What if Brazil hikes its Selic rate to 16% to defend the real?
A BCB push of Selic toward 16% to defend the real ripples through EM local-currency debt: the read is higher EM reals, a firmer dollar and pressure on carry and high-beta risk as the highest-yielder ratchets rates. Rhymes with Brazil's 2015-16 and 2021-22 tightening cycles that lifted global EM-rate betas. Brazil exports soy/iron ore to China and funds via local debt; a Selic defense protects FX at growth's expense. Forward: heavy domestic debt service makes the fiscal-monetary loop the real risk, not FX alone.
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. Brazil's central bank pushes Selic sharply higher to defend the real, sending global EM-rates and local-currency debt reeling. The trigger decomposes into signed root‑shocks — FX carry appetite ▼ · 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 cascade's SHORT on HOOD: its +9% leans on Wagner (+34%) and Egypt (+21%) — crypto/retail-flow spikes unrelated to a Selic hike; HOOD's macro channel is swamped by crypto-beta.
Historical precedent — what analogous events actually did
Across 33 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
BCB hiked Selic toward 15% already; pushing to 16% to defend real is a plausible extension. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
