The lag in official shelter inflation is one of the most important and least-discussed features of the current cycle. BLS measures owners’ equivalent rent using a survey of existing leases, which rotates slowly. When rents spiked in 2022 and 2023, the official measure took 12-18 months to fully reflect it. The same is true in reverse.
New-lease asking rents in major markets peaked around mid-2024 and have been flat to slightly negative since. Apartment List, CoStar, and Zillow’s new-lease indices all show year-over-year growth running negative or near zero as of early 2026. The BLS measure still reads +4.8%. These two things can both be true because the BLS is measuring the average of all existing leases, not just new ones signed in the past 90 days.
The implication: shelter’s contribution to CPI will mechanically fall over the next 12 months regardless of what happens to the economy. When it does, core CPI will drop from its current 3.1% to something closer to 2.0-2.5% without the Fed doing anything additional. Whether the remaining 0-0.5 points of stickiness requires another rate cut or just patience is the genuine policy question. The answer depends almost entirely on services ex-shelter, which tracks wage growth. Wages are growing at 3.8%. That is close enough to 2% inflation to be comfortable. The Fed will cut once more before year-end, probably September.
