The Eastern Caribbean dollar is the currency of all seven full members and one associate member of the Organisation of Eastern Caribbean States (OECS). The successor to the British West Indies dollar, it has existed since 1965, and it is normally abbreviated with the dollar sign $ or, alternatively, EC$ to distinguish it from other dollar-denominated currencies. The EC$ is subdivided into 100 cents. It has been pegged to the United States dollar since 7 July 1976, at the exchange rate of US$1 = EC$2.70.

The Organisation of Eastern Caribbean States is an inter-governmental organisation dedicated to economic harmonisation and integration, protection of human and legal rights, and the encouragement of good governance between countries and territories in the Eastern Caribbean. It also performs the role of spreading responsibility and liability in the event of natural disaster.
