Historical Crisis Analogue Analysis
Greece's current SIGMA profile of 65.0/100 (ACCUMULATION regime) is pattern-matched against a database of historical financial crises. The ML similarity engine compares current Minsky phase, leverage ratios, network topology, and NLP divergence against crisis fingerprints from 1997 (Asia), 1998 (EM), 2001 (Argentina), 2008 (GFC), 2010-12 (Eurozone), and 2022 (energy shock).
The SIGMA Engine v5.0 derives this score from eight deterministic analytical layers: metabolic lifecycle entropy (β=0.700, biological age 282 months), structural fragility (Minsky phase: ponzi), NLP narrative divergence (0.0%), network contagion (R₀=1.311, percolation intact), and predictive signals (CSD=50.0, Hawkes λ=0.1000).
Regime probability distribution as of 2026-10-13: stable 26.8% / accumulation 25.0% / critical 26.5% / collapse 21.7%. The Hurst exponent of 0.646 indicates strong trend persistence — risk trajectory statistically likely to deepen.
