What if Tokyo openly directs the Bank of Japan to absorb new debt?
Tokyo directing the BOJ to absorb JGB issuance breaks the fiscal-monetary firewall — the trade is short JPY and long gold/BTC, with the global spillover being higher long-end yields elsewhere as the world's largest creditor monetizes. Rhymes with Kuroda's 2013 'bazooka' and YCC, which drove USD/JPY from 80 toward 150 over the cycle. Japan is the marginal global bond buyer; the forward twist is that overt monetization (vs. stealth YCC) could trigger the long-feared JGB/yen disorderly unwind and a carry-trade reversal akin to August 2024 but larger.
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 mixed shock. Tokyo openly directs the BOJ to absorb new JGB issuance, breaking the monetary-fiscal firewall. The trigger decomposes into signed root‑shocks — Dollar/reserve confidence ▼ · Fed policy path ▼ · Inflation expectations ▲ — 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's LONG on SOL/COIN: thin 5-sample history anchored on the 2021 Turkish-lira crash, an unrelated EM crisis — BOJ monetizing JGBs debases yen and bids crypto, inverting that stale base rate.
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
Open BOJ monetization order breaks firewall; Japan normalizing, not directing, mid-2026. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
