Agio
Agio is a term used in commerce for exchange rate, discount or [|premium].
Exchange rate
The variations from fixed par values or rates of exchange in the currencies of different countries. For example, in most countries that used the gold standard, the standard coin was kept up to a uniform point of fineness. In particular, a freshly minted English sovereign was in a fixed relation to freshly minted coins of other countries: 1 £ = 25.221 francs = 20.429 marks = US$4.867, etc.This rate, known as the mint par of exchange, did not necessarily coincide with the corresponding market exchange rates. The balance of trade between the countries determined the actual rate of exchange. If England has a negative balance of trade with France, for instance, currency of equal magnitude is remitted to France, which thus creates a demand for French currency. Procurement of that currency involves payment of a premium referred to as agio. It refers to exchange rate.
