What if the ECB cuts rates ahead of the Fed?
Rate-differential dollar bid: the ECB front-running the Fed widens the EUR-USD gap, so EUR/USD and GBP fall, the dollar firms, and EM FX (TRY, INR) and gold soften under DXY strength. The rhyme is 2014-15 ECB QE/divergence, when EUR/USD slid toward parity on the policy gap. Transmission: a stronger dollar tightens global financial conditions and pressures import-fragile EM; forward angle — much of the divergence may be pre-positioned, so the cleanest expression is short EUR/USD and long USD vs high-beta EM, with gold as the relief valve if the move overshoots.
how we built this number — every step
The class rate is measured from our dated, sourced event library (decade-normalized Poisson — the full table is public at base_rates.json). The variant’s share within its class is the analyst’s editorial call, published so you can audit it. A wider range means thinner precedent. Full recipe: methodology · scored at Reality Check.
The butterfly cascade
How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.
Resolution timeline — how this probability is moving
Our model's odds (gold) over time vs the crowd's (Polymarket, blue), from the past toward the 0–6 months horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. The gold path is an illustrative reconstruction anchored to today's estimate — real dated events, not a live re-estimate history.
What it would mean
If this plays out, it is a mixed shock. The ECB front-runs the Fed with cuts, widening EUR-USD rate differentials. The trigger decomposes into signed root‑shocks — US dollar (DXY) ▲ — which propagate through our causal graph to the markets below.
If it happens — the markets it would move
Biggest moves first. Projected moves are cascade-model priors; hist A–B% = what comparable past events actually did (measured abnormal returns), and model prior · unmeasured marks markets with no analogue backing yet. Tap any market for its price history.

Probable recommendation
Historical precedent — what analogous events actually did
Across 13 analogous events (overlap‑weighted), as abnormal returns — market beta stripped, so it's the event's own effect, not the market backdrop. Shown at 20 days (persistent) and 5 days (immediate); ↺ fades = the two horizons disagree. Confidence = consistency × sample × significance.

Why this probability
ECB already easing ahead of Fed; widening differentials largely in train; near-term likely. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
