The North Borneo Federation, also known as North Kalimantan or Negara Kesatuan Kalimantan Utara in Malay, was a proposed political entity which would have comprised the British Colonies of Sarawak, British North Borneo (now known as the Malaysian state of Sabah) and the protectorate of Brunei. In 1956, the governments of Sarawak, North Borneo and the State of Brunei announced that they would abandon the Malayan dollar and adopt a common currency of their own, but that never came into being.
