Although liberalization and diversification of the market development has made the financial industry burst with vitality, both factors have also created many severe financial crisis. The risk management process is therefore constantly being reviewed and improved, and our emphasis has shifted from loss management to risk appraisal such as anticipated loss for credit risks, value at risk(VaR) for market risk and so on. How to establish the mechanism of Enterprise Risk Management (ERM) has become the challenge for all financial institutions. The financial authorities demand all banking organizations conform to the Basel Ⅱ regime, which determines how much capital banks should be required to hold and taking account into risks that they take. Therefore we will regard the minimum amount of capital a bank must hold as the risk appetite and then use it to set the level of the market’s risk tolerance. By establishing of VaR limits we can obviously see the effect of the case bank. By surveying the results of our case bank after implement of market risk management, we have reach some conclusions：1, Using RAPM(Risk Adjusted Performance Measurement) to measure the investment performance sill make managers make choices between the reward and risk more efficiently. 2, Understanding of the characteristic of VaR, measuring the correlation between products will promote the efficiency of capital use. 3, Besides the VaR limits of market risk, it still takes credit risk limits and operation risk limits to complete the whole risk management regime. 4. The banks must have a complete capital plan to deal with the unexpected risks.
