What if a ransomware attack locks up a top global custodian's assets?
Ransomware freezing a top-three global custodian blocks redemptions, collateral, and corporate actions — a tail operational shock that forces broad de-risking as trillions in safekept assets go dark. Rhymes with the 2017 NotPetya hit on Maersk and the 2023 ICBC Financial Services ransomware that disrupted US Treasury settlement for days. Forward angle: custody is concentrated in BNY/State Street/JPM — a single-point cyber failure has no quick workaround; the cleanest hedge is long vol and gold, not directional credit.
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 ransomware strike on a top-three global custodian freezes trillions in safekept assets, blocking redemptions, collateral, and corporate actions. The trigger decomposes into signed root‑shocks — Credit spreads ▲ · 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 INTC: its +4.8% is the 2023-03 SVB dovish-relief regime, irrelevant to a custodian cyber lockout, and the comparable Lehman freeze analogue prints -25%.
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
Top-three custodian ransomware lockout is severe tail; strong defenses, never occurred at scale. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
