Causal Effect

-3pp(lower)

A surprise cut weakens the dollar and adds demand stimulus into a supply-constrained regime, modestly reducing the already-diminished probability of inflation convergence — but both branches are now pushed lower by the April data, and the relative delta narrowed as supply-side dominance makes both branches more sticky.

Unconditional probability:15.5%(blended: P(Y|T) × 15.0% + P(Y|F) × 85.0%)

Why This Matters

Tests whether inflation convergence can complete under easing conditions. Core PCE YoY is at 2.9% with the 3mo annualized at 4.4% (worsening from 3.7% in March). The regime is PERSISTENT with intensifying momentum. Triple supply shocks (tariffs + crude + refining product inversion) dominate the inflation driver composition; retail gasoline passed through to $4.04/gal and headline CPI surged to 3.3% YoY. A May cut would signal the Fed prioritizes employment over inflation — potentially weakening the dollar further (compounding import inflation), adding demand stimulus into supply-constrained energy complex, and removing the disinflationary effect of elevated real rates.
