when did el salvador start using the dollar
Salvadoran colón The colón was the currency of El Salvador between 1892 and 2001, until it was replaced by the U.S. Dollar. It was subdivided into 100 centavos and its ISO 4217 code was SVC. The plural is colones in Spanish and was named after Christopher Columbus, known as Cristóbal Colón in Spanish.
Convertibility plan The Argentine Currency Board pegged the Argentine peso to the U.S. dollar between 1991 and 2002 in an attempt to eliminate hyperinflation and stimulate economic growth. While it initially met with considerable success, the board's actions ultimately failed. In contrast to what most people think, this peg actually did not exist, except only in the first years of the plan. From then on, the government never needed to use the foreign exchange reserves of the country in the maintenance of the peg, except when the recession and the massive bank withdrawals started in 2000.
