We study the effect of cryptocurrency markets on borrowers in peer-to-peer (P2P) lending markets. By using the combined data from both markets during the period January 2017 to February 2018, we provide several novel findings. Our results indicate that the growth in cryptocurrency markets is associated with a large amount of loan requests in the P2P market. This complementarity is strong for borrowers who have good credit grades and are likely to have further knowledge of and might use the borrowed money for investing in the cryptocurrency market. The growth in cryptocurrency markets is further associated with a low default rate, a low interest rate, a high full-funded probability, and a short time required to meet the borrowing goal. These findings are also confirmed by our additional tests using exogenous natural shocks with propensity score matching. Overall, our study highlights the potential of the P2P lending market as a funding source for investment in the cryptocurrency market, especially for high-creditworthy investors who likely have a low entering cost into the cryptocurrency market. Implications for both cryptocurrencies and P2P markets are discussed.
