This paper examines the unsound sales practices of funds which has being grown rapidly and its trends of complaints and disputes relating to retail fund sales through bank employee briefly. Today funds have offered the best way for investors who have only modest amounts of money to invest to obtain broad diversification and professional management. The largest sale distributor of funds is shown as bank in Korea. In responding to sales rapid growth, the disputes related to retail fund sales are being increased fast. Especially, although the sale of foreign funds is growing fast, the specific risk of investment regarding foreign funds are not explained to the investors in detail and in comprehensive manner. Individual investors are not accustomed to foreign funds which have different risk taste compared with domestic fund, including foreign currency exposure, political risk and so on. This paper briefly reviews the fund sales performance and unsound practices criticised often in recent days and what actions the law has taken to those unsound sales practices and what change newly enacted law will take and what additional actions the newly law should take for the benefit of fund investors. According to the newly enacted law (named as The Capital Market and Investment Service Provider Act), the bank will be treated as investment service provider (broker) and various provisions in the law applies to bank which sells various funds in the house. According to the newly enacted law, especially the duty to explain about the investment risk applies to the bank. If as the investment service provider, bank does not explain the investment risk to the individual investor, they should pay the possible loss of principal amount invested to them. My proposal in this article fells into two basic categories. First, as a regulatory proposal, new regulation specifically should address unsound promotion like strong recommendation and prediction without reasonable basis. Second, bank should improve fund sales practices. Bank management should adopt a framework to ensure compliance with all applicable laws and ensure effective supervision of individuals engaged in sales activities. Regulatory goal should be to enable and encourage investors to make better fund purchase decisions and to enhance the ability of market forces to discipline costs.
