- A true readingAug 2024

moves 26% from 2024-07-01, 26 deviations outside this series' own normal; check the source
+26% in 2024-08: a single-month cost-pass-through move; not tied to a specific documented event the way the 2022/2023 crisis moves are, but of a piece with this index's generally high post-crisis volatility. Lower confidence than the other entries in this group; left as true_reading rather than open because nothing about the value looks like a parsing or unit error (no reversion, plausible neighbouring months).
