The Caribbean guilder (code: XCG;[1] abbreviation: Cg; Dutch: Caribische gulden; Papiamento: florin karibense) is a planned currency of Curaçao and Sint Maarten, two constituent countries of the Netherlands, officially slated for introduction in 2025.

The currency has an official launch scheduled for 31 March 2025 and will become the sole legal tender in the countries after 30 June 2025.

The Central Bank of Curaçao and Sint Maarten has announced its official abbreviation as Cg.[1][4].

[6] As the BES islands (Bonaire, Sint Eustatius and Saba) adopted the U.S. dollar directly on 1 January 2011, the introduction of the CMg would have meant the end of the circulation of the Netherlands Antillean guilder.

[8] Former Curaçao MP Alex David Rosaria said that a major problem with the proposed union was the lack of a forum to discuss macroeconomic coordination (as there is for the Eastern Caribbean dollar).

[9] In 2018 the finance minister of Sint Maarten stated that there were only two years of reserve Antillean guilder banknotes remaining and that the islands would need to make a decision soon.

[11] In November 2019, Curaçao Minister of Finance Kenneth Gijsbertha confirmed the introduction of the Caribbean guilder in 2021,[12] and the Central Bank officially announced it a year later.
