We analyze the impact of loan securitization on competition in the loan market. Using a dynamic loan
market competition model where borrowers face both exogenous and endogenous costs to switch
between banks, we uncover a competition softening effect of securitization that allows banks to extract
rents in the primary loan market. By reducing monitoring incentives, securitization mitigates winner’s
curse effects in future stages of competition thereby decreasing ex ante competition for initial market
share. Due to this competition softening effect, securitization can adversely affect loan market efficiency
while leading to higher equilibrium profits for banks. This effect is driven by primary loan market competition,
not by the exploitation of informational asymmetries in the secondary market for loans. We also
argue that banks can use securitization as a strategic response to an increase in competition, as a tool to
signal a reduction in monitoring intensity for the sole purpose of softening ex ante competition. Our result
suggests that securitization reforms focusing exclusively on informational asymmetries in markets for
securitized products may overlook competitive conditions in the primary market.
