The article looks at what makes Bangladeshi private commercial banks profitable. They studied factors like bank size, capital, assets, and the economy. They found that having enough capital, managing assets well, and a growing economy all help banks make more money. Good asset quality, enough cash on hand, and lots of deposits also boost profits. But having high costs and being too big can hurt profits. The study suggests that Bangladesh's financial authorities should keep supporting the banking industry to help the country's economy grow and improve people's lives.
