Ex-soviet state Latvia – which became a fully-fledged member of the euro zone on Wednesday – has hit back at claims that it could become a haven for "dirty money".
Latvia's regulator, the Financial and Capital Market Commission (FCMC), moved to alleviate any concerns over the country's banking sector and downplayed a decision by JPMorgan to stop clearing U.S.-dollar transfers for the nation's lenders.
"JPMorgan's decision to reduce the amount of operations is due to the U.S. bank's strategy shift in the interbank market in the world. It is not connected with Latvia or Latvian banking sector," the organization said in a press release on Wednesday. JPMorgan was not immediately available for comment when contacted by CNBC.

Martins Bicevskis, the president of the Association of Latvian Commercial Banks added his voice to the response declaring that anti-money laundering and terrorism financing is the same for all EU member states.
"Any speculations regarding the amounts of 'dirty money' that could increase with Latvia joining (the) euro zone is not only unjustified, but also is in sharp contrast with the existing supervision of financial system," he said in the same press release.

The Baltic nation joined the 17 nation bloc this week despite previous concerns from the European Central Bank over the reliance of its banking sector on non-resident deposits as a source of funding. Added to this, there have been accusations that this non-resident cash is mainly flowing from neighboring country Russia.

Mark Galeotti, a professor at New York University who researches organized crime in the former Soviet Union told the AP news agency on Tuesday that he expected a "spike in dubious money flowing in" after it had joined the currency bloc.
A spokesperson for the FCMC told CNBC via email that the introduction of the euro will raise confidence about the stability of the Latvian banking sector and will not be the main driving force for a rise in non-resident deposits.
Nearly 50 percent of deposits in Latvian banks were held by non-residents in 2012, according to FCMC statistics. Whilst this is not the highest it has been, it has risen from a low of 38 percent in 2009 after being hit hard by the global financial crisis the year before. In November 2013, non-resident deposits had increased by approximately 513 million euros year-on-year, the FCMC told CNBC, adding that the 6 percent increase showed a "considerably" slower pace of increase than in the previous years.
