The September 2026 CPI report came in hotter than expected, with Realtor.com Research reporting that headline inflation hit 3.7% and core inflation ticked back up to 2.6%. The article was published on October 14, 2026, and framed the print as a tough one for consumers, the Federal Reserve, and the housing market.
