The Bank of St. Helena has a branch on the island; it holds an account with the UK's Lloyds Bank for the purposes of conducting money transfers with the rest of the world. The currency on Ascension Island is the Saint Helena pound. Tristan da Cunha however uses the pound sterling rather than the Saint Helena pound. The coins of the Saint Helena pound specify that they are for use on both Saint Helena and Ascension Island, but with no mention of Tristan da Cunha, whereas the banknotes only say “Government of St. Helena”. There are also distinct commemorative coins for Ascension island. For more information on currency in the wider region, see Pound sterling in the South Atlantic and the Antarctic.
