Mortgage Delivery to the Secondary Market when Interest Rates are Falling

Research output: Contribution to journalArticlepeer-review

2 Scopus citations


A borrower whose loan is committed to the securitization process has the ability and incentive to switch lenders if market rates drop during the loan origination period, which creates significant exposure for primary lenders. A simple secondary market contract innovation we call a mortgage rate drop guarantee (MRDG) could shift this risk to the securitizers who represent portfolio investors. Our simulation results indicate this shifting would have improved the risk/return distribution faced by originators without damaging the risk/return position of securitizers during our 1977-2010 sample period. Assuming conservative loan lives and origination periods, and competitive lending markets, the risk reduction features of MRDGs could also have generated significant interest savings for borrowers.
