We study the broad question about the sources of FinTech lending growth by examining a specific representative product for which the technologies of both FinTech and the incumbent competitors can be identified and compared—small business lending. We test whether the presence of incumbents employing different technologies affects FinTech penetration, and find more FinTech lending where large/out-of-market banks are more prevalent. Using stress test exposures and Community Reinvestment Act examinations as instruments, we find that FinTech credit more often substitutes for loans by large/out-of-market banks than small/in-market banks. Results are consistent with FinTech advantages in processing hard information, rather than hardening soft information.

Despite surging environmental laws, how their enforcement influences banks' management of climate risks remains underexplored.Using the Brazilian Amazon as a laboratory, we examine the impact of a shock to environmental law enforcement capacity on bank management of risks arising from deforestation-a significant but understudied climate risk.After enforcement declined, Brazilian banks significantly altered their priorities to more short-term profitability over longerterm risk concerns.Banks greatly increased lending to agribusinesses engaged in deforestation and actively shifted resources to regions with higher deforestation potential.Results suggest that without rigorous enforcement, banks may fail to fully internalize deforestation risks, despite existing environmental laws.
