Stress is just how far today's value sits between “norm” (0) and “crisis” (100) — a fixed calibrated scale, not a verdict. It measures pressure, not a prediction of collapse.
This is a year-on-year rate of change, not the absolute level — a level can stay high while its change reads as high stress.
Non-ferrous metals output currently reads -3 % YoY, mapping to a stress of 33/100 — modest pressure.
Across the tracked period the stress has held roughly flat (+0.0 pts).
The value is sourced via official statistics; confidence — medium. How it is derived: Rosstat; held up by aluminium/nickel exported around sanctions.
History is accumulating since launch — a chart appears once enough daily readings pile up.
| Period | % YoY (Nornickel average of Cu -2%, Ni -5%) | Stress |
|---|---|---|
| 2023 | -3.5 | 36 |
| 2025 | 1.7 | — |
| 2026-Q1 | -10 | — |
Proxy series (not the exact index). Longest defensible public series behind this metric — annual, open sources. Reconstructed context, not the live value; no interpolation. Sources: Nornickel 2023: copper -2%, nickel -5% (largest producer proxy) · Rosstat — 'metal ores mining' +1.7% in Jan–Dec 2025 (broader than non-ferrous metals)
