Deteriorating economic performance in 1997–98 culminated in a severe financial crisis in 1999. The crisis was precipitated by a number of external shocks, including the El Niño weather phenomenon in 1997, a sharp drop in global oil prices in 1997–98, and international emerging market instability in 1997–98. These factors highlighted the Government of Ecuador's unsustainable economic policy mix of large fiscal deficits and expansionary money policy and resulted in a 7.3% contraction of GDP, annual year-on-year inflation of 52.2%, and a 65% devaluation of the national currency in 1999.
