The alarm that came from the price of money, not from fear — Jan 2011

Episode

The extreme

Two of the house's instruments were watching the same market and disagreed about what time it was. The stock market kept its confidence, domestic appetite on its feet — and yet one of the thermometers collapsed on its own all the way to the floor of the scale, without the mood having turned. The alarm did not come from fear. It came from the price of money: inflation was running ahead of the nominal rate, and the real rate measured forward compressed to a point the series has never treated as normal. In numbers: the Perene Risk Index fell from 63.7 to 2.8, marking risk_off, while the Brazilian regime closed firmly at 71.5; the ex-ante real rate registered a z of −6.28 — a critical reading —, with monthly IPCA of 0.83% against a Selic of 11.25% a year that had not yet responded.

What happened next

The mismatch did not resolve at once — it swung. In April, the appetite thermometer retraced its path and marked risk_on with room to spare (86.4), while the Central Bank raised the Selic to 12.0% a year. The calm did not last: in July the same index slumped again, from 73.4 to 14.8, the sharpest drop the series had recorded. Only in January 2012, with the Selic already cut to 10.5%, did the two clocks strike together — the Perene Risk Index reached the ceiling, at 100.0. From discord to reconciliation, it took a full year.

What did not happen

The mood did not collapse along with the alarm. The domestic regime never left the ground of assumed risk — 71.5 in January, 67.4 in April, 65.3 in July. Anyone reading the floor of a thermometer as a turn in sentiment would have gotten the diagnosis wrong: the distortion lived in the rate structure, not in the appetite for stocks. And April's recovery did not close the matter either — July undid it again.

The honest verdict

The alarm was right to point to a real distortion: the price of money out of sync with current prices. But the engine itself admitted the limit — when January's verdict matured, months later, the deterministic calculation marked it as not assessable, with a single analogous episode found, below the minimum of five. With no sample, it recorded honest silence rather than a fabricated forecast.
