organization and management model:

Like most small-scale and underdeveloped stock markets, in order to develop step by step, Ho Chi Minh City Stock Exchange should not establish a subsidiary to organize and manage the options market but should establish an additional board for options trading(similar to the Korean model).

The Ho Chi Minh City Stock Exchange unifies the organization and management of trading of listed options on the Exchange. Trading of options on the Exchange must go through the system of securities companies that are members of the Exchange (all of these companies are currently payment companies). The system of member securities companies performs the basic functions of consulting and brokerage of buying and selling options for customers. At the same time, some companies can act as market makers when meeting the conditions of a market maker.


1.4.8.2. Clearing payment model:

The Korean model does not have an independent depository, but the Korea Exchange (KRX) performs this function through a system of Payment Members, securities depositories and payment banks.

In Vietnam, the Ho Chi Minh City Stock Exchange can study the establishment of a Clearing House under the Department to perform the function of a Clearing House for the options trading market or the Securities Depository Center can be the first choice in performing the function of margin and clearing for options transactions because currently in Vietnam there is an independent Securities Depository Center that is responsible for clearing all transactions on the Vietnamese stock market.

1.4.8.3. Listing, information disclosure and monitoring systems

Depending on the level of development and conditions of each stock market, appropriate regulations are issued.


CONCLUSION OF CHAPTER 1

Chapter 1 presents the most basic issues about options, stock options and the development of the options trading market; as well as the role and significance of applying options to the development of the stock market. The objective of this chapter is to provide basic theory as a foundation for research and learning from the experience of organizing derivatives exchanges in Korea as well as research and application of stock options trading to the Vietnamese stock market in the following chapters.

In addition, in this chapter, the model of organization and management of derivative securities trading at the Korea Stock Exchange, the Korean Stock Exchange is one of the few most developed stock exchanges in Asia, has been described.
