On October 14, 2026, the Bureau of Labor Statistics reported that the Consumer Price Index rose 3.7 percent in the 12 months through September, while the index excluding food and energy, the core rate, rose 2.6 percent after 2.4 percent through August. Shelter, the largest single block in both measures, rose 3.2 percent over the same 12 months. For anyone reading the two rates side by side, that one component pushes them in opposite directions: it lifts core from 2.0 percent to 2.6 and holds the all-items rate at 3.7 instead of 4.0, so the claim that housing is pushing inflation up is true of one number and false of the other. The figures come from the BLS Consumer Price Index news release for September 2026 and its first three tables. This post follows the shelter line through them: what the index counts as shelter, why September's monthly shelter increase of 0.4 percent is not a rent number, and how much of each 12-month rate shelter accounts for once the rounding comes off.

Across the last five quarters, the dollar share as first published ran 57.79, then 56.32, then 56.92, then 56.77, then 57.13. Read as a sequence of decisions, that is a violent story: a collapse, a partial recovery, a stall, a snap back. Read as arithmetic, most of it never happened. The IMF itself has said so, in plain language, in its own release notes. For the second quarter of 2025, when the published dollar share fell 1.47 percentage points, the Fund wrote that the share "would have decreased by only 0.12 percentage points (p.p.) if th...
