Mortgage Rate Spike Predicted to Hammer Housing Stocks

Concerns about inflation and US Treasury yields are driving predictions of higher mortgage rates. Selma Hepp, Cotality's chief economist, warns that if inflation reaccelerates, long-term US Treasury yields could increase further, leading to a sharp spike in 30-year fixed mortgage rates to around 9%. This extreme rate environment would severely paralyze housing activity and deepen the affordability crisis.

The three stocks most likely to be hit hard by this scenario are D.R. Horton (DHI), Zillow (Z), and Home Depot (HD). As America's largest homebuilder by volume, D.R. Horton is directly exposed to homebuyer affordability limits. The company has maintained sales momentum over recent years through costly interest rate buy-downs and price incentives. However, if benchmark mortgage rates approach 9%, these concessions would become economically unsustainable, eroding profit margins.

Zillow's core business model relies heavily on transaction velocity within the residential real estate market. A 9% mortgage rate environment would lock existing homeowners into their existing mortgages, drastically restricting inventory and pricing out prospective buyers. This dual contraction in buy-side and sell-side activity would directly curb transaction volumes, reducing revenue across Zillow's high-margin marketplace services.

Home Depot also faces challenges as a result of higher mortgage rates. A sharp increase in mortgage rates would reduce housing turnover, leading to lower demand for pre-sale repairs and post-purchase home renovations. This reduction in discretionary spending on 'big-ticket' structural renovations would create prolonged top-line headwinds for the company.
