BRUSSELS -- Croatia has submitted a formal bid to join the European Exchange Rate Mechanism (ERM-2), an early stage on the path to membership of the euro currency, the head of the Eurogroup of euro zone finance ministers said on Monday.

The move could allow the Balkan country to join the euro currency zone, which currently comprises 19 states, at the earliest in 2023, an EU official said.

Commitments offered by Croatia in a letter were welcomed by the bloc’s finance ministers at a meeting on Monday, the chair of the meeting Mario Centeno told a news conference.

EU economics commissioner Pierre Moscovici said Zagreb’s move was a “vote of confidence in the euro.”

Croatia has committed to preparing the ground for the European Central Bank to take over banking supervision in the country. It has also committed to applying reforms on anti-money laundering rules and to making the public administration more effective and less costly, an EU statement said.

The ECB and the European Commission will monitor the application of these commitments in a process that is expected to last one year.
