The central bank set a cut-off rate of Taka 121.75 for these dollar purchases, according to the central bank data.
Talking to BSS, 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 BDT against the greenback stable.
He also said the central bank will sell the US dollar to banks through similarly auction if the exchange rate of the greenback increases against the local currency, reports UNB.
"We may consider intervening in the market whenever necessary for ensuring the exchange rate of the US dollar against the local currency remaining stable," he added.
