Mortgage interest rates rose for the second straight week, and so did the volume of mortgage applications. The Mortgage Bankers Association (MBA) said its Market Composite Index, a measure of that volume, increased 3.3 percent on an adjusted basis from one week earlier and 4.0 percent before adjustment.   The Refinance Index increased 0.5 percent from the previous week and was 11 percent higher than the same week one year ago. The refinance share of activity decreased to 32.1 percent from 33.3 percent the previous week. [refiappschart] The seasonally adjusted Purchase Index was up 5 percent from one week earlier, and the unadjusted version was 6.0 percent higher. Purchasing activity was down 10 percent compared to the same week in 2023. [purchaseappschart]  “Rates increased for the second consecutive week, driven by incoming data indicating that the economy remains strong and inflation is proving tougher to bring down. Mortgage rates increased across the board, with the 30-year fixed rate at 7.13 percent – reaching its highest level since December 2023,” said Joel Kan, MBA’s Vice President and Deputy Chief Economist. “ Despite these higher rates, application activity picked up, possibly as some borrowers decided to act in case rates continue to rise. Purchase applications drove most of the increase but remain at low levels of around 10 percent behind last year’s pace. Refinance applications increased very slightly, driven by a 3 percent gain in conventional applications.”
