Fed’s Preferred Inflation Gauge Supports Rate Cuts, Boosting Market Sentiment

The event centers on the release of the Federal Reserve’s preferred inflation measure—core personal consumption expenditures (PCE) price index—showing a 0.2% month-over-month increase in September, matching August’s pace [1]. The report was delayed five weeks due to a government shutdown, providing retrospective but critical data on inflation trends. The moderate inflation rise aligns with the Fed’s target, indicating reduced inflationary pressures and giving the central bank leeway to consider interest rate cuts.

Market reaction to this signal was positive: the SPY ETF (tracking the S&P 500) rose 0.30% on December 5 and gained 0.82% over the preceding five days [0]. This reflects investor optimism that rate cuts would lower borrowing costs, stimulate economic activity, and support corporate valuations. The delay in the report does not appear to have dampened the market’s positive response, as the underlying inflation trend remains favorable for accommodative monetary policy.

1. Inflation threshold alignment
   : The 0.2% month-over-month core PCE increase is a critical marker for the Fed, as it indicates inflation is moving toward the central bank’s 2% annual target, justifying discussions of rate cuts.
2. Policy signal impact
   : The market’s immediate positive reaction to the inflation report highlights how sensitive investor sentiment is to Fed policy signals. Even with the report delay, the data’s alignment with inflation targets has boosted confidence.
3. Retrospective data relevance
   : Despite the five-week delay, the September inflation data remains relevant for policy planning, as it confirms a sustained slowdown in price pressures, reducing the need for restrictive rates.

• Opportunities
  : Rate cuts could stimulate consumer spending (via lower borrowing costs), corporate investment, and stock market valuations. The favorable inflation data creates a window for the Fed to adjust policy without risking a resurgence in inflation.
• Risks
  : The delayed report means the Fed is reacting to outdated economic data; conditions could have changed since September, potentially leading to misaligned policy decisions. Additionally, if rate cuts are not implemented as expected by markets, sentiment could reverse, leading to volatility.

The core PCE inflation report (0.2% MoM in September, delayed by government shutdown) suggests reduced inflationary pressures, supporting potential Fed rate cuts. The SPY ETF responded with a 0.30% daily gain (December 5) and 0.82% 5-day gain, reflecting investor optimism. While the data creates opportunities for accommodative policy, risks remain related to delayed data and policy implementation uncertainty.
