Banks can create more money by lending out money from customer deposits. When banks receive deposits from customers, they keep a fraction of these deposits as cash reserves and lend out the rest to borrowers. This loan is then deposited in another bank account and the process continues. As banks keep making loans, they create new money in the economy. This is known as the money multiplier effect. The more deposits banks receive and lend out, the more money they can create. Therefore, accepting more deposits from customers and lending out money from those deposits is one of the ways banks can create more money.
