What if a prime broker fails on rehypothecated client assets?
A mid-tier prime broker failing with client assets trapped in rehypothecation chains freezes hedge-fund redemptions — a counterparty-plumbing tail where high-beta (SOL/Nasdaq), HY and financials sell hard on collateral uncertainty and VIX spikes. Direct rhyme is Lehman's London PB, where rehypothecated client assets were frozen for years. Rehypothecation links every client through opaque collateral chains; one failure jams many funds. Forward angle: post-2008 segmentation reduced but did not remove this — the lesson is counterparty diversification, and the reflex is a broad degross while custody is sorted.
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 mid-tier prime broker's collapse traps client assets rehypothecated through opaque collateral chains, freezing hedge-fund redemptions. 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% lift sits entirely in the March-2023 SVB-rebound regime and reflects INTC's foundry idiosyncrasy — a prime-broker rehypothecation freeze locks redemptions and forces selling, not buying.

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.
