What if Hungary's spending splurge breaches EU deficit rules and sinks the forint?
A 6.2% deficit breach forces MNB to hold instead of cut: short HUF (the highest-carry CE3 funder) as the rate-cut path is repriced hawkish and the EDP premium widens. Direct analogue is Hungary 2022, when the forint hit ~430/EUR and MNB ran an 18% effective rate to defend it. Hungary funds itself in EU markets and trades on German demand; the live risk is that frozen EU funds compound the fiscal hole. AUD/EM-FX cascade lines are peripheral — this is a forint carry-unwind story.
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 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. New government's spending pushes 2026 deficit to 6.2%, breaching the EDP path; forint slides, forcing MNB to abandon rate cuts. The trigger decomposes into signed root‑shocks — FX carry appetite ▼ · 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
Why we may diverge from history
Trust the measured history LONG XAU: eleven clean, on-channel crisis analogues hit 93% with gold up — a forint slide and MNB pause is exactly the EM-stress flight-to-gold bid the cascade's SHORT under-weights.
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
Hungarian fiscal slippage and forint pressure are recurrent; deficit breach plausible but 6.2% + MNB U-turn specific. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
