    Mortgage Rates Breach 7% as Treasury Surge Sinks Homebuilder ETF by 10% in Month

    Question

    Mortgage Rates Breach 7% as Treasury Surge Sinks Homebuilder ETF by 10% in Month

    Direct answer

    The sharp repricing in the US rates complex has transmitted directly into domestic residential borrowing costs, pushing average 30-year fixed mortgage rates above 7% for the first time in more than 24 months. The move creates an immediate affordability hurdle for prospective buyers. Equities tied to home construction have suffered aggressive liquidation, with the sector ETF ITB retreating 9.9% in four weeks. Tier-one homebuilders such as D.R. Horton (DHI), PulteGroup (PHM), and Lennar (LEN) continue to face margin contraction risks from potential rate buydowns and extended selling cycles.
