Rates (the Selic) in the Radar: the backdrop of the regimes
◦ Written under index methodology v1 (in effect until 15 Jul 2026). The current series is v2 — readings quoted here may differ from those shown today. See the methodology.
Concept
The Selic is Brazil's benchmark interest rate — and, in the Radar's archive, it works as the slow backdrop against which the regimes take shape. It does not change every day; when it does, it usually takes time to appear in the market thermometers.
How to read it. A high rate makes risk more expensive and rewards what yields without depending on the economy; a low rate pushes capital toward risk. But the Selic is the most lagging thermometer: the market usually turns months before the rate cycle follows.
Why it matters. Many inflections in the archive happened with the Selic still parked — the structure and appetite changed first, and the cut (or the hike) only came later, confirming what the market was already reading.
What it is not. It is not a trade trigger. "Rates are going to fall" is not a Radar forecast; what the archive records is the order in which things usually happen — market first, rate later.
