The unit currency of Bhutan is called Ngultrum which is symbolized as Nu and the currency code is BTN. It has the same value as the Indian rupee and surprisingly the Indian currency is legal in Bhutan with the exception of the recently introduced 500 and 1000 notes. However, the Bhutanese currency cannot be used in India. Ngultrum is the locally and officially acknowledged currency of Bhutan which is used for all national and international economic trades.
