What if a central securities depository outage halts settlement region-wide?
A multi-day CSD outage halts regional settlement and blocks collateral substitution at clearinghouses — a tail plumbing freeze that forces vol-target deleveraging as positions can't be moved or financed. Rhymes with the 2020 Euroclear/CREST outages and ASX's CHESS failures, which stranded trades but were operationally contained. Trade long vol; the risk-parity-delever channel is the right read — forced selling comes from inability to manage risk, not a fundamental credit shock.
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.

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 Tail risk 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-off shock. A multi-day CSD outage halts securities settlement region-wide, stranding trades and preventing collateral substitution at clearinghouses. The trigger decomposes into signed root‑shocks — Volatility (VIX) ▲ · Financial conditions ▲ · Risk appetite ▼ — 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 short on MSTR; the +6% is BTC-bull regime contamination from the 2023 SVB windows — a CSD settlement outage has zero bearing on that dominant crypto driver.
Historical precedent — what analogous events actually did
Across 40 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
Multi-day region-wide CSD outage rare; resilient infrastructure, classic low-frequency tail. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
