The Bangladesh Bank on Monday purchased $353 million from 26 commercial banks through multiple auction methods as part of its ongoing strategy to curb the depreciation of the US dollar against the taka and revitalise the remittance and export sectors.

The central bank set a cut-off rate of Tk121.75 for these dollar purchases, according to the BB data.

The Bangladesh Bank has bought a total of $1,747.50 million from commercial banks till now of the fiscal year 2025-26.

Talking to the news agency, a senior official of the central bank said BB has intervened in the market by purchasing US dollars from commercial banks through an auction aiming to keep the exchange rate of the taka against the greenback stable.

He also said the central bank will sell the US dollar to banks through similar auctions if the exchange rate of the greenback increases against the local currency.

"We may consider intervening in the market whenever necessary to ensure stability in the exchange rate of the US dollar against the local currency," he added.
