Currency
Certain currencies are said to be "pegged" or "fixed" to something, usually another currency. A fixed or pegged currency is one that has a constant value compared to what it is pegged to. For example, the Cape Verdian escudo is pegged to the Euro. If the value of the Euro goes up 1% compared to another form of currency, the value of the escudo also goes up 1% compared to that same currency.
