Financial Contagion Network Analysis
Portugal's position in the global financial network produces a SIGMA score of 57.9/100 (ACCUMULATION regime). The financial contagion R₀ coefficient quantifies whether risk originating in Portugal would spread sub-epidemically (R₀<1.0), spread linearly (1.0-1.5), or propagate exponentially through interconnected financial systems (R₀>1.5).
The SIGMA Engine v5.0 derives this score from eight deterministic analytical layers: metabolic lifecycle entropy (β=1.003, biological age 103 months), structural fragility (Minsky phase: hedge), NLP narrative divergence (0.0%), network contagion (R₀=1.073, percolation intact), and predictive signals (CSD=30.0, Hawkes λ=0.1000).
Regime probability distribution as of 2026-06-10: stable 26.3% / accumulation 25.7% / critical 26.6% / collapse 21.5%. The Hurst exponent of 0.708 indicates strong trend persistence — risk trajectory statistically likely to deepen.
Based on Markov chain transition probability from current ACCUMULATION regime. Kairos arbitrage window: 31 days.
Methodology: SIGMA scores are deterministic (identical inputs = identical outputs).
