MiCA Stablecoin Reserve Stress Simulator

Monte Carlo simulation of stablecoin reserve portfolios under MiCA Article 36 redemption stress and asset price shocks — the core regulatory stress test required of Asset-Referenced Token (ART) and E-Money Token (EMT) issuers. 1,000 paths × 90-day horizon. Complements ART-06 (static attestation pre-check) with the full stochastic dimension. All computation runs locally — no reserve data leaves your browser.

⚠ Simulation only — not supervisory stress testing. MiCA Regulation (EU) 2023/1114 Title III/IV is in force. ESMA regulatory technical standards (RTS) on reserve stress testing for ARTs are under development; Article 36 liquid-buffer thresholds used here are illustrative proxies pending final RTS. This tool is for pre-validation, scenario planning, and educational purposes. It is not a substitute for a formal supervisory stress test conducted under ESMA/NCА guidance.

Issuer & reserve configuration

Token type Determines Art. 36 liquid buffer threshold

Coverage ratio at t = 0 (%) Reserve assets ÷ outstanding liabilities. MiCA minimum = 100%

Liquid asset fraction (%) % of reserves in MiCA-eligible highly liquid assets (Art. 36)

Monte Carlo paths 200–2,000. Higher = more precise percentiles

Horizon (days) 30–180. MiCA standard = 90-day stress window

Redemption stress scenario

Bank Run

Exponential redemption surge peaking at day 20. Cumulative drain ~40% of liabilities. Most severe short-horizon scenario.

Gradual Drain

Linear redemption increase 0.3%→1.0% per day over the horizon. Cumulative drain ~50% over 90 days. Tests slow-bleed resilience.

Flash Crash

15% redemption spike on day 3, followed by 0.5%/day recovery drain. Tests liquidity buffer adequacy under sudden demand shock.

Asset price shock severity

Mild σ = 0.8% · peak drop 8%

Moderate σ = 1.5% · peak drop 20%

Severe σ = 2.5% · peak drop 35%

Fire-sale contagion parameters

Fire-sale haircut 20%

Art. 36 buffer trigger (%) 30%

Fire-sale haircut applied to illiquid asset disposals when liquid buffer falls below trigger. Art. 36 threshold: illustrative 30% for ART, 20% for EMT — final ESMA RTS pending. [¹ MiCA Art. 36(2)]
