Mortgage applications decreased 0.1 percent from one week earlier, according to data from the Mortgage Bankers Association's (MBA) Weekly Mortgage Applications Survey for the week ending September 13, 2019. Last week's results included an adjustment for the Labor Day holiday.

The Market Composite Index, a measure of mortgage loan application volume, decreased 0.1 percent on a seasonally adjusted basis from one week earlier. On an unadjusted basis, the Index increased 10 percent compared with the previous week. The Refinance Index decreased 4 percent from the previous week and was 148 percent higher than the same week one year ago. The seasonally adjusted Purchase Index increased 6 percent from one week earlier. The unadjusted Purchase Index increased 16 percent compared with the previous week and was 15 percent higher than the same week one year ago.

"The jump in U.S. Treasury rates at the end of last week caused mortgage rates to increase across the board, with the 30-year fixed-rate mortgage climbing to 4.01 percent - the highest in seven weeks," said Joel Kan, MBA's Associate Vice President of Economic and Industry Forecasting. "Refinancing activity dropped as a result, driven solely by conventional refinances."

Added Kan, "The purchase index increased for the third straight week to its highest reading since July. Additionally, the average loan amount on purchase applications increased to its highest level since June. This is a likely a sign that the underlying demand for buying a home remains strong, despite some of the recent volatility we have seen."

The refinance share of mortgage activity decreased to 57.9 percent of total applications from 60.0 percent the previous week. The adjustable-rate mortgage (ARM) share of activity decreased to 5.0 percent of total applications.

The FHA share of total applications increased to 10.9 percent from 9.3 percent the week prior. The VA share of total applications increased to 12.7 percent from 11.9 percent the week prior. The USDA share of total applications increased to 0.6 percent from 0.5 percent the week prior.
