US Housing Starts for September 2025 came in at 1.31 million units, below the consensus estimate of 1.37 million and down from August’s 1.43 million, according to the latest data from the Sigmanomics database. This marks a 8.50% month-over-month decline and a modest 1.40% increase compared to the 12-month average of 1.29 million units recorded in December 2024.

Drivers this month

• Rising mortgage rates pressured builder sentiment and demand.
• Supply chain normalization eased material costs but not enough to offset financing headwinds.
• Regional disparities: The South and West showed resilience, while the Northeast and Midwest contracted.

Policy pulse

The Federal Reserve’s ongoing restrictive monetary policy, with the federal funds rate near 5.50%, continues to weigh on housing affordability. Inflation remains above the 2% target, prompting cautious stance from policymakers. Fiscal stimulus remains limited, with no new housing-specific federal initiatives announced in the past quarter.

Immediate reaction: The US dollar index (DXY) strengthened 0.30% post-release, while 2-year Treasury yields rose 5 basis points, reflecting increased expectations for sustained Fed tightening. The S&P 500 dipped 0.40%, signaling investor concern over slowing housing activity.

Housing starts are a critical barometer of economic health, reflecting builder confidence and consumer demand. The 1.31 million units started in September 2025 remain above the 1.26 million low recorded in June 2025 but are off the peak of 1.50 million units seen in March 2025. This volatility aligns with broader macroeconomic shifts.

Monetary Policy & Financial Conditions

The Federal Reserve’s restrictive stance, aimed at taming inflation, has pushed mortgage rates above 7% for a 30-year fixed loan, dampening affordability. Higher borrowing costs have directly impacted new home construction, as reflected in the recent decline in starts. Tight credit conditions also constrain smaller builders.

Fiscal Policy & Government Budget

Federal housing budgets remain flat, with no new large-scale subsidies or tax incentives introduced this year. State-level programs in the South and West have helped sustain regional construction activity, but the lack of federal stimulus limits broader recovery potential.

External Shocks & Geopolitical Risks

Global supply chain improvements have eased material shortages, but geopolitical tensions in key lumber-exporting regions and energy price volatility continue to pose risks. These factors contribute to cost uncertainty for builders.

Drivers this month

• Mortgage rate increases reduced buyer affordability, lowering builder incentives.
• Material costs stabilized but remain elevated compared to early 2024.
• Labor shortages persist, particularly in the Northeast, slowing project commencements.

Policy pulse

Despite the Fed’s hawkish stance, housing starts have not collapsed, indicating some resilience. However, the gap between actual starts and estimates suggests market expectations may be overly optimistic about near-term growth.

Immediate reaction: The 10-year Treasury yield rose 7 basis points, reflecting inflation concerns tied to housing cost pressures. The US dollar index gained 0.30%, while the Nasdaq Composite fell 0.50%, highlighting tech sector sensitivity to economic growth signals.

Looking ahead, housing starts face a complex interplay of factors. The Federal Reserve’s policy trajectory, inflation trends, and fiscal support will shape the sector’s path. We outline three scenarios for the next 12 months:

Bullish scenario (25% probability)

• Fed signals pause or easing in rates by mid-2026.
• Mortgage rates decline below 6.50%, boosting affordability.
• Federal housing incentives introduced, stimulating demand.
• Housing starts rebound to 1.50 million units by Q2 2026.

Base scenario (50% probability)

• Fed maintains restrictive policy through 2026.
• Mortgage rates stabilize around 7%.
• Housing starts hover near current levels, averaging 1.30 million units.
• Regional disparities persist, with growth concentrated in the South and West.

Bearish scenario (25% probability)

• Inflation surprises to the upside, forcing further Fed hikes.
• Mortgage rates rise above 7.50%, sharply reducing affordability.
• Housing starts fall below 1.20 million units, risking broader economic slowdown.
• Construction sector layoffs increase, impacting labor markets.

Policy pulse

Monetary policy remains the dominant factor. Any Fed pivot could rapidly alter housing market dynamics. Fiscal policy remains a wildcard but currently offers limited support.

Market lens

Immediate reaction: Futures markets price in a 60% chance of a Fed rate hold at the next meeting, reflecting uncertainty. The US dollar and Treasury yields remain sensitive to inflation data and housing reports.

The September 2025 US housing starts report signals a sector under pressure but not collapse. Rising mortgage rates and tight credit conditions weigh heavily, yet regional strength and supply chain improvements provide some offset. The data from the Sigmanomics database highlights the fragility of the current recovery and the critical role of monetary policy in shaping near-term outcomes.

Investors and policymakers should monitor housing starts closely as a leading indicator of economic momentum. The balance of risks suggests a cautious stance, with potential for upside if inflation eases and financing costs decline. Conversely, persistent inflation and further rate hikes could deepen the slowdown.

Overall, housing starts remain a vital signal for the US economy’s health, reflecting consumer confidence, credit conditions, and broader macroeconomic trends.
