US Core PPI YoY: September 2025 Release and Macro Implications
The September 2025 Core Producer Price Index (PPI) YoY for the US came in at 2.80%, below the 3.50% consensus and down from August’s 3.70%. This marks a notable deceleration from earlier 2025 peaks near 3.60%. Key drivers include easing shelter and energy input costs. The print signals moderating inflation pressures, supporting a cautious Federal Reserve stance amid mixed macro signals. Financial markets reacted with a mild rally in short-dated Treasuries and a slight USD depreciation. Risks remain from persistent supply chain disruptions and geopolitical tensions, but structural disinflation trends continue to gain traction.

The US Core PPI YoY for September 2025 registered 2.80%, marking a significant slowdown from August’s 3.70% and well below the 3.50% consensus estimate. This figure reflects a cooling in wholesale inflation pressures after a volatile first half of the year. The data covers the entire US economy, excluding volatile food and energy components, providing a clearer view of underlying inflation trends over the past 12 months.
Drivers this month
- Shelter-related input costs contributed 0.15 percentage points, down from 0.30 in August.
- Used vehicles and transportation equipment prices declined, subtracting -0.10 percentage points.
- Energy-related intermediate goods saw a mild easing, reducing upward pressure.
Policy pulse
The 2.80% reading sits below the Federal Reserve’s 2% inflation target but remains elevated for core wholesale prices. This suggests the Fed may maintain a cautious approach, balancing inflation containment with growth concerns. The moderation supports a potential pause or slower pace in rate hikes, given the recent tightening cycle.
Market lens
Immediate reaction: The 2-year Treasury yield fell 8 basis points within the first hour, while the USD index weakened by 0.30%. Equity markets showed mild gains, reflecting relief at easing inflation pressures.
Core PPI is a vital inflation gauge, complementing the Consumer Price Index (CPI) and Personal Consumption Expenditures (PCE) price index. Its YoY trajectory offers insight into cost pressures faced by producers, which often precede consumer inflation.
Historical comparisons
- September’s 2.80% is the lowest since July 2024’s 2.60%, signaling a sustained downtrend from the 3.60% peak in February 2025.
- The 12-month average Core PPI YoY since January 2024 stands at approximately 3.20%, underscoring the recent moderation.
- Compared to the post-pandemic surge in 2021-22, when Core PPI exceeded 8%, the current level reflects a significant normalization.
Monetary policy & financial conditions
The Federal Reserve’s recent rate hikes have tightened financial conditions, contributing to the easing of inflationary pressures. The Core PPI’s deceleration aligns with the Fed’s goal of bringing inflation closer to 2%. However, the persistence above target suggests vigilance remains necessary.
Fiscal policy & government budget
Government spending remains moderately expansionary, with infrastructure and social programs supporting demand. However, fiscal tightening in other areas has helped temper inflation. The budget deficit trajectory is stable, limiting additional inflationary stimulus.
Drivers this month
- Shelter costs slowed, reflecting softer rent growth and construction input prices.
- Used vehicle prices declined, influenced by improved supply chains and reduced demand.
- Energy intermediate goods prices stabilized after volatile swings earlier in the year.
Policy pulse
The downward trend in Core PPI supports the Federal Reserve’s recent signaling of a potential pause in rate hikes. Inflation expectations have moderated, reducing pressure on monetary tightening.
Market lens
Immediate reaction: The USD weakened against major currencies, with EUR/USD rising 0.25% post-release. Short-term Treasury yields declined, reflecting market optimism about inflation control.
This chart confirms a clear easing in wholesale inflation pressures, reversing the mid-year spike. The trend suggests inflation is moving closer to the Fed’s target, reducing the likelihood of aggressive monetary tightening in the near term.
Looking ahead, Core PPI’s trajectory will be shaped by several factors, including supply chain normalization, labor market dynamics, and geopolitical developments. The Federal Reserve’s policy decisions will also hinge on incoming inflation data and economic growth signals.
Bullish scenario (30% probability)
- Core PPI falls below 2.50% by year-end, driven by sustained supply improvements and subdued wage growth.
- Fed pauses rate hikes, possibly cutting rates in H1 2026, boosting equities and credit markets.
- USD weakens moderately, supporting export growth and corporate earnings.
Base scenario (50% probability)
- Core PPI stabilizes around 2.70-3.00%, reflecting balanced inflation pressures.
- Fed maintains current rates with a cautious stance, monitoring inflation and growth data.
- Financial markets remain volatile but broadly stable, with moderate USD fluctuations.
Bearish scenario (20% probability)
- Core PPI rebounds above 3.50% due to renewed supply shocks or wage pressures.
- Fed resumes rate hikes, risking tighter financial conditions and slower growth.
- USD strengthens sharply, pressuring multinational earnings and global trade.
The September 2025 Core PPI YoY reading of 2.80% signals a meaningful easing in wholesale inflation pressures. This aligns with broader macroeconomic trends of moderating price growth and cautious monetary policy. While risks from external shocks and geopolitical tensions persist, structural disinflationary forces appear to be gaining ground. Market reactions underscore investor relief but also caution, reflecting uncertainty about the Fed’s next moves and global economic conditions.
Continued monitoring of Core PPI alongside CPI, PCE, and labor market data will be essential to gauge inflation’s trajectory and inform policy decisions. The balance of risks suggests a nuanced outlook, with inflation likely to remain above target but trending downward.
