Summary

Hungary's 2008 crisis was primarily a contagion casualty from the Lehman collapse, amplified by extreme FX mortgage exposure. 70% of Hungarian mortgages were denominated in CHF or EUR while incomes were in forints.

Mechanism of failure

FX mortgage exposure → global risk-off → forint depreciation → mortgage defaults → banking stress → sovereign financing crisis → IMF rescue.

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

The mismatch between forint income and CHF/EUR mortgage obligations was a known systemic risk. When forint depreciated 30%, mortgage-to-income ratios became unserviceable for 40% of borrowers.

Key lessons for risk assessment
1.FX mortgage lending to households creates sovereign-level systemic risk — the state inevitably absorbs household losses
2.Small open economies in CEE are highly vulnerable to global risk-off events — contagion R₀ can exceed 2
