Rent inflation: level shift

The claim

Rent CPI, % y/y: level shift detected around Feb 2025

A two-segment mean-shift scan over the last 40 months places the largest level shift in rent cpi, % y/y around Feb 2025: mean 7.49 before vs 4.44 after (shift = 3.1× pooled variability). The detector locates the shift; it does not attribute a cause.

Method

Deterministic two-segment mean-shift scan; break where |Δmean|/pooled sd ≥ 1.5 with ≥8 periods per segment.
