Exchange rate

Units of a country's currency per US dollar, averaged over the year.

The official exchange rate is how many units of a country's currency one US dollar bought, averaged over the year, as the central bank or the market set it. A rising line means the currency weakened. The World Bank takes the rates from the IMF's International Financial Statistics. Rates are in today's units: Brazil's early values are in reais although the real only existed from 1994, and eurozone countries show the euro before 1999, converted at their fixed rates.
