For many decades, MRB issuers have been able to sell their tax-exempt bond offerings in the municipal market at interest rates below Treasuries. At the same time, mortgages were priced above Treasuries by 150 basis points (1.5%). The MRB spread (mortgage rates subtracting tax-exempt bond rates) was a healthy 150 to 250 basis points (1.5 to 2.5 percent), a positive spread.
That was then.
Starting on October 09 2008, due to the financial crisis, those old relationships changed and were no longer valid. The spread briefly went negative for the first time in the history of the MRB market. Then, starting on November 27 2008 and for 41 weeks until September 10 2009, municipal rates (as indicated by the Bond Buyer 25 Revenue Bond Index) were higher than Treasuries and higher than mortgage rates. That was an unprecedented period of negative spreads, until now. For the past 75 weeks (1 year, 23 weeks), the spread has been negative.
In the past 159 weeks (3 years, 3 weeks) there have been only 31 weeks of positive spreads (see chart).
This week, municipal rates, as indicated by the weekly Bond Buyer 25 Revenue Bond Index, are 5.07 percent (from 5.06 last week). Conforming mortgage rates as indicated by the weekly Freddie Mac Primary Mortgage Market Survey are around 4.11 percent (from 4.12 last week).
Freddie Mac PMMS as of 10/20/2011: 5.07%
Bond Buyer 25 Revenue Index as of 10/20/2011: 4.11%
