the freshest inflation print
Confidence
ROBUST : a primary official series, mechanically reported.
Reliability (DRS)
DRS 95: Computed: 100 × (CPIAUCSL(t) / CPIAUCSL(t−1m) − 1), the month-over-month change, the freshest inflation signal and the input to base-effects arithmetic: when monthly prints persistently exceed ~0.2%, the year-over-year rate rises even if the underlying trend is unchanged. This tile makes base effects visible rather than leaving them implicit in the YoY headline (C2). Noisier than YoY: read with the 3-month trend, not a single print; MoM × 12 approximates the annualized rate markets and commentary quote. BLS-produced; subject to the integrity-events DRS factor.
