Bangladesh Bank on Tuesday sent a letter to Swiss Financial Intelligence Unit expressing interest to sign a memorandum of understanding on exchanging information about money laundering. The BB took the move in a bid to collect information about money deposited by Bangladeshi citizens with the Swiss banks, said officials of the central bank. The recent data of Swiss National Bank showed that deposits by Bangladeshi citizens at various Swiss banks rose to Tk 3,236 crore (372 million Swiss francs) at the end of 2013, from Tk 1,991 crore in 2012. A BB official told New Age on Tuesday that the central bank earlier requested the Swiss Financial Intelligence to sign a MoU when Bangladesh became a member country of Egmont Group in July 2013, but the SFI was yet to make any response. BB executive director and spokesperson M Mahfuzur Rahman told New Age on Tuesday that the central bank had proposed again that the MoU should be signed between Bangladesh Financial Intelligence Unit of BB and Swiss Financial Intelligence Unit.
