For the week ending October 23, 2026, the US MBA Refinance Index rebounded slightly to 516.8 from the previous value of 503.1. Benefiting from the 30-year fixed mortgage rate falling for two consecutive weeks, not only did refinancing activity warm up, but overall home purchase applications and the share of adjustable-rate mortgages (ARMs) also saw growth. However, compared to the ultra-low rates currently held by most homeowners, current borrowing costs remain high, limiting the momentum for a full market rebound.
