CPI vs. PCE: What These Inflation Numbers Mean for Your Mortgage Rate

CPI vs. PCE: What These Inflation Numbers Mean for Your Mortgage Rate

  • 10/27/25

If you've turned on the news lately, you’ve probably been hit with an alphabet soup of economic terms: CPI, FOMC, and PCE. It’s easy to tune it all out, but these reports directly impact your wallet, the cost of living here in Southwest Colorado, and most importantly, the direction of mortgage rates.

As your local real estate advisor, I'm cutting through the noise to explain what these numbers mean for you.

The CPI Report: A "Better Than Expected" Surprise

Last week, we got the latest Consumer Price Index (CPI) report for September. Think of the CPI as the "people's inflation gauge." It measures the average change in prices we, as consumers, pay for a basket of goods and services—everything from groceries and gasoline to clothing and, most importantly, housing. 🏠

Here are the key takeaways from the report:

  • Inflation rose 0.3% in September, a slowdown from the 0.4% increase in August.
  • Year-over-year inflation is now at 3.0%.

While any price increase can feel frustrating, the big story here is that these numbers were better than economists expected. The market, a great indicator of expert sentiment, reacted very positively by rallying after the report was released. This suggests that despite some headlines, the overall inflation picture is improving.

A critical point to understand is that the largest component of the CPI is shelter, or housing costs. The problem? The government’s data for this is widely known to be two years out of date. For the first time in years, this latest CPI report was driven more by gas and food prices than by shelter. This is great news. As the CPI’s lagging housing data finally catches up to today's more stable prices, it will help pull the overall inflation number down even further.

The PCE Report: The Inflation Gauge the Fed Actually Watches

While the CPI gets the headlines, the Federal Reserve actually pays closer attention to a different report: the Personal Consumption Expenditures (PCE) price index. This is the one that truly influences their interest rate decisions.

Think of the PCE as the "Fed's inflation gauge." It’s a broader measure that cleverly accounts for how people change their spending habits. For example, if the price of steak skyrockets, the PCE recognizes that many people will substitute and buy more chicken instead. 🍗

The PCE report for September is due out this week. Following the positive CPI news, economists and the Federal Reserve will be watching this report closely, looking for it to confirm the cooling trend.

The Bottom Line for Southwest Colorado (Yes, It's Good News)

This is the best news the housing market has received in a long time. Here’s why:

It all boils down to mortgage rates. The Federal Reserve is meeting this week. Because the CPI report was better than feared, the market believes a Fed interest rate cut is almost certain.


A positive PCE report would give the Fed the final "green light" it needs to act. A Fed rate cut is the most powerful signal we can get that the cost of borrowing is heading down. This directly influences mortgage rates, and lower rates are the key to improving housing affordability and bringing more stability to our Southwest Colorado market.

While we all feel the pinch of higher prices, the data shows we are moving in the right direction. Cooling inflation gives the Fed the confidence to act.

As always, I'm watching these trends every day. If you have questions about how this economic news impacts your personal real estate goals, please don't hesitate to reach out.
