It was unrealistic to expect last week’s strong increase in mortgage activity to be sustainable in the current volatile rate environment, and indeed it was not. The Mortgage Bankers Association said its seasonally adjusted Market Composite Index, a measure of loan application volume, which had risen 7.4 during the week ended February 3, ended last week with a decline of 7.7 percent. On an unadjusted basis it was down 7.0 percent. Refinancing had driven last week’s surge, and it led the retreat, falling 13 percent . The index was 76 percent lower than the same week in 2022. The refinance share of applications dipped to 32.0 percent of the total from 33.9 percent the previous week. [refiappschart] The volume of purchase mortgages decreased 6.0 percent on a seasonally adjusted basis and was down 5.0 percent before adjustment. Purchase activity was 43 percent lower than the same week one year ago. [purchaseappschart] “Mortgage rates increased across the board last week, pushed higher by market expectations that inflation will persist, thus requiring the Federal Reserve to keep monetary policy restrictive for a longer time. After five straight weeks of decreases, the 30-year fixed rate increased by 21 basis points to 6.39 percent,” said Joel Kan, MBA’s Vice President and Deputy Chief Economist. “Mortgage applications decreased for the second time in three weeks because of these higher rates. Refinance borrowers, both rate/term and cash-out, remain on the sidelines as current rates provide little financial incentive to act.”
