Refinancing activity spiked during the week ended May 11, rising 13.0 percent from the previous week's level according to the Weekly Mortgage Applications Survey released this morning by the Mortgage Bankers Association (MBA).   Refinancing represented 74.9 percent of all applications compared to 72.1 percent the previous week.  The increase drove the Market Composite Index, a measure of mortgage application volume, up 9.2 percent on a seasonally adjusted basis and 8.7 percent unadjusted from the week ended May 4. 

Refinancing more than offset a 2.4 percent dip in both the seasonally adjusted and the unadjusted Purchase Indices on a weekly basis. The unadjusted index was 1.0 percent lower than during the same week in 2011.

The four week moving averages for all indices were up.  The Market Index rose 1.77 percent, the seasonally adjusted Purchase Index 1.57 percent, and the Refinance Index 1.88 percent. 

"A flare up of the sovereign debt troubles in Europe once again led investors to flee to the safety of US Treasury securities last week.  As a result, mortgage rates have reached new lows in our survey, and refinancing application volumes picked up substantially as a result," said Michael Fratantoni, MBA's Vice President of Research and Economics.  "Survey participants indicated that this was not due primarily to HARP volume - the HARP share of refinances fell to 28 percent of refinance applications, down relative to last week and last month, when the share was just above 30 percent in April.  The increase in refinance activity last week was concentrated in the conventional sector, which was up around 14 percent for the week, while government refinance applications were up only 4 percent."Every fixed rate covered by MBA established a new record low during the week and the effective rate of most loans was also down.  The average contract interest rate for 30-year fixed-rate mortgages (FRM) with conforming loan balances ($417,500 or less) dropped to 3.96 percent from 4.01 percent, with points decreasing to 0.37 from 0.41.

The average contract interest rate for 30-year FRM with jumbo loan balances (greater than $417,500) decreased 9 basis points to 4.20 percent with points remaining unchanged at 0.36.

The rate for 30-year FHA-backed FRM fell to 3.75 percent from 3.81 percent, with points increasing to 0.66 from 0.45. This was the only product for which the effective rate increased.

The 15-year fixed-rate mortgage rate decreased to 3.26 percent from 3.29 percent, with points increasing to 0.41 from 0.32.

The average contract interest rate for 5/1 adjustable rate mortgages (ARMs) decreased to 2.80 percent from 2.83 percent, with points increasing to 0.37 from 0.36.  Applications for all  types of ARMs accounted for 5.4 percent of application volume, down from 5.7 percent. 

All rates quoted are for loans with an 80 percent loan-to-value ratio and points include the origination fee.

During the month of April, the investor share of applications for home purchase was at 5.7 percent, unchanged from March.  The Pacific region has the largest investor share of applications for home purchase at 9.5 percent. In addition, the share of purchase mortgages for second homes decreased to 5.7 percent in April from 5.8 percent in March.

The Mortgage Application Survey covers over 75 percent of all U.S. retail residential mortgage applications, and has been conducted weekly since 1990.  Respondents include mortgage bankers, commercial banks and thrifts.  Base period and value for all indexes is March 16, 1990=100.
