Currency board

For people who check facts
A currency board is a system by which a currency is convertible at a fixed exchange rate with another currency.

This can mean that the currency is fully backed by another currency, eg the United States dollar.

When a currency board makes a currency convertible at a fixed exchange rate to some weight of gold then the system is referred to as a gold standard.
