What if a corporate debt maturity wall triggers a default wave?
A maturity-wall default wave is a pure credit trade: HY bond ETFs mark down first, financials and bank credit books (JPM) follow as refinancing at higher coupons impairs the weakest issuers. Rhymes with the 2015-16 energy HY default cycle (energy spreads ~2000bp) rather than a broad crash. Forward angle: more debt now sits in private credit and direct-lending vehicles that mark slowly, so the public-HY read may understate true stress until the lagged private marks catch up.
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 1–3 years 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 corporate-debt maturity wall meets high rates, triggering a default wave. The trigger decomposes into signed root‑shocks — Credit spreads ▲ — 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 BTC: its +7% realized is the 2020-COVID liquidity-rebound regime on only 7 analogues; a corporate maturity-wall default wave is a slow credit grind with no fast Fed-reflation snapback.
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
Maturity wall real but rates easing into 2026; refinancing eases the default-wave risk. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
