Saint Lucia: Currency & Financial System

Saint Lucia uses the Eastern Caribbean dollar (EC$), the shared currency of the Eastern Caribbean Currency Union, whose other members are Antigua and Barbuda, Dominica, Grenada, Saint Kitts and Nevis, Saint Vincent and the Grenadines, and the British territories of Anguilla and Montserrat. The Eastern Caribbean dollar was introduced in 1965 as the successor to the British West Indies dollar, and as of 2026 it remains pegged to the US dollar at a fixed rate of EC$2.70 to US$1, a rate that has held since July 1976.

Monetary policy for the currency union is set not by a national central bank but by the Eastern Caribbean Central Bank (ECCB), which is headquartered in Basseterre, Saint Kitts and Nevis, and which licenses and supervises commercial banks across all eight members of the union, including Saint Lucia. Because the long-standing peg leaves little room for an independent interest rate or exchange rate policy, the ECCB's role centers on maintaining the foreign reserve backing that supports the fixed rate, and the US dollar circulates widely alongside the EC dollar in everyday commerce on the island.

Beginning in the late 1990s and early 2000s, Saint Lucia developed an offshore financial services sector to diversify its economy beyond agriculture and tourism, anchored by the International Business Companies Act of 1999 and the International Trusts Act of 2002, which allowed the registration of international business companies and trusts for non-resident clients. Offshore banking and other international financial services are supervised by the Financial Services Regulatory Authority, which licenses international banks, trust providers, and registered agents, while the Registry of Companies and Intellectual Property maintains the corporate register. In response to international tax transparency pressure, Saint Lucia enacted an Economic Substance Act in 2019 requiring companies to demonstrate genuine local activity, and the country was removed from the European Union list of non-cooperative tax jurisdictions in 2021. As of 2026, the domestic banking system remains small, with the US dollar continuing to circulate widely alongside the EC dollar in private commerce.
