The Bangladesh taka weakened in interbank trading on Thursday on demand for US dollars for import payments, dealers said.
The taka was quoted at 59.05/59.10 per dollar against 58.75/59.10 on Tuesday.
"Only a limited amount of dollars was available in the market and we needed to make payment against imports," said a dealer with a foreign bank.
He said one bank sold a few million dollars while other banks refrained from selling, as the forex market in New York was closed on Thursday for New Year celebrations.
Bangladeshi banks maintain foreign currency accounts with banks in New York. The market in Bangladesh was closed on Wednesday for a year-end bank holiday.
The call rates dropped to between 4.0 percent and 8.10 percent against 7.0-10 percent on Tuesday.
