US housing starts declined unexpectedly in August to a seasonally adjusted annual rate of 1.239 million, missing the consensus estimate of 1.35 million by 8%. This marks the second straight month that housing starts have fallen short of expectations. The drop was attributed to a decrease in both single-family construction, which slid to 808,000 units, and multifamily projects, which fell to approximately 421,000 units, with both segments experiencing double-digit year-over-year declines.
The persistent weakness in housing starts is largely due to rising mortgage rates, which are now nearing 6.8%. The 30-year fixed mortgage rate currently stands at 6.76%, a 41 basis point increase from a year ago. This increase has priced out many potential homebuyers; for instance, a $520,000 loan now costs roughly $3,376 a month before taxes, making homeownership unaffordable for millions of middle-income buyers and negatively impacting builder demand.
Despite the decline in starts, building permits showed a modest increase, rising 5% month-over-month to 1.443 million. However, analysts caution that rising permits do not necessarily signal an immediate rebound in construction, as permits are an option to build rather than a commitment. Builder confidence remained low at 35 in August, marking the 16th consecutive month below the neutral 50 mark, indicating continued caution in the sector due to elevated borrowing costs and market uncertainty.
The implications of these continued declines are significant. Fewer new homes being built will exacerbate the existing severe US housing shortage, likely keeping home prices elevated even if interest rates eventually decline. Homebuilder ETFs, such as ITB, saw a 1.1% drop, nearing their 52-week lows, while major homebuilders like D.R. Horton (DHI) and Lennar (LEN) fell 1-2% after cutting their 2026 guidance, reflecting bearish sentiment across the industry.
