Summary of Market Concentration in Fintech

This paper analyzes market concentration in the U.S. residential mortgage lending industry, with a focus on fintech lenders. The key points are as follows:

Key Insights

1. Market Shift: The study period (2011–2019) showed a significant shift from traditional banks to nonbank lenders, including fintech.

2. Fintech Dominance: Fintech lending is highly concentrated, with top three fintech lenders accounting for 70% of loan originations. Their market share nearly doubled, while banks' market share halved.

3. Technological Impact: Quality improvements in fintech services explain over 50% of the increase in fintech market share and 43% of the rise in fintech concentration. Fintech lenders process applications faster and respond more elastically to demand.

4. Regulatory Considerations: Growing concentration among fintech nonbanks raises concerns, as they likely pose similar systemic risks to banks due to federal guarantees and potential moral hazard.

Model & Data

• Data from HMDA shows aggregate and lender-specific trends.
• A simple imperfect competition model links quality improvements to observed concentration changes, which cannot be fully explained by cost differences alone.

Implications

The trend suggests regulatory scrutiny is necessary to balance efficiency gains with systemic risks. Future research directions include the role of regulatory policy (e.g., capital requirements) and the moral hazard associated with government guarantees for originate-to-distribute models.
