Dollar rates have risen in Bangladesh's open market, alongside an upward trend in bank and interbank transactions.
Several money exchangers in Motijheel were buying dollars at Tk126.00 to Tk126.40 and selling them at Tk126.70 to Tk126.80.
About a month earlier, open-market dollar rates were between Tk125.00 and Tk125.20.
Bangladesh Bank's cited figures put the interbank rate at Tk123.81 per dollar and the spot-market rate at Tk123.77.
The cited spot-market rate was Tk122.85 a month earlier.
Some banks were said to be paying up to Tk123.95 per dollar to settle letters-of-credit liabilities.
Market participants linked the pressure to higher import bills, slower export earnings and a recent easing in remittance inflows.
Bangladesh Bank figures cited import spending of about $64 billion in July-May of fiscal year 2025-26, up 6.26 percent from a year earlier, while export earnings were about $40 billion, down nearly 2 percent.
Remittances totaled a reported $35.59 billion in fiscal year 2025-26, while monthly inflows fell to $2.82 billion in June and $2.86 billion in July after six consecutive months above $3 billion.
Bangladesh Bank was reported to have instructed commercial banks orally not to push rates higher through competition and set a Tk123.82 maximum buying rate for interbank transactions and remittance collection.
