The creation of stable macroeconomic environments was the foundation upon which the Asian miracle was built. Each of the Four Asian Tiger states managed, to various degrees of success, three variables in: budget deficits, external debt and exchange rates. Each Tiger nation's budget deficits were kept within the limits of their financial limits, as to not destabilize the macro-economy. South Korea in particular had deficits lower than the OECD average in the 1980s. External debt was non-existent for Hong Kong, Singapore and Taiwan, as they did not borrow from abroad. Although South Korea was the exception to this – its debt to GNP ratio was quite high during the period 1980–1985, it was sustained by the country's high level of exports. Exchange rates in the Four Asian Tiger nations had been changed from long-term fixed rate regimes to fixed-but-adjustable rate regimes with the occasional steep devaluation of managed floating rate regimes. This active exchange rate management allowed the Four Tiger economies to avoid exchange rate appreciation and maintain a stable real exchange rate.
