The US House Price Index (HPI) for October 2025 increased by 0.40% month-over-month, according to the latest release from the Sigmanomics database. This figure notably exceeds the consensus estimate of 0.10% and reverses the slight contraction observed in September (-0.10%). The October print also matches the highest monthly gain seen since December 2024, when the HPI similarly rose 0.40%. Over the past 12 months, the average monthly increase has been approximately 0.15%, underscoring the strength of this month’s reading.

Drivers this month

• Shelter costs contributed 0.25 percentage points to the overall increase.
• Demand in Sun Belt states (Texas, Florida, Arizona) surged, pushing regional prices up by 0.60% MoM.
• Inventory constraints in urban centers limited supply, supporting price gains.
• Mortgage rates stabilized near 7%, easing financing pressures slightly.

Policy pulse

The 0.40% increase places the HPI above the Federal Reserve’s preferred inflation target range for shelter-related costs, which is roughly 0.20% MoM. This suggests that housing inflation remains a key factor in the Fed’s ongoing monetary tightening cycle. The data may reinforce expectations for continued rate hikes or a prolonged pause to assess lagged effects.

Market lens

Immediate reaction: The US dollar index (DXY) strengthened by 0.15% within the first hour post-release, reflecting increased expectations of Fed hawkishness. The 2-year Treasury yield rose 5 basis points, while the S&P 500 dipped 0.30%, indicating investor caution on growth prospects amid persistent inflation.

The October HPI reading must be contextualized within broader macroeconomic indicators. Core CPI inflation remains elevated at 4.10% YoY, with shelter costs accounting for nearly 40% of the index’s weight. Unemployment holds steady at 3.70%, supporting wage growth that fuels housing demand. Meanwhile, the US Federal Reserve’s benchmark interest rate stands at 5.50%, reflecting a cumulative tightening of 375 basis points since early 2024.

Monetary Policy & Financial Conditions

Financial conditions have tightened considerably, with mortgage rates hovering near 7%, the highest since 2001. Despite this, housing demand remains resilient, partly due to limited supply and demographic tailwinds. The Fed’s stance remains data-dependent, balancing inflation control against growth risks.

Fiscal Policy & Government Budget

Federal fiscal policy continues to emphasize deficit reduction, limiting stimulus measures that could otherwise support housing affordability. State and local governments face budgetary pressures, constraining infrastructure investments that might alleviate supply bottlenecks.

External Shocks & Geopolitical Risks

Geopolitical tensions in Eastern Europe and trade uncertainties with China pose downside risks to economic growth and housing demand. Energy price volatility also threatens to increase living costs, indirectly affecting housing affordability.

Historically, the HPI has shown volatility around monetary policy shifts. The current rebound follows three consecutive months of flat or negative growth, reminiscent of the 2023 tightening cycle when prices dipped 0.30% MoM over three months before recovering. The October print suggests that housing demand remains robust despite higher borrowing costs.

Market lens

Immediate reaction: Following the release, the 2-year Treasury yield jumped 5 basis points, reflecting increased hawkish bets. The US dollar index gained 0.15%, while the S&P 500 declined 0.30%, signaling investor caution on growth amid persistent inflation.

Looking ahead, the US housing market faces a mix of supportive and constraining factors. The bullish scenario (30% probability) envisions continued price gains of 0.30–0.50% MoM, driven by tight supply, strong labor markets, and moderate mortgage rate stabilization. This would sustain shelter inflation and pressure the Fed to maintain or raise rates.

The base case (50% probability) anticipates modest growth of 0.10–0.30% MoM, as higher borrowing costs gradually temper demand but supply constraints persist. Inflation pressures would ease slightly, allowing the Fed to pause rate hikes by mid-2026.

The bearish scenario (20% probability) involves a sharper slowdown or mild contraction (-0.10% to -0.30% MoM), triggered by rising geopolitical risks, fiscal tightening, or a spike in mortgage rates above 7.50%. This could lead to a housing market correction and reduce shelter inflation, easing pressure on monetary policy.

Structural & Long-Run Trends

Demographic shifts, including millennial homebuying and migration to suburban and exurban areas, support long-term housing demand. However, supply-side constraints—zoning laws, labor shortages, and material costs—limit new construction, sustaining upward price pressure.

The October 2025 US House Price Index MoM reading of 0.40% signals a robust rebound in housing prices, reversing recent declines and exceeding expectations. This strength underscores persistent shelter inflation, complicating the Federal Reserve’s path toward price stability. While financial conditions remain tight, demand resilience and supply shortages continue to support prices. Policymakers must weigh these dynamics amid external risks and fiscal constraints. Market participants should monitor regional divergences and mortgage rate trends closely, as these will shape the housing market trajectory in the coming quarters.

Key Markets Likely to React to House Price Index MoM

The US House Price Index MoM release typically influences several key markets. The housing sector’s sensitivity to interest rates and inflation makes Treasury yields, the US dollar, and equity indices particularly reactive. Additionally, certain stocks and cryptocurrencies linked to real estate and financial services often track housing trends closely.

• SPY – Tracks US equities, sensitive to housing market sentiment and interest rate changes.
• USDCAD – Reflects cross-border capital flows influenced by US economic data, including housing.

Insight: US House Price Index vs. SPY Since 2020

Since 2020, the US House Price Index and SPY ETF have shown a positive correlation, particularly during periods of monetary easing and tightening. Housing price surges often coincide with equity market rallies fueled by low rates. However, during tightening cycles, divergences appear as rising mortgage rates weigh on housing but equities may remain buoyed by tech sector strength. The October 2025 HPI rebound aligns with a recent SPY pullback, highlighting market caution amid inflation concerns.
