What if the ECB triggers its anti-fragmentation bond-buying tool?
Activating TPI to cap a periphery blowout is the tell that BTP-Bund stress is already acute: the trade is short EU financials and HY credit as fragmentation risk leaks, with peripheral spreads the cleanest instrument. Rhymes with the July 2022 TPI unveiling and the 2012 OMT 'whatever it takes' — both compressed spreads but exposed the tool's conditionality. Forward: with QT ongoing and PEPP reinvestments gone, the ECB's backstop is thinner than 2012.
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 0–6 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. 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. The ECB activates Transmission Protection Instrument bond-buying to cap a peripheral spread blowout, exposing the limits of its anti-fragmentation tool. The trigger decomposes into signed root‑shocks — Credit spreads ▲ · Fed policy path ▼ — 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 25 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
TPI activation needs disorderly peripheral blowout; spreads contained mid-2026, modest tail. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
