context: Lastly, countries may implement a "gold exchange standard", where the government guarantees a fixed exchange rate, not to a specified amount of gold, but rather to the currency of another country that uses a gold standard. This creates a "de facto" gold standard, where the value of the means of exchange has a fixed external value in terms of gold that is independent of the inherent value of the means of exchange itself.
