Key Takeaways

Supply Shock Focus: Major hyperinflations repeatedly followed severe economic disruptions, including Georgia’s 56% output collapse between 1991 and 1992 and Zimbabwe’s 50% output decline from 2000 to 2008.
Foreign Debt Risks: External debt and foreign currency obligations amplified currency collapses, with Yugoslavia’s fiscal deficit rising from 3% of GDP in 1990 to 28% in 1993.
