We hypothesize and find evidence that banks use venture investments in fintech startups as a strategic approach to navigate fintech competition. We first document that banks’ venture investments have increasingly focused on fintech firms. We find that banks facing greater fintech competition are more likely to make venture investments in fintech startups. Banks target fintech firms that exhibit higher levels of asset complementarities with their own business. Finally, our instrumental variable analyses show that financial investments result in increased probabilities of operational collaborations and knowledge transfer between the investing bank and the fintech investee.
