Mortgage activity rose significantly during the week ended January 5, but it faced a pretty low bar. Loan application numbers were adjusted to account for the New Year’s holiday on the first day of the week and measured against the four days of Christmas Week. The Mortgage Bankers Association (MBA) said its Market Composite Index, a measure of mortgage loan application volume, increased 9.9 percent on a seasonally adjusted basis compared to the prior week and was 45 percent higher without adjustments. [refiappschart] The holiday-adjusted Refinance Index rose 19 percent from the previous week and 53 percent on an unadjusted basis. The two versions were 30 percent and 17 percent higher year-over-year. Refinancing accounted for 38.3 percent of total applications, up from 36.3 percent the previous week. [purchaseappschart] The seasonally adjusted Purchase Index gained 6 percent for the week and was 40 percent higher on an unadjusted basis, but activity still lagged the same week in 2023 by 16 percent.   “Despite an uptick in mortgage rates to start 2024, applications increased after adjusting for the holiday,” said Joel Kan, MBA’s Vice President and Deputy Chief Economist. “The increase in purchase and refinance applications for both conventional and government loans is promising to start the year but was likely due to some catch-up in activity after the holiday season and year-end rate declines. Mortgage rates and applications have been volatile in recent weeks and overall activity remains low. ”
