Explanation

What changed and how unusual it is

Derived

What changed. The latest current observation for US consumer price index, all items, United States, is 336.3 index 1982-1984=100 for 2026-09-01 (obs 415538). The previous period, 2026-08-01, recorded 334.13 index 1982-1984=100 (obs 409148). The change is +2.17 index 1982-1984=100, or +0.65%. The metric is classified as contextual, so the change carries no better or worse reading on its own.

How unusual. Against the 954 earlier monthly changes since 1947-01-01, the median change is +0.24 index 1982-1984=100 and the robust spread (scaled median absolute deviation) is 0.3106, giving a robust z-score of 6.2. The absolute change sits at the 99th percentile of earlier absolute changes; the value itself sits at the 100th percentile of earlier values. The last larger move was +2.83 index 1982-1984=100 in 2026-03-01 (obs 167368, obs 167367), 6 periods ago. The value is a new high for the series, above 334.13 index 1982-1984=100 in 2026-08-01 (obs 409148).

Acceleration. The change in the change (second difference) is +0.849 index 1982-1984=100, a robust z of 5.7 against earlier second differences. The slope over the last 3 periods is +1.74 index 1982-1984=100 per period against +1.09 over the last 10, a divergence of 2.09 change-scale units.

AI explanation

Modeled interpretation

Modeled
Explanation generated from Humanity Vector's structured data and evidence graph. Calculations and source provenance are independently stored and viewable. Model grok-4.3, prompt version 1.0.0, run 8e3e42eb-da09-4b86-9463-01e96e1802e3. Every number in this text was checked against stored evidence before display.

Explanation

The data are consistent with an unusually large monthly move as the observed value reached 336.298 index 1982-1984=100 on 2026-09-01 [observation:415538] from the prior observed value of 334.131 on 2026-08-01 [observation:409148]. The model estimates a surprise robust z of 6.204 and an acceleration slope divergence of 2.0907 while periods since larger move equal 6. Derived series show labor hours per CPI basket indexed to 2007 at 0.8969 on 2026-09-01 [observation:420644] versus 0.8923 on 2026-08-01 [observation:411229].

Alternative explanation (skeptic pass)

The data are consistent with normal variation around the recent trend given the observed values in earlier months such as 330.293 in March 2026 [observation:167368].

Why now

The combination of surprise robust z 6.204, acceleration score 0.8788 and rarity score 0.3175 flagged the September 2026 observation for review.

What to watch

Subsequent observed values of the US consumer price index all items [observation:415538] and the derived labor hours per CPI basket [observation:420644].

What points the other way

7 related metrics moved the other way as of their latest periods:

  • Consumer price inflation (IMF WEO): -0.2226 percent change (-7.54%) to 2.73 percent change in 2025-01-01 (obs 356291, obs 356290)
  • Gross capital formation as share of GDP: -0.0375 percent of GDP (-0.17%) to 21.53 percent of GDP in 2024-01-01 (obs 60180, obs 60181)

  • Real GDP growth (IMF WEO): -0.6077 percent change (-20.59%) to 2.34 percent change in 2025-01-01 (obs 420513, obs 420512)

Limits: the score compares period-over-period changes of current rows only; earlier vintages are not compared. Related metrics were found by shared category, not by a tested mechanism, so agreement among them does not establish cause.

What to watch

Measurable indicators

  • The next US consumer price index, all items observation (2026-10-01): a change no larger than the median monthly change of +0.24 index 1982-1984=100, or a move back the other way, would mean the latest change has normalised.
  • Current account balance (IMF WEO), currently -3.81 percent of GDP in 2025 (obs 417116): a move the other way lowers the breadth component.
  • GDP per person, constant 2015 US$, currently 67,945.61 constant 2015 US$ per person in 2025 (obs 49154): a move the other way lowers the breadth component.
  • General government gross debt (IMF WEO), currently 124.38 percent of GDP in 2025 (obs 418491): a move the other way lowers the breadth component.
  • Revisions: a revised 2026-09-01 value would arrive as a new observation row (the current row is observation 415538) and trigger a rescore.
  • Expiry: this insight expires 30 days after discovery unless a newer period supersedes it, and earlier if the relevance score falls below the threshold.
