After the financial tsunami in 2008, banking businesses took advantage in the economic recovery to attract investors back. For the past two or three years, financial institutions have generated considerable revenue from wealth management businesses, which was growing at a two-digit rate. Since financial consultants determine the success of customer relation management, which is the key factor to wealth management business, it has become essential for human resource research in banks to investigate the characteristics of financial consultants. This study investigates whether there exists a positive correlation between key factors, such as the financial consultants¡¦ seniority in banking business, developing expertise, work attitude, and organizational climate, and their performance achievement. It is hoped that financial consultants, whether recruited from local branches or from outside of the bank, when equipped with related banking experience, developed expertise, better work attitude and supporting organizational climate can achieve their performance goals. This study is based on questionnaire results from the 172 financial consultants in Bank S. A total of 114 valid questionnaires were returned, yielding a return rate of 66.28%. Statistical analysis shows the following results: 1. There is a significant positive correlation between seniority in banking business, developing expertise, and performance achievement. 2. Higher levels of seniority in banking business and developing expertise, lead to higher levels of performance. Based on the results, this study suggests that for future human resource recruiting and training, the wealth management division should strengthen trainings in financial services provided especially for high net worth clients, in addition to the recruitment of experienced employees from local branches. Competent financial consultants, with required certifications, should provide timely suggestions on stop-loss and stop-gain to clients to secure their trust and recognition. Only when the clients become stable assets of the bank can wealth management business be sustainable.
