The Eastern Caribbean Central Bank (ECCB)[2] is a supranational central bank that serves Anguilla, Antigua and Barbuda, Dominica, Grenada, Montserrat, Saint Kitts and Nevis, Saint Lucia, and Saint Vincent and the Grenadines, all members of the Organisation of Eastern Caribbean States (OECS) that use the ECCB-issued Eastern Caribbean Dollar as their currency.

In 1946, a West Indian Currency Conference saw Barbados, British Guiana, the Leeward Islands, Trinidad and Tobago and the Windward Islands agree to establish a unified decimal currency system based on a West Indian dollar to replace the earlier arrangement of having three different Boards of Commissioners of Currency for Barbados (which also served the Leeward and Windward Islands), British Guiana, and Trinidad & Tobago.

[4][5] in 1950, the British Caribbean Currency Board (BCCB) was set up in Trinidad,[6] with the sole right to issue notes and coins of the new unified currency and given the mandate of keeping full foreign exchange cover to ensure convertibility at $4.80 per pound sterling.

[4] Barbados withdrew from the currency union in 1972, following which the ECCA headquarters were moved to Basseterre in St.

[4] The Eastern Caribbean Central Bank Agreement, signed at Port of Spain on 5 July 1983, established the ECCB as the successor entity of the ECCA, tasked with maintaining the stability and integrity of the subregion's currency and banking system in order to facilitate the balanced growth and development of its member states.
