Global Currency Exchange Rates
Official exchange rates for converting more than 160 world currencies into US dollars.
A dated table of official foreign currency exchange rates published by the US Treasury, covering every currency the US government transacts in. Each row gives a country, its currency, the effective date and the rate used to convert that currency into US dollars. Finance, accounting, invoicing and cross-border commerce teams use it as an auditable, government-sourced alternative to commercial FX feeds.
