Causal Effect

-5pp(lower)

A surprise cut weakens the dollar and adds demand stimulus, modestly reducing the already-low probability of inflation convergence — but the effect is small because dual supply shocks dominate regardless of policy rate

Unconditional probability:21.8%(blended: P(Y|T) × 5.0% + P(Y|F) × 95.0%)

Why This Matters

Tests whether inflation convergence can complete under easing conditions. Core PCE is currently stuck above 2.5% with the regime reclassified from MODERATING to PERSISTENT. Dual supply shocks (tariffs + Iran oil) dominate the inflation driver composition. A May cut would signal the Fed prioritizes employment over inflation — potentially weakening the dollar further (compounding import inflation) and adding demand stimulus. The March SEP revised core PCE to 2.7% for 2026 and pushed convergence to 2% out to 2028. 5Y TIPS breakevens at 2.63% suggest market expectations are drifting.
