The extreme

Nothing changed in the rock or the grain. The currency changed. The premium that exporters carried against the market evaporated toward zero — not because iron ore or soybeans were worth less, but because the real, at its strongest in months, shrank the value in reais of everything sold in dollars. It was currency arithmetic dressed up as flow. And while the surface cooled, the deepest gauge in the house did the opposite of everything else: it pinned the ceiling. In numbers: with the dollar at R$ 4.97, the exporters' premium against the market fell to nearly zero; the banks' premium, stretched to an extreme the archive rarely records, gave back more than half of the excess; the intermarket grid loosened from 72.48 to 52.34, from strong risk-on to neutral; and the Perene Risk Index leapt from 51.7 to 100.0, the absolute top of the scale. Ânima, the surface mood, opened and closed stuck at 51.7. Selic at 11.75% a year.

What happened next

Maximum appetite didn't last. Three months later, in June 2022, the same axis that had pinned 100.0 went to zero: domestic risk swung to full risk-off and Ânima collapsed from 59.8 to 8.4, with every shelter growing expensive at the same time — real estate funds jumped from near the average to a premium well above it. In September 2022 came a partial reprieve: commodities returned from exile toward the average and the banks' premium let go by half. In March 2023 the board relapsed into defense — the cyclical/non-cyclical ratio plunged and Ânima sank to 20.6.

What did not happen

The ceiling was not a green light. The Perene Risk at 100.0 did not announce continuity — three months later the same gauge was on the floor. The bank premium withered without collapsing: it stayed above the average, with no crash. And the commodity tension abroad did not turn into commodity leadership here at home: the real swallowed the premium before it could show up on the local board.

The honest verdict

The engine read maximum structural appetite at a point that, in retrospect, was a top — pinning the ceiling was the last calm before the June collapse. But honesty asks for the rest: at the time, the reading was genuinely ambiguous, with three rulers disagreeing — Perene at 100.0, Ânima stuck at 51.7, intermarket back to neutral. The comparable configuration that matured over six months returned 7.1%, well below what similar cases used to deliver, and the engine itself classified it as an insufficient reading. The ceiling was only a warning in hindsight.
