Putting XBRL to Work in the Mortgage Market

Posted by Robert Kugel on Oct 9, 2012 11:33:42 AM

Unless you have some combination of a very strong credit rating, a high income-to-debt payment ratio and a relatively low loan-to-value ratio, it’s not especially easy to refinance a mortgage these days. That’s a shame, because there are plenty of people who have stayed current in meeting their credit obligations and whose mortgages are comfortably below current market value who could benefit from today’s record low interest rates. One major reason they can’t refinance is the collapse of non-agency mortgage-backed securities (MBS) – that is, those not backed by government agencies such Federal National Mortgage Association, or Fannie Mae – in the wake of the 2008 financial crisis. The crisis, in turn, was caused largely by the collapse in value of mortgage-backed securities. To be sure, a significant portion of the drop in the issuance of non-agency paper is the lack of demand these days for the risky and even fraudulent sub-prime mortgages that were a root cause of the financial collapse. Yet there would be a bigger market for MBSes (and therefore more money available for refinancing) and less need for U.S. government guarantees if there were greater transparency in the quality of the underlying assets of mortgage-backed securities. Technology exists today that would address the transparency issue relatively easily and inexpensively. In particular, eXtensible Business Reporting Language (XBRL) can provide an efficient and relatively inexpensive means of collecting needed information from a large number of disparate parties without requiring them to standardize or modify their systems.
