A case study of Brazil's January 1999 currency crisis — tracing the collapse of the Real Plan's crawling-peg regime, the ~50% depreciation of the real against the dollar, and the policy response that prevented a lost decade. The analysis applies three-generation crisis theory to explain why Brazil escaped the fate of Argentina, which defended a similar peg until catastrophic collapse in 2001–02. Presented as part of the Financial Crises and Policy Dilemmas in Emerging Markets and Latin America course at Johns Hopkins SAIS (Fall 2025).
