Causal Effect

+14pp(higher)

A rate cut compresses the Fed-ECB rate differential from 100bp to 75bp and signals employment-first prioritization, both bearish for the dollar and accelerating the existing depreciation trend

Unconditional probability:41.7%(blended: P(Y|T) × 5.0% + P(Y|F) × 95.0%)

Why This Matters

Tests whether a rate cut accelerates dollar weakness beyond the existing depreciation trend. The broad trade-weighted dollar stabilized at 120.6 — the 12-month decline of 7.6% persists but is no longer accelerating. Forward-looking rate differential compression continues as markets price constrained Fed easing relative to peers (ECB at 2.50%, BOJ normalizing). A cut would widen the rate differential compression, potentially reigniting depreciation. But US growth outperformance partially offsets rate differential pressure. Dollar weakness compounds tariff-driven import inflation — crossing below 115 would amplify cost-push dynamics.
