Commercial banks contributes to economic growth in any country and they are expected to yield good financial returns. However, performance of banks in Kenya has been declining. This may be attributed to many factors including risk exposure. This study therefore sought to establish the relationship between number of risk governance mechanisms adopted and financial performance of commercial banks in Kenya. The study is significant to financial institution management, Central Bank of Kenya, Scholars and the government. The target population was all the 42 commercial banks operating in Kenya. The study adopted longitudinal research design covering a period of five years (2013 - 2017). The study used secondary data extracted from annual audited financial statements and reports of commercial banks. Regression analysis and multicollinearity tests were carried out using SPSS. The study found a significant positive relationship between number of risk governance mechanisms and financial performance. From the results, it is established that the number of risk mechanisms adopted by a bank has a positive relationship with the return on assets (a regression coefficient of R=0.191, p=0.011, R2 = 0.036, Adjusted R2= 0.031, p<0.05). The study concludes that, number of risk governance mechanisms have a significant positive relationship with financial performance of commercial banks in Kenya. The study recommends commercial banks to adopt several risk governance mechanisms to manage risk hence improving financial performance.
