$

Since 1967, the Sultanate of Brunei has used the Brunei dollar as its official medium of exchange. In order to distinguish it from other currencies denominated in dollars, it is typically abbreviated with the dollar symbol $ or, alternatively, B$. Each penny is divided into 100 sen. The Autoriti Monetari Brunei Darussalam is responsible for printing the Brunei dollar. The Brunei dollar and Singapore dollar are interchangeable at par as a result of a currency interchangeability agreement from 1967. As a result, both the Singapore dollar and the Brunei dollar are recognized as "customary tender" in both countries.
