Fintech in Indonesia is growing very rapidly, this is also very interesting for researchers. This study looks at the effect of Fintech on the performance and risk of conventional banks in Indonesia. The proxy for fintech in this study is P2P lending and the adoption of fintech technology by banks. The number of conventional banks in Indonesia is 107 banks, and this study took a sample of 81 conventional banks. This research period is for 5 years from 2017 to 2021. The results show that P2P lending and fintech adoption do not affect the performance or risk of conventional banks. However, what is interesting about the results of this study is that the interaction between each independent variable with the moderating variable of bank ownership structure shows the results of the influence of the independent variable on the dependent variable which is significant. We find that bank ownership structure is proven to strengthen the effect of P2P lending and fintech adoption on bank risk, while the effect on performance is not significant. We found that the presence of P2P lending will increase the risk of conventional banks. While the effect of fintech adoption shows a lowering effect on bank risk, especially those owned by cooperatives. Our findings support previous research results that the presence of P2P lending will increase bank risk, and the adoption of fintech will decrease risk.
