I use data on unsecured consumer loans from Lending Club to study how peer-to-peer lending markets respond to monetary policy shocks. I find that both loan supply and demand decrease following unexpected increases in the federal funds rate. The contraction in supply is smallest for risky borrowers, while the decline in demand is largest for these borrowers. In contrast, both demand and supply increase following surprise LSAP contractions, with the increases being largest for risky borrowers. These findings suggest that peer-to-peer lending dampens the effectiveness of monetary policy transmission in unsecured consumer credit markets while increasing risk-taking.
