Venture Capital Investors, which have recently engaged in financing many startup companies, are divided into two categories viz, independent and bank affiliated investors. In order to measure the effect of venture capitals on bank performance we need to incorporate many financial and economic variables into our analysis. But in the light of complex interrelation between these variables, it is not possible to utilize econometric and classical financial models in this particular case study. As such, we have resorted to a systemic approach and consequently using system dynamic technique to investigate first the effect of bank intervening in venture capital market and in second step to present a comparison between independent and bank affiliated venture capital investors in terms of their performance. The results of this study indicate that with bank intervening in capital market can not only gain profit out of project completion but also expand further venture capital and hence gain more income. In the end, by applying the techniques used in this study one can calculate the amount of venture capital required to optimize bank financial performance.
