What if LDI doom loop returns as gilt collateral calls cascade?
A gilt back-up triggers margin calls on leveraged liability-driven-investment funds, forcing them to dump gilts into a falling market — a self-reinforcing collateral spiral that demands BoE intervention.
Every number ships with its receipt — the odds, the range, the precedents, and a public grade at Reality Check. The statistical machinery that produces it is proprietary.
The butterfly cascade

Resolution timeline — how this probability is moving
Our model's odds (electric blue) over time vs the market's (Polymarket, amber), from the past toward the 6–18 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. Loading the probability audit trail…
What it would mean
If this plays out, it is a risk-off shock. A gilt back-up triggers margin calls on leveraged liability-driven-investment funds, forcing them to dump gilts into a falling market — a self-reinforcing collateral spiral that demands BoE intervention. The trigger decomposes into signed root‑shocks — Volatility (VIX) ▲ · Credit spreads ▲ · Real yields ▲ · Risk appetite ▼ · Risk-parity deleveraging ▲ — which propagate through our causal graph to the markets below.
