Dollarization occurs when a country uses US Dollar or other currency instead of or along with local currency. The picture of dollarization can be as follow: using dollar for bank Deposit, paying debt, buying goods and service, measuring national budget. 1 There are three types of dollarization: official, semi-official, and unofficial. Official dollarization occurs when a country use dollar as the legal currency instead of domestic currency. For example, Panama is the dominant official dollarization adopter. It has no domestic currency published at all. The second type is Semi-official dollarization. Some countries in the world use US dollar and domestic currency at the same time; in other word, they use bimonetary systems. This allows people to make deposit in US dollar, do some transaction, but it only act as second role in paying wage, tax, electricity, and daily expense. Adopting this system, the central bank can place its own monetary policy. Cambodia, Lao, and Haiti are the examples of semi-dollarized countries. Third, in unofficial dollarization, some countries’ majority wealth is hold in foreign currency and people can use US dollar substituting domestic currency either legally or illegally. In short, when a country uses other currency beside it own to substitute the three functions of the monetary, it is theoretically that the country has been dollarized formally, semi-formally or informally.
