Taka saw the eighth depreciation this year as its value fell by Tk 1.60 to Tk 91.50 against the US dollar.
The currency is facing depreciation pressure as the supply of US dollars has narrowed owing to higher import bills against moderate export and remittance receipts.
In such circumstances, the central bank on Thursday decided that the exchange rate be determined by the natural course of demand and supply of the American greenback.
Earlier on May 29, Bangladesh Bank depreciated Taka by 1.25 per cent to Tk 89 per US dollar.
