An Unintended Consequence of Mortgage Financing Regulation - A Racial Disparity

This study investigates whether mortgage financing regulation unintentionally leads to minorities paying a higher loan contract rate under a risk-based pricing system. We provide evidence that minority borrowers prepay less frequently than comparable non-minority borrowers and thus have lower termination risk. Racially neutral lending policies prohibit the lender from considering this reduced termination risk, resulting in a disparate impact from the overstatement of a minority borrower's and thus have lower termination risk. While we find little evidence of a rate differential among borrowers under the current regulatory structure, results show minorities pay a higher rate when the variation in termination risk is recognized
