September PPI Report Impact Analysis: Inflation Trends and Fed Policy Implications

On November 25, 2025 (EST), the U.S. Labor Department released delayed September Producer Price Index (PPI) data showing wholesale prices rose by 0.3% month-over-month (MoM), in line with economists’ expectations, after a 0.1% decline in August [0]. The annual wholesale inflation rate remained at 2.7% following a revision to August data [0]. This almost three months old data will be the most recent official inflation metric available to the Fed at its December meeting (WSJ [0]). Core PPI (excluding volatile food and energy costs) eased in September, providing mixed signals on underlying inflation trends [0].

The immediate market reaction on November 25 showed:

• Sector Performance
  : Interest rate-sensitive sectors like Utilities (+3.22%) and Energy (+2.09%) led gains, while Consumer Defensive (-1.29%) underperformed [4]. This reflects investor interpretation of mixed inflation signals: headline PPI increases (driven by 3.5% MoM energy price jumps [0]) supported energy stocks, while easing core inflation boosted rate-sensitive sectors (Utilities) amid hopes for a dovish Fed stance [4].
• Index Trends
  : Prior to the data release (Nov 18-24), major indices like the S&P 500 (+1.03% on Nov24) and NASDAQ (+1.73% on Nov24) posted gains, indicating pre-existing market optimism [3].

The delayed PPI data introduces uncertainty for the Fed’s December decision:

• The Fed will rely on outdated inflation metrics, potentially leading to a more cautious policy stance [0].
• Mixed signals (headline up, core down) could split Fed officials on rate cut timing, increasing market volatility [0].

Investor sentiment tilted toward rate-sensitive and cyclical sectors, suggesting expectations of a balanced Fed response (no immediate rate hikes but delayed cuts) [4].
