The highest investment commitment came from United Commercial Bank followed by Rupali, Pubali and Janata.
As of December 10, lenders had invested Tk 700 crore in the market but the additional investment will likely to flow into the market in the coming months, according to central bank data.
The move comes at a time when local banks are facing excess liquidity due a lack of demand for loans because of a possible second wave of the pandemic.
The Covid-19 outbreak is also affecting investment decisions, because of which prices of many stocks are staying relatively low.
"We have decided to invest in the stock market as many scripts are still lucrative and it might be profitable if the investment can continue for a long time," said a top official of a scheduled bank, preferring anonymity.
