What if Japan, Korea or China hits a demographic tipping point?
A demographic-collapse milestone is a slow secular shock, so the modeled move is muted (S&P -0.2%) with a small breakeven bump from labor scarcity and a soft growth read — the real expression is structurally lower terminal rates and JGB/pension dynamics. Rhymes with Japan's post-1990 aging path: chronically weak growth, low yields and pension/housing strain. Transmission: aging Japan/Korea/China are large global creditors, so a tipping point pressures their savings-glut export of capital — over time a force on global term premia, not a single-day equity event.
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.
The butterfly cascade
How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.
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 3–10 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 demographic-collapse milestone (Japan/Korea/China) hits growth, pensions and housing. The trigger decomposes into signed root‑shocks — Labor shortage ▲ · Growth surprise ▼ — 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
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
Demographic decline already biting in Japan/Korea/China; a salient milestone over decade is likely. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
