- Housing starts fell 5.2% in September to an annualised 1.22 million, a four-month low that trailed every estimate in a Bloomberg survey. The figure deserves scepticism: the government reports 90% confidence that the monthly change lay between a 17% decline and a 6.6% gain, a range that includes zero.
- The less noisy series tell a consistent story. Single-family building permits, which lead construction, fell to their lowest since early 2023, while single-family completions dropped to the weakest pace in more than six years. Builder sentiment has slumped to a 14-year low.
- Both sources of future supply are now constrained. Permits at a three-year low mean less building ahead, completions at a six-year low mean less inventory arriving now, and existing-home supply is limited by owners holding low-rate mortgages who only sell when circumstances force it.
- Housing is subtracting from growth directly. Sluggish construction has weighed on the economy in five of the last six quarters, and the Atlanta Fed’s GDPNow model had residential investment declining at an annualised 1.3% in the third quarter before this release.
What Happened?
Multifamily starts, which are volatile month to month, fell nearly 7%. Single-family starts in the South, the largest homebuilding region, dropped to their lowest since January and also declined in the West and Midwest. Mortgage rates have reached 7.5% with the purchase slump now in its sixth week, and builders may be reluctant to start new homes before working through existing inventory.
Why It Matters?
Monthly housing starts are among the noisiest series the government publishes, and the confidence interval here makes that explicit. Reporting a 5.2% decline when the data cannot rule out a 6.6% increase is a reason to look elsewhere, and the corroborating indicators are both clearer and more informative. Permits are a decision to build taken by people with capital at stake, completions are a physical count, and builder sentiment is a survey of the same decision-makers. All three point down, and none depends on seasonal adjustment of a volatile monthly figure. The supply picture is the part that matters for prices. Existing-home inventory is at a decade high in months of supply, yet median prices still rose 1.3% year on year, because owners with low-rate mortgages list only when they must and are not distressed sellers. New construction was the other potential source of inventory, and permits at a three-year low mean it is contracting. Anyone expecting prices to fall needs supply from somewhere, and both channels are now constrained by the same high rates that are suppressing demand. That is why a frozen market can persist rather than resolving. The growth arithmetic deserves attention a week before the Federal Reserve meets. Residential investment has weighed on output in five of the last six quarters and is forecast to subtract again, so housing is acting as a direct drag while fuel costs push headline inflation to 3.7%. The committee faces weakening activity in a rate-sensitive sector alongside supply-driven price pressure, which is the configuration that makes rate decisions genuinely difficult.
What Next?
Permits are the series to follow rather than starts, and a further decline would confirm the construction pipeline is shrinking. Watch builder sentiment, which at a 14-year low is back near levels from the recovery after the financial crisis. The 10-year Treasury at 5.09% determines mortgage pricing with a lag, and any sustained decline would be the first relief in two months. The Federal Reserve meets October 27 and 28 with housing contributing negatively to growth.
