The ECB said at the weekend that privately held ABLV is likely unable to pay its debts or other liabilities as they fall due.

"We believe our bank will be able to settle with all of our clients in full," ABLV, Latvia's third-biggest bank by assets, said in a statement.

"Voluntary liquidation is an important condition for it – the process has to be done as professionally and as transparently as possible, given the history of Latvian insolvency and liquidation processes."

ABLV, whose customers are mostly residents of the Commonwealth of Independent States, was accused by U.S. authorities of large-scale money laundering this month, leading clients to pull money from the bank.

ABLV denies the accusations.

Most domestic lending in Latvia is conducted by Nordic banks such as Sweden's SEB and Swedbank. Many of Latvia's other banks are funded mainly from deposits by non-residents and have only limited domestic lending operations.
