What if the Fed makes an emergency 50bp rate cut?
Emergency 50bp inter-meeting cut: front-end and real yields drop, the 2y rallies ~8bp, and long-duration tech (Nasdaq) and crypto lead on the lower discount rate. The rhyme is the Mar-2020 emergency cuts and the SVB-week repricing (Mar-2023) — front end collapsed and growth/tech outperformed. Skeptic's note: an inter-meeting cut signals the Fed sees stress, so the knee-jerk risk rally can reverse if the why is a credit event rather than a soft-landing insurance cut — buy duration first, fade the equity pop until the catalyst is known.
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 risk-on shock. The Fed cuts 50bps in an emergency inter-meeting move amid stress. The trigger decomposes into signed root‑shocks — Fed policy path ▼ — 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
Why we may diverge from history
Trust the cascade long on HOOD/COIN: their short history is thin (n=5) and contaminated by 2021 Turkish-lira and 2023 SVB crisis windows — an emergency Fed cut bids crypto-beta.
Historical precedent — what analogous events actually did
Across 32 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
Emergency inter-meeting 50bp cut needs acute stress; rare absent crisis trigger; 6mo. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
