Summary

Iceland's three major banks collectively held assets equal to 900% of GDP — the most extreme banking sector over-leverage in modern history. The collapse in 6 days was the largest banking failure relative to economy size ever recorded.

Mechanism of failure

Extreme banking leverage + wholesale funding dependence + foreign currency liabilities + tiny central bank unable to backstop = instant collapse when wholesale markets froze.

What the early warning missed — and what SIGMA would have caught

Bank assets/GDP ratio of 900% was a 10-sigma anomaly visible to anyone looking. CDS spreads on Icelandic banks reached 800bp in June 2008 — 4 months before collapse.

Key lessons for risk assessment

1.Banking sector assets exceeding 500% of GDP is a systemic risk threshold with no historical survivor

2.When wholesale funding dependence exceeds 50% of bank liabilities, a liquidity crisis becomes existential within days

Austria

SIGMA 44.2/100 — STABLE

Austria has significant Eastern European banking exposure (Raiffeisen Bank Russia) and bank assets represent elevated % of GDP — structural similarity to Iceland 2007.
