What it’s telling us · as of 2026-09-01

Headline CPI prints 3.72% year-over-year, up from 324.245 a year ago to 336.298 now—a steady creep that's outpacing the Fed's 2% target and eating into the real returns on your fixed-rate mortgages. The trajectory over the past six months shows persistent upward pressure, with August's print the highest in the recent run, suggesting the disinflationary trend from 2023-24 has stalled. For investors sitting on sub-4% mortgages locked in during the 2020-21 window, this is the erosion cost you factored in; for anyone refi'd or underwater on a new purchase, it's a reminder that rate cuts don't matter if inflation stays above 3.5% and nominal yields stay compressed. Watch whether September prints stick near this level or roll over—if headline stays above 3.5% through year-end, the Fed's next move is likely a pause, not a cut.
