PRISM REASONING
  • Probability estimate: 62% that BEA-reported April 2026 personal spending exceeds 0.5% month-over-month

  • +Recent months show rising personal spending, including 0.9% in March
FACTORS AGAINST
  • Only slight margin of forecast over threshold leaves downside risk
  • Short-horizon macro data can surprise versus consensus
RESOLUTION PATHS MODELED
April spending prints at or above 0.6% MoM37%
April spending between 0.51% and 0.59% MoM25%

    Source: Bureau of Economic Analysis (BEA) Resolution field: Personal income and outlays release: personal consumption expenditures / personal spending month-over-month change Frequency: monthly Known rule risks: BEA release timing is 8:30 AM ET; markets often close before the release, so consensus/nowcast quality matters; Personal spending and PCE price index are different fields — do not substitute inflation data for spending growth; MoM change is derived from seasonally adjusted monthly values; revisions to prior months can shift the implied change
