Mortgage rates have reached historic lows in recent months, yet the spread between primary and secondary rates has risen to very high levels, reflecting a number of potential factors affecting originator costs and profits. This paper attempts to evaluate the quantitative importance of some of these factors as background material for the workshop on “The Spread between Primary and Secondary Mortgage Rates: Recent Trends and Prospects” to be held at the Federal Reserve Bank of New York on December 3, 2012.
